Flax seeds, also known as linseed, share many properties with chia and are highly valued for their nutritional benefits. They are an excellent source of polyunsaturated fatty acids, especially Omega-3 and Omega-6, which are essential for maintaining a healthy nervous system. Additionally, they provide a wide variety of minerals such as iodine, iron, zinc, magnesium, calcium, potassium, manganese, silicon, copper, nickel, phosphorus, and chromium, among others. These seeds are also notable for their content of vitamin E and several B vitamins, including B1, B2, B3, and particularly B6, which are essential for multiple bodily functions. Like other plant-based foods, they are naturally gluten-free, making them suitable for people with gluten intolerance or sensitivity.
