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.
Published in Nutrients by researchers from Karolinska Institutet and Uppsala University, the study tested Flexovital in a model of cardiovascular-kidney-metabolic (CKM) syndrome.
Measured in a preclinical model, not in people. Figures are from the published paper and describe the study, not what the product does for you.
Each capsule carries the same six compounds in the same proportions the study used. Three capsules a day is the full dose.
Amino acid that's directly converted into nitric oxide by endothelial cells lining your blood vessels. The body's most fundamental NO substrate.
Converts to L-arginine in the kidneys for longer-lasting NO production than arginine alone. Bypasses gut metabolism for better bioavailability.
Nordic adaptogen used for centuries to support stamina and stress resilience. Researchers identified potential PDE5-inhibitory effects supporting vasodilation.
Concentrated source of dietary nitrates that convert to nitric oxide via the nitrate-nitrite-NO pathway — a second route independent of L-arginine.
Essential mineral cofactor for vascular smooth muscle relaxation and over 300 enzymatic processes — including ATP production.
Antioxidant that protects nitric oxide from oxidative breakdown, extending its window of bioactivity in the vascular system.
The dose in one capsule is the dose the study used. The pouch prints three times that figure, because a daily dose is three capsules.
Three capsules is one daily dose — 550 mg of active formulation per capsule, 1,650 mg a day. One pouch holds 180 capsules, so it lasts 60 days. The study used a continuous daily dose over twelve weeks.
Nitric oxide isn't produced by one ingredient — it's a network. Flexovital activates two parallel pathways and protects the molecule once formed.
L-Arginine + L-Citrulline feed the eNOS enzyme in endothelial cells — the body's classical NO production pathway.
L-ARGININE → eNOS → NOBeetroot nitrates take a second pathway through saliva and gut bacteria — independent of arginine. Works even with reduced eNOS function.
NITRATE → NITRITE → NOVitamin C prevents oxidative breakdown of NO. Magnesium enables vascular relaxation. Rhodiola supports stress resilience.
PROTECT · RELAX · ADAPTFlexovital was developed by Bengt Fellström, professor of nephrology at Uppsala University and Akademiska sjukhuset. The study that later tested the complete formula was run by the nitric oxide research group at Karolinska Institutet, with Uppsala as co-authors.
Produced under strict Scandinavian quality controls. Every batch is fully traceable.
Developed by BioConcept AB around a formula from Bengt Fellström at Akademiska sjukhuset in Uppsala.
No proprietary blends. Exact dosages of every ingredient are disclosed in the peer-reviewed study.
Three capsules a day. Six ingredients. One formula, tested whole.
