Source of an essential amino acid for the maintenance of good health.

L-Tryptophan is a large neutral amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3) which assist in the regulation of sleep, positive mood and immune function. L-Tryptophan is not synthesized by the body and must be obtained from the diet. As a component of dietary protein, tryptophan is particularly plentiful in chocolate, oats, bananas, dried dates, milk, cottage cheese, meat, fish, turkey, and peanuts.

Ideal for those wishing to boost serotonin levels.

Each capsule contains:

L-Tryptophan 220 mg

Non-Medicinal Ingredients: Veg Capsule (hypromellose, water), Cellulose, Stearic Acid, Hydroxypropyl Methylcellulose.

Adult Dosage: Take 1 capsule daily with meals.

It seem to help my sleep. I take it along with gummies.

Will order again

Very pleased to have ordered this product from Vitasave. I previously ordered this from another online source, but after they were out of stock for months, I needed another source. I would like to support businesses in my local area, but at the closet store I tried that stocks this (this is not a widely available product) I suspect they do not store the product in appropriate conditions as I suddenly needed 3 capsules for the same affect where I normally use 2. The product I received from Vitasave has returned me to my usual dose. Vitasave has a new customer in me. I use this for sleep, to fine tune my dose in conjunction with 500 mg pills from another brand, which do not cut well and are mg for mg stronger (and melatonin.)

Great for SAD

I start taking this every fall.
Helps me sleep soundly and feel rested and alert in the morning. Feel happy and motivated despite the weather.

usually hard to find, glad it's here

it's usually hard to find a good tryptophan supplement that's 220mg which is perfect. most are 500 - 1000mg and that's WAY TOO MUCH, hence why it makes a lot of people feel unwell in those reviews. i find the NOW brand researches and knows their supplements very well which explains why this is actually the proper dose (the daily recommended intake for tryptophan is 200-250mg i believe, so these guys are spot on). i am personally a low serotonin type, so i usually take one a day to keep my levels up, or sometimes half a one if i just need a little bit and not a full dose, this is a must for me so i'm always ordering this and extra bottles to keep stocked up, as when i'm without or miss a day or two i can definitely feel it. at the time of writing this i've ordered probably several and will continue to do so without a doubt! remember to take with food or a little snack so it assimilates in your body and you don't feel unwell!

A magic combo

I take this along w/ L-Tryptophan and L-Theanine...for me this is a magic combo... along w/ a "circadiuan rhythm reset", and I now sleep like a baby after horrible months/years of very little sleep. TG!
