🧪 Formulation Notes

Prosta-Strong Red is designed for men who are looking for a natural way to support prostate health as well as blood flow.

Prostate Support: This formula features Saw Palmetto extract, which supports the male genitourinary system, prostate health and promotes healthy urinary flow in men as they age. Beta Sitosterol and Pumpkin seed oil supply natural fatty acids and plant sterols that deliver beneficial nutritional support to the prostate gland. Blood flow support: Nitric oxide is a naturally occurring compound in the body that plays a key role in cardiovascular and sexual health. When nitric oxide is present in healthy males in sufficient amounts, erections occur during the normal course of intimacy. This unique formula features L-citrulline, an amino acid that is readily converted to L-Arginine within the body, which can then be converted to Nitric Oxide.

What makes us different: Liquid soft-gels - The nutrients in these easy-to-swallow liquid soft-gels are released fast. Other forms of delivery can contain binders and fillers that may cause stomach upset and offer no nutritional value. Advanced liquid soft-gels provide an optimum delivery system.

Quality Assurance - Irwin Naturals is committed to providing the highest quality products for your health. We employ compliance testing to ensure purity and potency. Patented BioPerine - Our special BioPerine Complex enhances the bioavailability, absorption and potency of many nutrients.
