I like to start my mornings with warm lemon water, this helps to flush out the body of toxins and alkalize our body after a night of detoxification. Not only is it super high in vitamin c, it can also help build up our immune system. A tip I also do during the colder seasons is to add some cayenne pepper to help break down mucus in the body. Also if you are worried about your teeth being sensitive you may also drink your lemon water with a straw to protect your teeth. I recommend half a lemon to two cups of water. Have you tried this?
