In these troubled times, such supplements are especially relevant, but few people know truly effective stress-relieving remedies. Usually, the choice boils down to alcohol or valerian tincture.
I'll offer two highly effective supplements you haven't heard of yet:
L-Theanine is an amino acid found in tea. It has a relaxing effect without causing sedation. It's effective at relieving tension or anxiety, but for a noticeable effect, you need to take at least 200 mg at a time.
You can buy it on iHerb, but it's best to look for options that contain the patented L-Theanine brand— Santeanine® .
Phenibut is an old drug developed during the Soviet era, but it is very effective at suppressing excess emotions and anxiety. Phenibut also stimulates thought processes quite well in this context. I've personally verified this 
. These properties are ideal for military personnel and those who need to maintain a cool head in any situation. The effective dose is 500 mg per day.
It is only available in the CIS and Hungary. The West disapproves of this drug and even considers it seditious, which, in my humble opinion, is undeserved.
