L-Citrulline
An amino acid that the body converts into L-Arginine, which is then used to produce nitric oxide. Higher nitric oxide levels relax blood vessels and improve circulation. Multiple peer-reviewed studies confirm L-Citrulline supplementation supports healthy blood flow and male wellness.
Pine Bark Extract (95% Proanthocyanidins)
A powerful plant antioxidant that protects blood vessel walls and reduces oxidative stress. Pine Bark Extract has been clinically studied for its synergistic effect with L-Citrulline in supporting male vascular wellness when combined in supplementation.
Vitamin C (Ascorbic Acid) — 500mg
An essential antioxidant that enhances L-Citrulline absorption, protects blood vessels from oxidative damage, and supports collagen formation in arterial walls. Boostaro includes a therapeutic 500mg dose per serving — far above standard multivitamin levels.
Vitamin K2 (Menaquinone) — 100mcg
Supports calcium metabolism and arterial flexibility. Clinical research demonstrates that K2 supplementation supports arterial health — a direct contributor to better circulation. Vitamin K2 also works synergistically with Vitamin D for bone and cardiovascular wellness.
L-Lysine HCL
An essential amino acid the body cannot produce on its own. L-Lysine plays a critical role in collagen synthesis — the structural protein that keeps blood vessels strong and flexible. Essential for cardiovascular health and tissue repair.
L-Proline
Another essential amino acid that supports collagen synthesis alongside L-Lysine. Together, these two amino acids help maintain the structural integrity of arterial walls — supporting both blood vessel strength and elasticity for sustained vascular performance.
Magnesium Citrate
Magnesium deficiency is clinically linked to low energy and poor circulation. Magnesium Citrate is the most bioavailable form, supporting muscle function, nerve health, hormonal balance, and over 300 enzymatic reactions in the body.
Nattokinase
A natural enzyme derived from fermented soy that supports healthy blood viscosity and circulation. Nattokinase promotes smooth blood flow and supports cardiovascular wellness — making it an important contributor to the Boostaro formula's overall vascular support.
The Boostaro formula stands apart from generic men's wellness supplements for several reasons:
