L-Methylfolate 1mg by MethylPro

A 1 mg capsule sits between an everyday folate and the high-dose products a clinician directs. It fits adults whose RBC Folate has tested low, whose Homocysteine stays raised on a lower dose, or whose MTHFR Genotype shows a variant and whose clinician wants more than a multivitamin supplies. It is more than most people with a good diet and normal labs need. If that describes you, a lower-strength folate, or none, is the better choice.

L-methylfolate (L-5-methyltetrahydrofolate, or 5-MTHF) is the form of folate that circulates in blood. Folic acid and food folate must be converted to it in several steps, the last of which depends on the MTHFR enzyme; supplying it ready-made skips that step. In cells it hands a methyl group to homocysteine to regenerate methionine, a reaction that needs vitamin B12, and it supports the making of DNA and red blood cells. The label lists the calcium salt, plus 270 mg of glycine, an amino acid for which it makes no claim.

Each capsule provides 1.7 mg DFE of folate, which is 1 mg of L-5-methylfolate. The label's suggested use is 1 capsule daily, or as directed by a healthcare practitioner. It can be taken with or without food. Morning is a sensible default, since some people find methylfolate mildly activating. There is no benefit in doubling up on days you feel tired; folate works over weeks, not hours.

Check Vitamin B12 before you start. Folate at this dose can normalize the blood count in B12 deficiency while nerve damage goes on, so a low or borderline Vitamin B12, or a raised Methylmalonic Acid, needs attention first; many clinicians give the two vitamins together. Tell your prescriber if you take methotrexate, or an anti-seizure medicine such as phenytoin, phenobarbital or primidone, because folate can interfere with them. If you are pregnant or nursing, or have a seizure disorder, ask your clinician before taking it.

Recheck Homocysteine after 4–6 weeks and RBC Folate after 8–12 weeks, then settle on the lowest dose that keeps both in range. Most people feel no different. A minority notice irritability, restlessness or poor sleep, which is a sign to step down to a lower strength. Compared with folic acid, methylfolate costs more but does not rely on the conversion step. L-methylfolate is sold in several strengths, so the dose can be matched to your labs.
