These L-Tryptophan 500 mg 120 Capsules from Source Naturals may help you if you’re having trouble sleeping.

The essential amino acid L-Tryptophan is not produced in the body and must be sourced from a balanced diet. This amino acid is usually found in protein rich foods like red meat‚ yogurt‚ fish‚ milk and more. However‚ modern‚ erratic lifestyles may wreak havoc on our diet‚ which is‚ more often than not‚ incomplete and imbalanced. That’s why this dietary supplement from Source Naturals may be so beneficial‚ it may possibly go a long way in supporting your body’s need for L-Tryptophan.

L-Tryptophan may play an essential part in the synthesis of melatonin as well as serotonin hormones. These hormones can inform our response to stress‚ sleep‚ waking cycles‚ and our mood.

L-Tryptophan 500 mg from Source Naturals‚ when taken regularly‚ may improve certain symptoms of low mood by increasing the production of serotonin in our brains.

Source Naturals’ L-Tryptophan 500 mg may also potentially support your body’s immune function. Some studies state that L-Tryptophan is the precursor to kynurenines‚ which is essential for the regulation of your immune health.

These L-Tryptophan 500 mg 120 capsules from Source Naturals are free of yeast‚ dairy‚ soy‚ egg‚ gluten‚ wheat‚ starch‚ salt‚ preservatives‚ artificial color‚ flavor and fragrances.
