Arginine, an amino acid, increases HGH. Studies indicate that you need about 15-20 grams per day. That is quite a bit, so choose foods carefully. Turkey breast is the highest in arginine, at 16 grams per breast.
Other foods high in arginine include pork loin, chicken, pumpkin seeds, soybeans, and peanuts. In order not to gain too much weight, you may need to supplement your arginine rich foods with a supplement.
If you want to grow, you need protein. The amino acids in protein are used by your body to create all the tissues from organs to bones. Beef has been shown to help you synthesize L-orthinine, an amino acid that plays a role in healthy cells.
Eat grass-fed beef, coconut meat, pasture raised chicken and omega 3 enriched eggs.
Plant based proteins are as healthy as meat proteins, so don’t worry that your teen vegetarian will necessarily be short.
