Why Multivitamins Are Booming in 2025–2026

The multivitamin category continues to be the backbone of the dietary‐supplement market. According to recent market data, multivitamins make up roughly 41–46% of the overall vitamin market in North America.  Growth is being fueled by a mix of factors: heightened health awareness, economic uncertainty pushing consumers toward “all-in-one” solutions, and rising interest in prevention rather than treatment.  Also important: newer supplement formats beyond pills — such as gummies, chewables, liquids — are becoming more mainstream. These formats appeal especially to people who dislike swallowing pills and prefer more palatable or convenient delivery. 

Given those dynamics, 2026 is shaping up to be a strong year for multivitamins — especially for brands and products that combine convenience, targeted formulations (e.g., by age, gender, lifestyle), and evidence of quality.

What Trends Are Shaping Multivitamin Popularity

Personalized & Targeted Nutrition — More consumers now look for multivitamins tailored to their gender, age, life stage (e.g., prenatal, 50+, active adult) or specific health goals (e.g., bone health, energy, immune support). This segmentation helps multivitamins stay relevant amid growing interest in individualized health.  Clean-label, Whole-food & “Natural” Ingredients — There’s rising demand for vitamins derived from whole-food sources, with non-GMO, organic, or plant-based credentials. This appeals especially to people wary of synthetic nutrients.  Easier-to-take Formats — Gummies, chewables, and liquid multivitamins are increasingly popular because of convenience and user experience. These forms help reduce “pill fatigue” and broaden appeal beyond traditional supplement users.  Focus on Key Vitamins & Minerals — Among single-nutrient supplements, demand for certain minerals and vitamins — like magnesium, vitamin C, vitamin D, B vitamins — has surged. 

Leading Multivitamin Products & Brands in 2025–2026

While many products compete in the multivitamin space, a handful consistently stand out in terms of sales, consumer reviews, and marketing presence. Here are some of the most-popular, widely advertised, and best-selling ones today:

Centrum – Especially its “Silver” and adult-targeted lines. Centrum remains among the top multivitamin sellers in the U.S., with products commonly formulated for age or gender-specific needs (e.g., adults 50+, men’s or women’s health).  Nature Made – Known for affordability and broad availability, Nature Made offers multivitamins and single-vitamin supplements. It’s often mentioned among top brands consumers trust for basic nutrient support.  Garden of Life – A top pick for those seeking whole-food–based, non-GMO, and cleaner-label multivitamins. Their gender- and lifestyle-specific formulas cater especially to health-conscious and/or vegetarian/vegan users.  Vitafusion – A leader in the gummy / chewable multivitamin category. Appeals to consumers who prefer more palatable, candy-like supplements instead of pills.  Pure Encapsulations – Favored among users who need hypoallergenic or allergen-free supplements, or who prefer minimalist formulations — often chosen by people with sensitivities or strict dietary preferences. 

In addition to individual brands, there’s a rising segment of specialty and personalized-nutrition players offering custom multivitamin packs based on lifestyle, diet, or even genetic testing. This reflects a broader shift in the supplement industry toward personalization and transparency. 

What to Watch in 2026 — What’s Likely to Rise (or Fall) in Popularity

Expect a stronger push toward subscription-based vitamin services, especially ones delivering tailored vitamin blends depending on age, gender, activity level, or health goals. Personalized nutrition is increasingly mainstream.  Gummies, liquids, chewables — not pills — will continue gaining market share. As supplement users expand beyond traditional “health-nuts,” palatability and convenience become key.  Demand for clean-label, plant-based, non-GMO supplements will keep rising, especially among younger, health-conscious demographics.  We’ll likely see more blends that combine vitamins/minerals with other wellness ingredients (e.g., probiotics, herbal extracts, antioxidant complexes) — especially as consumers look for “everything-in-one” convenience.  That said: as scrutiny increases on supplement quality and marketing claims, products that don’t deliver on transparency or quality may fall out of favor. Clean ingredient sourcing, third-party testing, clear labeling — these will likely become non-negotiable for many buyers. 

