Your blood
pressure reading
came back high.
This gives your body what it uses to relax and widen your blood vessels, and supports normal blood pressure.

Production peaks early in life and declines from there. Illustrative, not to scale.
Your blood vessels have stiffened and narrowed, so your heart has to push harder to move blood through them.
Nitric oxide is the molecule your body uses to tell those vessels to relax and widen. It's how your body keeps blood pressure in a healthy range.
You make less of it as you get older. Production peaks early in life and declines from there. Less nitric oxide, less of the signal telling your vessels to relax.
That last part is what the appointment usually skips.
More nitric oxide, a wider path, less resistance behind every heartbeat.
Biosphere Nitric Oxide supplies the raw materials your body uses to produce more of its own nitric oxide, so your vessels get more of the signal that relaxes them. That's the vessel function behind healthy blood pressure.
Nitric oxide doesn't stay in the body for long. That's why it's one scoop in the morning and one in the evening: two smaller doses keep it steady through the day instead of one spike that fades.
Twice a day, every day. That's the whole routine.
The piece that gets missed
Most people leave that appointment with a prescription, or a list of things to cut back on, and not much explanation of what's going on inside their blood vessels.
What you've probably been told
What none of them does
Every one of those takes load off the system, and they're worth doing. None of them restores the signal that tells your blood vessels to relax and widen, and that signal fades with age. That's the part this works on.
Keep doing the rest. Add this, and keep taking your readings.
What to expect
You don't rebuild nitric oxide levels overnight. One tub is 30 days at twice a day, and the guarantee runs for 60, so you get a fair test.
Weeks 1 to 2
Your body is getting the raw materials it has been short of. Nothing to feel yet for most people. Keep to morning and evening.
Weeks 2 to 4
This is when most customers notice steadier energy and better circulation: warmer hands and feet, less of a slump after activity.
Weeks 4 to 8
Research suggests this is the window for measurable blood pressure changes. Take your readings at the same time each day so you can see it.

Exactly what's in it
Six ingredients, each at a therapeutic dose, each covering a different part of how your body makes and keeps nitric oxide.
L-Citrulline Malate 2:1
2000mg
The main building block your body uses to make nitric oxide. Drives steady production through the day.
L-Arginine
1000mg
Converts directly to nitric oxide. Works with citrulline to produce it on demand.
Taurine
500mg
Supports the heart muscle and the electrolyte balance behind a healthy heart rhythm.
Hawthorn Berry Extract
500mg
A traditional cardiovascular herb that helps vessels relax and widen.
Vitamin C
300mg
Protects the nitric oxide you produce from breaking down too fast.
Vitamin D
200IU
Supports nitric oxide production in the vessel lining, the layer most involved in blood pressure.
Other ingredients: Stevia Leaf Extract, Inulin, Citric Acid, Silicon Dioxide, Natural Flavours, Calcium Silicate, Annatto Seed Powder (for colour). Naturally sweetened. Vegetarian and vegan friendly.
The clearest sign a supplement is doing something is whether people buy it again. Then read what they say.
Made in a GMP-certified facility. Third-party tested every batch.
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.
This one is formulated to a result. Every ingredient at a therapeutic dose, every dose printed on the label, and every batch tested by an independent lab before it ships.
It costs more than a tub of citrulline pills. It should . It's a different product.

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.
What people ask before they try it.
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.
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.
Because it clears from the body within hours. One large daily dose creates a brief spike followed by a long trough. 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.
Yes. The ingredients are non-habit forming and well-researched for daily use. Most customers take it as part of their ongoing daily routine.


One tub is a month at twice a day. If it does nothing for you inside 60 days, you get your money back.
"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."
