⭐ 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. 🌿 VEGAVERO – From Nature, with Passion, For You: We respect and love nature.
