Basic B Complex

Thorne’s Basic B Complex formula contains the active forms of the B vitamins, making it easy for your body to absorb them.

8 easily-absorbed B vitamins, plus Choline – packed into one capsule for a simple way to promote neurological function and cellular energy production.*

This comprehensive blend provides multiple benefits to support your lifestyle, such as helping convert food into fuel and enhancing cellular energy.*

Because most B vitamins don’t remain in the body, they must be acquired from diet and supplementation to help maintain optimal health.*

Benefits of Thorne's Basic B Complex:

  • Promotes cellular energy production*
  • Supports an optimally functioning nervous system and healthy nerve cells*
  • B vitamins promote the conversion of carbohydrates into energy and the metabolism of fats and proteins*
  • Promotes healthy red blood cell formation*
  • Isn’t derived from yeast, unlike many B vitamin supplements on the market

Supplementing with tissue-ready B vitamins is important for everyone, especially individuals who aren’t able to convert the non-active B vitamins to their active forms.* Factors that can inhibit the body's ability to convert non-active vitamins to their active forms include genetic predisposition, compromised liver function, poorly functioning enzymes, digestive disturbances, and aging.

How to Use

Take 1 capsule one to three times daily or as recommended by your health professional.

Thorne Basic B Complex

What is Basic B Complex?

Basic B Complex contains an optimal balance of the entire B complex plus choline – 10 water-soluble compounds. Basic B Complex contains thiamine (vitamin B1), riboflavin 5’-phosphate (active vitamin B2), niacin and niacinamide (two forms of vitamin B3), pantothenic acid (vitamin B5), pyridoxal 5’-phosphate (active vitamin B6), methylcobalamin (active vitamin B12), 5-MTHF (active folate), biotin, and choline. Unlike many B vitamin supplements on the market, Thorne’s Basic B Complex is not derived from yeast.

What does Basic B Complex Do?

Basic B Complex contains active forms of B vitamins for enhanced availability to the tissues.* B vitamins are essential for healthy nerve cell function, neurotransmitter formation, red blood cell formation, healthy adrenal function, energy production, healthy methylation, cardiovascular health, and more.*

Why take a B Complex nutritional supplement?

B vitamins are water-soluble and most do not remain stored in the body, so they must be acquired daily from the diet or from supplementation in order to help maintain optimal health.*

Why include active, tissue-ready forms of some of the B vitamins?

Some B vitamins require conversion in the liver to their active forms, ready to be used by the body. Among the factors that can inhibit the body’s ability to convert non-active vitamins to their active forms in the liver are compromised liver function, poorly functioning enzymes, digestive disturbances, and age. Thorne’s Basic B Complex contains the entire B complex, including the activated forms of vitamin B2 (riboflavin 5’-phosphate), vitamin B6 (pyridoxal 5’-phosphate), folic acid (L-5-methyltetrahydrofolate), and vitamin B12 (methylcobalamin).



This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients.


If pregnant, consult your health professional before using this product.


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.
