In my opinion there is truly no real effective drug or even natural product as effective against chronic disease as getting appropriate sunlight, cutting out all sugars, getting off of seed oils and stopping the consumption of refined carbs. What really helps is walking each day over 45 minutes, start a resistance training program and drinking good, clean water.

Also, getting outside in the sunlight will actually help your body release melatonin and that will help you sleep better at night.
