Natural factors is such a great quality brand! They standardize ingredients and test potency, which isn't the norm in most supplements. I decided to try this supplement after reading how adding 5HTP can be helpful with serotonin issues. I have found it to help with stress and mood during a really stressful time in my life.
This product is working well for me. I tried 100mg and it was too much/unnecessary, so now I take 50mg. Also, at first I was taking regular 5 htp but switched to time release, which is so much better. This brand seems to have good quality at a good price as well. I take one of these in the evening an hour before bed and then I take 500 mg of tyrosine in the morning to lift both my dopamine and serotonin (not just the serotonin with the 5-htp) and keep everything in balance. I find it's working well so far.
I highly recommend this supplement. I have had such a hard time sleeping for the last few years, with little to no help from other supplements. I took one capsule, and slept 7.5 hours on the first night! Every night I take one, I sleep better. Very highly recommend!
This is the only 5-htp I take. There is no side effects at all. I'm a longtime insomniac. It helps me fall asleep faster and sleep like a baby when I take it with Nature Factors' Pharma GABA and 3mg melatonin. It also reduces my anxiety. I'm very happy with this product.