A Word of Caution

While multivitamins are popular and sometimes heavily advertised — and while the idea of “covering all your nutritional bases” with one pill or gummy is appealing — the reality is more nuanced:

Not everyone needs a full-spectrum multivitamin. The benefit depends heavily on diet, lifestyle, and specific nutritional gaps. Over-supplementation can also be a concern. Some vitamins or minerals — especially fat-soluble ones or minerals taken in high doses — can accumulate and cause adverse effects over time. Quality matters. The difference between a cheap mass-market vitamin and a high-quality, transparently sourced product can be substantial (in ingredient purity, bioavailability, absence of fillers/contaminants).

It’s always wise to consult a medical professional or a registered dietitian before starting any long-term supplement regimen, especially if you have health conditions or dietary restrictions.

Final Thoughts

As we head into 2026, the multivitamin space remains strong — and likely to get even more diverse. Whether you prefer classic pills, easy-to-swallow gummies, clean-label whole-food formulas, or fully personalized vitamin packs, there’s more choice than ever.

Whether you’re a blogger, YouTuber, web developer, or social media creator, learning how to offer ad space can turn your digital presence into a steady income stream.

In this guide, we’ll explore:

What online ad space is How to create ad space on websites or platforms How to make money from it Tips to increase your earnings

🖥️ What Is Online Ad Space?

Online ad space refers to areas on digital platforms (websites, apps, videos, emails, etc.) where businesses can display advertisements. These ads can be in the form of banners, video clips, pop-ups, text links, or sponsored content.

Common platforms that sell ad space include:

Websites and blogs YouTube channels Newsletters Podcasts Social media profiles/pages

🛠️ How to Create Ad Space Online

Here’s how to get started with building and offering ad space:

1. Start a Website or Blog

This is the most traditional way to host ad space.

Use platforms like WordPress, Wix, Squarespace, or custom HTML. Focus on a niche (e.g., travel, tech, health, finance). Publish regular, quality content to grow traffic.

2. Join an Ad Network

These platforms connect publishers (you) with advertisers.

Google AdSense – beginner-friendly and widely used. Ezoic – offers higher CPM with growing traffic. Media.net, PropellerAds, and AdThrive are other options.

3. Designate Visible Ad Slots

Add banners in high-traffic areas:

Header Sidebar Within blog posts Footer Pop-ups (sparingly)

Many themes and plugins (like Ad Inserter or WP-Insert) help manage ad placement easily.

4. Use YouTube or Social Media

You don’t need a site to sell ad space.

Platforms like:

YouTube – Ads via Google AdSense (YouTube Partner Program) Instagram/TikTok – Brand partnerships or affiliate links Email newsletters – Offer ad spots or sponsored mentions Try platforms like Substack, Beehiiv, or ConvertKit for newsletter monetization.

💸 How to Make Money from Ad Space

There are several ways to generate income from your ad inventory:

1. Pay-Per-Click (PPC)

You earn money every time someone clicks an ad. Google AdSense is the most popular PPC platform.

2. Cost Per Mille (CPM)

You earn based on every 1,000 ad impressions (views), whether the user clicks or not. This is great for high-traffic sites.

3. Affiliate Marketing

Instead of displaying regular ads, you promote products/services with special tracking links. You get paid when someone makes a purchase through your link.

4. Direct Ad Sales

You can offer ad spots directly to businesses.

Set a monthly or weekly price Use tools like BuySellAds or build a “Media Kit” to pitch sponsors

5. Sponsored Content

Brands pay you to publish a blog post, review, video, or story that promotes their product.

📈 Tips to Maximize Ad Revenue

Increase traffic through SEO, social sharing, and mailing lists Use heatmaps (like Hotjar) to see where users engage most A/B test ad positions and sizes Focus on high-paying niches (finance, legal, tech, real estate) Create valuable, sticky content that keeps people on your site longer

🧠 Final Thoughts

Monetizing online ad space isn’t just for major publishers. With the right setup and strategy, even small creators can build meaningful income over time. It takes consistency, analytics, and creativity—but once your platform gains traction, your ad space becomes a powerful asset that works for you 24/7.

Kubernetes introduction

Kubernetes (commonly stylized as K8s) is an open-sourcecontainer-orchestration system for automating computer application deployment, scaling, and management. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of database management systems”. It works with a range of container tools and runs containers in a cluster, often with images built using Docker. Kubernetes originally interfaced with the Docker runtime through a “Dockershim”; however, the shim has since been deprecated in favor of directly interfacing with the container through containerd, or replacing Docker with a runtime that is compliant with the Container Runtime Interface (CRI) introduced by Kubernetes in 2016.

Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

Kubernetes API

The design principles underlying Kubernetes allow one to programmatically create, configure, and manage Kubernetes clusters. This function is exposed via an API called the Cluster API. A key concept embodied in the API is the notion that the Kubernetes cluster is itself a resource / object that can be managed just like any other Kubernetes resources. Similarly, machines that make up the cluster are also treated as a Kubernetes resource. The API has two pieces – the core API, and a provider implementation. The provider implementation consists of cloud-provider specific functions that let Kubernetes provide the cluster API in a fashion that is well-integrated with the cloud-provider’s services and resources.

Kubernetes uses

Kubernetes is commonly used as a way to host a microservice-based implementation, because it and its associated ecosystem of tools provide all the capabilities needed to address key concerns of any microservice architecture.

7 tips for improving load speed

Plan for performance

Are you building a new website? Be sure to discuss the importance of performance early on and set targets. That way, you have a faster load speed from the beginning and don’t have to implement fixes later.

Step 1: test, step 2: test…

Are you seeing a pattern here? 😉 Testing is crucial! Before you launch, load and test your website multiple times to make sure you can handle the traffic of real site visitors. This is especially important for sites with complex hosting, such as load-balanced configuration.

Implement some “quick wins”

To be clear, there’s no “get fast quick” scheme for site load speeds. But there is a tried-and-true template that will put you ahead of the curve. That includes making use of modern image formats, enabling compression on the server via Gzip, and leveraging browser cache. Find some more low-hanging fruit here.

Careful of your images!

Good websites have great graphic content – but they also take into account how images impact load speed. You can improve image performance by considering file formats, image compression, and lazy loading.

Think of the mobile visitors

More and more people surf the web on their phone these days, which makes mobile-optimized sites a huge priority! Since mobile users tend to use slower, less stable Internet connections, Accelerated Mobile Pages (AMPs) are a great way to get them content faster.

Prioritize above-the-fold

First impressions matter – and your above-the-fold content can make or break them! Consider inline styling for above-the-fold, then loading your code in chunks. This type of asynchronous loading can create a faster perceived load time for the user.

Assess your external scripts

Third-party scripts are a great tool – but can make your website feel a little crowded. Assess the performance of external scripts on your site load speed, and replace or remove those that are negatively impacting user experience.

DevOps preface

If you’re old, don’t try to change yourself, change your environment. —B. F. Skinner

One view of DevOps is that it helps take on that last mile problem in software: value delivery. The premise is that encouraging behaviors such as teaming, feedback, and experimentation will be reinforced by desirable outcomes such as better software, delivered faster and at lower cost. For many, the DevOps discourse then quickly turns to automation. That makes sense as automation is an environmental intervention that is relatively actionable. If you want to change behavior, change the environment!

In this context, automation becomes a significant investment decision with strategic import. DevOps automation engineers face a number of design choices. What level of interface abstraction is appropriate for the automation tooling? Where should you separate automation concerns of an infrastructure nature from those that should be more application centric?

These questions matter because automation tooling that is accessible to all can better connect all the participants in the software delivery process. That is going to help fos‐ ter all those positive teaming behaviors we are after. Automation that is decoupled from infrastructure provisioning events makes it possible to quickly tenant new project streams. Users can immediately self-serve without raising a new infrastructure requisition.

We want to open the innovation process to all, be they 10x programmers or citizen developers. Doing DevOps with makes this possible, and this blog will show you how.

This is a practical guide that will show how to easily implement and automate powerful cloud deployment patterns using. The container management platform provides a self-service platform for users. Its natively container-aware approach will allow us to show you an application-centric view to automation.

Why is testing necessary?

Rigorous testing of components and systems, and their associated documentation, can help reduce the risk of failures occurring during operation. When defects are detected, and subsequently fixed, this contributes to the quality of the components or systems. In addition, software testing may also be required to meet contractual or legal requirements or industry-specific standards.

