  • NATURAL & PURE: Contrary to other products, our Tryptophan is natural (from fermentation). Also, other Sleep/Mood supplements containing GABA or 5-HTP often are synthetic and can have a lot of negative sides effects. Moreover, our product is regularly tested by an independent German laboratory and has a certified purity of at least 99%.
  • #128270; WITHOUT ADDITIVES: One capsule contains 500 mg L-tryptophan and nothing else. In fact, our supplement does not contain any additives commonly found in other products such as magnesium stearate, microcrystalline cellulose or even gelatine. Our capsules are therefore 100% vegan and non-GMO. Per bottle: 120 capsules. Recommended daily dosage: 1 capsule.
  • MOOD & SLEEP: L-Tryptophan is an essential amino acid. However, it is not produced by the body and it must be obtained from the diet. Besides being essential for the synthesis of proteins, it is the precursor of serotonin and melatonin. Serotonin is the so-called "good mood" hormone which regulates mood, cognition, and behaviour. Melatonin, on the other hand, controls the sleep-wake cycle. Thus, L-tryptophan supports the body in several different ways.

L-Tryptophan Plus Vegavero | Highly Dosed- 600mg per Day | with Added Magnesium, Vitamin B6 & Valerian Extract | NO Additives | 100% Vegan | 120 Capsules
  • SLEEP & ANXIETY: L-Tryptophan is an essential amino acid and the precursor to serotonin and melatonin. Serotonin is the "good mood" hormone which regulates body functions like mood, cognition, appetite, or behaviour. Melatonin is known for its influence on the sleep-wake cycle. Thus, L-Tryptophan plays an important role in mood and sleep support and since it is not synthesised from the body, we need external sources to obtain it.
  • SYNERGISTIC COMBINATION: To our natural L-Tryptophan we added Magnesium and Vitamin B6 *which contribute to normal functioning of the nervous system and to normal psychological function. Moreover, they are components in the process that converts tryptophan into serotonin. We also added Valerian - a flowering plant, which has been widely used to treat sleeping disorders. Thus, our supplement is the perfect alternative to synthetic supplements like sleep tablets or prescribed Melatonin.
  • HIGH QUALITY INGREDIENTS: Since high quality is our guiding principle, our Tryptophan Plus supplement contains natural Tryptophan from fermentation, natural Magnesium from sea water, Valerian extract standardised to Valerenic acid, and Vitamin B6.

5HTP High Strength 400mg - 60 capsules - 400mg 5-HTP Serving from 410mg Pure & Undiluted 1:1 Griffonia Seed Extract - 5 HTP Supplement
  • UNDILUTED 98% GRIFFONIA SEED EXTRACT – 5HTP is produced from the seeds of the Griffonia simplicifolia plant, in the form of an extract. A lot of manufacturers reduce the plant to 12.5% (8:1 extract), potentially losing significant portions of the material. Using a special extraction process, SuperSelf preserve the chemical spectrum of the plant, creating a 98% pure extract.
  • MAXIMUM STRENGTH 5 HTP SUPPLEMENT – This high strength SuperSelf 5HTP supplement contains 400mg of 5HTP per serving from 410mg pure 1:1 Griffonia seed extract. Each package contains 30 servings (60 capsules). Don't be mislead by competitors claiming 400mg of the 8:1 extract containing only 50mg of 5-HTP. 5HTP rarely occurs in nature and is not found in any foods, so cannot be supplemented through diet alone.
  • SEROTONIN PRODUCTION – A natural form of 5HTP, this SuperSelf supplement increases the quantity of the L-5 hydroxytryptophan amino acid in the body. Our bodies use 5HTP in serotonin production. Serotonin is used in the brain to regulate many important bodily functions and sensations. Increasing serotonin availability is believed to have a number of benefits.
  • TESTED FOR PURITY – SuperSelf 5-HTP supplement has been manufactured to GMP standards and tested by independent laboratories for potency and purity. Please be aware that 5-HTP may negatively interact with several medications, including those used to increase serotonin production. Talk to your doctor about the dosage and to ensure it’s safe for you to use. Some people may experience dose-dependent side effects, such as nausea, diarrhea, and stomach pain when taking 5-HTP supplements.
  • A BETTER WAY TO SUPPLEMENT – Live your best life, whatever your age, state of health or previous lifestyle. The SuperSelf team create supplements designed to help you live well for longer. A percentage of profits from this purchase will go to Vitamin Angels, reducing preventable diseases in children under the age of five in 70 countries worldwide.

5HTP High Strength 400mg - 60 capsules - 400mg 5-HTP Serving from 410mg Pure & Undiluted 1:1 Griffonia Seed Extract - 5 HTP Supplement
  • UNDILUTED 98% GRIFFONIA SEED EXTRACT – 5HTP is produced from the seeds of the Griffonia simplicifolia plant, in the form of an extract. A lot of manufacturers reduce the plant to 12.5% (8:1 extract), potentially losing significant portions of the material. Using a special extraction process, SuperSelf preserve the chemical spectrum of the plant, creating a 98% pure extract.
  • MAXIMUM STRENGTH 5 HTP SUPPLEMENT – This high strength SuperSelf 5HTP supplement contains 400mg of 5HTP per serving from 410mg pure 1:1 Griffonia seed extract. Each package contains 30 servings (60 capsules). Don't be mislead by competitors claiming 400mg of the 8:1 extract containing only 50mg of 5-HTP. 5HTP rarely occurs in nature and is not found in any foods, so cannot be supplemented through diet alone.
  • SEROTONIN PRODUCTION – A natural form of 5HTP, this SuperSelf supplement increases the quantity of the L-5 hydroxytryptophan amino acid in the body. Our bodies use 5HTP in serotonin production. Serotonin is used in the brain to regulate many important bodily functions and sensations. Increasing serotonin availability is believed to have a number of benefits.
  • TESTED FOR PURITY – SuperSelf 5-HTP supplement has been manufactured to GMP standards and tested by independent laboratories for potency and purity. Please be aware that 5-HTP may negatively interact with several medications, including those used to increase serotonin production. Talk to your doctor about the dosage and to ensure it’s safe for you to use. Some people may experience dose-dependent side effects, such as nausea, diarrhea, and stomach pain when taking 5-HTP supplements.
  • A BETTER WAY TO SUPPLEMENT – Live your best life, whatever your age, state of health or previous lifestyle. The SuperSelf team create supplements designed to help you live well for longer. A percentage of profits from this purchase will go to Vitamin Angels, reducing preventable diseases in children under the age of five in 70 countries worldwide.
