Calroy manufactures and distributes Arterosil®, a natural supplement for vascular health. A recent study showed that the product increased arterial elasticity by an average of 89.6%. Earlier research established that Arterosil helps rebuild the endothelial glycocalyx, the slippery gel lining of every artery, vein and blood vessel. Reported benefits include reduction of neuropathic pain and improved sexual performance. Over $20 million and 15 years of study have been invested in Arterosil.
