    Product Overview


    • Dietary Supplement

    Comprehensive B Complex Support

    • Unlike Many B Vitamin Products, Basic B Complex Contains the Active Forms for Enhanced Bioavailability
    • Basic B Complex Contains an Optimal Balance of Essential B Vitamins
    • Basic B Complex is Yeast Free

    Basic B Complex consists of a group of eight water-soluble compounds: thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), cobalamin (vitamin B12), folate, and biotin. Although each B vitamin is chemically distinct, they often work together in various biochemical functions throughout the body – from cellular energy production, to healthy red-blood-cell formation, to healthy neurological function. Most 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.

    Supplementing with active B vitamins is extremely important to everyone, especially individuals who may not be able to convert non-active vitamins to their active forms in the liver because of compromised liver function, poorly functioning enzymes, digestive disturbances, or age. Dietary supplements containing these active cofactors have enhanced bioavailability, ensuring the body gets the nutrients it needs.

    Thorne Research'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), as well as 80 mg choline citrate. Although choline is often grouped with the B vitamin family, it is not officially a B vitamin.

    Suggested Use

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

    Other Ingredients

    Hypromellose (derived from cellulose) capsule, microcrystalline cellulose, silicon dioxide, magnesium laurate, magnesium citrate.


    Tamper Evident: Use only if bottle is sealed. Store tightly sealed in a cool, dry place.

    If pregnant, consult your health-care practitioner before using this product.

    Improved hair

    Posted by iHerb Customer on Jan 12, 2018 | Verified Purchase

    My hair is in better condition less shedding. I feel so much better overall. Does not cause any stomach upset for me.

    Thanks for your feedback!

    Great product with all possible vitamins in active forms!

    Posted by iHerb Customer on Jan 11, 2018 | Verified Purchase

    Great b-complex product, especially for people with MTHFR mutations. Huge doses, not too huge pills easy to swallow. What I like the most about this product is that it contains only methylated forms of vitamins, not 50%/50% or anything like that. I'm definitely going to purchase this product again, the best b-vitamins available on the market.

    Thanks for your feedback!

    Great supplement for MTHFR

    Posted by iHerb Customer on Jan 07, 2018 | Verified Purchase

    This is a great supplement for me as I am triple compound MTHFR genetic variants. I can't take other B vitamin supplements that are typically the wrong form of B vitamins that my body can't break down or convert into the bio-available forms. Like many other people with genetic variants from MTHFR, I can't use cyanocobalamin, or pyrodoxine or folic acid. The form of B vitamins in Thorne Basic B Complex has no bad side effects for me at all. I don't want to be without it. I take 1 capsule daily. Great product.

    Thanks for your feedback!

    Great B Complex

    Posted by iHerb Customer on Dec 14, 2017 | Verified Purchase

    Love that it has many of the active forms and some choline. Plus fillers are non-allergenic which I find important. All of Thorne Research's B complexes are probably equally great in general, but for me personally I like this one due to there being a fairly low amount of riboflavin compared to their others which for me tends to aggravate my autoimmune issues.

    Thanks for your feedback!

    Very good! Great product. My hair has improved considerably. I'm taking them preventively.
