Deplin® is a prescription medication designed to be taken alongside antidepressants. It works by improving the brain’s ability to make serotonin, norepinephrine, and dopamine, which enhances the effects of antidepressant medication.
Deplin® is classified as a “medical food” rather than a drug. Medical foods are products that are specially formulated to manage conditions with specific nutritional needs and cannot be fulfilled by diet alone.
Deplin® contains a form of folate that has already been converted to its bioactive form, L-methylfolate, which allows it to be immediately absorbed by the body. Deplin® is available in 7.5 mg and 15 mg dosages.
What is Deplin® Used For?
Deplin® medication is used to treat people who have depression, schizophrenia, or hyperhomocysteinemia due to folate deficiency.
Folate is required for the synthesis of neurotransmitters such as serotonin, norepinephrine, and dopamine. Low levels of these chemicals are implicated in major depression and other psychiatric disorders, which is why folate deficiency is linked with depression. As the active form of folate, L-methylfolate can pass through the “blood-brain barrier” and enter the central nervous system, where it can increase levels of these neurotransmitters.
For people with an MTHFR mutation (around half the world's population), dietary folate or folic acid supplements will be ineffective because their body cannot convert it into active folate. This is why L-methylfolate supplements may help those with mood disorders.
Research has shown that taking L-methylfolate with an antidepressant is more effective in improving depressive symptoms and function than taking an antidepressant alone. The antidepressant therapy was also better tolerated along with the L-methylfolate 1.
Other studies have shown that patients managed with L-methylfolate achieved statistically significant improvements in their self-reported depression symptoms and functioning as well as greater satisfaction with their medication treatment 2.
Deplin® side effects
Deplin® is generally reported to be safe and well-tolerated 3.
Some people have reported allergic reactions to L-methylfolate calcium. Consult your health professional if you have a skin rash, itching, swelling of the face, or hives.
Agitation, anxiety, and gastrointestinal issues have also been reported.
Deplin® dosage
The standard adult dosage is one Deplin® 7.5mg capsule twice a day. Deplin® can be taken with or without food.
When not to take Deplin®
If you are allergic to Levomefolate, folic acid, other medicines, dyes, preservatives, milk or soy, talk to your health professional before taking Deplin®. You should also tell your health professional if you are deficient in B12, have a low red blood cell count, or if you are pregnant, breastfeeding, or trying to conceive.
How to take Deplin®
Deplin® should be swallowed whole with water. It can be taken with or without food.
If you miss a dose, take it as soon as you can. But if it’s nearly time for your next dose, skip the missed dose to avoid doubling up or overdosing

Frequently Asked Questions about Deplin®
What does the drug Deplin® do?
Deplin® contains a high dose of L-methylfolate, the bioavailable form of vitamin B9. L-methylfolate is essential for supporting healthy mood, DNA production, cognitive function, and much more. Methylfolate helps the brain to produce serotonin, dopamine, and norepinephrine. These neurotransmitters play an important role in mood management. Low levels of neurotransmitters have been associated with mental health disorders such as depression, schizophrenia, and bipolar disorder 4.
Many people who are diagnosed with depression will be prescribed antidepressants. Antidepressants are prescription drugs designed to enhance the availability of neurotransmitters such as serotonin in the brain, which can reduce symptoms of depression. However, people who already have low levels of these neurotransmitters are less likely to benefit from antidepressants such as selective serotonin reuptake inhibitors (SSRIs).
By increasing neurotransmitter levels, L-methylfolate improves the effectiveness of antidepressant medication and the symptoms of depression in patients who are otherwise treatment-resistant 5.
Why is Deplin® so expensive?
Deplin® requires a doctor’s prescription, which can make it unaffordable for those who don't have health insurance. Many insurance companies don’t cover this medical food and it can be quite expensive. Talk to
your medical professional to determine if Deplin® would be a good addition to your health needs.
A Deplin® generic formulation is available over-the-counter from Methyl-Life®. These L-methylfolate calcium supplements are chemically identical to Deplin®, and include dosages of 15mg, 7.5mg, 5mg, and 2.5mg.
Is Deplin® a controlled substance?
Deplin® is classed as a vitamin or “medical food”, and it is not a controlled substance. It has not been classified as a risk during pregnancy, however it is recommended that you consult with your doctor before taking Deplin® during pregnancy.
Can you buy Deplin® over the counter?
Deplin® can only be prescribed by a healthcare professional, so it cannot be purchased over the counter. It should only be used under the direction of a physician.
Is Deplin® covered by insurance?
Every insurance plan is different, but most will not cover Deplin®. Check with your insurance provider for specific details regarding drug coverage and copayment.
