Buying Guide

Choose the right folate form

Select L‑methylfolate if you need the bioactive form or folic acid if you prefer the synthetic, widely used form

Check microgram or milligram strength

Match label strength to your health goal or clinician recommendation, noting some products list mcg and others mg

Consider cofactor nutrients

Look for supplements with B12 or B6 if you want combined support for methylation and homocysteine metabolism

Look for dietary suitability

Pick vegetarian or vegan capsules and verify non‑GMO or gluten‑free tags if you have dietary restrictions

Evaluate servings per container

Compare capsule/tablet counts to understand monthly cost and how long a bottle will last at your dose
