01
As blood pressure rises, it typically traces to this: your blood vessels have stiffened and narrowed, so your heart has to push harder to move blood through them.
02
Nitric oxide is the molecule your body uses to tell those vessels to relax and widen, which is how it keeps blood pressure in a healthy range.
03
Your body’s nitric oxide production peaks early in life and declines from there. Less nitric oxide means less of that natural signal telling your vessels to relax.
Nitric oxide your body makes, by age
04
Biosphere Nitric Oxide supplies the raw materials your body uses to produce more of its own nitric oxide, supporting the vessel function behind healthy blood pressure.
Verified Nitric Oxide review
★★★★★
"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."

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 :)
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.
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.
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.
Six clinically dosed ingredients. Therapeutic amounts of each. Made in a GMP-certified facility. Third-party tested every batch. No fillers. No corner-cutting.
It costs more than a tub of citrulline pills. It should. It’s a different product.
Every order comes with a 30-serve tub of Biosphere Magnesium, worth $42.99. It isn’t a random throw-in. Magnesium is one of the minerals your cardiovascular system relies on most, and it’s commonly low in modern diets. Here’s why the pair makes sense.
Biosphere Magnesium · 400mg elemental magnesium per scoop · 30 servings · Mango Pineapple
Take it for 60 days. If you’re not feeling steadier energy, better circulation, or improved blood pressure readings, get every dollar back. No questions, no hoops to jump through.
Refund processed promptly via the original payment method.
On medication? Here’s what people ask before they order.
Yes, many customers use Biosphere Nitric Oxide alongside their medication.
Make sure to keep an eye on your blood pressure as they both work in the same direction.
If you are taking medication, it is always a good idea to consult with your doctor and let them know what supplements you’re adding.
Most people notice steadier energy and better circulation within 2 to 4 weeks of consistent use. Blood pressure changes typically take longer: research suggests 4 weeks for measurable improvements. Like all supplements, it works best when taken consistently as directed (twice daily, before meals).
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.
Add Nitric Oxide to your cart and a 30-serve tub of Biosphere Magnesium (Mango Pineapple) is added to your order at no charge. You’ll see both in your cart before you pay. One free tub per order, while stocks last.
Yes. The ingredients are non-habit forming and well-researched for daily use. Most customers take it as part of their ongoing daily routine.
