Most men over 35 are severely magnesium deficient — and standard blood tests don't catch it. Magnesium controls over 400 biological processes including sleep, energy, liver function, drive, and blood flow. When levels drop, every system degrades at once. Oolou delivers 12 bioavailable forms to restore all of it simultaneously.
Take 2 capsules before bed every night. That's it. No complicated timing windows, no stacking protocols. The formula works while you sleep — restoring magnesium levels across every system overnight.
Yes. Try Oolou for 30 days. If you don't feel a difference in your sleep, energy, or drive, we'll refund every penny. No returns required. No questions asked.
Deeper, uninterrupted sleep. Stronger drive and performance. Liver detox and recovery support. Steady energy with no afternoon crash. Sharper focus and clearer memory. All driven by 12 bioavailable forms of magnesium — each one targeting a different system simultaneously.
All Oolou orders ship free from our USA warehouse. Orders are dispatched within 1–2 working days. Domestic USA orders arrive within 3–7 working days. International orders within 10 working days.

FAQs
Different forms absorb into different tissues. Glycinate targets your nervous system, threonate crosses the blood-brain barrier, taurate reaches the heart. One form hits one system. The rest stay broken.
Most customers notice sleep improvement within 7–14 days. Energy and focus follow around week four. The full benefit — drive, liver function, mental clarity — lands between weeks 6 and 8. That's why the 90-day supply is what most customers choose.
Standard blood panels only test serum magnesium — which reflects around 1% of your body's total stores. You can be severely depleted and still show normal results. Most doctors never look deeper.
Drugstore magnesium oxide absorbs at roughly 4%. Most of it never reaches your cells — it just irritates your gut. Oolou uses 12 chelated, bioavailable forms each absorbing through a different pathway. It's not a better version of the same product. It's a different mechanism entirely.
Oolou is vegan, gluten-free, and non-GMO with no known interactions at standard doses. If you're on prescription medication, check with your doctor before adding any supplement.
Try it for 30 days. If you don't feel a difference, we'll refund every penny. No returns required. No questions asked.

I've tried melatonin, sleep sprays, everything. Nothing worked long term. Two weeks on Oolou and I'm sleeping through without waking up at 3am. I didn't realise how depleted I was.

Deeper, uninterrupted sleep
“I'd written off the afternoon fog as just getting older. Six weeks in and I'm sharp all day. My wife noticed before I did — said I seemed like myself again.”

Mental clarity returned
“Stiff joints every morning for years. I'd stopped mentioning it to my doctor because nothing came of it. Month two on Oolou and the stiffness has almost gone. Wish I'd found this sooner.”

Joints feel smoother and less painful
Three months in. Sleep is sorted, my drive is back, and I feel like myself again for the first time in years. My wife noticed before I did.

Sleep and performance restored
Didn't expect much. Bought it for the sleep and that's sorted now. But the drive is back too and my wife has definitely noticed. Three months in and I'm reordering.

Sleep restored
Digestion was a mess, energy was gone, brain fog every afternoon. Six weeks on this and all three have improved. Didn't change anything else so it has to be Oolou.

Energy and liver function improved
I'd accepted feeling sluggish as just getting older. Six weeks in and the afternoon crashes are gone, digestion has improved, and I just feel cleaner. Something shifted.

Liver detox and energy restored
I'm 58 and hadn't slept past 4am in three years. Week two on Oolou I slept until 6:30. Thought it was a fluke. Six weeks later it's still happening every night.
