Our Full Review
Atlantic Naturals pairs their signature wildcrafted Irish sea moss with organic beet root in this targeted formula designed for heart health and physical performance.
Beet root is one of nature’s richest sources of dietary nitrates, which your body converts into nitric oxide, a molecule that relaxes blood vessels, improves blood flow, lowers blood pressure, and enhances oxygen delivery to muscles during exercise. Combined with sea moss’s potassium and magnesium, this formula provides comprehensive cardiovascular support.
For athletes and fitness enthusiasts, multiple studies have shown that dietary nitrates from beet root can improve exercise endurance by 1-3 percent, reduce the oxygen cost of exercise, and speed up recovery. Paired with sea moss’s iron and zinc content, you get a natural performance stack.
Each bottle contains 120 vegan capsules delivering 1,000mg per serving. At approximately $25 for a 60-day supply, this is one of the better values in the Atlantic Naturals lineup. USDA Organic certified, third-party tested, and no fillers.
One minor note: beet root can cause beeturia, where urine takes on a reddish tint. This is completely harmless but surprises some first-time users.
