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.

Below are some of the most relevant research-backed benefits derived from 5-HTP use:

  • Supports relaxation, calmness, and mood
  • Stimulates deeper sleep
  • May support weight loss (in higher doses)
  • Supports neural tissue
  • Supports cardiovascular health
  • Supports healthy immune system
  • Supports a healthy inflammatory response
  • Promotes healthy brain function
  • Supports healthy metabolism
  • Supports healthy joints

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.

Helps me stay asleep


Started taking 5HTP about two weeks ago hoping to improve my sleep. I take 2 capsules nightly and do think it is helping. I’m looking forward to see if it continues to improve my sleep.

Not Yet Convinced

I’m struggling with Insomnia. Easily can fall asleep, but I awaken. Three weeks ago just started adding a tablet each night to 10 mg of Melatonin. First week was great. Now I’m back to awakening at 3 a.m. I’m just not sure if it’s working for me.

Another winner!

I’m a terrible sleeper - I have been for most of my life. I read an article from NWW about sleep and that magnesium and 5HTP might help. I called NWW and Carla answered. She listened to my insomnia story and then we started talking about what might help. She suggested Mixed Magnesium and this product. Oh my goodness! I couldn’t be happier. I take 2 of these and 3 Magnesium an hour before bed and 7 of 8 nights I have fallen asleep for 8+ hours. I say if you’re a bad sleeper, give these products a try. Thanks Carla for listening and helping me.

Great product

Take late evening which works for me!
