What We Talk About

• How the supplement industry has evolved from single ingredients to niche, hyper-specific products
• SuppCo's mission to help consumers navigate supplement choices
• SuppCo's "Trust Score", rating brands on 30+ manufacturing attributes
• Third-party lab testing results on popular supplements bought online
• Creatine gummies found to be severely underdosed or missing active ingredient
• Lack of consistent regulatory testing after a product's initial approval sample
• How Amazon's "golden sample" testing loophole allows inconsistent product quality
• Why gummies struggle with heat- and moisture-sensitive ingredients like probiotics
• Dosing limitations of gummies (e.g., needing many gummies for a full creatine or omega-3 dose
• Buying from official brand storefronts vs. third-party Amazon sellers
• How absorption varies by form factor (capsules, powders, liquids, soft gels)
• Why probiotics need enteric-coated capsules to survive stomach acid
• Why fat-soluble nutrients (vitamin D, omega-3) are best delivered in fat-based formats
• Why creatine powder is considered the most stable, effective format
• Risks of stacking too many supplements without understanding interactions
• Downsides of proprietary multivitamin blends with hidden ingredient amounts
• Recommended "non-negotiable" starter stack: creatine, vitamin D3/K2, and magnesium
• The importance of knowing your specific reason for taking any supplement
• Which supplements can be taken indefinitely vs. those that should be cycled (e.g., berberine)
• Common supplement myths debunked (creatine as a gym-only supplement, price equals quality, more supplements equals better health, electrolyte necessity)
• The role of the placebo effect in perceived supplement benefits
• Where supplement regulation is headed and the growing role of consumer awareness
