Source Naturals L-Tryptophan with Vitamin B-6, 1000mg, 60 Tablets

Health Benefits of L-Tryptophan with Vitamin B-6

• Mood Support: L-tryptophan is a precursor to serotonin, which contributes to normal mood. This formulation may help maintain emotional balance during periods of occasional stress.*
• Relaxation and Sleep: The conversion of tryptophan to melatonin supports natural sleep cycles, making it easier to fall asleep and stay asleep.*
• Niacin Production: Tryptophan is also a precursor to niacin (Vitamin B-3), which supports energy metabolism and skin health.*
• Nervous System Function: Vitamin B-6 is essential for neurotransmitter synthesis and nerve signalling.*

How Does the Combination Work?

L-Tryptophan is an essential amino acid that the body uses to produce serotonin and melatonin—two key compounds that regulate mood, relaxation, and sleep. When taken as a supplement, L-tryptophan may help promote a calm, positive outlook and encourage restful sleep. This formulation from Source Naturals pairs L-tryptophan with Vitamin B-6 (pyridoxine), which acts as a cofactor in over 100 enzymatic reactions, including the conversion of tryptophan into serotonin and niacin. By including 10 mg of Vitamin B-6 per tablet, this product helps ensure efficient utilisation of tryptophan, potentially providing more consistent support for mood balance and sleep quality compared to tryptophan alone. Vitamin B-6 also contributes to normal homocysteine metabolism and red blood cell formation.

Recommended Dosage and Usage

The suggested uses is 1 tablet 1 to 2 times daily, between meals and preferably with fruit juice to enhance absorption. For those seeking restful sleep, 2 tablets may be taken before bed. Each tablet provides 1,000 mg of L-tryptophan and 10 mg of Vitamin B-6. As with any supplement, it is best to start with the lowest effective dose and adjust as needed under the supervision of a health care professional.
