Main highlights- WITHOUT ADDITIVES: One capsule contains 220 mg L tryptophan powder and nothing else.

- VEGAVERO – From Nature, with Passion, For You: We respect and love nature. That's why all our supplements are vegan and free of any unnecessary artificial ingredients.

We produce our products in Germany, where they are all analyzed and certified by independent laboratories. Furthermore, we register every product with the Ministry of Health.
- EXPERIENCE GOOD 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.
- NATURAL & PURE TRYPTOPHAN POWDER: Contrary to other L-Tryptophan pills, our Tryptophan supplement is naturally sourced from fermentation. Also, other sleep- or mood supplements often contain synthetic substances and can have a lot of negative sides effects. All our amino acid nutritional supplements are regularly tested by an independent German laboratory and our l-tryptophan powder has a certified purity of at least 99%.
