FOR PEOPLE TAKING THEIR BLOOD PRESSURE SERIOUSLY
4.7/5 stars from 200 verified reviews
4 things to know about your blood pressure and nitric oxide.
- 60-day money-back guarantee
- Third-party lab tested
01.
Nitric oxide is the molecule that tells your blood vessels to relax.
It's a tiny molecule that signals the inside of your blood vessels to relax. Vessels relax, blood moves through with less resistance, the number on the cuff goes down.
The inner lining of your blood vessels makes nitric oxide on its own. It releases it minute by minute, in response to what your body is doing.
02.
Your body makes less nitric oxide every year of your adult life.
Production peaks in your twenties. From there it drops, year after year. By your sixties, levels can be half of what they were in your prime.
Less nitric oxide means stiffer, narrower vessels. Less room for the same volume of blood. Your heart works harder. The number goes up.
This isn't something you did wrong. It's part of how the body ages.
03.
Nitric oxide doesn't only support blood pressure. It supports everything that depends on blood flow.
Your heart works easier when vessels relax. Your brain gets more oxygen when blood moves freely. Your hands and feet stay warmer. You recover from exertion faster. The fog after a heavy meal lifts sooner.
Blood pressure is the most measurable benefit. It's not the only one.
04.
Your body uses specific building blocks to make nitric oxide. You can give it more of them.
Some of those building blocks you can get from food. Beetroot, leafy greens, citrus. Exercise helps too, by stimulating the lining of your vessels.
What food can't reliably deliver is the clinical doses. The amounts research has tied to actual changes in nitric oxide production. That's where supplementation comes in.
What proper nitric oxide support actually looks like.
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.
What makes this one different:

The strongest signal a supplement is doing something isn't a review. It's a reorder.

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.

If you're going to do this, do it properly. Throw everything at it.
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.
- No questions asked
- No need to return the tub
- Refund processed promptly via the original payment method
Questions worth asking before you start.
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.
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 to 8 weeks for measurable improvements. Like all supplements, it works best when taken consistently as directed (twice daily, before meals).
