fullspan astaxanthin helps you take back...

To stay at your prime, your antioxidant defenses have to keep up with the daily hits - stress, screens, short sleep, processed food. The damage builds quietly, then shows up everywhere at once: your focus, your energy, your heart, the way you move. One softgel fights it at the source.

What's Really Stealing Your Energy, Focus and Vitality

Every day, invisible attackers called free radicals are damaging your cells from the inside. They come from things you can't avoid: stress, screens, poor sleep, processed food and pollution. And at your prime age, your body's own defenses can't keep up.

Free radicals attack the cells in your brain, joints, eyes, organs and skin. This silent attack is a hidden driver behind Alzheimer's and dementia, arthritis and joint degeneration, vision decline, weakened immunity and many other forms of accelerated aging.

✕ A "healthy diet" can't fix this: astaxanthin is barely in the food you eat. You'd need about 3 fillets of wild sockeye salmon every day to get 12 mg.

✕ Multivitamins aren't built for it: most contain no astaxanthin at all - just tiny doses of everything, spread too thin to matter.

✕ Prescription drugs have a hidden cost: they can mask symptoms, but the side effects can leave you feeling worse - fatigue, dizziness, nausea, digestion problems. Trading one problem for another.

The Only Antioxidant That Reaches Where the Damage Happens

Often called nature's most powerful antioxidant, astaxanthin has been studied for decades for its role in protecting the body from oxidative stress (50+ human clinical trials).*

While most antioxidants work only in the watery or only in the fatty part of the cell, astaxanthin's unique shape lets it span the entire cell membrane - right where oxidative damage begins.*

And fullspan gives you the full 12 mg in one softgel, suspended in olive oil so your body actually absorbs it.

fullspan Astaxanthin works throughout your entire body, helping you feel steadier, clearer and more capable in daily life.*

It's about staying independent, active and confident as the years go on - not slowing down before you have to.

What to Expect From Daily Use of fullspan Astaxanthin

Astaxanthin builds up in your body over weeks, not hours. Here's what daily use typically looks like.*

  1. Within Days

    Building up

    As astaxanthin builds in your system, you may start feeling less worn down by the end of the day. Less eye strain, lighter stiffness, or just feeling a bit more steady overall.*

  2. Within 4 Weeks

    First signals

    This is when many people notice clearer thinking, better daily energy and less discomfort when moving, reading or using screens - when you start feeling more like yourself again.*

  3. After 8 Weeks

    The pattern

    With consistent use, the benefits tend to feel more noticeable and reliable: easier movement, more comfortable vision, sharper focus and a healthier inflammatory response.*

  4. After 3 Months

    Long-term protection

    This is where long-term protection starts to matter. More confident in your body, more independent, keeping up with everyday life. The goal isn't a quick fix - it's aging on your terms, staying sharp and doing what you love.*

One softgel instead of four

My old astaxanthin had me taking four capsules a day. This is one with dinner and I actually remember it. Six weeks in, my morning walks feel easier too.*

Why fullspan Astaxanthin CRUSHES the Usual Fixes

Your body has its own antioxidant defenses, but stress, screens, poor sleep and age burn through them faster than most routines can keep up. Here's how fullspan compares to what most people are already taking.

fullspan compared with other astaxanthin brands and generic multivitamins
Feature MERIDIANMARK Other astaxanthin brands Generic multivitamins
Full 12 mg in one softgel Yes No No
Natural microalgae source, not synthetic Yes No No
Paired with tocotrienols + rice ceramides Yes No No
Made to the MERIDIANMARK™ standard Yes No No
90-day money-back guarantee Yes No No
Underdosed or split across 4 pills No Yes Yes
  • The full 12 mg - in one softgel

    Many brands sell 4-6 mg per softgel or split 12 mg across four a day. fullspan puts the full 12 mg, the daily amount used in 12-week human studies, into one softgel.*

  • Natural, not synthetic

    Synthetic astaxanthin is made from petrochemicals and has a different molecular shape. Ours comes from Haematococcus pluvialis microalgae - the natural form used in human research.

  • Oil-based softgel

    Astaxanthin is fat-soluble. A dry tablet or powder capsule is poorly absorbed. Our softgel carries it in extra virgin olive oil, so it's absorbed with your meal.*

  • Tested in the softgel you swallow

    Made to the MERIDIANMARK™ standard: every lot is tested by an independent lab for purity and potency - in the finished softgel, not just the raw powder. Scan the lot number on your pouch to see the report.
