Formulation Factory Heart of Steel – 10-in-1 Nitric Oxide Support | 2-Pack

10 Ingredients. One Comprehensive Cardiovascular Formula.

Heart of Steel by Formulation Factory is a precision-engineered 10-in-1 cardiovascular and nitric oxide support formula. High-dose L-Citrulline and L-Arginine form the vasodilatory core, supporting nitric oxide production, arterial flexibility, and healthy blood flow. CoQ10 (150mg) and Resveratrol (200mg) provide cellular antioxidant protection and cardiovascular resilience. Ginkgo Biloba and Panax Ginseng support oxygen delivery to the brain and muscles for mental clarity and sustained energy. Capsaicin drives peripheral circulation and warmth; Quercetin and Rhodiola Rosea support inflammatory balance and post-activity recovery.

Structural cardiovascular benefits build over 30–60 days of consistent daily use. 2-pack, 240 capsules total — a two-month supply for uninterrupted support.
