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.

Overall rating: 4.8 / 5 from 1677 reviews.
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 :)
I’m loving this quality magnesium product from BioSphere as it has transformed the quality of my sleep.
I was sceptical but desperate when I started using Gut Support. After the first month, there hadn’t been a huge change, but I decided I was going to give it 2 months. Only a week into the second tub I noticed a definite change, and after not quite 2 months my system is so much calmer and more regular - the best it has been in nearly 6 years.
Nerve pain gone , deep sleeps after taking this . ! I am about to reorder , thanks guys 😍
This has been a game changer for me . It has eased pain and cramping at night . It promotes a feeling if calm and relaxation . I will never stop using this . Please buy it . I promise you won’t be sorry . Carolyn
Just love this product. I am on my third tin. I have been able to halve my blood pressure medication.
Sleep so much better and no more cramps
I won't need to ask for my money back. It works! The quality of my sleep has improved 10 fold.
Helps me stay asleep all night long
Prompt delivery and high quality. Noticed my eyesight not troubling me as much within a week.
It was a tough winter but this Biosphere Immune got us through.
I began taking this product 2 weeks ago to help with my sleep due to RLS and aching muscles due to injuries. Its great. I fall asleep well and sleep longer. I love the lemon lime flavour too!
Great quality astaxanthin and an easy addition to my daily supplement routine. I take it for its antioxidant, skin and general healthy-ageing benefits. Simple, well-dosed and no fuss. Very happy with it.
Awesome product!
Love it
Really like the flavour and taste, it encourages me to use it daily !
My husband and I have both been taking Biosphere Nitric Oxide, and we’ve been really happy with how we feel since starting it. We both feel so much better overall and have noticed a real difference in our general well-being and energy. It’s now become part of our daily routine, and based on our personal experience, we’re very pleased with it. It’s not often that we find a product that we both feel has made a noticeable difference, but this one has. We’ll definitely continue taking it!
Another one bites the dust! I’m really benefiting from taking this product every evening. I’m sleeping through the night, and waking refreshed. I would recommend this to anyone as a fuss free, easily digestible form of magnesium for settling your nervous system and allowing good sleep patterns.
Really like the Biosphere Magnesium. It's so helpful before and after hard physical work when I tend to get plagued with cramp. Alongside other salts & good hydration it's been great .Also very pleasant to drink. My wife also likes to use it at night for restless legs & to help relax. 😊
I love this product. I noticed an improvement in my skin. Looks and feels so much smoother.
I have systemic health issues and this is great for sleep, nerves and digestion (in a slow moving system). Great combination of types of magnesium. Easy to mix and take.
Great product. I take it every morning 🙂
Having parkinsons disease, exercise is very much my medication but has consequences the magnesium helps with the cramps and sleep quality which makes tomorrow better.
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
It’s one of those things that you don’t you don’t know what you’ve got ‘til it’s gone! I was sleeping well and didn’t notice my gym recovery was good until I ran out of magnesium! Without it, my sleep is terrible and I’m sore for days after working out. Ordering more now!
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.

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.
Imagine not thinking about
your eyes tomorrow.
No drops at your desk. No bottle in every bag.
No avoiding the things you used to enjoy.
Try it for 60 days. If your eyes don't feel different, you pay nothing.
