The Problem
You're exhausted. But your body won't let you sleep.
You get into bed tired. Genuinely tired. But the moment your head hits the pillow, something shifts. Your mind starts racing. Your shoulders tighten. Sleep feels close but never quite arrives.
Some nights you drift off eventually. Others, you wake at 2am staring at the ceiling, already dreading how tomorrow will feel.
The next day is a fog. You're short with the kids. You can't focus at work. You're running on caffeine and willpower, and both are running out.
You've tried things. Herbal teas. Melatonin gummies. Going to bed earlier. Cutting caffeine after lunch. Some helped a little. Nothing lasted.
Here's why:Most of those approaches treat the symptoms. They don't address why your body can't switch off in the first place.

How Biosphere Sleep Works With Your Body
A 3-phase system with powerful ingredients targeting the root cause of poor sleep
A 3-phase system designed to work with your natural sleep cycle.
Biosphere Sleep doesn't sedate you. It doesn't knock you out. It gives your body the raw materials it needs to do what it already knows how to do.
Ten ingredients. Three phases. Each one targeting a specific reason you can't sleep.
Biosphere Sleep doesn't sedate you. It doesn't knock you out. It gives your body the raw materials it needs to do what it already knows how to do.
Ten ingredients. Three phases. Each one targeting a specific reason you can't sleep.
Your stress hormones are too high. Your brain won't switch off. You're physically tired but mentally wired.
Ashwagandha (500mg) lowers cortisol, your primary stress hormones. L-Theanine (200mg) increases alpha brain waves, the calm-but-alert state you feel after a long walk. Lemon Balm (100mg) quiets mental restlessness.
What you'll feel: Your shoulders drop. Your jaw unclenches. The mental chatter starts to fade.
Phase 1
(First 30 minutes)
Your body temperature needs to drop slightly before sleep can begin. That's the biological trigger most people don't know about.
L-Glycine (2000mg) lowers your core temperature, signaling your body that it's time to sleep. L-Tryptophan (300mg) converts to serotonin, then melatonin, your body's own sleep hormone. Jujube Fruit (200mg) and Apigenin from Chamomile (5mg) promote relaxation without sedation.
What you'll feel: Your eyelids get heavy. Yawning starts. You drift off without forcing it.
Phase 2
(30 to 60 minutes)
Falling asleep is only half the problem. Staying asleep is the other half.
Magnesium Bisglycinate (100mg) activates GABA receptors, your brain's natural "off" switch, and relaxes muscles. Zinc Bisglycinate (15mg) regulates your circadian rhythm. Hops Flower (200mg) reduces nighttime awakenings and increases total sleep time.
What you'll feel: No 3am wake-ups. No tossing. You sleep through and wake when your alarm goes off, feeling like you actually rested.
Phase 3
(Through the Night)

10 ingredients at therapeutic doses
Works with your natural sleep cycle
Most sleep supplements are underdosed. This one isn't.
Based on commonly available sleep supplements. Individual products vary.
Here's something worth knowing before you buy any sleep supplement:
Most brands use the right ingredients. But they use a fraction of the dose that research says actually works. It's like taking one sip of coffee and expecting to wake up. The ingredient is there. The amount is useless.
Biosphere Sleep uses the exact therapeutic amounts from peer-reviewed research. Every ingredient. No proprietary blends. No shortcuts.
Third-party lab tested. GMP certified. Full label transparency.
We're not the cheapest sleep supplement you can buy. We're the one that works.

One Scoop. One Minute. That's It.
No pills to swallow. No complicated bedtime routine.
- 1 Mix 1 scoop into a glass of water.
- 2 Sip it 60 minutes before bed.
- 3 Let the 3-phase system do the rest.
Naturally flavoured with passionfruit, sweetened with a dash of stevia and monk fruit extract. No chalky aftertaste. Most customers look forward to their nightly serve.
Why powder, not capsules?
10 therapeutic-dose ingredients can't fit in a capsule. A typical capsule holds 600–700mg. Our scoop is 6.3g total. To match one serving you'd need roughly 10 capsules every night.
We made it a powder so you get everything in one go. Faster absorption, no handful of pills, and a ritual you'll actually look forward to

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.
Better Sleep Changes Everything.
Better sleep isn't just about feeling rested. Our customers regularly tell us about changes they didn't expect.
Your relationships improve.
You're present. You're patient. You're not snapping at people because you're half-asleep and grumpy at everyone.
Your work sharpens.
You're focused in meetings. You remember things. No more re-reading the same email five times.
Your mood stabilises.
No more afternoon crashes. No more anxiety spirals. No more barely holding it together by 4pm.
I am seeing results on nightly sleep monitoring of between 30–45 mins extra deep and REM sleep. Absolutely makes the day a lot easier to manage!
Have struggled with sleep through menopause and this has really helped
Gives me a great sleep and no more muscle cramps
