The Natural Serotonin Blockers. Now you may ask why would someone want to block or antagonize serotonin? Well...some people naturally have a little too much, to the point where it causes autonomic dysfunction.... or perhaps you are trying to augment the effects or reduce the effects of an SSRI anti-depressant? In which case the following may be helpful.
It is shown that "Panax Ginseng" is a potent serotonin antagonist. It blocks human serotonin 5-HT(3) receptors and thus stops nausea in it's tracks(1)(2)(3). It also directly decreases serotonin in the hypothalamus and inhibits exercise induced increases in serotonin(4)(5).
Ginseng also acts as a noncompetitive nicotinic receptor antagonist and also inhibits Calcium Channels and Sodium Channels(6)(7).
You can buy a super potent red panax ginseng extract below, guaranteed serotonin antagonist.
PRODUCT ONE
The next Natural serotonin antagonist is called "Shilajit".
Shilajit was found to decrease both total and neuronal serotonin levels, especially in the hypothalamus.

It also blocks the enzyme "AcHe" which helps sustain elevated Acetylcholine levels; which in turn lowers serotonin production!
Shilajit is thus a very potent Pro-Cognitive supplement that also lowers serotonin.
Recommended Shilajit Product is below!
The THIRD Natural OTC Serotonin Antagonist would be something called "Vitex Agnus Castus" extract, and this mechanism probably accounts for a great deal of why it also strongly inhibits prolactin levels in both men and women(8)(9)(10)
However, Vitex also exerts significant progestogenic activity, and I don't recommend this product for men necessarily.
And the FOURTH natty serotonin antagonist is one that is often heard about.
Yohimbe Bark Extract
Be careful as the product can be VERY stimulating.
