Nitric Oxide Booster Supplement

Nitric oxide boosters enhance blood flow and circulation, which can improve exercise performance, increase muscle pump, and support cardiovascular health. They may also help lower blood pressure and facilitate better nutrient and oxygen delivery to tissues.

Nitrosigine® is a patented arginine silicate inositol complex developed by Nutrition21. It has been clinically studied at 500 mg—the amount provided in each serving of this formula—for its ability to support nitric oxide production, healthy blood flow, exercise performance, focus, and recovery from exercise-related muscle soreness. Its clinically studied dose and documented research make Nitrosigine® a key ingredient in Double Wood’s multi-pathway nitric oxide formula.

Products providing 6–8 grams of L-citrulline may be better suited to athletes primarily seeking the maximum temporary muscle pump during workouts. Double Wood Nitric Oxide Booster is designed differently: it combines Nitrosigine®, L-citrulline, Arginine AKG, and L-arginine HCl to support multiple nitric oxide pathways. Its convenient three-capsule serving is intended for consistent daily nitric oxide, circulation, and cardiovascular support rather than high-dose, workout-specific supplementation.

Yes. Double Wood Nitric Oxide Booster is designed for daily use and does not depend on exercise to fit into your routine. Nitric oxide plays an important role in vascular function and healthy circulation throughout the body, so this formula may also benefit people seeking everyday blood-flow and cardiovascular support. You can take the three-capsule daily serving whether it is a workout day, rest day, or you do not exercise regularly.

Sports-performance research commonly uses 3–6 grams of standalone L-citrulline before exercise. This formula takes a different approach by combining four nitric oxide pathway ingredients—Nitrosigine® at its clinically studied 500 mg dose, L-citrulline, Arginine AKG, and L-arginine HCl—into a 1,500 mg blend. This multi-ingredient formulation supports multiple pathways involved in nitric oxide production and provides a convenient three-capsule daily serving without requiring workout-specific timing. For those focused on cardiovascular wellness, healthy blood flow, and everyday nitric oxide support rather than maximizing a pre-workout pump, the formulation and dosing are intentional.

Nitric oxide is produced naturally by the endothelium, the inner lining of the blood vessels, and plays an important role in cardiovascular function. It signals the smooth muscle in blood vessel walls to relax, widening the vessels through a process called vasodilation. This helps promote healthy circulation, blood flow, and blood pressure levels already within the normal range. The body’s natural nitric oxide production may decline with age. Nitric oxide precursors such as L-arginine and L-citrulline, along with Nitrosigine®, provide ingredients the body can use to support nitric oxide production. Research suggests that maintaining nitric oxide availability may support vascular function, exercise tolerance, arterial flexibility, and the efficient delivery of oxygen and nutrients throughout the body. Double Wood’s formula combines four nitric oxide pathway ingredients to provide daily support for cardiovascular health, circulation, and overall nitric oxide production (Lundberg JO et al., Nature Reviews Drug Discovery, 2008).
