B-Complex #6 by Thorne

If you’re searching for a vitamin B6 complex because your Homocysteine is high, your energy is flat, or you’re on meds that deplete B6, this fits. The extra B6 (100 mg) helps if you use oral contraceptives or isoniazid (both lower B6), and the methylfolate plus methylcobalamin form suits those with MTHFR variants. It’s also a practical B-complex for athletes (NSF Certified for Sport) and for vegans whose Vitamin B12 runs low or borderline.

B vitamins are coenzymes, the helpers your enzymes need to turn food into energy. Thiamin, riboflavin, niacinamide, and pantothenate drive carbohydrate and fat metabolism, which you’ll see as steadier energy rather than a stimulant buzz. Vitamin B6 supports neurotransmitter making (serotonin and GABA, the calming signal) and converts homocysteine into cysteine. Methylfolate and methylcobalamin run methylation, the one‑carbon tagging system that builds red blood cells and lowers Homocysteine. Biotin supports carboxylase enzymes, and choline feeds acetylcholine, a memory signal.

Take one capsule with breakfast. Niacinamide is the non‑flushing form of niacin, so you shouldn’t feel a hot flush. Morning is preferred because B vitamins can feel activating if taken late. If you’re repleting low status (Homocysteine high, Vitamin B12 or Folate low), expect 4 to 8 weeks for labs to improve. For long‑term maintenance once levels normalize, you can stay daily or use it 5 days per week.

Chronic high vitamin B6 can cause nerve tingling or numbness, so avoid stacking this with other B6-heavy products. Skip or use only with clinician guidance if you’re pregnant, on levodopa without carbidopa (B6 reduces its effect), under active cancer or psoriasis treatment using methotrexate without folate rescue, or if you’ve had unexplained neuropathy. If your Vitamin B12 is very low (or Methylmalonic Acid is high), treat B12 first to avoid masking anemia.

Energy changes tend to be subtle and steadier rather than a jolt, showing up within 1 to 2 weeks. Homocysteine usually moves in 4 to 8 weeks when B status was low. If you’re using it for mood or PMS symptoms tied to low B6, evaluate after two cycles. If you feel tingling, vivid dreams, or nausea, take with food and consider cutting frequency, then recheck labs.
