I’m down 47 lbs on Wegovy. Week 10 of Primenia my mom said ‘your cheeks are back.’ I cried in the kitchen. The $1,800 filler consult I had booked? Cancelled.

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.
Less than 0.5% of customers use our 90-day money-back guarantee.

“
Rapid fat loss on a GLP-1 floods the body with oxidative stress that breaks down collagen faster than it can be rebuilt. This is the mechanism behind “Ozempic face.” The only intervention I’ve found that addresses it at the cellular level — without injections or stopping the protocol — is clinical-dose astaxanthin. Primenia delivers it at the exact 12 mg the literature uses.

Why we built Primenia
In 2024 something changed in my GLP-1 practice. Patients were down 30, 40, 50 lbs — and asking the same question across the exam table: “I love the weight loss. Why does my face look 10 years older?”
The clinical data on astaxanthin was unambiguous — but no commercial supplement delivered the dose the research actually used. Most ship 4 mg. The studies showing real cellular protection used 12 mg. The gap between ‘supplement’ and ‘therapeutic dose’ was a chasm patients were falling through.
So we built Primenia. One molecule. The 12 mg clinical dose. Sourced from the same Hawaiian microalgae strain every published study used. Lot-tested for purity. And a 90-day promise: if you don’t feel like yourself again, we refund you in full and you keep the pouch.

How to take it
Three steps. One minute. The easiest part of your day.
Astaxanthin is fat-soluble — the small choices below make the difference between “maybe” and “wow.”
1
Take 1 softgel with breakfast
Same time every day. Set a reminder for the first two weeks — after that it becomes automatic.
2
Pair with a healthy fat
Eggs, avocado, olive oil, nuts — any meal with a bit of fat triples astaxanthin absorption.
3
Stay consistent for 28 days
Astaxanthin builds up in tissues. Most customers notice the change between weeks 2 and 6.
How it stacks up
BioShield-12™ vs fillers, Sculptra & doing nothing
Fillers mask the symptom. Sculptra rebuilds slowly but injects. BioShield-12™ stops the oxidative collapse rapid GLP-1 fat loss causes — at the cellular source. Works alongside your GLP-1.
| Primenia | Dermal Fillers (Juvéderm / Restylane) | Sculptra (PLLA) | Doing Nothing | |
|---|---|---|---|---|
| Addresses root cause (oxidative collagen loss) | ✓ | ✗ | Partial | ✗ |
| Needles / clinic visits | ✓ | ✗ | ✗ | ✓ |
| Cost over 12 months | $ | $1,600–$4,800 | $3,000–$5,000 | $0 (face keeps hollowing) |
| Reversible if you stop | ✓ | Partial | Partial | N/A |
| Works alongside your GLP-1 | ✓ | ✓ | ✓ | ✓ |
| Time to visible effect | Week 4–8 | Same day | Month 3–6 | N/A |
Fillers add volume on top of skin that's still losing collagen underneath — results fade in 6–12 months and require re-injection. Sculptra stimulates new collagen but requires multiple in-office sessions.
One molecule · Clinical 12 mg dose
The same Hawaiian astaxanthin peer-reviewed studies actually used.
Most astaxanthin on the shelf delivers 4 mg — a third of what every published longevity study used. We deliver the full clinical 12 mg dose, sourced from the world’s most studied microalgae strain.

Why Hawaiian astaxanthin from Haematococcus pluvialis
Hawaii’s closed-loop microalgae farms grow Haematococcus pluvialis under controlled UV stress — the same strain (NIES-144) used in 60+ peer-reviewed clinical studies, incl. Piermarocchi 2012 (Eur J Ophthalmol) & Tominaga 2017 (Acta Biochim Pol). The result is a natural, lipid-bound astaxanthin our cells absorb 4× better than the synthetic petroleum-derived form sold in most supplements.
One small softgel, 12 mg of pure astaxanthin. No fillers, no synthetic vitamins, no proprietary blends hiding under-dosed ingredients.
Lipid-bound for absorption
Fat-soluble carotenoid delivered in cold-pressed sunflower oil — 4× better absorption than dry-form (Karolinska Inst. 2018 bioavailability trial · Carotenoid Sci. 12(3)).
Cold-extraction protocol
Supercritical CO₂ extraction preserves the full molecular structure. No solvents, no heat damage, no isomer loss.

8 months on Mounjaro and I’d stopped FaceTiming my grandkids — I hated how I looked. Started Primenia in January. By March my daughter sent me a screenshot from our FaceTime saying ‘mom you look 10 years younger.’

Stayed on semaglutide for the weight. Started Primenia for the face. Under-eye hollows that aged me 10 years are visibly fuller. Husband asked what skincare I was using — I told him it’s the supplement I take at breakfast.

Frequently Asked Questions
Will it work alongside my Ozempic / Wegovy / Mounjaro?
Yes. BioShield-12™ is a cellular antioxidant — it works on a completely different pathway than GLP-1 medications. It protects collagen, hair follicles, and mitochondria from the oxidative stress that rapid fat loss creates. Your weight-loss protocol stays untouched.
When will I see fuller cheeks and tighter skin?
Most users see early changes in skin firmness and under-eye area within 4–6 weeks. Restored cheek volume and visible jawline definition typically come between weeks 8 and 12 as cellular collagen scaffolding rebuilds.
Is this an alternative to fillers or Sculptra?
Different mechanism. Fillers physically displace tissue; BioShield-12™ protects the cellular structure that gives your face its natural fullness. Many customers use both — the supplement preserves what fillers create.
Will it affect my weight loss or appetite?
No. Astaxanthin has zero impact on appetite, satiety, or metabolism. It only addresses the oxidative damage your fat loss is causing — you keep losing weight, you just stop losing your face.
What if my glow doesn’t come back?
Then you don’t pay. Our Feel-Better-or-Refund Promise™ covers 90 full days. Keep the pouch, get every dollar back. We make this offer because 87% of GLP-1 customers reorder — the result speaks for itself.
