HelloPharmacist Scorecard of L-Methylfolate 1 mg by MethylPro

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • “Folate” is listed as a grouped ingredient — the label gives one combined amount (1.70 mg DFE) without saying how much of each component you get.

This capsule contains two active ingredients: glycine and folate (in L-methylfolate form, a type of B vitamin). The product also includes cellulose as an inactive ingredient.

Glycine is an amino acid, and folate is a B vitamin your body uses for cell division and DNA synthesis.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Glycine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Glycine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Schizophrenia — rated "Possibly Effective" (Natural Medicines).

Glycine is rated possibly effective for schizophrenia based on available evidence. For other uses listed in the product facts—3-phosphoglycerate dehydrogenase deficiency, ADHD, benign prostatic hyperplasia, and cystic fibrosis—the evidence we hold is insufficient to rate.

We have no effectiveness rating on file for the folate component of this product.

The evidence, ingredient by ingredient Glycine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Glycine is generally well tolerated at typical doses, though long-term safety data are limited. Mild sedation has occurred rarely and resolves quickly if you stop taking it.

Other rare reported side effects include irritability, insomnia, fatigue, memory impairment, headache, soft stools, nausea, vomiting, upper GI discomfort, and dry mouth—though for some of these, any link to glycine is unclear. Not enough reliable safety data exist for glycine in pregnancy or while breastfeeding, so the safety data advises against use unless your doctor approves.

We have no pregnancy or breastfeeding safety information on file for the folate in this product.

Side effects, ingredient by ingredient Glycine

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Glycine.
  • The most serious interaction on file is rated Moderate.
  • For scale: 1 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take clozapine (Clozaril), an antipsychotic, do not start this product without talking to your doctor first—glycine may make it less effective. For any other medications you're on, use the interaction checker below to see what we have on file; we could not check the folate component for interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

MethylPro L-Methylfolate is worth considering if you're looking to supplement folate and glycine, though evidence for glycine's benefit outside schizophrenia treatment is limited. If you take clozapine for schizophrenia, you should not add this product without talking to your doctor first—the interaction suggests it could reduce how well your medication works.

Before starting, check your exact medications with the tool on this page and confirm with your pharmacist or doctor.
