The clinical-dose Hawaiian protocol adults 45+ are switching to.
Most antioxidants ship 4 mg — the dose used in animal safety testing, not the dose that moved human biomarkers. Primenia ships the actual 12 mg from 60+ peer-reviewed trials.

Doctors, professors, runners, teachers. The Hawaiian astaxanthin protocol — in their own words.
“I check the labels. Most astaxanthin on the shelf ships 3 to 4 mg — the dose used in animal safety testing. Primenia is the first I've seen at the clinical 12 mg from peer-reviewed human trials.”
“I take three supplements daily. After 18 months on Primenia, it's the only one I'd refill if I had to choose. The clinical dose, the Hawaiian source, the third-party labs — they checked every box my pharmacy never did.”
“Started this after a knee flare. Stayed on it because everything else got incrementally better — energy, recovery, skin, sleep. Not a single product change can do all that, but if you're going to bet on one antioxidant, bet right.”
“I've tried everything. After 65, you stop expecting miracles from a supplement. I expected nothing from Primenia. Five weeks later I was demonstrating poses without warming up. The Hawaiian source matters.”

Astaxanthin is a powerful carotenoid your body cannot produce on its own. Sourced from Hawaiian microalgae cultivated under intense sunlight, it neutralizes free radicals up to 6,000x more effectively than vitamin C.
Unlike most antioxidants, astaxanthin crosses both the blood-brain and blood-retina barriers — reaching cells that other nutrients can't, and protecting skin, vision, joints, and brain from oxidative stress at the source.
Daily use of 12mg natural astaxanthin supports:
• Skin elasticity, hydration, and UV defense
• Joint comfort and faster recovery
• Eye health and screen-fatigue resilience
• Cardiovascular function and circulation
• Cellular protection from inflammation linked to oxidative stress
Studies also associate it with improved endurance, mental focus, and overall energy.
Most customers notice improved skin tone, reduced fatigue, and better focus within 2–4 weeks.
After 8–12 weeks of consistent daily use, deeper benefits become visible: smoother skin texture, fewer fine lines, sharper vision in low light, and noticeably better joint mobility.
Astaxanthin works at the cellular level, so consistency matters more than dose. One softgel a day with a meal containing fat is the optimal protocol.
Designed for adults 18+ looking for science-backed support for skin, eyes, joints, and overall wellness.
Vegan, gluten-free, soy-free, non-GMO. Manufactured in the USA in a CGMP-certified facility, third-party tested for purity and potency.
If you are pregnant, nursing, on blood thinners, or have a known allergy to algae or shellfish, please consult your physician before starting.
Take Primenia daily for 90 days. If you don’t see firmer skin, sharper vision or more energy, send us one photo and we refund 100% — pouchs too. Keep them.
Why so generous? Because 96% of our customers reorder. BioShield-12™ isn’t a gamble — it’s a clinical-dose formulation we use ourselves.
Primenia is single-ingredient — just astaxanthin and the carrier oil that helps it absorb. Nothing else. No fillers, binders, or marketing-blend padding.
The full clinical dose used in published research — not the under-dosed 4–6 mg you find in most multi-ingredient blends.
Extracted from Haematococcus pluvialis grown in the high-UV sunlight of Hawaii — never chemically synthesized.
Astaxanthin is fat-soluble. Olive oil triples bioavailability vs the dry-powder formulations sold by most competitors.
Every batch is independently verified for potency and purity in cGMP-certified facilities registered with the FDA.
“
In thirty years of nutritional research I’ve seen one molecule consistently outperform every other antioxidant in cellular protection studies. BioShield-12™ is the only formulation I take every day myself — at the clinical dose Primenia delivers.
Astaxanthin is fat-soluble — the small choices below make the difference between “maybe” and “wow.”
Same time every day. Set a reminder for the first two weeks — after that it becomes automatic.
Eggs, avocado, olive oil, nuts — any meal with a bit of fat triples astaxanthin absorption.
Astaxanthin builds up in tissues. Most customers notice the change between weeks 2 and 6.
Most “antioxidants” on the shelf can’t reach the cells that actually need them. BioShield-12™ is the only molecule clinically shown to cross every cellular barrier.

Three months in and the difference in my skin tone and afternoon energy is something even my husband noticed. One pill with breakfast is the easiest habit I’ve ever kept. The 90-day guarantee is what made me try, but I’m staying for the actual results.
After 50, I tried every antioxidant on the shelf. Astaxanthin from Primenia is the first one I actually feel — my joints don’t complain after long walks anymore and the eye fatigue from screens is way down. Will keep ordering.
Bought it for the eye benefits (10+ hours on screens daily). Stayed for the focus and the calmer skin. Took about 4 weeks before I noticed the shift, then it just kept getting better. The fact that it’s third-party tested and made in the US sealed it for me.
Take BioShield-12™ daily for 90 days. If you don’t see visibly firmer skin, sharper vision, or more energy by day 60, send us a single photo and we refund you 100% — and let you keep the pouch. No return shipping. No restocking fee. No “maybe.”
We can only make this promise because 96% of customers reorder. BioShield-12™ works gradually — the full 90 days lets your cells regenerate, so you actually see the change in the mirror, not just on a label.
Astaxanthin is fat-soluble and accumulates in tissues over time. Most customers report changes in skin tone and daily energy between weeks 2 and 6. For joint, eye and longer-term benefits, the published research suggests 8–12 weeks of consistent use.
Astaxanthin has a strong safety profile across decades of clinical literature. We use a 12 mg dose — in line with the strongest published studies. Always check with your healthcare provider before starting any new supplement, especially if you take blood thinners, hormone medication, or are pregnant or nursing.
The astaxanthin oleoresin is sourced from a Hawaiian-grown microalgae cultivator (Haematococcus pluvialis). The softgels are encapsulated and pouchd in the USA in cGMP-certified facilities registered with the FDA. Every batch is third-party tested for purity and potency.
One softgel a day, ideally with a meal that contains some fat (breakfast works well). Astaxanthin is fat-soluble — taking it with food roughly triples absorption. Consistency matters more than timing.
Then you don’t pay. Our 90-day money-back guarantee covers opened pouchs too. Just email hello@primenia.com within 90 days of receiving your order and we’ll refund you in full — no return required.
Free shipping on orders of 2+ pouchs within the United States. Orders are processed within 1–2 business days and typically arrive in 5–7 business days via USPS, UPS, or FedEx. We currently ship within the U.S. only (50 states + APO/FPO).
