What is tryptophan?

healthy PIG
Tryptophan is an essential amino acid used to make proteins. Your body can't make it, so you need to get it from your diet. Foods containing tryptophan include animal products such as chicken and fish and plant foods such as nuts or soybeans.
When we eat tryptophan, our body converts part of it into 5-HTP, which is then converted into the neurotransmitter serotonin. The body also converts some tryptophan into nicotinic acid adenine dinucleotide (NAD), which is why tryptophan is also considered a dietary source of niacin.
There are two types of tryptophan: L-tryptophan and D-tryptophan. The only difference between the two types is the orientation of the molecules.
You can get tryptophan through certain foods or supplements in powder form.

L-Arginine Benefits and Side Effects

healthy PIG

Taking L-arginine as a supplement can benefit your heart and muscles, but may cause side effects such as nausea, diarrhea, and bloating.

L-arginine is one of many amino acids that the body needs to function properly. Like other amino acids, L-arginine plays a role in building proteins. The body uses protein to help build muscle and rebuild tissue. It converts this amino acid into the chemical nitric oxide, which helps blood vessels dilate.

Researchers investigated L-arginine's effectiveness in treating high blood pressure and chest pain and improving breathing in COVID-19 patients who required hospitalization.

Read on to learn more about L-arginine’s potential therapeutic benefits and the research behind it.
