Hi so I have a good healthy and safe dietary supplement that might just work!
It is called CELL FOOD. IT is liquid and you put 8 drops in 8 oz of water. You drink up to 3 glasses a day if you would like. They have lots of products, but this one is very good for energy levels and keeping you in a great mood!
I Just bought some from whole foods a week ago. All ready my energy level is amazing, I feel happy, and I just feel all around good and healthy. I suggest that you try this, it is for all ages and is 100% natural. Here is a link to check it out
