Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Stress-Relax Tranquil Sleep is rated 4.4 out of 5 by 5.
Rated 4 out of 5 by from Sleeping Issues I have been taking this product along with Tryptophan for several years now. I went from 2 restless hours of sleep to at least 5-6 hours some times more. Anyone struggling with 'sleeping problems I highly recommend it, at least give it a try every body is different so amount varies. I also want to thank Swanson Vitamins for making available the high quality supplements at very fair prices.

Rated 5 out of 5 by from I love this sleep aid. I've never slept faster or better in my life, I love this supplement! I recommend it all the time. I take about a half hour before I'm ready to crash. I prefer the chewables, they seem more effective for me. This sincerely helps my brain get quiet and my sleep to go interrupted, WITHOUT any groggy symptoms in the morning. Best sleepy time help I've ever had.

Rated 5 out of 5 by from Take every night Before bed I take two capsules plus 3/4 tsp glycine (per Dr Wright), and avoid eating after 7 pm. Most nights I sleep fine. When I don't it's usually because I've had a snack/chocolate, after dinner. To determine if this melatonin is really helping I am going to skip taking it for a night or two. Stay tuned.
