Nitric Oxide
1 Tub

Support for your whole cardiovascular system.
Nitric oxide is what lets your blood vessels relax and widen. Support how your body makes it, and you support the system that depends on it.
-
Healthy blood pressure
The reason most people start. Nitric oxide is the signal that tells your vessel walls to relax, so the vessel widens and blood moves with less resistance behind it.
This supports your body making its own, rather than acting on the reading directly. It belongs alongside prescribed medication, not instead of it.
Circulation usually shifts in 2 to 4 weeks. Research suggests blood pressure takes 4 to 8 weeks.
-
Circulation and blood flow
Supports steady blood flow to the muscles, the hands and feet, and everywhere else it needs to reach.
-
Cardiovascular support
Taurine, hawthorn and vitamin D support the heart muscle and the vessels around it.
-
Steadier energy
Better circulation moves oxygen and nutrients more efficiently, which supports day-to-day energy.
-
Two precursors, not one
Citrulline raises the baseline your body works from, arginine produces on demand. Running both is what keeps nitric oxide steady through the day rather than spiking and fading.
Inside every scoop
Therapeutic doses, every serve
Six ingredients. One cardiovascular pathway.
Each one supports a different part of how your body makes and uses nitric oxide, dosed at a level that actually does the job.
-
2000 mg
L-Citrulline Malate 2:1
The primary nitric oxide precursor. It converts to arginine, then to nitric oxide, driving sustained production through the day. The malate supports cellular energy.
-
1000 mg
L-Arginine
A direct nitric oxide precursor. Stacked with citrulline, the two work in tandem: citrulline raises the baseline, arginine produces nitric oxide on demand.
-
500 mg
Taurine
Supports the heart muscle's ability to contract efficiently, and helps regulate the electrolyte balance behind a healthy heart rhythm.
-
500 mg
Hawthorn Berry Extract
Used as a cardiovascular remedy for centuries. Its antioxidants aid nitric oxide production and act directly as a vasodilator, helping vessels relax and widen.
-
300 mg
Vitamin C
Protects nitric oxide from oxidising too quickly, keeping more of it active in the bloodstream where it supports vasodilation.
-
200 IU
Vitamin D
Enhances nitric oxide production in the vessel lining, the layer most directly involved in blood pressure. Deficiency is increasingly common in NZ.
Six actives at therapeutic dosesOne scoop, twice a day

- One scoop, morning Mix a 6.5g scoop into 200ml of water, before a meal.

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!
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.
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!
Perfect start to my day…great flavour and definitely an improvement showing in my blood pressure levels!
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
I have this in the morning. Great tasting and refreshing. Great start to the day
I can see a great change in my daily routine after start using nitric oxide every day in the morning feeling fresh and do my day to day work with out any tiredness ,I strongly recommend it.
Absolutely love this stuff! Keeps my blood pressure in check. I don't need prescribed medication at the moment which I'm most grateful for, as it made me feel dreadful. This makes me feel great!
I sort of decided to try this product on a whim but very pleased that I did. My Optometrist, at my recent annual checkup, was very pleased to inform me that the pressure in my eyes has decreased markedly where it had been increasing year on year prior to using Nitric Oxide. My BP is also stable at a normal level now too. I am now a repeat and regular customer of Nitric Oxide.
So good, a changing to a subscription. Tastes wonderful.
Taste good and not hard to drink
As a hot drink
We love nitric oxide 1st thing in the morning.😃
Seems to be helping keep my blood pressure in check👍
Great taste, good decision to buy
The BP results speak volumes
I really like he flavour it’s so easy to drink
My second purchase thus far. Im loving this stuff, tastes good and helps replenish my body of all the good stuff I need.
This product lifts you up and seems to have a positive effect on your B/P and general well being. However it must be used in conjunction with the normal sidekicks of exercise and awareness of diet. It is no "Magic Bullet" alone, but it does help.
Great taste! Refreshing, hydrating and energising in the morning! Brilliant , well researched product.
I use both the Nitric Oxide and the Magnesium! At 73 years of age, I need the heart, blood, and muscle support the these products bring. I still work hard physically, and I can really tell the difference since I’ve been using them! Thanks for providing such a great product!! Steve - Russell, New Zealand
This is such a great product, since I have been taking it I have a lot more energy when I am working out, and day to day chores. I also love the Sleep formula too! Thanks Biosphere
Love the taste and it’s really helped bring down my BP
Using the magnesium and nitric oxide for a couple of years now after my nutritionist introduced me to the produce. My blood pressure well under control.

Tasty drink - I find it a refreshing way to start the day
I use this product on a daily basis to promote vascularization and combine it with marine collagen, and rapeseed oil (1/2 tbs). It's a good early morning routine and in the evenings I often combine it with flavoured magnesium powder.
Great product ..And yes it works 100% Very happy ,Will keep buying this..

These products have been an important part of my health journey of weight loss, high blood pressure... Thanks...
Questions, answered honestly
Everything you need to feel confident before you try it.
How fast will I notice a difference?
Steadier energy and better circulation usually take 2 to 4 weeks of consistent use. Blood pressure changes typically take longer: research suggests 4 to 8 weeks for measurable improvements. Like all supplements, it works best when taken consistently as directed, twice daily, 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.
Why two doses a day?
Nitric oxide doesn't stay in your body for long. One large daily dose creates a brief spike followed by hours of low levels. Two smaller doses, morning and evening, support steadier nitric oxide availability throughout the day. That's the level of support your cardiovascular system actually benefits from.
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?
Naturally flavoured peach mango, sweetened with stevia. No artificial sweeteners, no synthetic flavours. Most customers describe it as pleasant enough to look forward to as a daily ritual.
How does the 60-day money-back guarantee work?
Take it for up to 60 days. If you are not feeling steadier energy, better circulation, or better blood pressure readings, email us and we will refund your order. No need to return the tub, with next-day Auckland dispatch on every order.
