Source Naturals L-Tryptophan with Coenzyme B-6 500mg - 60 Tablets

Key Ingredients and How They Work

Each tablet contains 500 mg of L-Tryptophan, an essential amino acid that acts as a precursor to serotonin. The body converts serotonin into melatonin, which helps regulate sleep-wake cycles. By providing this building block, the supplement supports natural sleep and a balanced mood.

What makes this formulation special is the inclusion of Coenzyme B-6 (pyridoxal-5-phosphate), the active form of vitamin B-6. This coenzyme is vital for the enzymatic reactions that turn tryptophan into serotonin and niacin. Without sufficient B-6, the metabolism of tryptophan may be less effective. Together, these ingredients work synergistically to promote neurotransmitter synthesis and overall wellbeing.

Who Benefits from Source Naturals L-Tryptophan with Coenzyme B-6?

This supplement is ideal for adults looking to support restful sleep and maintain a positive mood naturally. L-Tryptophan is an essential amino acid that the body use to produce serotonin and melatonin. If you occasionally struggle with sleep or want to unwind without resorting to harsh chemicals, this product could be a valuable part of your evening routine. It is also suitable for those with dietary sensitivities, as it contains no yeast, dairy, egg, gluten, corn, soy, or wheat. It is free from sugar, starch, preservatives, and artificial colours, flavours, or fragrances.

Recommended Dosage and Usage

The suggested dosage is one tablet three times daily, taken between meals and ideally with fruit juice to aid absorption. For those specifically aiming for restful sleep, taking three tablets before bedtime is recommended. Each bottle contains 60 tablets, providing up to a 20-day supply at the sleep-support dose.

For best results, use consistently as part of a calming bedtime routine. Avoid taking with high-protein meals, as competing amino acids can reduce tryptophan uptake. Fruit juice helps transport it across the blood-brain barrier.

How Source Naturals L-Tryptophan Compares to Competitors

Founded in 1982, Source Naturals has over 40 years of experience in the supplement industry. Their commitment to quality is clear in this formulation, which avoids common allergens and artificial additives. The inclusion of Coenzyme B-6 (the active form) rather than less active vitamin B-6 sets this product apart by supporting efficient tryptophan metabolism.

Many sleep aids rely solely on melatonin, but L-Tryptophan offers a precursor approach that the body can regulate naturally. This may be preferable for those seeking a non-habit-forming option. The tablets are manufactured in the USA under current Good Manufacturing Practises (cGMPs), ensuring consistent quality and purity.

Potential Side Effects and Safety

L-Tryptophan is generally well tolerated, but some individuals may experience mild drowsiness, nausea, or headache. These effects are often temporary. To minimise risk, start with a lower dose and gradually increase if needed. Do not exceed the recommended dosage.
