Eyes. Brain. Joints. Skin. One molecule supports them all.
Astaxanthin doesn't target just one organ. It works wherever oxidative stress does, which is almost everywhere. Here's what that means for you.
Gets where it counts
Astaxanthin is one of the few antioxidants shown to reach eye tissue, where screens and bright light take their toll every day.
Made for screen-heavy days
Supports visual performance and helps your eyes handle long hours of screen time, so tired eyes at night don't feel like a given.
Supports focus, near and far
Supports the small muscles that shift your focus every time you look up from your phone.
Comfort you can feel
Supports eye comfort and moisture through long days of driving, reading and screens.
Reaches the brain
Astaxanthin is one of the few carotenoids that crosses the blood-brain barrier, bringing antioxidant support where your brain needs it.
Support for a hard-working brain
Your brain is about 2% of your body weight but uses around 20% of your oxygen, which makes it a hotspot for oxidative stress. Astaxanthin supports it right there.
Everyday mental sharpness
Supports mental sharpness, processing speed and healthy cognitive aging, one softgel at a time.
Clear, not jittery
No caffeine, no stimulants, no crash. This is long-term brain support, not an afternoon energy spike.
For joints you use every day
Supports joint comfort and mobility, so stairs, walks and gardening stay part of your day.
Works at the cellular level
Oxidative stress builds up in hard-working joint tissue. Astaxanthin gives antioxidant support right where the wear happens.
No routine overhaul
No stacks, no six-capsule protocols. One softgel a day supports the joints you rely on most.
Keeps up with you
Supports muscle recovery and endurance, which is why active people love it.
Beauty from within
Creams stop at the surface. Astaxanthin works from the inside, supporting skin at the cellular level where elasticity starts.
Supports elasticity and smoothness
Supports skin elasticity, moisture and smoothness, the three things that make you look rested.
Everyday sun-season support
Supports your skin's natural resilience to daily UV exposure. It's not a sunscreen, so keep your SPF, but it's real support underneath.
The pigment behind the salmon run
Astaxanthin is what makes salmon pink and fuels their swim upstream. The same molecule, now part of your morning.
Same softgel for every tab. 90-day guarantee.

Frequently Asked Questions
What is astaxanthin?
Astaxanthin is a naturally occurring carotenoid made by microalgae. It's the pigment that turns salmon, shrimp and flamingos pink. It's fat-soluble and has been studied for its antioxidant properties. It's one well-characterized compound, not a blend.
Why 12mg?
Many astaxanthin products on the market contain 4 to 6mg per serving. We use 12mg because it's the amount most often used in astaxanthin research. One softgel gives you the full amount, so you don't need to take three.
Where does your astaxanthin come from?
Ours comes from Haematococcus pluvialis microalgae, grown specifically for supplement use rather than made synthetically.
How do I take it?
One softgel a day with a meal. Astaxanthin is fat-soluble, so taking it with food that contains some fat helps absorption. No loading phase, no complicated schedule.
Is it third-party tested?
Yes. Every batch is tested by an independent lab for potency and contaminants before it ships, and we publish the certificates of analysis on our site.
Can I take this alongside medication?
If you take medication, are pregnant or nursing, or have a medical condition, talk to your healthcare provider before starting any new supplement, including this one.‡
What's in it besides astaxanthin?
No proprietary blends, no artificial colors or flavors, no added sugar and no gluten. The full supplement facts panel is on the product page.
What is the softgel shell made from?
The softgel holds the astaxanthin in an oil suspension to support absorption. Produced in a facility that also processes shellfish. If you have a shellfish allergy, check with your doctor before use.‡
