Performance starts with blood flow
The artery that gets you hard is one to two millimetres wide, the narrowest you own. That's why trouble with blood flow tends to show up there first.
This stack works on it from two sides, every day:
- CardioFlow clears the road. 10,800 FU nattokinase supports healthy blood flow and normal fibrin balance. K2 (MK-7) supports flexible arteries.*
- Nitric Oxide Boost opens the lanes. L-arginine and beetroot nitrates give your body what it uses to make nitric oxide, which helps blood vessels relax and widen.*
Two steps. Under 10 seconds.
No planning your night around a pill. Take CardioFlow with breakfast and Nitric Oxide Boost before a workout or in the afternoon. Consistency is what builds results.

TRY IT RISK-FREEQuestions men ask
What's in each kit?
One pouch of CardioFlow Nattokinase + K2 (30 softgels) and one pouch of Nitric Oxide Boost (60 capsules), about a month's supply of each.
Why take both together?
They do different jobs. CardioFlow supports healthy blood flow and flexible arteries. Nitric Oxide Boost gives your body the raw materials to make nitric oxide, which helps blood vessels relax and widen. Together they support blood flow from two directions.*
Will this help with my erections?
Firm erections depend on healthy blood flow. This stack supports healthy blood flow and nitric oxide production every day. It is not a drug and does not work like one. Every man is different, so take it daily and give it the full 90 days.*
How do I take it?
2 CardioFlow softgels in the morning with water and food, and 2 Nitric Oxide Boost capsules in the afternoon or before a workout.
I take Viagra, Cialis or blood pressure medication. Can I take this?
Talk to your doctor first. L-arginine and beetroot can lower blood pressure, and combining them with ED medication, nitrates or blood pressure medication may lower it too far. Never stop or change a prescribed medication on your own.
Who should check with a doctor first?
Anyone who takes warfarin, Eliquis, Xarelto, Plavix, daily aspirin or other blood thinners, blood pressure medication or nitrates, has surgery coming up, has a bleeding disorder or low blood pressure, or has a heart condition. CardioFlow contains soy.
How long until I notice a difference?
Some men notice the nitric oxide "pump" during workouts within the first weeks. Blood-flow support builds with steady use, so we recommend the full 90 days.*
How does the subscription work?
Your order refills every 4 weeks. You can skip, pause or cancel anytime. Free bonus guides ship with your first order only.
What if it's not for me?
You're covered by our 90-day money-back guarantee. Contact us and we'll refund you.
