What's Inside Boostaro
Seven clean, clinically studied ingredients — no proprietary-blend smoke and mirrors. Here's exactly what each one does.
Boostaro keeps its label honest: plant-based, non-GMO ingredients chosen for how they support nitric oxide, healthy circulation and vascular health. Below is the full breakdown of the core formula.
| Ingredient | Primary role |
|---|---|
| L-Citrulline | Nitric oxide precursor — converts to L-Arginine, then nitric oxide, to help relax and widen blood vessels for healthy circulation. |
| Pine Bark Extract | French maritime pine antioxidants (proanthocyanidins) that work in synergy with L-Citrulline and help protect nitric oxide from breakdown. |
| Vitamin C | Shields nitric oxide from free radicals and supports collagen for strong, flexible artery walls. |
| L-Lysine | Essential amino acid that, paired with Vitamin C, supports clear, healthy arteries. |
| Magnesium | Essential mineral involved in healthy blood vessel function and normal energy metabolism. |
| Vitamin K2 | Helps direct calcium to bones and away from arteries, supporting flexible vessels. |
| Nattokinase | Natural enzyme traditionally used to support smooth, healthy blood flow. |
L-Citrulline — the cornerstone
Everything starts here. L-Citrulline is the amino acid that fuels the nitric oxide pathway. Because it converts to L-Arginine after passing the liver, it raises arginine levels more effectively than L-Arginine taken on its own. More arginine means more raw material for nitric oxide — the molecule healthy blood flow depends on.
Pine Bark Extract — the protector
Sourced from the French maritime pine and often known by the trademarked name Pycnogenol, Pine Bark Extract is packed with proanthocyanidin antioxidants. While L-Citrulline helps produce nitric oxide, Pine Bark helps preserve it by neutralizing the free radicals that would otherwise break it down. The two together are a classic circulation-support pairing.
Vitamin C & L-Lysine — the artery team
Vitamin C is far more than an immune nutrient here. It protects nitric oxide from oxidation and is essential for collagen — the protein that gives blood vessels their structure and flexibility. Combined with L-Lysine, it supports clear, healthy arteries, an idea rooted in the work of two-time Nobel Prize winner Dr. Linus Pauling on cardiovascular health.
Magnesium, Vitamin K2 & Nattokinase — the support crew
Magnesium participates in hundreds of processes, including healthy vessel function and energy. Vitamin K2 helps keep calcium in the bones and out of arterial walls. Nattokinase, a natural enzyme from fermented soy, has a long traditional use for supporting smooth circulation. Together they round out a formula designed to keep vessels flexible, clear and flowing.
