Now that you know how beneficial seaweed is to cleansing and nourishing your body, you may be thinking about detoxing with a seaweed cleanse. You might even be wondering how to get your hands on some seaweed! You may be able to find it at the store depending on where you live, but it is most likely dried and has a lot of sodium. It also probably doesn’t have the same nutritional value as of fresh seaweed. To get the best results, you’ll need to use a supplement. Supplements are convenient and easy to use.
