Product Overview

Description

  • Foundation for Longer Life
  • Essential Amino Acid for Natural Sleep Enhancement and Stress Reduction
  • Dietary Supplement

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.

Suggested Use

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.

Other Ingredients

Vegetable cellulose (capsule), microcrystalline cellulose, ascorbyl palmitate, silica, medium chain triglycerides.

Warnings

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.
  • Do not exceed recommended dose.
  • Do not purchase if outer seal is broken or damaged.
  • When using nutritional supplements, please consult with your physician if you are undergoing treatment for a medical condition or if you are pregnant or lactating.

To report a serious adverse event or obtain product information, contact 1-866-280-2852.

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.

Thanks for your feedback!

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.
