5-HTP is best known for its powerful effects in promoting better moods, a calmer affect, better sleep, less “brain chatter” and chronic worrying, and fewer sugar cravings. At higher doses, it can even be effective in reducing chronic pain, such as the widespread pain associated with fibromyalgia.

5-HTP (also known as 5-hydroxytryptophan) is produced from the amino acid L-tryptophan. We naturally get amino acids like L-tryptophan, and subsequently 5-HTP, when we consume adequate protein in our diets. However, some people end up deficient in 5-HTP, especially if they consume a low-calorie or low-protein diet, or eat a significant amount processed foods and sugar.

5-HTP readily crosses the blood-brain barrier, and is effective for increasing serotonin levels in the brain. Serotonin is often touted as the “feel good” neurotransmitter due to its positive effects on mood. By enhancing the levels of serotonin in the brain, 5-HTP can help support mood, relaxation, neural tissue, and sleep quality. 5-HTP (at higher doses) may be useful for supporting sleep quality since some of it will be converted to melatonin. Furthermore, there is some data that suggests 5-HTP supplementation supports weight loss by reducing cravings and food intake.

Nutritional Weight & Wellness® Nutritionists recommend: 1-2 capsules, 10-15 minutes before each meal for even moods, less anxiety, and reduced sugar cravings. 2-6 capsules at bedtime to encourage sleep or reduce chronic pain.
