Why Eye Drops Aren’t Fixing This
You know the routine.
By mid-afternoon your eyes feel heavy, dry, gritty.
You reach for eye drops. They help for twenty minutes. Then it’s back.
Eye drops add moisture to the surface. That’s all.
They can’t reach the muscles inside your eye that fatigue
from hours of close-range screen focus.
The problem isn’t on the surface of your eye. It’s inside it.
In Japan, this was recognised twenty years ago.
Millions take a daily antioxidant called astaxanthin —
a red pigment from microalgae that deposits directly in eye tissue.
Multiple clinical trials have studied it specifically in screen users.
The results are worth your attention.
5 Reasons This Is Different From Anything In Your Eye Care Routine
Clinically studied in screen users — results in 4 weeks.
That’s the result from a placebo-controlled trial of 82 heavy computer users who took astaxanthin for 4 weeks. Their eyes’ ability to refocus — the exact function screens exhaust — measurably improved.
A separate trial confirmed the pattern: focusing power improved significantly in the astaxanthin group. Biosphere delivers 12mg daily — above the doses used in every published study. Not a token amount. A therapeutic dose.

6,000× more powerful than vitamin C.
ANTIOXIDANT POTENCY INDEX
Relative free-medical
The most powerful antioxidant ever measured
Based on published antioxidant potency measurements in peer-reviewed research.
Published research measures astaxanthin’s free-radical neutralising power at 6,000 times vitamin C.
Peer-reviewed antioxidant potency data, not marketing.
Your eyes generate more oxidative stress per hour of screen time than almost any other organ.
Astaxanthin is the single most powerful antioxidant ever measured — and it has a specific affinity for eye tissue.

It targets the tired-focus feeling — and works in weeks, not months.
Astaxanthin deposits at the front of the eye, in the muscle that controls focus. This is the muscle screens exhaust. Lutein and zeaxanthin work differently — they accumulate at the back of the eye and take 6–9 months to build up. Astaxanthin showed clinical results in 4 weeks.
They complement each other. But if your main problem is screen fatigue, dry eyes, and end-of-day blur, astaxanthin targets the right mechanism.
Your body actually absorbs it
Most astaxanthin supplements waste your money. The ingredient is fat-soluble — deliver it alone and most passes through unused. Every Biosphere softgel includes a specialised absorption complex with olive oil, shown to enhance uptake of fat-soluble antioxidants by up to 12× compared to standard delivery.
And while your eyes get the primary benefit, published research shows astaxanthin also supports skin hydration, joint comfort, and cardiovascular health. Eyes first. Skin and joints follow.
If it doesn’t work, you don’t pay
No fine print. No hoops. Take it for two months.
If your eyes don’t feel different, we refund every cent.