Testing’s contributions to success

Throughout the history of computing, it is quite common for software and systems to be delivered into operation and, due to the presence of defects, to subsequently cause failures or otherwise not meet the stakeholders’ needs. However, using appropriate test techniques can reduce the frequency of such problematic deliveries, when those techniques are applied with the appropriate level of test expertise, in the appropriate test levels, and at the appropriate points in the software development lifecycle. Examples include:

  • Having testers involved in requirements reviews or user story refinement could detect defects in these work products. The identification and removal of requirements defects reduces the risk of incorrect or untestable features being developed.
  • Having testers work closely with system designers while the system is being designed can increase each party’s understanding of the design and how to test it. This increased understanding can reduce the risk of fundamental design defects and enable tests to be identified at an early stage.
  • Having testers work closely with developers while the code is under development can increase each party’s understanding of the code and how to test it. This increased understanding can reduce the risk of defects within the code and the tests.
  • Having testers verify and validate the software prior to release can detect failures that might otherwise have been missed, and support the process of removing the defects that caused the failures (i.e., debugging). This increases the likelihood that the software meets stakeholder needs and satisfies requirements.

Quality assurance and testing

While people often use the phrase quality assurance (or just QA) to refer to testing, quality assurance and testing are not the same, but they are related. A larger concept, quality management, ties them together. Quality management includes all activities that direct and control an organization with regard to quality. Among other activities, quality management includes both quality assurance and quality control. Quality assurance is typically focused on adherence to proper processes, in order to provide confidence that the appropriate levels of quality will be achieved. When processes are carried out properly, the work products created by those processes are generally of higher quality, which contributes to defect prevention. In addition, the use of root cause analysis to detect and remove the causes of defects, along with the proper application of the findings of retrospective meetings to improve processes, are important for effective quality assurance.

Quality control involves various activities, including test activities, that support the achievement of appropriate levels of quality. Test activities are part of the overall software development or maintenance process. Since quality assurance is concerned with the proper execution of the entire process, quality assurance supports proper testing.

Errors, Defects, and Failures

A person can make an error (mistake), which can lead to the introduction of a defect (fault or bug) in the software code or in some other related work product. An error that leads to the introduction of a defect in one work product can trigger an error that leads to the introduction of a defect in a related work product. For example, a requirements elicitation error can lead to a requirements defect, which then results in a programming error that leads to a defect in the code.

If a defect in the code is executed, this may cause a failure, but not necessarily in all circumstances. For example, some defects require very specific inputs or preconditions to trigger a failure, which may occur rarely or never.

Errors may occur for many reasons, such as:

  • Time pressure
  • Human fallibility
  • Inexperienced or insufficiently skilled project participants
  • Miscommunication between project participants, including miscommunication about requirements and design
  • Complexity of the code, design, architecture, the underlying problem to be solved, and/or the technologies used
  • Misunderstandings about intra-system and inter-system interfaces, especially when such intra- system and inter-system interactions are large in number
  • New, unfamiliar technologies

In addition to failures caused due to defects in the code, failures can also be caused by environmental conditions. For example, radiation, electromagnetic fields, and pollution can cause defects in firmware or influence the execution of software by changing hardware conditions.

Not all unexpected test results are failures. False positives may occur due to errors in the way tests were executed, or due to defects in the test data, the test environment, or other testware, or for other reasons. The inverse situation can also occur, where similar errors or defects lead to false negatives. False negatives are tests that do not detect defects that they should have detected; false positives are reported as defects, but aren’t actually defects.

Defects, Root Causes and Effects

The root causes of defects are the earliest actions or conditions that contributed to creating the defects. Defects can be analyzed to identify their root causes, so as to reduce the occurrence of similar defects in the future. By focusing on the most significant root causes, root cause analysis can lead to process improvements that prevent a significant number of future defects from being introduced.

For example, suppose incorrect interest payments, due to a single line of incorrect code, result in customer complaints. The defective code was written for a user story which was ambiguous, due to the product owner’s misunderstanding of how to calculate interest. If a large percentage of defects exist in interest calculations, and these defects have their root cause in similar misunderstandings, the product owners could be trained in the topic of interest calculations to reduce such defects in the future.

In this example, the customer complaints are effects. The incorrect interest payments are failures. The improper calculation in the code is a defect, and it resulted from the original defect, the ambiguity in the user story. The root cause of the original defect was a lack of knowledge on the part of the product owner, which resulted in the product owner making an error while writing the user story.

Tasks of a Test Manager and Tester

The activities and tasks performed by these two roles depend on the project and product context, the skills of the people in the roles, and the organization.

The test manager is tasked with overall responsibility for the test process and successful leadership of the test activities. The test management role might be performed by a professional test manager, or by a project manager, a development manager, or a quality assurance manager. In larger projects or organizations, several test teams may report to a test manager, test coach, or test coordinator, each team being headed by a test leader or lead tester.

