Interesting Fact
Fermented Foods: Traditional Process Adds Extra Nutrients
Fermented foods, like sauerkraut, kimchi, and yogurt, are made using beneficial bacteria or yeast that break down natural sugars. This age-old process often increases levels of vitamins, enzymes, and beneficial compounds in the food. That’s why supplement blends may include fermented foods: to deliver nutrients and unique bioactive substances made during fermentation that aren’t typically found in the raw ingredients.
