FAQ

What makes a supplement brand “transparent”?
A “transparent” supplement brand shows you exactly what you’re getting: full ingredient lists with precise doses, no proprietary blends that hide amounts, and clear explanations of why each ingredient is there. Transparent Labs, Legion Athletics, and Naked Nutrition all lean toward this approach, but Transparent Labs emphasizes it as a core part of the brand.
Is Transparent Labs third-party tested?
Transparent Labs markets itself around quality and testing, with an emphasis on clean formulas and clear labeling. Like with any supplement, it’s smart to review the specific product page for testing details, certificates, and quality information — and talk with a healthcare professional if you have medical conditions, take medications, or are unsure what’s right for you.
Are these supplements safe to use every day?
These brands are widely used by athletes and gym-goers, and their products are generally designed for regular use as directed. However, “safe for every day” depends on your health, dose, and the specific product (for example, stimulant pre-workouts vs. plain protein). Always read labels carefully and check with your doctor or a qualified health professional before starting any new supplement routine, especially if you have underlying conditions or take prescription meds.
Which brand should I choose?
Pick Transparent Labs if you want the best overall mix of clear labels, performance-oriented formulas, and a broad product range under one roof. Choose Legion Athletics if you love evidence-based content and want supplements that pair with detailed training and nutrition guidance. Go for Naked Nutrition when you mainly need simple, clean proteins and a few minimalist staples — often alongside other brands.
