Start with these principles
- Food, sleep, and training come first
- Look for credible independent testing
- Check medication and health interactions
Read past the front label
Check the serving size, full ingredient list, amounts, allergens, warnings, and proprietary blends. A long list of compounds does not mean the product has been studied as a combination.
Match evidence to the actual product
Research on one ingredient, dose, or population may not support a different formula or a sweeping claim. Be cautious with before-and-after marketing and promises that sound like drug effects.
Ask a pharmacist when interactions matter
Supplements can affect medications, tests, surgery, pregnancy, and existing conditions. Share the exact product and dose with a pharmacist or clinician rather than asking about a broad category.
Safety and individual needs
Adapt exercise to symptoms, health history, and current capacity. Stop for chest pain, faintness, or unusual shortness of breath. Seek qualified help when pain, recent injury, surgery, pregnancy, or a medical condition changes what is appropriate.
