You shouldn't have to think about your eyes this much.
Drops wear off in minutes. The dryness always comes back.
There's a reason, and it's not on the surface of your eye.

Drops before work. Drops at lunch. Drops before bed.
A bottle on the desk. One in the car. One on the bedside table. You've tried three or four brands. Some sting less than others. None of them last more than twenty minutes.
Contacts felt like sandpaper by noon, so you stopped. You avoid cinemas with heavy air con. You used to read at night. Now you can't face another screen or page. People ask if you're tired. You're not tired. Your eyes have been red for months. Maybe years.
You've been to the optometrist. They said dry eye syndrome. Use lubricating drops. You're already using them six times a day.
And it's getting worse. The drops used to last longer. The flare-ups used to be less frequent.
Dry eye isn't a moisture problem. It's an inflammation problem.
Your tears aren't just water. They have an oily top layer that stops them evaporating. Without that oil, your tears disappear in seconds.
The oil comes from tiny glands along your eyelids. When those glands get inflamed, they clog. No oil, no protection. Your tears evaporate faster than your eyes can produce them.
Drops replace what evaporates. They can't fix why it's evaporating.
And if you're over 40, it's getting harder.
Hormonal shifts around perimenopause reduce tear production directly. Dry eye affects twice as many women as men. After 50, it climbs sharply.
Your body is producing less. Your glands are working worse. And nothing you put on the surface changes either of those things.
The antioxidant your eyes are missing.
You’ve probably never heard of astaxanthin. It’s the molecule that makes wild salmon pink. The one that protects their muscles through the brutal upstream swim to spawn.
And unlike most antioxidants, it actually reaches your eyes. It crosses the blood-retinal barrier and deposits in ocular tissue, and has been shown in clinical trials to improve tear production.
6,000× more powerful than vitamin C.
Published research measures astaxanthin’s free-radical neutralising power at 6,000 times vitamin C.
Your eyes generate oxidative stress every day. This is the only antioxidant that’s both strong enough to neutralise it and targeted enough to reach them.

What the research actually shows.
In a clinical study of 60 people with dry eye, 30 days of oral astaxanthin significantly improved tear film stability, eye surface health, oil gland function, and overall symptom scores.
A separate study found improvements in tear production, redness, and eye pain within one month.
12mg daily. The dose that matches the research.
Clinical studies used 6 to 12mg per day. Biosphere delivers 12mg. The top of the range used in published research.
Not a token amount. The dose designed to produce the results the research showed.
Two softgels with breakfast. That’s it.

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.

Frequently Asked Questions
How long until my dry eyes improve?
The clinical study showed significant improvement in tear film stability and dry eye symptoms within 30 days. Some customers report less dryness in the first 1 to 2 weeks. Benefits build over time.
What if it doesn't work?
60-day money-back guarantee. Email us for a full refund. No questions, no hassle. You don't even need to return the bottle.
Can I still use my eye drops while taking this?
Yes. Astaxanthin works from the inside while drops work on the surface. Many customers find they gradually need drops less often as astaxanthin builds in their system, but you don't need to stop drops to start this.
Is 12mg the right dose?
Clinical studies on dry eye used 6 to 12mg daily. At two softgels, you're getting 12mg. That matches or exceeds every published study dose.
Will this help with meibomian gland dysfunction?
The clinical study showed improvement in the glands along your eyelids that keep your tears from evaporating too fast. After 30 days, gland function and the quality of the oily layer in the tear film both improved. When these glands work properly, your tears last longer.
I've tried omega-3s for dry eyes and they didn't help. How is this different?
Different mechanism. Omega-3s provide anti-inflammatory fatty acids. Astaxanthin is a targeted antioxidant that crosses the blood-retinal barrier and deposits directly in eye tissue, including the structures that control tear production. The clinical evidence for astaxanthin in dry eye is more specific.
What actually is astaxanthin?
A naturally occurring antioxidant from microalgae. It's what gives salmon their pink colour. Published research ranks it among the most powerful antioxidants ever measured, and it has a specific affinity for eye tissue.
Can I take this long-term?
Yes. Astaxanthin is non-habit forming and does not build tolerance. Benefits are cumulative. Many customers take it as part of their daily routine for months or years.
Is it safe with my medications?
Astaxanthin is well tolerated and safe to combine with most supplements and medications. If you're on blood-thinning medication, check with your doctor first.
Where is this made?
Astaxanthin extracted from microalgae using a solvent-free CO₂ process. Every batch independently third-party tested. Manufactured in a GMP-certified facility in West Auckland.
