Description

B-Complex #12 offers a complete vitamin B complex, with added vitamin B-12 and folate. Supplementing with the active forms of the B vitamins is extremely important to everyone, especially individuals who might not be able to convert non-active B vitamins to their active forms in the liver because of compromised liver function, poorly functioning enzymes, digestive disorders, or increasing age.* Vitamin B12 and folate are necessary for normal red blood cell formation, tissue and cellular repair, normal methylation and homocysteine metabolism, and DNA synthesis.* Thorne's B-Complex #12 supplies the active form of vitamin B12 – methylcobalamin – as well as the active form of folate – 5-MTHF. The other bioactive forms of the B vitamins in each capsule ensures you will get the most bioavailable vitamin B complex available.* B-Complex #12 is not derived from yeast. Most of the B vitamins, with the exception of vitamin B12, are not stored in the body; consequently, they must be acquired daily from the diet in order to maintain optimal health.* Vitamin B12 deficiency can be manifest with varying degrees of mental changes, such as confusion and irritability.* Certain prescription medications (for seizures, diabetes, arthritis, and cancer) can cause a deficiency of these important vitamins. The incidence of vitamin B12 and/or folate deficiency is high among the elderly. Pregnant women require an increased amount of folate for proper fetal development.* A woman who has a folate deficiency prior to pregnancy can expect that deficiency to be intensified during pregnancy. B Complex #12 includes eight water-soluble B vitamins: thiamin (vitamin B1); riboflavin/riboflavin 5'-phosphate (vitamin B2); niacinamide (vitamin B3); pantothenic acid (vitamin B5); pyridoxine/pyridoxal 5'-phosphate (vitamin B6); methylcobalamin (vitamin B12); 5-MTHF (folate); and biotin; plus choline. Although each B vitamin is chemically distinct, they often work synergistically in various biochemical functions throughout the body – from cellular energy production, to healthy red blood cell formation, to healthy neurological function.* A nutritional supplement that contains these active cofactors has enhanced bioavailability, ensuring the body gets the nutrients it needs.* This product has been third-party tested and certified to verify what's in the package matches what's on the label and to confirm it contains no unsafe levels of contaminants, such as heavy metals, pesticides, and microorganisms.

Recommended Use

Take 1 capsule one to three times daily or as recommended by your health-care practitioner.

Warnings

ALLERGY WARNING: This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients. PREGNANCY: If pregnant, consult your health-care practitioner before using this product. INTERACTIONS: 5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.
