Our assessment
The evidence shows that this product contains a specific form of folate, but the available data is primarily for calcium, not for methyl folate. You should be cautious about expecting benefits based on this data, as it does not directly apply to the ingredient in PureFormulas Methyl Folate L-5-MTHF. Data not available for the specific benefits of this ingredient.
How it works
Calcium, which is not the active ingredient in this product, supports bone mineralization and neuromuscular relaxation [NIH ODS]. The mechanism for L-5-MTHF is not provided in the data. Data not available for how this specific ingredient works.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. Based on calcium data, high intakes might increase the risk of heart disease and prostate cancer, and can cause poor muscle tone, constipation, and nausea [NIH ODS] [FDA data]. These side effects are not confirmed for methyl folate.
Our recommendation
Start by consulting your healthcare provider to confirm you need a methyl folate supplement. Do not rely on calcium data to guide your use of this product. Choose this supplement only if directed by a clinician for a specific deficiency or genetic need. Data not available to support general use.
