Vatellia Life

Vatellia Life Nitric Boost - Nitric Oxide Supplement for Men | High Absorption Formula | 100% Natural Ingredients | Best Nitric Oxide Booster | Increase Blood Flow | 2 Month Supply

Free Shipping

Main Highlights

HOW NITRIC OXIDE SUPPLEMENTS WORK: Nitric oxide supplements dont contain nitric oxide itself. However, they contain natural compounds (pre-cursors) your body uses to make nitric oxide. Since your body's ability to produce nitric oxide declines with age, nitric oxide supplements help offset the decline. Users typically report feeling its effects in the first few days, as blood vessels widen & circulation improves throughout the entire body.
WHY CHOOSE VATELLIA LIFE NITRIC BOOST? Most nitric oxide supplements rely on the amino acid arginine to stimulate nitric oxide production. However, our Nitric Boost formulation utilizes its counterpart citrulline, which is known for its superior bioavailability (absorption rate) compared to arginine. We also provide a 2-month supply of capsules per bottle, whereas most nitric oxide bottles contain a 1-month supply. This is why our price per bottle is higher.
HEALTH BENEFITS: Optimal nitric oxide levels in the body have been shown to support healthy blood pressure, energy, brain function, immune response, exercise recovery & longevity. Nitric oxide is also known for its positive impact on male "performance" because it increases blood flow to all extremities. This is why nitric oxide was declared "The Miracle Molecule" after its discovery in 1998, which was awarded a Nobel prize.
USA REGULATED QUALITY/SAFETY: Nitric Boost is proudly manufactured in the USA in an FDA registered GMP certified laboratory. All ingredients are 100% natural, stimulant-free, non-GMO and free of harmful additives & fillers. Our capsules are continually tested by a third party to assure quality & purity. Nitric oxide supplements containing l-citrulline are generally considered safe for most people when used in appropriate doses.
