I've seen this question pop up a few times "why does folate make me worse?" I've found this simple explanation:
Epigenetics is essentially the study of how external factors (like nutrition, stress, oxidative damage, etc…) influence the way our genes express themselves. Folate and folic acid, according to the Walsh Research Institute, have an epigenetic effect on the SERT transporter. The SERT transporter helps to reuptake serotonin after it’s been released. SERT is the target for many pharmaceutical antidepressants (SSRIs, or Selective Serotonin Reuptake Inhibitors). SSRIs work because they interfere with SERT and so serotonin stays active longer, which means you get more benefit from this happy neurotransmitter. Methylfoate, folate from foods and folic acid, while they increases serotonin production through BH4, also increase SERT via an epigenetic effect. This means they help your brain to clear out serotonin faster, thereby reducing the amount of serotonin that is available for you to use. Essentially this makes folate the anti-anti-depressant. Sigh.
