This very powerful B vitamin combination formula supplies most of the B vitamins in their coenzymated forms so the body does not have to phosphorylate them in order to be used in biochemical reactions. This formula also includes a proprietary NatureFolate™ blend of active isomer naturally-occurring folates. TMG and choline are included to support methylation.*
B Vitamin Contraindications
Niacin and Niacinamide: Avoid both of these forms in high doses if you have jaundice, heart conditions including angina and rheumatic heart disease, ulcers, gastritis, renal failure, or gout.
Vitamin B6: Do not take B6 with the drug levodopa, as it can inactivate it. Lactating women should not take more than 50 mg of B6 per day, as higher doses may suppress lactation.
Folate: Avoid folate (and folic acid supplements) when taking the drug methotrexate.
