  • Allergic reaction: Itching or hives, swelling in your face or hands, swelling or tingling in your mouth or throat, chest tightness, trouble breathing

  • Make sure your doctor knows if you are pregnant or breastfeeding, or if you have anemia, vitamin B12 deficiency, or a history of bipolar disorder.
What is l-methylfolate used for?
L-methylfolate is the active form of folate (vitamin B9). It is used as add-on support for major depressive disorder in people on antidepressants who have low folate levels, for schizophrenia with elevated homocysteine involving negative or cognitive symptoms as an add-on to antipsychotics, and for folate deficiency. It supports these treatments and does not replace antidepressant or antipsychotic medication.
Is l-methylfolate the same as folic acid?
No. Folic acid is the synthetic, inactive form of vitamin B9 that your body has to convert before it can use it. L-methylfolate is already the active form, so it can be used directly. This is especially relevant for people with MTHFR gene variants, who convert folic acid poorly.
How is l-methylfolate (Deplin) different from a regular folate supplement?
Deplin and similar prescription products supply l-methylfolate, the active form of folate, and are regulated by the FDA as prescription medical foods for managing suboptimal folate levels under a clinician's direction. A typical over-the-counter folate supplement is often plain folic acid, the inactive form, at lower strengths. Ask your provider which product fits your needs.
Does l-methylfolate need a prescription?
Prescription l-methylfolate products such as Deplin, L-Methylfolate Forte, and EnLyte are dispensed by prescription and regulated as prescription medical foods. Talk with your provider about whether the prescription form is right for you, then compare pharmacy prices on Rx.com.

The price of L-Methylfolate without insurance varies by pharmacy, dosage, and quantity. Rx.com compares cash prices at more than 60,000 US pharmacies so you can find the lowest price near you.

What is l-methylfolate and how does it work?

L-methylfolate (also called levomefolate calcium or L-methylfolate calcium) is the biologically active form of folate, the natural vitamin B9. Unlike ordinary folic acid, which the body has to convert through several steps before it can be used, l-methylfolate is already in the form your body and brain can use directly. The FDA regulates it as a prescription medical food for the clinical dietary management of people with suboptimal folate levels, rather than as a conventional approved drug.

It is used as adjunctive (add-on) support for major depressive disorder in people taking antidepressants who have low serum, red-blood-cell, or central-nervous-system folate, and for schizophrenia with elevated homocysteine involving negative symptoms or cognitive impairment as an add-on to antipsychotics. It is also used for folate deficiency. Importantly, l-methylfolate is not itself an antidepressant or antipsychotic and does not replace those medicines.

L-methylfolate cost and coupons without insurance

Because l-methylfolate is sold in lower-cost non-branded versions, its cash price is usually on the lower end, but prices are not fixed. Two pharmacies across town from each other can charge very different amounts for the exact same prescription, which is why comparing before you fill matters. Rx.com checks the current cash price at more than 60,000 pharmacies so you can see where it costs the least near you and print or text yourself a free coupon.

Enter your ZIP above to see today's price at pharmacies near you. The maker of the brand Deplin also runs a manufacturer savings program on its official site, deplin.com; eligibility and terms vary and manufacturer offers typically exclude government insurance, so check the details there. An Rx.com discount coupon is a cash-price option you can use whether or not you have insurance, and you simply use whichever price is lower at the counter.

L-methylfolate vs. folic acid and related products

The biggest difference between l-methylfolate and a standard folate supplement is the form. Folic acid is the synthetic, inactive form that the body must convert; l-methylfolate is already active. This matters most for people with common MTHFR gene variants, whose bodies convert folic acid poorly, and it is a key reason a provider might prescribe the active form.

L-methylfolate is sold as non-branded products and under several brands. Related products include Deplin, the higher-strength L-Methylfolate Forte, and combination products such as EnLyte. These can differ in strength and in added ingredients, so they are not always interchangeable. Ask your prescriber or pharmacist which product matches your prescription, then compare the cash price of that specific product above.

Safety and what to tell your provider

L-methylfolate has no boxed warning and is generally very well tolerated. The most important caution is that folate can mask an underlying vitamin B12 deficiency, correcting the anemia while nerve damage quietly continues, so your provider should check your B12 status. Some products, including the original Deplin, contain algal oil (Schizochytrium), so use caution if you have a fish or algae allergy; note that the reformulated Deplin FC ("Free & Clear") is made without algal oil and is free of major allergens including fish and shellfish. Rare allergic reactions can occur, and occasional irritability, trouble sleeping, or stomach upset have been reported, usually at higher doses.
