What Are You Really Putting Into Your Body? A Transparent Look Inside

Every day, millions of people worldwide take dietary supplements hoping to support their health, vitality, and well-being. The global supplements market continues to grow exponentially, valued at around $203 billion in 2025 and projected to almost double by 2034. Consumers are seeking options to fill nutritional gaps caused by modern diets, hectic lifestyles, and rising health awareness. Yet, in this booming market, many still do not know what they are truly putting into their bodies.

The supplement industry comprises more than 100,000 products with varying degrees of quality, transparency, and scientific support. While some players prioritize genuine science and consumer care, many brands focus more on flashy marketing, quick sales, and investor interests. This reality matters because not all supplements are created equally, and the differences can affect both health outcomes and your wallet.

The Reality Behind Many Supplements

Independent studies and regulatory reviews reveal a number of concerning issues in the broader supplement market:

Label Misinformation: What’s in the bottle isn’t always what’s on the label. In one study of weight loss supplements, the vast majority (80%) of products analyzed had ingredients listed on the label that were not detected through lab analysis. This discrepancy raises questions about manufacturing standards and erodes consumer trust.
Poor Bioavailability: Many supplements use immediate-release delivery forms—meaning large doses are delivered at once. The trouble is, this can lead to waste—especially with high amounts of water-soluble nutrients like B vitamins and vitamin C. The body can only absorb a certain amount at one time; the rest get flushed out in urine. This not only diminishes effectiveness but leads to wasted money and effort.
Ownership and Influence: A large share of supplement brands are owned by pharmaceutical companies or venture-backed investors emphasizing profits and market share over quality and transparency.
Lack of Independent Research: Many products rely on internal or unverified studies, with limited peer-reviewed publications to substantiate their efficacy claims.

The cumulative effect is that consumers may be spending heavily on supplements that are unlikely to deliver consistent or meaningful results, while also risking exposure to poor-quality ingredients.

The ENDUR™ Brand: A Family Legacy of Transparency and Science

The ENDUR brand hails from a proud family-owned and operated business established in 1978. It stands in stark contrast to many firms driven by venture capital or pharmaceutical conglomerates. Founded by Terry Hammerschmidt, an expert in biochemistry and nutritional formulation, the ENDUR brand was created with a vision to offer supplements that align with how the body naturally processes nutrients (like food digestion).

Terry recognized early that “mega-dose” supplements and immediate-release formulas often resulted in nutrient spikes followed by losses, leading to inferior absorption and reduced value to consumers. Instead, ENDUR tablets release nutrients in a slow and steady manner over several hours using a proprietary controlled-release method, designed to enable gradual release that promotes absorption.

The Science of Controlled-Release Delivery: Optimal Absorption, More Value

ENDUR controlled release formulations allow vitamins, minerals, and specialty nutrients to be released over several hours, closely mimicking the body's natural nutrient absorption rhythms. This means:

Optimal bioavailability: Nutrients are able to stay available longer in the digestive tract for optimal uptake and tissue retention, reducing waste.
More comfort: Controlled-release delivery— especially the ENDUR form—helps promote digestive comfort. For niacin supplements, it’s a real lifesaver for many, as the vegetable wax-matrix tablet core is highly effective at helping to eliminate nuisance skin flushing so common with regular immediate-release niacin.
Cost savings: Because nutrients are absorbed more efficiently, consumers often need lower doses or fewer pills, making each purchase more cost-effective.

Peer-reviewed studies validate these benefits. In one systematic review, published in the American Journal of Clinical Nutrition, university researchers compared controlled-release niacin to immediate-release versions and found the controlled-release forms significantly improved tolerability and steady-state blood levels. In other words, slow-release supplements help maintain consistent nutrient levels throughout the day, which is important for metabolic functions and overall benefits.

The ENDUR controlled-release approach has been independently researched for decades and is well documented—not a marketing claim but a scientific fact supported by more than 20 clinical, analytical, pharmacokinetic, and other studies published in the scientific journals.

Why Transparency Matters: The ENDUR Promise

In a market where some companies make questionable claims, use confusing labels with proprietary blends, or ingredients in less-than-effective amounts, the ENDUR promise of full transparency is more important than ever:

Ingredient disclosure: Every product lists all components and importantly, the amounts of all active ingredients clearly.
Research availability: Independent, peer-reviewed studies supporting their products are accessible to consumers for review.
No disease claims: ENDUR adheres strictly to DSHEA guidelines, focusing on supporting normal body functions without making any claims about curing or preventing diseases.
Family-owned, no outside investors: This independence ensures a commitment to quality and integrity, not just sales or stock prices.

The ENDUR Cost-Saving Advantage

While some may believe high-quality supplements must cost more, ENDUR supplements provide real value through:

Efficient absorption: High bioavailability means you get more benefit per dose, reducing the need for excessive consumption.
Direct sales: Buying directly from official channels that sell ENDUR products avoids markup fees, middlemen, and counterfeit risks.
Subscription savings and deals: Regular customers can access discounts and exclusive promotions, further lowering costs.

In other words, ENDUR products support health goals without putting a strain on the budget.

The Growing Supplement Market: Why Demand Is Rising

The supplement industry is flourishing due to:

Global soil degradation: Increasing concerns that the degradation of soil fertility is resulting in less nutrient-dense foods is driving more people to supplement to fill potential nutrient gaps for essential vitamins and minerals.
Aging population: Older adults are increasingly using supplements for health maintenance.
Preventive health trends: People are seeking to help maintain optimal health by supporting normal function with nutrition.
Increased awareness of nutrient gaps: Modern diets often lack key vitamins and minerals, boosting demand for supplements.
Fitness and wellness culture: More individuals are embracing active lifestyles, fueling demand for athlete-grade supplements like the original formulations in the ENDUR product line.

With the dietary supplement market expanding rapidly, it’s crucial for consumers to stay informed so they can choose products that offer real value. It starts with prioritizing product quality, company ethics, and transparency.

Choosing Wisely: 7 Questions to Ask Before Buying Supplements

Who owns and controls the company making the product?
Are ingredient sources and amounts clearly disclosed on labels?
Are ingredients in amounts shown to be effective?
Is the product made using manufacturing practices aligned with current Good Manufacturing Practices (cGMPs)?
Are research studies peer-reviewed and transparent?
Is nutrient delivery designed for steady absorption and minimal waste?
Are claims consistent with DSHEA rules and free from claims to treat a disease?

Selecting supplements that answer “yes” to these questions empowers consumers to invest wisely in their health.
