kefirThis Russian drink is made from fermented milk and tastes like yogurt. Its popularity has increased in the west because it is a rich source for probiotics. Like Black Garlic, Kefir is also used to support the immune system and promote healthy digestion. Kefir also contains plenty of other nutrients like vitamin D, calcium, phosphoric acid, magnesium, protein, vitamin B12, and riboflavin. It contains vast amounts of calcium and vitamin K2, making kefir the perfect food for people suffering from osteoporosis or if their bone mass is degenerating. Check the refrigerated aisle at your grocery store for this; it is often placed near the yogurt section.
