I do a lot of psychopharmacology research – more than most people would consider normal. I only try to share the most interesting and related findings while making you the most technical details. But today, you are for a deeper dive.
This issue is very important to ignore, especially if you are struggling with treatment -resistant depression.
What is L-methyllic (MTHF)?
L-methylopholic (MTHF) is the biologically active form of folic acid, a vitamin B vitamin for brain function and the production of neurotransmitters. Your body converts the nutritional folic to MTHF, but this process requires specific enzymes – and does not produce everyone effective enough.
You have probably heard of folic acid, the synthetic version of the folicate usually found in supplements and prenatal vitamins. While folic acid can increase MTHF levels, the conversion process is not always effective, especially for people with certain genetic variants.
Why the L-methyl material for mental health?
The low levels of MTHF are associated with depression and some people do not compose enough of it, even with a leafy -rich diet or supplements. This is where things get interesting:
- MTHF is essential for the production of serotonin, dopamine and norepinephrineBrain chemicals target most antidepressants.
- Some studies show that MTHF can enhance the efficacy of antidepressants, even in people without deficiency.
- Some medicines, including anticonvulsions (mood stabilizers such as Lamotrigine [Lamictal]) can be able to run out of MTHF levelsPossibly decrease in the effectiveness of antidepressants over time.
Can L-methylofolic help when antidepressants do not work?
Emerging surveys show this Fill in L-methylaphic can improve antidepressant response (see below) to people with depression. Unlike standard antidepressants, which directly affect neurotransmitters, the MTHF works by supporting their natural production. (Note: The following study indicates that it can work even better for those with inflammation or higher body mass index [BMI]Obesity.) L-methyllic has also been shown to help those with treatment resistant to treatment.
THE The Food and Drug Administration (FDA) regulates L-methyllic as medical foodwhich means that it requires a prescription but is not classified as a medicine. This means that it is unlikely to contribute to the load of your side effects.
My experience with L-methylophole
My doctor-who is about non-nonsense as they come-introduced me to the L-methlephole. He respects the researchers who studied it and thought it was worth trying. Since I have been in anticonvulsants for years (eight, to be precise), it is not shocking that I could be low in essential nutrients.
Could this explain why antidepressants sometimes stop working? Could MTHF be the missing piece for some people? Probably.
Final Thoughts: Should you try L-methyllic?
L-methylopholic is not a miraculous treatment and research is still evolving. But if antidepressants do not work – or if they have stopped working – it may be worth discussing with your doctor. Since it is relatively low risk compared to other psychiatric therapies, it could be an option worth exploring.
As always, Don’t start any new supplement without medical supervisionEspecially if you are in other medicines.
Recent L-Metylopholic research
Here are some recent studies showing that L-methlephole can benefit those who receive antidepressant for depression:
