What Changed For Them

Verified customers on the nights, the mornings and the mirror.

★★★★★

"Oura sleep score went 68 to 86 in 18 days."

Day 4 was my first night of deep sleep over 1hr 40min. This is the first magnesium that made my brain feel different, not just my muscles.

"I'm 64 and my skin looks better than it did at 55."

Serums, retinol, all of it. My sister asked if I got a facial. I hadn't. Texture, tone and the redness all changed within 6 weeks.

"My wife noticed before I did."

Waking at 3AM every night for over a year. Melatonin, cheap glycinate, gummies, none of it moved. Night five was the first time I slept through.

After 4 months she said my macular pigment density had improved. She asked what I changed. She wrote it down.

Why they belong together

Magnesium runs more than 300 reactions in your body, including the ones that build your own antioxidant defences. Astaxanthin picks up where those defences run out. One keeps the engine running. The other stops it from wearing out.

FAQ

Questions, Answered

If sleep, stress, focus, cramps or a steady heart rhythm is your main goal, start with Magnesium Complete. If you're already on magnesium, or you care most about your heart and kidneys, your skin or your eyes, add Astaxanthin.

Yes. They were designed to sit side by side. Most customers take Astaxanthin in the morning with breakfast and Magnesium Complete before bed. If you take medication or have a medical condition, check with your healthcare provider first.

With Magnesium Complete most customers report better sleep within 7 to 14 days, with clarity building over the following weeks. Astaxanthin builds up in your tissues, so it's weeks, not days. Most people notice their skin first, then their eyes, and the full glow builds over 2 to 3 months. That's why the bundles give you a longer runway. Individual results vary.

Subscribe & Save gives you the lowest price, free shipping and free gifts on bundles, with refills every 4 weeks. You can pause or cancel anytime from your subscription portal.
