helpfull

It's not as strong as Night's Rest from the same company, but still it works. I fall asleep faster and wake up more rested without grogginess. Since this one is without melatonin, one can use it more often. I use both products, but recently my sleep became better, so for now just if I go to sleep later than usual. very happy with this formula

These pills have changed my life. They help me fall asleep and stay asleep. They are more effective than expected. Great product. One con is that the pills are rather large to swallow.

This works!!

I take just half the recommended dose at bedtime and find I get to sleep quickly and soundly. There’s no grogginess in the morning, either. I’m glad I don’t have to rely on Ambien to sleep now.

good

The capsules are easy to swallow and sit lightly in my stomach, with no aftertaste. I notice a smoother transition to sleep within about 30 minutes and fewer awakenings during the night, which leaves me feeling more rested in the morning. for me this blend helps align my body clock without leaving me groggy at sunrise.

Quality is good. Ingredients seem to be good. The size is fine. The dosage I can't comment on. The benefits are again something I can't comment on. There is no taste.

I’ve probably gone through about 5 bottles of this now. It works great especially if you don’t take it every night to avoid tolerance. I alternate with magnesium and melatonin.

Great

Not bad after taking a couple of days. Make my skin look good and smooth. Take a tablet every morning after meal. The quality of the product is perfect and nice. I will take it every morning to get a better result. The ingredient is pure, no chemicals. I like the product and will buy it next time.

This is really good quality, there's no aftertaste, the ingredients are clean, it's easy to swallow. The size of the package is great and it lasts a long time. Benefits to health are proven, it's been great so far. This product is one of my top 5 prsocuts and consistently used in rotation with other vitamins.

Not sleepless for long anymore!

I have always had trouble getting to sleep from time to time. This product totally changed that. The bottle's suggested dosage is 2 to 4 tablets taken 30 to 60 minutes before bed time. I generally take 2 tablets, but I rarely make it to 30 minutes before conking out! I tend to be low on B vitamin levels, so I suspect that the niacin and B-6 help my sleep, as well as some of the other ingredients, like Valerian root and Chamomile flower extract. The size of the tablets seems a bit large, but I have never had any trouble swallowing them. I purposely bought a larger bottle this time because I know this product works for me!
