Rewarded Review

I took this supplement for 40 days, two capsules a day: one in the morning and one in the evening. This amino acid started working two weeks after I started taking it. Works softer than 5-HTP, but the effect lasts longer. But unlike 5-HTP, there are no side effects. Main effects: strong and high-quality sleep, removal of negativity, mood stabilization. Helps reduce appetite, leading to weight loss with the supplement. L-tryptophan also improves physical endurance, so it can be used for training. This amino acid is best taken with vitamin D3, as it metabolizes the conversion of L-tryptophan to serotonin.

I open a capsule, pour half o the powder in a little water and drink that at bedtime - really helps make my sleep more restful and reduces the time it takes me to fall asleep. I also take it to offset the effects of caffeine when I have had too much coffee or dark chocolate and it is nicely calming.

This is good quality tryptophan. Easy to swallow sized veggie caps. Slides down your throat easily. It’s a kind of protein needed to create melatonin. It benefits restful sleep, healthy mood and behaviour. Ingredients are simple: Pure tryptophan. Comes packaged in a nice sturdy bottle with a flip lid.

I like everything about this product, good quality ingredients, perfect size of capsules makes for easy swallowing, and it gives me the energy boost I need throughout the day without interfering with my sleep at night. I take one capsule first thing in the morning about 30 minutes before breakfast and I also take one capsule 30 minutes before lunch.

I'm glad I found this. My naturopathic doctor recommended it for sleep to take with Melatonin and magnesium. It also helps me with depression. I take it with a Vit. B complex, Vit D3, and Magnesium glycinate liquid to help it work its wonders.

I love the convenience of capsules, and there is no bad taste to deal with. The ingredients are good and I'm happy with the quality. I benefit from a great sleep with this product, and have also used the 5-htp which can work better for some people.

I like this brand of L-Tryptophan, Doctors Best. It works well, I take it 45 minutes before bed to help sleep better. It lets your body make it's own serotonin and melatonin. We need both to be happy and to have deep sleep.

This is a great quality tryptophan which I have found indispensable. Even better there are no stearates or other crap fillers mixed in with it.

I take this high quality tryptophan as a sleep aid. Works better for me than normal l-tryptophan. I take it 30 minutes before going to bed and it works really well.
