SUPPORTS MOOD & SLEEP: L-Tryptophan is an essential amino acid known for its role in producing serotonin and melatonin, key neurotransmitters that help support emotional balance and healthy sleep patterns. Ideal for promoting calm and restfulness, especially during times of stress.
FAST-ACTING FORMULA: Delivered in a convenient vegan capsule with free-form amino acids, our L-Tryptophan supplement offers quicker absorption as it bypasses the need for digestion, allowing your body to utilise the L-Tryptophan efficiently and effectively.
ESSENTIAL AMINO ACID: As an essential amino acid, L-Tryptophan cannot be produced by the body and must be obtained through diet or supplementation. This 220mg dose provides a reliable source of this vital nutrient to support daily well-being and neurotransmitter production.
