Gluten Free Promotes Sleep With Slow Release Dietary Supplement Ultra Tested cGMP Melatonin is a hormone that is produced in the brain by the pineal gland from serotonin. It is used primarily as a sleep aid. It is also commonly used to reduce jet lag. Low melatonin levels are considered a very common cause of sleeplessness. Several double-blind studies have shown that melatonin supplementation is effective in promoting sleep when melatonin levels are low; however, if an individual takes melatonin when levels are not reduced, then it reportedly has no effect. For individuals who are deficient in glutathione, melatonin is important because it stimulates the production of glutathione peroxidase. This versatile nutrient is also a powerful antioxidant. In addition, it works to stimulate phosphorylation of pyridoxine in the brain and facilitates the formation of pyridoxal 5-phosphate. Melatonin may also help in the methylation process, which is important in the body’s absorption and utilization of vitamin B6.

Sleep and wake without the grogginess of pharmaceuticals

Have bought this product for myself and my 85 year old mother who has suffered from insomnia for many years. It has helped her immensely to fall asleep and get back to sleep after waking to go to the bathroom. She wakes feeling free and not groggy from pharmaceuticals. I have the same result.

These extended-release melatonin tablets have been a lifesaver for my restless nights—I fall asleep faster and stay asleep longer. Love that they’re free of unnecessary additives and gentle on my stomach. The 150-count bottle is a great value compared to other brands. Only downside? Waking up too refreshed and almost missing my alarm!

GREAT

This extended-release melatonin is a standout sleep aid, especially for those who struggle with staying asleep through the night. The slow-release formula gradually delivers melatonin over 2–4 hours, helping maintain restful sleep without grogginess in the morning. Each tablet contains 2.5 mg of melatonin, a gentle yet effective dosage. Since using it, I’ve experienced more consistent sleep and easier mornings. It’s a high-quality product that delivers on its promise. Good benefit.

Good quality, but unfortunately didn't work for me

Kirkman is a high quality brand, however the ER melatonin unfortunately didn't work for me, it caused a significant loss of sleep quality and I had a headache in the morning. It's not for everyone and I suggest doing more research to make sure EX melatonin is right for you.

Bun

As needed this product works really well, for me this means using only once or twice a week, and so, it works really well. They have a pleasant taste and dissolve slowly under the tounge. The time from over the lips and into a pleasant sleep is 15 to 20 minutes. Highly recommend!

Sleep Quality Improved in Just 5 Days!

I’ve been looking for a supplement that could help me fall asleep faster and stay asleep longer. After trying several options, I finally found Kirkman Labs’ Melatonin Extended Release. The results have been nothing short of amazing. I started taking one tablet one hour before bedtime, as recommended. Within just five days, I noticed a significant improvement in my sleep quality. I used to wake up feeling groggy and tired, but now I feel more refreshed and alert in the morning. The extended-release formula ensures a steady supply of melatonin throughout the night, which has helped me avoid those mid-night awakenings. The capsules are small and easy to swallow, and there’s no unpleasant taste or smell. The packaging is also compact and convenient, making it easy to carry around. I’ve compared this product to others on the market, and it stands out for its effectiveness and affordability. It’s a great value for money, especially considering the quality of ingredients and the cGMP certification. Overall, I highly recommend this melatonin supplement to anyone struggling with sleep issues. It’s made a world of difference for me, and I plan to continue using it. If you’re looking for a reliable sleep aid, give this a try— you won’t be disappointed!
