## Overview

SIERRA LIFE SCIENCES Melatonin Bulk Powder offers a clean, non-GMO, and allergen-free sleep aid designed for adults with busy, screen-heavy lifestyles. With customizable dosing from 2mg to 5mg and an enormous 100g supply yielding up to 50,000 doses, it delivers unmatched value and flexibility.

## Description

Sierra Life Sciences Melatonin Capsules are designed for adults seeking reliable sleep support as part of a consistent nighttime routine. The easy-to-swallow capsule format fits seamlessly into daily habits and supports a healthy sleep-wake cycle when occasional late nights, travel, or schedule changes disrupt normal rhythms. Modern lifestyles often interfere with the body’s natural melatonin production. Evening exposure to screens, artificial lighting, and irregular schedules can make it harder to unwind at night. Establishing a calming bedtime routine—paired with a clean, straightforward melatonin supplement—can help signal the body that it’s time to rest. Manufactured in the USA in a cGMP-certified facility using Non-GMO ingredients, Sierra Life Sciences Melatonin Capsules offer a simple, dependable option for customers who prefer a clean-label sleep supplement focused on nightly consistency and overall sleep quality.

Review: Good quality but be careful - I'll start out by saying that I was a bio minor with a lot of chemistry and bio lab exposure. If I weren't, I would avoid this like the plague. Most people don't understand how small a milligram is and without some special skills and equipment, trying to measure a 2 mg dose is futile. Do yourself a favor and dilute this to a concentration that's easier to dose. If you're wondering, "How do I do that?", this might not be for you. All of that being said, this is the cheapest way to go for pure melatonin. I do not doubt the stated purity here. Understand that melatonin is a powerful hormone and, as with all hormones, "more" is not "better", especially if you're using it only as a sleep aid.
Review: Good stuff! - This melatonin is definitely potent. Lights out all night for me. I take 1 gram. I was taking 80mg of a different brand but I would wake up sometimes and it would take me a hour to go back to sleep. I only wish they gave you more.

### ⭐⭐⭐⭐⭐ Good quality but be careful
*by C***H on November 26, 2025*

### ⭐⭐⭐⭐⭐ Good stuff!
*by R***I on November 20, 2025*

This melatonin is definitely potent. Lights out all night for me. I take 1 gram. I was taking 80mg of a different brand but I would wake up sometimes and it would take me a hour to go back to sleep. I only wish they gave you more.

### ⭐⭐⭐⭐⭐ LIGHTS OUT! HELLO MR SANDMAN!
*by D***N on May 31, 2025*

I was taking the "high dose" melatonin pills for a long time due to working shift work for 25+ years. They worked okay but when I grew the testicular heft to try something new I tried this....... AND IT WAS LIGHTS OUT! I bought a MG scale so I could accurately figure out the dosing and I've been using the 100mg 50K dose bag and I haven't even used half of it yet in 2+ months! I lost a lot of my taste and smell when i caught that big bad virus 2 years ago and never got it back so from what i can tell it doesnt taste bad at all, i use a small measuring spoon and take a certain amount (marked inside of measuring spoon) and put it on my tongue and swish with water the swallow! DO NOT BREATHE IN WHILE TAKING IT BECAUSE IT BURNS THE THROAT QUITE A BIT. Within an hour of taking it me and Mr Sandman are sitting on the river bank perch jerking, it's the best sleep I've gotten in YEARS! Shift work has jacked up my circadian rhythm and I can't get it back now that I aint working shift work anymore. If you ask me if this is something I'd recommend heck yes to anyone working shift work and need to get more than 4 hours sleep during the day get ya some of this it'll change your life! AND NO THERE ISNT ANYONE OR ANY COMPANY SUBSIDIZING THIS REVIEW I GET NOTHING FOR THIS REVIEW I WROTE IT FOR THOSE WHO NEED SLEEP AND CANT SEEM TO GET IT BECAUSE IVE SPENT TOO MANY DAYS & NIGHTS STARING AT THE CEILING FAN GOING ROUND AND ROUND AND ROUND! People need sleep to function!
