Supplements are not regulated with the same rigor as medications. Quality, actual dosage, and ingredient purity vary widely by brand. Dosage ranges in this guide are educational references based on commonly studied amounts — your personal dose depends on age, weight, kidney function, existing conditions, and medications. Work with a doctor or registered dietitian for guidance personalised to you.