Astaxanthin is vital for us all in this aging process. Every blessing we can get for all round health and optimal function is a bonus. We are grateful for the bioavailable source. Regards Steve and Fiona
I have tried many supplements over the years. Some I’ve stopped using because I didn’t notice a difference. I Will always aim to keep astaxanthin as part of my stack. I have noticed such an amazing change in my skin. My skin has always been good, but this has taken it to another level. I love this product! I particularly love the Biosphere brand as they use olive oil in the capsules, rather than seed oils. Really happy to support this NZ company.
Great product, I have been using it to help my eyes feel more comfortable ( post menopause) , they are definitely less scratchy than they were! I can’t wait to try the magnesium yet, it looks really good.
We both have the best sleep usimg this product. I am about to put in another order.
Lovely flavour and works really well.
I rely on 'Sleep' to help my sleep. Its a vial part of my evening ritual. I notice when I dont take it
Great for dry eyes. Best I've tried
Take this every night for restless legs and sleep . Alternate between the 2 flavours
Very good product but I did have to adapt it. I found taking it just before bed it would give me a hit of energy. So I no take it with dinner or just after around 7 and it gives my body time to process the ashwaganda. I still do have trouble sleeping but I do feel the nights I do sleep it’s a deeper sleep. I am going through a lot of stress and biological changes but I do feel it has helped just not as much as I hoped. The flavour is delicious and the customer service was awesome. I’m going to try the plain magnesium next time as I think ashwagandha not well suited to me
Great product - slept soundly :)
Love this product, after my first month I have far more mobility, energy and stamina, will be purchasing more...
I haven't gotten my very first bottle yet, but I will be ordering more. Capsules are easy to swallow, and makes it easy that need to take with food . Easy to remember with breakfast
On my second month of astaxanthin, not much change except a little more energy generally. Will give it a full three months.
I am so happy with my Astaxanthin . Can’t believe that it has worked so quick at pain relief . I have tried lots of other products in many years and I think this is the best thing I have tried . I have no pain and it so good . I hope this keeps up I have arthritis and and a few joint replacements so always in pain . Thank you
Awesome flavour magnesium for a massive day in the mountains!!!
Both flavours are nice and the powder mixes well. No longer getting night time cramps, so very happy with this. Will definitely be continuing with this product.
Awesome product.
I've been taking Biosphere Nitric Oxide for just over 5 weeks now. Before I started my blood pressure was in the 140s/150s/ 90s. This month I have only had one spike and my daily readings are consistently lower with some now in the ideal or normal range. I am really pleased with this result so far.
Ive been taking these now for a little over a month an just love the way my skin feels, an how its helped me not getting any flu this winter . As a shift worker doing 12 hr shifts I think its really been a great help getting me thru the day. I highly recommend them.
This magnesium is almost magic, I have had hip pain for several years and 5 weeks in it had totally gone. Unfortunately its a little hard on my stomach so have had to cut down the dose to half, I can just feel my hip pain a little again with the half dose. I will try supplementing the half dose with Astaxanthin next order.
I was getting regular muscle cramps at night and in the 30 days I trialled Biosphere Magnesium I only got a cramp once or twice. Since then I tried another brand of magnesium but haven't had the same success. Mixes easily and the lemon-lime flavour I tried us pleasant to drink.
I’ve been taking Bio sphere Nitric Oxide for a couple of years now as part of my supplement protocols. I workout at the gym and also do a lot of breathwork and this compliments everything I do.
It tastes good, easy to use, and I've halved my blood pressure tablet. It seems to be working for me and I intend to remove the blood pressure tablet totally in a week or so. It's coming on holiday with me!
Take it with my morning decaf that has coconut milk - so I am taking 2 capsules with some fats. Recently had people commenting on how nice my skin is looking. I am 60yo and recovering from cancer treatment.
Really happy with the magnesium powder, mixes well, tastes great and is now part of my daily routine.
Perfect start to my day…great flavour and definitely an improvement showing in my blood pressure levels!
The lemon/lime Magnesium powder is delicious and refreshing. It certainly is helping reduce cramps and helps me get to sleep quickly and sleep for longer periods.
I take magnesium after the gym to help with cramp.
Onto my first jar and already have a back up ready to go. Tastes delicious . Even bought a new bottle to use .
My husband is slowly reducing his blood pressure medication by using Nitric Oxide. Blood pressure is finally reducing
Been taking Astaxanthin for about 6 weeks now and definitely notice my eye and skin health is better, also seem to have a bit more energy.
A nightly routine, super power sleep when I take the magnesium - such a distinctly better sleep than nights I don’t take it.
I’ve recently changed to Biosphere Magnesium and will be reordering. It is so easy to take and adjust the amount as needed. I particularly like the Mango Pineapple flavour and take it just before bed to stop leg cramps.
Great product
I have this in the morning. Great tasting and refreshing. Great start to the day
I have found this the only product, after many years of finding something to help my sleep. My sleep for past 13 years been erratic due to menopause and hectic life. I have used this for a month now with only a couple of bad nights sleep. I sleep through until 5.00am. Hallelujah. Thank you Biosphere. Great product. Also just started using your hydrate supplement. I'll see how that goes over next month too.
I've been forgetting to wear my prescription glasses, it's been 3 months. My hair is a little darker, my nails are stronger and my skin has a summery glow. Hoping for some relief to my joints....
Easy to take and Good value for money!
The longer I take these the better I have been feeling
I started using astaxanthin on 13 May 2026. I live with chronic inflammation that often leads to headaches and migraines, and since beginning the supplement I’ve noticed a meaningful shift. My baseline inflammation feels lower, and the frequency and intensity of my headaches and migraines have reduced. Another unexpected change has been with my eye floaters. They used to be a daily nuisance, but over the past weeks they’ve improved noticeably. This is simply my personal experience and not a medical conclusion. Yet the changes have been significant enough for me to share.
