DHC was founded in Japan in 1972 on a simple principle: create supplements that work as promised, with no shortcuts. We created this Citrulline formula because modern life—long hours, processed foods, and constant stress—makes it harder for your body to perform at its natural best. Our research team in Tokyo selected only the highest-purity L-Citrulline, sourced from a single, trusted Japanese facility. Every batch is tested in our GMP-certified labs for purity and potency, a standard set by Japan's Ministry of Health, Labour and Welfare. This commitment to quality is why this formula has become a top-ranked choice for performance and circulation support in Japan, trusted by customers for over a decade.

The DHC Citrulline Supplement is formulated with high-purity L-citrulline as its primary active ingredient, derived from fermentation processes to ensure quality and potency. L-citrulline is a non-essential amino acid that plays a crucial role in the urea cycle, where it is converted into L-arginine in the kidneys, subsequently boosting nitric oxide production in the body. This mechanism supports enhanced blood flow and vasodilation, which can improve exercise performance by reducing fatigue, increasing endurance, and aiding in post-workout recovery through better oxygen and nutrient delivery to muscles. Additionally, the supplement may contribute to cardiovascular health by promoting healthy blood pressure levels and reducing muscle soreness. The product typically includes minimal excipients such as microcrystalline cellulose or magnesium stearate for stability and capsule formation, ensuring a pure and effective formulation focused on delivering the benefits of L-citrulline without unnecessary additives.
