Information, not medical advice
Everything on Pure Nutrition Facts, including articles, nutrition tables, supplement reviews, recipes and calculators, is for general information and education only. It isn’t medical advice, diagnosis or treatment, and it isn’t a substitute for advice from a doctor, pharmacist, registered dietitian or other qualified health professional.
Always speak to a qualified professional before you change your diet, start or stop a supplement, or make a decision about a health condition, especially if you:
- are pregnant, trying to get pregnant or breastfeeding
- take any prescription or over-the-counter medicine
- have a medical condition or are having surgery
- are choosing food or supplements for a child
Never stop or change prescribed medication because of something you read here, and never delay getting medical help.
