By releasing the nutrient-rich oil of Atlantic Cod livers through carefully controlled lacto-fermentation, the nutrients in the oil are not only preserved, but enriched. The resulting oil is abundant in a variety of important nutrients, such as omega-3 fatty acids, vitamin D, vitamin A, vitamin K, and many more. We have then further fortified our fermented cod liver oil with vitamin K2 from Natto - the most nutrient rich source of vitamin K2 (MK-7). The vitamin K2 found in natto naturally enhances the benefits of fermented cod liver oil. Vitamin K2 works directly with vitamin D3 to maintain healthy bones, and omega-3 fatty acids to maintain a healthy cardiovascular system. The synergistic relationship between these nutrients is well understood and researched. We have then flavored our blend with wild mint oil, which tastes amazing!
