Serotonin is a neurotransmitter in the brain associated with positive moods and restful sleep. To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce.
In the body, tryptophan has been shown to:
- improve sleep
- enhance mood
- modulate stress
The basis for this formula is premium L-tryptophan, which has undergone significantly more rigorous manufacturing processes than regular tryptophan material to assure the highest purity and safety.
Read the entire label and follow the directions carefully prior to use.
Take one (1) capsule 1 to 3 times daily on an empty stomach, or as recommended by a healthcare practitioner. For maximum absorption, take with a small amount of carbohydrate, such as diluted juice. Best if taken separately from protein and amino acids.
Vegetable cellulose (capsule), microcrystalline cellulose, ascorbyl palmitate, silica, medium chain triglycerides.
Store tightly closed in a cool, dry place.
Caution: Consult your healthcare provider before taking this product if you are taking prescription medications (e.g. MAOI and SSRI antidepressants) for depression. Concomitant use of L-tryptophan with antidepressant medications has the potential to increase the risk of serotonin syndrome, characterized by symptoms like confusion, sweating, agitation, nausea, involuntary muscle contractions, and racing heartbeat. Do not use L-tryptophan before driving or operating heavy machinery.
- Keep out of reach of children.

great product to reduce inflammation and relax. No magnesium stearate in it too which is good news as Magnesium stearate and stearic acid kills your T-cells.

My favourite supplement! L.E.F is my favourite brand. No added extra ingredients, works like a dream. Like with all other supplements, I double each dose or triple the dose to be quickly effective.

I can feel the difference, and yes it put me to sleep fast! However, I ordered it for Depression, and I can say, I feel a difference in how I feel, not so weighed down, and I am being more productive.
