The supplement guide · Evidence before extras
Vitamins, minerals, creatine, and the space between a useful option and an expensive promise. Understand the purpose, read the label, and decide what deserves a conversation.
A nutrient gap, a diagnosed deficiency and a training goal are different questions. A product being popular does not tell you which one applies.
Bring all your labels and medicines to a pharmacist or clinician. Overlap, interactions and your health history matter more than a “for women” label.

Quality is one question
Independent verification can address label contents and certain quality standards. It does not establish that a supplement is safe for your circumstances, necessary, or effective for the goal advertised.
FDA does not approve dietary supplements for safety and effectiveness before they go on sale. Check the exact product in the certifier’s own directory, rather than relying on a marketplace image.
