Description
NOW Foods L-Tryptophan 500mg – Essential Amino Acid Veg Capsules
NOW Foods L-Tryptophan 500mg offers the essential amino acid L-tryptophan in convenient vegetarian capsules. Tryptophan occurs naturally in foods such as turkey, dairy, seeds and oats, and the body uses it to produce serotonin and melatonin. The 500mg dose is easy to adjust, whether you take one capsule or more as directed. It is a popular amino acid for evening supplement routines.
Key Benefits
- Essential amino acid – tryptophan must come from the diet because the body cannot make it.
- Flexible 500 mg dose – a lower-strength capsule that is easy to tailor to the label directions.
- Serotonin building block – the body converts tryptophan into serotonin and then melatonin.
- Vegetarian capsules – plant-based vcaps rather than gelatin.
- Two bottle sizes – choose a smaller bottle to try or a larger one for value.
Who Is It For?
A sensible option for adults who want to add tryptophan to their routine at a moderate dose, including gym-goers, shift workers and anyone who prefers an evening supplement ritual. The vegetarian capsules suit most diets.
Flavours & Sizes
Available in 2 sizes: 60 vcaps and 120 vcaps. The larger bottle offers better value per capsule for regular users.
FAQs
Should I take tryptophan with food?
It is usually taken between meals or with a light carbohydrate snack, as protein-rich meals contain other amino acids that compete for absorption.
Is it safe with antidepressants?
Tryptophan may interact with some medicines, including antidepressants. Speak to your GP or pharmacist before use if you take any medication.
