Vitamin B6 dosage, intake, recommended daily allowance

The recommended sietary allowance (RDA) is the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97 to 98%) healthy individuals in each life-stage and gender group. The most common supplemental intake is 10–25 mg per day. However, high amounts (100–200 mg per day or even more) may be recommended for certain conditions. The recommended dietary allowance (RDA) for vitamin B6 is 2.0 mg/day for the adult man and 1.6 mg/day for the adult woman. Pregnant women require an additional 0.1 mg per day and those that are lactating require and additional 0.7-0.8 mg daily. Those who use pyridoxine for the management of premenstrual syndrome, typically use doses ranging from 50 to 100 milligrams/day. Those who use pyridoxine for the management of carpal tunnel syndrome, typically use doses ranging from 100 to 200 milligrams/day. Vitamin supplements should always be taken with water, preferably after a meal. Vitamin B6 is available in nutritional supplements principally in the form of pyridoxine hydrochloride. Pyridoxal 5'-phosphate is also available as a nutritional supplement. Pyridoxine hydrochloride is available in multivitamin and multivitamin/multimineral products as well as products that, in addition to vitamins and minerals, contain other nutritional substances. Single ingredient pyridoxine products are also available.
