For supporting your methylation, cell division, and cardiovascular health, this **Folate** supplement delivers 800mcg — right at the top of the 400-800mcg clinical range. You're getting it as calcium folinate (folinic acid), which is a bioactive form your body can use without the multi-step conversion that synthetic folic acid requires — particularly relevant if you have MTHFR gene variants that impair folic acid processing.

Folinic acid is distinct from methylfolate (5-MTHF), the other popular active folate form. What this means for you: folinic acid enters the folate cycle at a different point, which some practitioners prefer for individuals who are sensitive to methylfolate or need broader folate pathway support.

The one thing to keep in mind: if your primary goal is homocysteine reduction, folate works best alongside vitamins B12 and B6. This product delivers folate alone, so you'd want to ensure you're getting those cofactors from your diet or another supplement.
