What to Look for (and Avoid) When Buying Supplements

Looking for safe, effective supplements that actually work?
With thousands of products on the market, choosing the right vitamins or performance supplements can be overwhelming—and costly if you get it wrong. This guide will show you what to look for and what to avoid when buying supplements, so you can make smart, science-based decisions for your health.

Why Supplement Quality Matters

Not all supplements are created equal. In fact, many over-the-counter options contain low-quality ingredients, hidden fillers, or misleading labels. Choosing the right supplements isn’t just about results—it’s about protecting your health.

At Redefine Fitness, we’ve helped hundreds of clients optimize their wellness by recommending only professional-grade supplements backed by science.

✅ What to Look for When Buying Supplements

1. Third-Party Testing

Always choose supplements that are independently tested for purity and potency. Third-party certification ensures that the product contains exactly what it says—no more, no less.

2. Clinically Effective Dosages

Some supplements list effective ingredients but in quantities too low to make a difference. Look for products with clinically studied dosages, not marketing gimmicks or “proprietary blends” that hide the truth.

3. High Bioavailability

It’s not just what you take—it’s what your body absorbs. Look for highly bioavailable forms of nutrients, like:

Magnesium glycinate (vs. magnesium oxide)
Methylated B-vitamins (like methylcobalamin or methylfolate)
Curcumin with black pepper extract (for absorption)

4. Clean Ingredients & Transparency

Choose supplements with no artificial colors, preservatives, or sweeteners. Read labels carefully—if it’s full of words you can’t pronounce, it’s probably not ideal.

❌ What to Avoid in Supplements

Proprietary blends with hidden ingredient amounts
Too-good-to-be-true claims like “burn fat fast” or “boost testosterone overnight”
Unclear sourcing or manufacturing practices
Ultra-cheap pricing (usually = ultra-low quality)

If a supplement brand isn’t open about where and how it’s made, skip it.
