A while back, my father stumbled upon some guy with a funny accent taking remarkably high doses of pure melatonin powder: 1000 milligrams a day.
His curiosity sparked a journey down the proverbial rabbit hole. After countless hours of research (and retina-bleeding eye strain), we discovered something surprising: melatonin offers far more benefits than just better sleep.
This article shares our experience testing two leading bulk melatonin powder brands head-to-head, plus the evidence-based benefits we discovered along the way. No marketing hype—just honest, tested insights.
Melatonin: More Than Just a Sleep Aid
If you’re like most health-conscious adults, you’ve probably heard of melatonin as a sleep supplement. But did you know its benefits extend far beyond helping you drift off? Here’s what the research shows:
Evidence-Based Benefits of Melatonin Beyond Sleep
- Immune Support: Particularly effective when combined with vitamin C (ascorbic acid), melatonin helps bolster your immune response. Studies indicate it can modulate immune cells, potentially aiding in conditions involving oxidative stress or inflammation (Mount Sinai – New York).
- Heart Health: Research suggests melatonin’s antioxidant and anti-inflammatory properties provide cardioprotective effects, potentially lowering blood pressure and improving cholesterol profiles by reducing oxidative stress in the cardiovascular system (Mount Sinai – New York).
- Fibromyalgia Relief: A randomized, placebo-controlled study showed significant symptom reduction in fibromyalgia with melatonin alone or when combined with fluoxetine (Prozac), helping address both pain and associated sleep disturbances (Mount Sinai – New York).
- Digestive Support: Melatonin has shown promise against both IBS (reducing abdominal pain) and GERD (blocking stomach acid secretion) (Mount Sinai – New York, Healthline).
- Anxiety Reduction: Particularly effective for pre-surgical anxiety, with studies showing benefits in up to 80% of patients (NCCIH).
- Neurodivergent Support: While it’s not been shown to improve behavioral symptoms, melatonin supplementation has been found to promote sleep in children with ADHD and autism. Contrary to what you might expect, we neurodivergent folk often need more melatonin support, not less (Mount Sinai – New York).
- Menopausal Support: Improves sleep problems in menopausal women and may prevent bone loss in perimenopausal women, restoring quality of life without addressing hot flashes (Mount Sinai – New York).
- Cellular Protection: Acts as a powerful antioxidant, protecting cells from oxidative damage by neutralizing free radicals. Research highlights its role in preventing cell damage, with implications for overall cellular protection (Healthline).
- Circadian Rhythm Regulation: Beyond sleep, melatonin regulates the body’s internal clock, influencing physiological processes such as body temperature, blood pressure, appetite, hormone production, and blood sugar levels (Johns Hopkins Medicine).
- Cancer Research: Studies show potential anti-cancer properties, particularly in breast cancer (when combined with tamoxifen, may shrink tumors in over 28% of women who did not respond to tamoxifen alone) and prostate cancer (improved survival in 9 out of 14 men with metastatic prostate cancer when used with conventional treatments) (Mount Sinai – New York).

Our Verdict
While both products delivered similar effects, the experience of using PureBulk was significantly better. We found ourselves hesitating to take the BulkSupplements version due to the unpleasant taste—and when it comes to supplements, consistency is key to seeing results.
Remember Buckley’s cough syrup slogan, “It tastes awful, but it works”? We disagree with that philosophy. Effectiveness and palatability matter, especially for something you’ll take daily.
Why suffer through a bitter taste when you don’t have to?
Our Personal Experience with High-Dose Melatonin
After extensive research, we decided to try higher doses than typically recommended. Here’s our approach:
- Daily Intake: At least 1500mg daily. We take doses of approximately 700mg each, one at daytime and one at evening, each together with ascorbic acid (vitamin C). For more information on the vitamin C products we use, see our article on vitamin C (coming soon). One of these currently is PureBulk ascorbic acid bovine capsules. While veggie capsules are also available from them, we prefer bovine. More on that later.
- Benefits We’ve Seen:
- Improved sleep quality (deeper, more restorative rest)
- Significantly faster immune response when fighting illness
- Likely additional benefits we’re not directly noticing (cellular protection, etc.)
- How We Dose It:
- Set aside a glass of water with a teaspoon.
- Get one leveled scoop of powder using a PureBulk 1/4 tsp measuring spoon.
- Next, take the glass of water and scoop half a teaspoon of water.
- Take the 1/4 tsp scoop of melatonin powder and dump it onto the teaspoon.
- Take the whole thing under your tongue, and swoosh it around with the water. This is sublingual dosing which increases bioavailability. Do this for about 15 seconds.
- Finally, once you’re done with that, swallow the melatonin powder with the glass of water.
- Take great care when scooping and dumping the melatonin powder. It is very fine. Bits and pieces dropped here and there may trigger sneezes.

Important note: The doses we take are much higher than standard recommendations. Most sources suggest starting with 0.5-1mg and not exceeding 10mg daily. Our high-dose approach follows specific research protocols and might not be appropriate for everyone. Always consult a healthcare provider before significantly increasing any supplement dosage.
The Only Side Effect
We experienced no adverse reactions from taking either melatonin powder. The only noticeable side effect we’ve found is that our urine develops a distinctive aroma. It’s difficult to describe, but you’ll recognize it.
This is completely normal and not cause for concern.
Did You Know? Melatonin Facts That Might Surprise You
- Age-Related Decline: By age 40, our natural melatonin production begins to destabilize. By 90, we produce less than 20% of what we did as young adults (Cleveland Clinic). This may contribute to the sleep issues many experience as they age.
- Supplementation Complements, Doesn’t Interfere: Taking melatonin supplements doesn’t reduce your body’s natural production of melatonin—it adds to it.
- Daytime Effects Vary: Melatonin affects different people differently during daylight hours. Some feel energized, while others might feel sleepy from the same dose. This variation is normal and relates to your individual sleep-wake cycles. (see Doris Loh and the research she cites)
- Sleep Deprivation’s Role: If melatonin makes you sleepy, it might be addressing underlying sleep debt. According to peer-reviewed research, your pre-existing sleep-wake state actually influences how melatonin affects you. If you’ve been chronically sleep-deprived (even mildly), melatonin may initially make you sleepy as it helps restore your natural sleep cycle. (see Doris Loh and the research she cites again)
Why Most People Get Melatonin Wrong
Many assume melatonin simply “puts you to sleep,” but the truth is more nuanced. Melatonin doesn’t force sleep—it signals your body that it’s time to sleep. The distinction is subtle but important.
This explains why:
- Some people take melatonin and feel nothing
- Others take it and sleep deeply
- Still others experience improved sleep quality without feeling drowsy when taking it
Rather than a sedative, think of melatonin as a regulator helping restore your body’s natural rhythms. This perspective aligns with research showing its broad physiological impacts beyond sleep.
Making Melatonin Work For You: Practical Tips
- Start Small: If you’re new to melatonin, begin with a standard dose (0.5-3mg) before considering higher amounts.
- Consistency Matters: Take melatonin at roughly the same time each day to help regulate your circadian rhythm.
- Measure Precisely: With bulk powder, accurate measurement is essential. While a small digital scale works, PureBulk’s measuring spoons make this easier.
- Mix If Needed: If you find the taste challenging, mix the powder with a small amount of water, juice, or applesauce.
- Give It Time: Some benefits may be immediately noticeable (sleep quality), while others (immune support, heart health) might take longer to perceive.
- Track Your Results: Keep notes on how you feel, your sleep quality, and any changes in overall wellbeing to assess effectiveness.
