CARDIOVASCULAR HEALTH & NITRIC OXIDE BIOLOGY
Vascular Elasticity & Nitric Oxide Decline After 40: Cellular Oxygen Delivery
In human physiology, vascular health and physical capacity are directly tied to the body's ability to synthesize Nitric Oxide (NO). As the body ages, endothelial NO synthesis naturally decelerates. OXIFIT is engineered to restore clinical nitric oxide synthesis and vascular dilation (vasodilation).
40+
Up to 50% NO Loss After Age 40
Clinical research (PubMed / PubChem lit.) demonstrates that starting at age 40, endothelial eNOS enzyme activity decreases, causing up to a 50% drop in nitric oxide production compared to age 20. This leads to vascular stiffness, reduced tissue nourishment, and premature fatigue.
NO
Vascular Dilation & Smooth Circulation
Nitric Oxide triggers smooth muscle relaxation along blood vessel walls, causing natural vasodilation. Expanded vessel diameters enhance microcirculation, lower peripheral resistance, and ease cardiac burden for cardiovascular protection.
O₂
Cellular Oxygen & Nutrient Delivery
Expanded microvascular pathways allow red blood cells to deliver maximum oxygen volume to working muscle fibers. Increased tissue oxygenation delays lactic acid accumulation, lowers muscle soreness, and elevates VO2 Max capacity.
Cardiovascular Heart Health & Pine Bark Synergy
OXIFIT combines Baltic Maritime Pine Bark (Pinus Pinaster) with Red Beetroot Nitrate to optimize cardiovascular heart health and arterial elasticity. This clinical synergy supports blood pressure balance and eNOS signaling—reducing cardiac workload while delivering caffeine-free cardiovascular protection.

Nitric Oxide (NO) is a vital molecule naturally produced in our body that enables "cellular communication". Its primary task is vasodilation, i.e., widening of blood vessels.
Beetroot in our formula contains high levels of natural Nitrate (NO₃). When ingested, these nitrates convert first to Nitrite (NO₂) and then to Nitric Oxide (NO) in the bloodstream, optimizing blood flow.

Step 1SalivaryNO₂ (Nitrite)

Step 2Blood StreamNO (Nitric Oxide)

ResultVasodilationIncreased Blood Flow
Result: More oxygen, more nutrients, and higher performance for muscles and brain.
Beetroot is nature's richest and most bioavailable source of nitrates. Unlike synthetic "Pre-workout" products, beetroot supports the body's natural production mechanisms.
Natural Absorption
Recognized and processed by the body with zero risk of side effects.
Antioxidant Support
Contains betalains providing cellular protection in addition to nitrates.
This formula is not just for professional athletes, but for anyone looking to optimize their circulatory system:
- Athletes: To increase stamina and maximize the "pump" effect.
- Active Professionals: To support cognitive focus by increasing oxygen delivery to the brain.
- Circulation Seekers: For those wishing to naturally balance blood flow and pressure.
Nitric oxide levels in the blood peak 45-60 minutes after consumption. Therefore, taking it about an hour before workouts or intense mental activity provides maximum efficiency.
Being 100% natural, it has no known harmful side effects. However, due to beetroot's natural pigments (betalain), a pinkish/reddish discoloration in urine or stool (Beeturia) may occur.
This is completely harmless and is proof of the natural, high-concentration beetroot content. You can balance this by increasing your water intake.
Pure beetroot extract has a characteristic "earthy" taste. However, our formula is optimized with natural flavors to balance the taste and make it enjoyable to drink, with no artificial sweetness.
You can pay securely with PayTR 3D Secure infrastructure. Your orders are prepared on the same day and shipped with free delivery to all provinces of Turkey.
