This old school body building supplement is amazing for boosting the immune system, so much so that it's now being widely adapted by the mainstream beyond just fitness. 

Endurance athletes and powerlifters alike have used this one for years to fend off illnesses and strengthen joints.

In a randomized controlled trial published by the International Journal of Clinical Pharmacology and Therapeutics, 24 athletes were administered 10g of Glutamine per day for six weeks, to determine whether Glutamine supplementation alters immune function in athletes during heavy resistance training.

The results found that T-cell ratings (White blood cells that help mediate immune health) were extremely different between the groups, indicating a positive correlation that glutamine supplementation may be able to restore immune function and reduce the immunosuppressive effects of heavy-resistance training in athletes.

L-Gluatmine can be taken in a pill or powered form. The most popular protocol is to mix it in a post workout or morning shake. It has virtually no taste when mixed with the proper dosage.
