The Science Behind It
Astaxanthin is one of the most extensively studied antioxidants in human clinical research. At 12mg per softgel — sourced from Haematococcus pluvialis microalgae — it delivers a meaningful dose backed by clinical research across eye and retinal health.
What makes astaxanthin uniquely suited to eye health is where it can actually reach. The vitreous gel inside your eye and the retinal cells behind it are protected by the blood-retinal barrier — a selective filter that blocks most antioxidants from ever getting in. Astaxanthin is one of the few that crosses it, concentrating directly in the ocular tissues where oxidative stress drives floater formation, visual decline, and retinal cell damage.
Once inside, its molecular structure does something no common antioxidant can: it spans the full thickness of the cell membrane — anchoring on both the inner and outer surface simultaneously. Vitamin C can only work on the exterior. Vitamin E reaches one side. Astaxanthin protects the whole wall, from within. This is why it tests up to 6,000 times more powerful than vitamin C in standard antioxidant assays — and why it never turns pro-oxidant the way vitamin C can under certain conditions.
In eye health research, astaxanthin has been associated with improved macular blood flow, reduced digital eye-strain symptoms, support for tear-film stability, and defence of the vitreous and retinal cells against the oxidative degradation that drives floater formation and visual decline over time.
Formulated with MCT oil for fat-soluble absorption, so the astaxanthin is delivered in the form most readily taken up by the body.

What Sets Our
Astaxanthin Apart?
Most astaxanthin supplements on the market look identical on the label — but there are critical differences that determine how much your body actually receives. Here's why ours stands out:
Clinically Dosed at 12mg
Many astaxanthin supplements use 4mg or less — doses too low to replicate what clinical research actually used. Our formula delivers 12mg per softgel from natural Haematococcus pluvialis microalgae, matching the dose used across multiple published human trials on eye and retinal health.
Formulated with MCT Oil
for Maximum Absorption
Astaxanthin is fat-soluble — without the right carrier, most of it passes through unabsorbed. We formulate with MCT oil to ensure the astaxanthin is carried efficiently into the bloodstream, so the dose on the label is the dose your body actually uses.
Clinically Studied for Eye & Retinal Health
Astaxanthin is one of the most clinically studied antioxidants in human research — with trials spanning vitreous and retinal health, macular blood flow, digital eye strain, dry eyes, and visual clarity. It crosses the blood-retinal barrier to reach the ocular tissues directly, where most antioxidants simply can't get.
Sustainably Sourced
from Microalgae
Our astaxanthin is derived from Haematococcus pluvialis — the natural microalgae source considered the gold standard for purity and potency. Sourced responsibly and extracted without synthetic astaxanthin or artificial additives, so you get the real thing, nothing else.
Customer First Approach
Your results and satisfaction are our priority. If you have any questions, our support team is here every step of the way — and if our Astaxanthin isn't right for you, our 60-day money-back guarantee means you have nothing to lose.

What Real Customers
Are Saying
"I've had little dots and the occasional wispy thing floating around for years, and I'd mostly learned to live with them. Then about eighteen months ago I got a new one that was much bigger and darker and that was it. I couldn't look at anything without it being right there in the middle of everything. I went back to the optician and was told again that everything looked fine and to try not to focus on them. Easy to say. I started wearing sunglasses indoors at one point because the office lighting was making it worse, which my colleagues found a bit odd. I came across this while reading about oxidative stress and the vitreous, which sounds very technical but I'd gone down quite a rabbit hole by that point. I've been taking it for about four months now. The big floater is still there but honestly it bothers me less than it used to and the little ones are completely gone! I go whole hours now without thinking about them, which sounds like a small thing but genuinely isn't. I think my eyes have just felt calmer overall."
"I'm on screens all day for work and my eyes have been getting really bad over the last year or so. Dry, tired, struggling to focus the longer the day goes on. I was using eye drops a lot. I heard about this being good for dry eyes so I tried it quite randomly without thinking it'd really solve the issue but I had to try something. About two weeks in I just noticed I wasn't reaching for the drops as much and my eyes just felt a lot more energised. Less dryness and fatigue. It's easy to take, I take one a day with breakfast."
"I've had floaters for about three years. The doctor kept telling me my eyes were perfectly healthy, which I'm sure they were, but that wasn't really the point. I couldn't enjoy being outside on a sunny day without being completely distracted by them. That grey stringy one in my right eye was the worst. They're so annoying and distracting you just can't forget about them. It's constant. They were really making me miserable. I tried bilberry tablets, lutein, some eye vitamin stack I found online. Nothing made any difference that I could honestly say was real. I wasn't expecting much from this either if I'm being truthful. After about five or six weeks I just started noticing I wasn't catching them as often, and sometimes hours would go by without me noticing. They haven't all gone completely but I can definitely say they seem to have faded a lot. I don't dread going outside on a bright day the same way I used to. My daughter noticed I seemed less anxious generally, which she didn't even know was connected to my eyes. I'll be taking this daily as I'm still seeing improvements but I also really don't want them to return."
