Chia seeds are an important source of omega-3 and omega-6; two essential fatty acids that our bodies cannot produce on their own. Chia seeds contain 5 times more calcium than milk, 2 times more potassium than a banana, 3 times more iron than spinach, and are 3 times richer in antioxidants than blueberries. To top it all off, chia seeds are also a good source of soluble fiber.
