Tryptophan is the precursor for vitamin B3 as nicotinamide adenine dinucleotide (NAD). Only about 1/60th of the tryptophan in the body is actually converted to NAD.

Did you know? Enjoy pasta – carbohydrates also increase your serotonin levels, which help you to feel better and manage your appetite.

Tips: Taking tryptophan off the spoon followed by coconut water or juice is a great way to absorb tryptophan, as it has low solubility in water.

Warm water (up to 30°C) will aid solubility; higher temperatures may degrade the product.

Pure amino acid powders may be slightly hygroscopic (retain moisture) and this can result in clumping.
