I've said goodbye to insomnia! At 9 PM, I take a third of a capsule of this Melatonin and by 10 PM, I'm asleep! The quality is beyond reproach! ❤️

Melatonina TOP
Verified Purchase
As always, I don't buy any other melatonin on the market because this one offers both the performance and the ideal mg for the body. 100% recommended. I usually buy melatonin for a year and return it the next, so shipping is free and I don't worry about running out. :)

High dosage.
Verified Purchase
I was using the more regular 3mg melatonin, but after reading about the benefits of a higher dosage and the diminishing effects of 3mg I decided to get this brand. After taking just half a tablet I could feel the quality of this brands melatonin ingredient and it does feel cleaner.

Effective Sleep Aid with Value
Verified Purchase
I've been using NaturesPlus Melatonin 20 mg tablets for a few weeks, and they've significantly improved my sleep quality. The high-potency formula helps me fall asleep faster and stay asleep throughout the night without feeling groggy in the morning. The tablets are easy to swallow and free from unnecessary fillers, which I appreciate. With 90 tablets per bottle, it's excellent value for the price. I highly recommend this product for anyone seeking a reliable and effective sleep aid.

🔍 What is this product? Melatonin Supplement (Natural Sleep Hormone) 20 mg Dose → Considered very high. 90 tablets (3-month supply). Helps: Fall asleep faster, improve sleep quality, reduce nighttime awakenings. ⭐ Benefits: Regulates the biological clock (sleep/wake cycle). Useful for: Insomnia, jet lag (time difference). Helps with deeper sleep and better awakenings. ⚠️ Important Point (Very Important) ❗ A 20 mg dose is very high. Most people only need: 0.5-5 mg. Up to 10 mg is considered strong. 👉 This product: is only suitable for severe cases or after trying lower doses. Not suitable for beginners at all. 💊 How to Use: One tablet 30 minutes before bedtime, but it's best to start with half a tablet or less (if you can divide it). ⚠️ Warnings: Causes strong drowsiness. Do not use: for pregnant or breastfeeding women, or those under 18 years of age. Do not use for extended periods without a break. Consult a doctor if you have: high blood pressure, depression, or chronic illnesses. 🧠 My Honest Review ✔️ Very strong and effective for deep sleep ✔️ Suitable for those suffering from severe insomnia ❗ However: The dosage is excessive for most people. May cause: morning drowsiness, dizziness, disturbing dreams 📊 Quick comparison (to help you understand) Dosage Usage 1-3 mg Starter/Mild problems 5 mg Moderate 10 mg Strong 20 mg 🔥 Very strong (special cases) 💡 My advice to you if it's your first time using melatonin → Don't start with this. It's best to start with: 3 mg or 5 mg. Use 20 mg only if: You've tried the lower dose and it didn't work. If you want, I can recommend the best dosage suitable for you based on your exact problem (difficulty falling asleep/sleeping)

Thank you.

This is an excellent dietary supplement that helps with sleep and regulating the biological clock. I recommend it for those who need it and suffer from insomnia, anxiety, or interrupted sleep, but without overusing it. It should be used only when needed, God willing. From what I've read, it should be taken for three consecutive days only, after which it will help regulate your sleep schedule. Its effectiveness varies from person to person; it may be beneficial for some.
