Because we are not licensed medical health professionals, the Seeking Health team cannot recommend a dosage of a product by age group. Dr Lynch, though a health professional himself, believes that dosing can depend on existing conditions, lifestyle, weight, activity level, diet and much more, making dosing difficult. Technically, the FDA considers adults to be ages 4 years of age and older when it comes to nutrient requirements. Seeking Health recognizes that the dietary needs of a young child will be much different than that of a full-grown adult. Therefore, we have provided credible resources below from the National Institute of Health and Linus Pauling Institute that can help you decide the best dosing for your patient (of any age).
