Stark L-Tryptophan 100 grams — L-tryptophan for relaxation and sleep support

Stark L-Tryptophan is a dietary supplement with the amino acid L-tryptophan in powder form.

Tryptophan is a precursor for the synthesis of serotonin and can participate in the synthesis of niacin (vitamin B3) in the body.

The powder format is convenient for flexible dosing and use in the evening routine, particularly before bedtime.

Briefly about the product:

• Form: powder.
• Serving Size: 1/2 scoop (1000 mg).

How it works:

• Serotonin: Tryptophan is a precursor amino acid from which serotonin can be synthesized in the body.
• Melatonin: Serotonin is involved in the biochemical circuit associated with the regulation of the sleep-wake cycle.
• Niacin: Tryptophan may be involved in the synthesis of niacin (vitamin B3) in the body.
• Delivery to the brain: Tryptophan enters the brain through transport systems, where it can compete with other large neutral amino acids.
• Dosage: Taking on an empty stomach and separate from meals may be a practical approach to adherence.
• Evening routine: Taking before bed can help form the habit of “switching” to rest mode.
