Active B-Complex by Integrative Therapeutics

If your Homocysteine runs high or your Vitamin B12 or Folate markers are low, a methylated B complex is a practical fix. It’s also a fit for vegans and vegetarians, people on metformin or acid-suppressing drugs (both can lower B12), and heavy alcohol users. If fatigue, brain fog, or low mood track with a low-normal B12 or Folate, active forms often work better than standard folic acid and cyanocobalamin. This dose is repletion-leaning; long-term daily use is usually 1 capsule, not 2.

Methylfolate and methylcobalamin are the ready-to-use forms of folate and B12. They help recycle homocysteine (a byproduct that stresses blood vessels) back into methionine, which your body uses to add methyl groups (a simple chemical tag) that regulate DNA, neurotransmitters, and energy metabolism. Riboflavin and niacinamide feed mitochondrial enzymes that turn food into ATP, while P5P, the active B6, helps make serotonin and GABA, the brain’s calming signal. These changes show up on Homocysteine and Methylmalonic Acid within 4–8 weeks.

Take 1 capsule with breakfast. If your Homocysteine is high or your Methylmalonic Acid suggests low B12, use 2 capsules for 4 to 8 weeks, then retest and step down. Morning is best to avoid late-day alertness. It’s fine with or without food, but food reduces mild nausea. Expect bright yellow urine from riboflavin—that’s normal, not dehydration.

If you take methotrexate for cancer or autoimmune disease, ask your clinician before any folate; it can interfere with treatment plans. Levodopa without carbidopa can be inactivated by vitamin B6, so avoid this B complex in that scenario. Long-term high B6 can cause neuropathy; if you use 2 capsules (100 mg B6/day), keep it short and monitor symptoms. Pregnancy is better served by a prenatal with iodine, iron, and choline targets.
