A problem has been put in front of you. So you're going to deal with it.

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.

The reason has a name. You've probably never heard of it.
WHY THE NUMBER WENT UP

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 FORMULA

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 Precursor
    2000mg
    L-Citrulline Malate

    Converts to arginine, then to nitric oxide. Drives sustained production throughout the day.

  • Direct Precursor
    1000mg
    L-Arginine

    Direct nitric oxide precursor. Stacked with citrulline so the two work in tandem.

  • Heart Muscle
    500mg
    Taurine

    Supports heart muscle contractility and the electrolyte balance critical for healthy rhythm.

  • 500mg
    Hawthorn Berry Extract

    A natural vasodilator. Used in herbal cardiovascular medicine for centuries.

  • 300mg
    Vitamin C

    Protects nitric oxide from breaking down too quickly in the bloodstream.

  • 200IU
    Vitamin 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 photo review of Astaxanthin

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.

Customer photo review of Sleep

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

Customer photo review of Nitric Oxide

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.

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!

Customer photo review of Sleep

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.

Astaxanthin

Customer photo review of Astaxanthin

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.

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?

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.

Where does this ship from?

All Biosphere orders ship from our Auckland warehouse. Most orders are dispatched the next business day, with delivery to most parts of New Zealand within 1 to 3 working days from dispatch.