Typical test manager tasks may include:

  •  Develop or review a test policy and test strategy for the organization
  •  Plan the test activities by considering the context, and understanding the test objectives and risks. This may include selecting test approaches, estimating test time, effort and cost, acquiring resources, defining test levels and test cycles, and planning defect management
  • Write and update the test plan(s)
  • Coordinate the test plan(s) with project managers, product owners, and others
  • Share testing perspectives with other project activities, such as integration planning
  • Initiate the analysis, design, implementation, and execution of tests, monitor test progress and results, and check the status of exit criteria (or definition of done) and facilitate test completion activities
  • Prepare and deliver test progress reports and test summary reports based on the information gathered
  • Adapt planning based on test results and progress (sometimes documented in test progress reports, and/or in test summary reports for other testing already completed on the project) and take any actions necessary for test control
  • Support setting up the defect management system and adequate configuration management of test-ware
  • Introduce suitable metrics for measuring test progress and evaluating the quality of the testing and the product
  • Support the selection and implementation of tools to support the test process, including recommending the budget for tool selection (and possibly purchase and/or support), allocating time and effort for pilot projects, and providing continuing support in the use of the tool(s)
  • Decide about the implementation of test environment(s)
  • Promote and advocate the testers, the test team, and the test profession within the organisation
  • Develop the skills and careers of testers (e.g., through training plans, performance evaluations, coaching, etc.)

The way in which the test manager role is carried out varies depending on the software development lifecycle. For example, in Agile development, some of the tasks mentioned above are handled by the Agile team, especially those tasks concerned with the day-to-day testing done within the team, often by a tester working within the team. Some of the tasks that span multiple teams or the entire organization, or that have to do with personnel management, may be done by test managers outside of the development team, who are sometimes called test coaches.

Typical tester tasks may include:

  • Review and contribute to test plans
  • Analyse, review, and assess requirements, user stories and acceptance criteria, specifications, and models for testability (i.e., the test basis)
  • Identify and document test conditions, and capture traceability between test cases, test conditions, and the test basis
  • Design, set up, and verify test environment(s), often coordinating with system administration and network management
  • Design and implement test cases and test procedures
  • Prepare and acquire test data
  • Create the detailed test execution schedule
  • Execute tests, evaluate the results, and document deviations from expected results
  • Use appropriate tools to facilitate the test process
  • Automate tests as needed (may be supported by a developer or a test automation expert)
  • Evaluate non-functional characteristics such as performance efficiency, reliability, usability,security, compatibility, and portability
  • Review tests developed by others

People who work on test analysis, test design, specific test types, or test automation may be specialists in these roles. Depending on the risks related to the product and the project, and the software development lifecycle model selected, different people may take over the role of tester at different test levels. For example, at the component testing level and the component integration testing level, the role of a tester is often done by developers. At the acceptance test level, the role of a tester is often done by business analysts, subject matter experts, and users. At the system test level and the system integration test level, the role of a tester is often done by an independent test team. At the operational acceptance test level, the role of a tester is often done by operations and/or systems administration staff.

What are the testing objectives?

What should we test in a project may very and testing objective could include:

  • Testing or evaluating work products such as requirements, user stories, design and code.
  • Validated whether the test object is done or complete and work as expected by users and stakeholders.
  • Building confidence that in the quality of the test objective.
  • Preventing errors and defects.
  • Finding defects which lead to failure’s.
  • Providing to stakeholders information to let them make informed decisions, regarding the quality of the object under test.
  • Reducing the risk of the software quality.
  • Complying to legal, or regulatory standards, and verifying that the object under test comply with those standards or requirements.

The objectives under test may very from system to system, depending the context of the component under test, the level of test, and the model of the software development lifecycle being used.

What is testing?

Application or software systems, in this modern age, are all part of life, users all over the world are using and even testing systems with out even knowing that they are part of the testing. In our daily life we are using systems on our phones or our desktops, from banks, cellular providers, medical, ordering food and much more.

Software which does not function properly can lead to many problems, that include loss of money, time, reputation and more. Software testing, which is part of QA, can reduce errors, defects and failure in the software under testing.

Software testing is a process which includes many different activities such as test execution, planing, analysing, designing, implementing tests, reporting progress and results, and evaluate the quality of the object under test.
