Your blood pressure
reading came back high.
There's a molecule that controls how easily blood moves through your body. Your body makes less of it every year.

A problem has been put in front of you. So you're going to deal with it.
The diagnosis didn't come out of nowhere. The stress, the years, the diet that slipped, the workouts that stopped. None of it was deliberate. All of it added up.
What you don't want is a lifetime on pills. What you do want is to take this seriously, do the work, and bring the number down the way it went up. Slowly. Properly. Without ignoring what the doctor said.
We're going to skip the part where we tell you to relax. What we want to show you is something you've probably never heard of, that works alongside everything else you're already doing. Something your body has been making less of every year of your adult life.
WHY THE NUMBER WENT UPThe reason has a name.
The reason has a name.
You've probably never heard of it.
It's called nitric oxide. A molecule your body makes naturally. Its job is to tell your blood vessels to relax and widen, so blood moves through with less pressure.
Your body has been making less of it every year of your adult life. Less nitric oxide means stiffer, narrower vessels. Less room for the same volume of blood. The number goes up.
That's not something you did wrong. It's something your body does less of as you get older. The fix isn't to fight it. The fix is to support it.
MEET THE FORMULASix ingredients at therapeutic doses.
Six ingredients at therapeutic doses.
One job.
Six ingredients. Each chosen for a specific job in your cardiovascular system. Each at the dose used in clinical studies, where it actually showed a measurable effect. All printed on the label. Nothing hidden in a 'proprietary blend.'
- Primary Precursor2000mgL-Citrulline Malate
Converts to arginine, then to nitric oxide. Drives sustained production throughout the day.
- Direct Precursor1000mgL-Arginine
Direct nitric oxide precursor. Stacked with citrulline so the two work in tandem.
- Heart Muscle500mgTaurine
Supports heart muscle contractility and the electrolyte balance critical for healthy rhythm.
- 500mgHawthorn Berry Extract
A natural vasodilator. Used in herbal cardiovascular medicine for centuries.
- 300mgVitamin C
Protects nitric oxide from breaking down too quickly in the bloodstream.
- 200IUVitamin D
Enhances nitric oxide production in the inner lining of blood vessels.
Six ingredients at clinical-study doses. There are cheaper nitric oxide products in NZ. There are reasons they're cheaper.
WHY WE MADE IT THIS WAY
The supplement industry runs on cheap forms, fractional doses, and good marketing.
Most products are formulated to a price point, not to a result. That's why most people don't feel anything when they take them.

Customer Reviews
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.

COMMON QUESTIONS
What people ask before they try it.
How fast will I notice a difference?
Most people notice steadier energy and better circulation within 2 to 4 weeks of consistent use. Blood pressure changes take longer to register and depend on your starting point. Research suggests 4 to 8 weeks of consistent twice-daily use before changes typically become measurable. It works best when taken every day as directed, before meals.
Can I take this with my blood pressure medication?
If you are on prescribed blood pressure medication, please consult your GP before adding any supplement to your routine. Many customers use Biosphere Nitric Oxide alongside their medications with medical supervision, but a quick conversation with your doctor first is always the right call.
Is it safe to take long-term?
Yes. The ingredients are non-habit forming and well-researched for daily use. 72% of our customers reorder within 90 days, which suggests they are comfortable taking it as part of their ongoing daily routine.
How does it taste?

Where does this ship from?
