Why blood pressure climbs with age, and how to bring it back to normal.
01
Stiffer blood vessels make your heart push harder.
Healthy blood vessels stretch with every heartbeat. With age they stiffen and narrow, like an old garden hose, so your heart has to push harder to move the same blood. That extra push is what shows up in your reading.
02
Nitric oxide is the signal that relaxes and widens them.
Nitric oxide is a molecule your body makes to tell your vessel walls to relax and widen, so blood moves through with less pressure. Its role in your blood vessels won the 1998 Nobel Prize in Medicine.
03
Your body makes less of it every year after your thirties.
Production peaks early in life and declines from there. Less nitric oxide means less of the signal telling your vessels to relax, and it’s one reason readings tend to creep up from your fifties.
Nitric oxide your body makes, by age
Illustrative, not to scale.
04
Low nitric oxide shows up in more than your reading.
Nitric oxide opens blood vessels all through your body, not just the ones behind your blood pressure. When it runs low, men commonly notice:
Cold hands and feet
Getting puffed on hills and stairs that used to be easy
Less energy by the afternoon
Things not working like they used to in the bedroom
If a few of those sound familiar, it’s the same signal running low.
05
Biosphere Nitric Oxide helps your body make more.
Its lead ingredient is L-citrulline, which your body converts to arginine and then to nitric oxide. It leads the formula because it has the most research behind it, and it’s here at a therapeutic dose.
Your prescription works on the reading. This works on one of the reasons it climbed.
On blood pressure medication?
Yes, many customers take it 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’s always a good idea to consult your doctor and let them know what supplements you’re adding.

"I have been using Nitric Oxide for a few months now and a resent visit to my Doctor to check blood pressure was the best it has been for a very long time. So will continue to use the product on going."

"Haven’t checked blood pressure, but I’m feeling fitter, stronger and more energetic. After 3 weeks, this septuagenarian is at least 10 years younger. Long may it continue!"

Walks get easier
★★★★
"It’s probably a bit too early to comment favourably but already I’ve noticed that I have a little more energy when I used to go for a 2 km walk I would have to sit and rest 4 times. Recently since taking nitric oxide, I have found it only had to sit and rest twice and more recently once on the 2 km walk"

"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."

Before you order
What people ask before they order.
Can I take this with my blood pressure medication?
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.
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 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).
How does the free Magnesium work?
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.
Is it safe to take long-term?
Yes. The ingredients are non-habit forming and well-researched for daily use. Most customers take it as part of their ongoing daily routine.

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.
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
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.
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 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.
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.
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!
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
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.
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.
