Double Wood Supplements Nitric Oxide Booster — Nitrosigine + Citrulline, 180 Vegetarian Capsules, Stim-Free Circulation Support

Double Wood Nitric Oxide Booster is a stim-free circulatory support supplement combining 500 mg Nitrosigine with L-citrulline and two forms of L-arginine to promote healthy blood flow and exercise recovery.

This formula blends a patented, clinically studied arginine silicate complex (Nitrosigine) with L-citrulline and arginine variants to support nitric oxide production and vascular response without stimulants. Packaged as 180 vegetarian capsules, it’s designed for people who want to enhance muscle perfusion, aid workout performance, and support recovery while avoiding caffeine or other stimulants. Manufactured in the USA from globally sourced ingredients, this supplement is non-GMO and gluten-free.

How does this supplement support circulation during workouts?

The combination of Nitrosigine and L-citrulline provides substrates that help the body produce nitric oxide, a molecule that relaxes blood vessels and can improve blood flow to working muscles. Better circulation helps deliver oxygen and nutrients to muscle tissue during exercise, which may support performance and reduce fatigue.

• 500 mg Nitrosigine (arginine silicate inositol) — clinically studied to boost blood flow
• 500 mg L-citrulline — converts into arginine to sustain nitric oxide production
• 250 mg Arginine AKG 2:1 and 250 mg L-Arginine HCl — multiple arginine forms for rapid availability

Can this be taken as a pre-workout on stimulant-free days?

Yes—this product is intentionally stim-free, making it suitable for mornings, late-afternoon training, or any time you want circulatory support without caffeine. Users often take it 30–60 minutes before exercise to take advantage of acute increases in blood flow.

• Stimulant-free formula — no caffeine or central nervous system stimulants
• Convenient capsule form — easy to dose before workouts
• Suitable for stacking with other non-stimulant supplements or protein

Will this help with muscle soreness and recovery?

Clinical data on Nitrosigine indicate it can support reduced muscle soreness after intense exercise by improving circulation and nutrient delivery to damaged muscle fibers. While individual results vary, the trio of nitric oxide precursors in this product aims to assist recovery processes and reduce next-day discomfort.

• Supports nutrient and oxygen delivery for repair
• May reduce perceived soreness after strenuous sessions
• Useful as part of a post-exercise recovery plan alongside protein and rest

What makes Double Wood’s formula reliable and clean?

Double Wood emphasizes ingredient quality and transparent manufacturing: the Nitrosigine dose mirrors amounts used in studies, and the product is produced in the USA under third-party testing practices. It’s suitable for many dietary preferences because it’s vegetarian, non-GMO, and gluten-free.

• Manufactured in the USA from globally sourced ingredients
• Vegetarian capsules, non-GMO, gluten-free
• Contains clinically studied Nitrosigine at an efficacious dose

This Nitric Oxide Booster is aimed at active adults, athletes, and gym-goers who want a stimulant-free way to enhance muscle blood flow, support exercise performance, and help post-workout recovery. It’s a fit for people avoiding caffeine or those who prefer a clinically dosed arginine-silicate complex with complementary citrulline and arginine forms.
