An Introduction to Fitness Supplements

Walk into any supplement store and you’ll face a wall of products making bold claims. Fat burners, testosterone boosters, pump enhancers, recovery matrices — the options are overwhelming and the marketing is aggressive.

At Dexter Tenison Fitness, we believe in a food-first approach. But supplements have their place when used correctly. Here’s what you need to know before spending a dime.

What Are Fitness Supplements?

Supplements are products designed to supplement (not replace) your diet. They come in many forms — powders, capsules, liquids, bars — and serve different purposes depending on the ingredient.

The key word is “supplement.” They fill gaps in your nutrition. They don’t replace eating real food.

Who Actually Needs Supplements?

You might benefit from supplements if:

• You train regularly (3+ times per week) and have a solid nutrition foundation
• You have specific nutrient deficiencies identified by bloodwork
• You struggle to hit protein targets through food alone
• You have dietary restrictions that limit nutrient intake

You probably don’t need supplements if:

• Your diet is inconsistent and you’re not training regularly
• You’re looking for a magic pill to replace hard work
• You haven’t dialed in your basic nutrition yet

The Food-First Principle

Before considering any supplement, ask yourself: “Can I get this from food?”

Protein? Chicken, eggs, fish, beef, dairy. Omega-3s? Salmon, sardines, walnuts. Vitamins and minerals? Fruits, vegetables, whole grains.

If your diet covers your needs, many supplements become unnecessary.

What to Look For in Any Supplement

1. Third-party testing. Look for NSF Certified for Sport or Informed Sport certifications.
2. Transparent labels. Every ingredient and dose should be clearly listed. Avoid “proprietary blends.”
3. Minimal fillers. The fewer ingredients, the better.
4. Realistic claims. If it sounds too good to be true, it is.

The Dexter Tenison Fitness Stance

We recommend a small number of evidence-based supplements to our clients — never an entire cabinet full of pills. Build your nutrition foundation first, train consistently, and then consider supplementing the gaps.

That’s the honest approach, and it’s the one that works.
