🍉
Nitric-oxide precursor

L-Citrulline

An amino acid your body converts into L-Arginine and then nitric oxide, the molecule that tells blood vessels to relax and widen for healthy circulation.

🌲
Antioxidant & eNOS support

Pine Bark Extract

Rich in proanthocyanidins, this French maritime pine extract supports your body's own nitric-oxide enzyme and provides antioxidant protection for blood vessels.

🍊
Collagen & vessel support

Vitamin C

Supports collagen production for strong, flexible arterial walls and provides antioxidant support for healthy circulation.

🥪
Arterial connective tissue

L-Lysine

An essential amino acid that works alongside Vitamin C to support the connective tissue that keeps artery walls resilient.

🪨
Smooth-muscle relaxation

Magnesium

An essential mineral that supports the relaxation of the smooth muscle in blood vessel walls, helping circulation stay smooth and steady.

🥚
Arterial calcium balance

Vitamin K2

The MK-7 form supports healthy calcium metabolism, helping keep calcium in bones and out of arteries for long-term vascular wellness.

💧
Healthy blood flow

Nattokinase

A traditional enzyme derived from fermented soy that supports healthy blood viscosity, so blood keeps flowing freely through your vessels.

How the formula is put together

Boostaro combines its seven ingredients in a once-daily two-capsule serving. Exact per-ingredient amounts are formulated as a proprietary blend on the retail label rather than listed individually, which is common for blood-flow formulas — what matters is that the seven ingredients are all clinically studied for circulation and cardiovascular support.

Other ingredients

A plant-based vegetarian capsule with clean, non-GMO ingredients. Serving size 2 capsules · 30 servings per bottle. No caffeine and no stimulants, made in a GMP-certified US facility.

What the research says

L-Citrulline, Pine Bark Extract, Vitamin C, Vitamin K, Magnesium and nitric-oxide support are among the most-studied areas in vascular wellness. Our references section links to Mayo Clinic and the NIH Office of Dietary Supplements so you can read the science yourself.
