Six ingredients.
One proven formula.
Every capsule contains six carefully selected compounds — each chosen for its role in nitric oxide production, circulation, or cellular vitality. Not as isolated ingredients, but as a peer-reviewed formula.
The full Flexovital formula was studied —
not just the ingredients.
Published in Nutrients by researchers from Karolinska Institutet and Uppsala University, the study tested Flexovital in a model of cardiovascular-kidney-metabolic (CKM) syndrome.
Every ingredient,
precisely dosed.
Each capsule delivers a carefully calibrated dose of six active compounds. Take 3–4 capsules daily for the full protocol.
L-Arginine
Amino acid that's directly converted into nitric oxide by endothelial cells lining your blood vessels. The body's most fundamental NO substrate.
L-Citrulline
Converts to L-arginine in the kidneys for longer-lasting NO production than arginine alone. Bypasses gut metabolism for better bioavailability.
Rhodiola Rosea
Nordic adaptogen used for centuries to support stamina and stress resilience. Researchers identified potential PDE5-inhibitory effects supporting vasodilation.
Beetroot Extract
Concentrated source of dietary nitrates that convert to nitric oxide via the nitrate-nitrite-NO pathway — a second route independent of L-arginine.
Magnesium Citrate
Essential mineral cofactor for vascular smooth muscle relaxation and over 300 enzymatic processes — including ATP production.
Vitamin C
Antioxidant that protects nitric oxide from oxidative breakdown, extending its window of bioactivity in the vascular system.
Why this exact
combination?
Nitric oxide isn't produced by one ingredient — it's a network. Flexovital activates two parallel pathways and protects the molecule once formed.
Direct synthesis
L-Arginine + L-Citrulline feed the eNOS enzyme in endothelial cells — the body's classical NO production pathway.
Nitrate reduction
Beetroot nitrates take a second pathway through saliva and gut bacteria — independent of arginine. Works even with reduced eNOS function.
Protection & support
Vitamin C prevents oxidative breakdown of NO. Magnesium enables vascular relaxation. Rhodiola supports stress resilience.
