About Source Naturals

Source Naturals has been a trusted name in the supplement industry since 1982, consistently delivering high-quality products. Their manufacturing facilities adhere to strict Good Manufacturing Practise (GMP) standards, ensuring each batch meets rigorous quality controls. This L-Tryptophan formula embodies their commitment to purity and thoughtful ingredient selection.

Key Ingredients: L-Tryptophan and Coenzyme B-6

L-Tryptophan is an essential amino acid found naturally in protein-rich foods such as turkey, eggs, and cheese. In supplement form, it provides a concentrated source to support serotonin synthesis. Source Naturals use exceptionally pure L-Tryptophan, regularly tested to guarantee high standards.

Pyridoxal-5'-phosphate (P-5-P) is the active coenzyme form of vitamin B-6. Unlike pyridoxine hydrochloride, P-5-P is immediately usable by the body, eliminating the need for conversion. This is crucial because vitamin B-6 acts as a cofactor for the enzyme that converts tryptophan to serotonin. By including P-5-P, this formula helps ensure efficient serotonin production.

What Is L-Tryptophan with Coenzyme B-6?

This supplement combines pure L-Tryptophan with the active coenzyme form of vitamin B-6, pyridoxal-5'-phosphate (P-5-P). L-Tryptophan is an essential amino acid that serves as a precursor to serotonin, a neurotransmitter involved in mood regulation, appetite control, and sleep. Vitamin B-6 is a necessary cofactor for the conversion of tryptophan to serotonin, so providing the active form (P-5-P) may enhance this process. Each tablet supplies 500 mg of L-Tryptophan plus a coenzyme B-6 boost, making it a popular option for those seeking to support a calm mood and healthy sleep patterns.*

Key Benefits of L-Tryptophan Supplementation

L-Tryptophan is renowned for its role in supporting the body's natural serotonin production. Serotonin contributes to feelings of wellbeing and relaxation and helps regulate the sleep-wake cycle. By supplying the raw material for serotonin, this supplement may help promote a balanced mood and restful sleep. The addition of P-5-P ensures that the conversion process has the necessary cofactor, potentially maximising the effectiveness of the tryptophan.*

Many individuals use L-Tryptophan to unwind after a stressful day or to maintain a positive outlook. It may also support cognitive function during periods of occasional stress.* As with any supplement, individual results vary, and it is best used as part of a healthy lifestyle.

How to Choose an L-Tryptophan Supplement

When selecting an L-Tryptophan supplement, purity and quality are paramount. Look for products tested for contaminants and manufactured under Good Manufacturing Practise (GMP) standards. Source Naturals meets these criteria, with regular testing to ensure purity and potency. The form of vitamin B-6 also matters—P-5-P is the active coenzyme form, more readily used by the body than pyridoxine hydrochloride. Dosage is another consideration; 500 mg per tablet is a common and effective amount, with flexibility to adjust based on your needs. Always follow the suggested use on the label and consult a health care professional before starting any new supplement regimen.
