Cardio B by Ortho Molecular Products

This is for adults with elevated Homocysteine on labs or a family history of early heart disease who want a targeted homocysteine supplement, not a generic multivitamin. It also fits vegans and older adults with low Vitamin B12 or borderline Folate, and people on oral contraceptives or frequent pain relievers who tend to run low on B vitamins. If your homocysteine is normal, you likely do not need this dose.

Homocysteine is a sulfur amino acid your body must recycle. Folate and Vitamin B12 remethylate homocysteine back to methionine (a building-block amino acid), while Vitamin B6 helps convert homocysteine down the detox pathway to cysteine. Betaine (trimethylglycine) donates methyl groups (one-carbon units) as a backup route in the liver. Together, these steps commonly lower homocysteine 20–30% within 4 to 8 weeks if your levels are high at baseline.

Take 1 capsule daily with food, preferably in the morning since B vitamins can feel energizing. Recheck Homocysteine after 4 to 8 weeks to see if you are a responder. If your Vitamin B12 or Folate are low, consider testing Vitamin B12, Methylmalonic Acid (a functional B12 marker), and Folate, RBC, then adjust dosing with your clinician.

This uses high-dose folic acid. People with MTHFR variants sometimes prefer L‑methylfolate; folic acid can still lower homocysteine, but switching forms is reasonable if levels do not budge. Avoid in pregnancy or while trying to conceive unless a clinician recommends this dose. If you have active cancer, take methotrexate for cancer, or recurrent high LDL on betaine, discuss with your doctor first.

Folic acid can reduce side effects of low-dose methotrexate used for autoimmune disease, but high doses should be coordinated with your prescriber. Rarely, betaine can nudge LDL-C up; check a lipid panel (LDL-C or ApoB) after 8 to 12 weeks. Very high chronic B6 can cause nerve symptoms; 50 mg is below typical risk, but report new numbness or tingling.
