I am 55 and now I am running 5 miles a day! My hair is so healthy and so are my nails. This is great for stress too with all the B’s in them. I just wish I was taking it when my dad was dying of cancer it would have helped me cope better. It is so easy. You don’t have to take 100 tablets a day that your body cannot absorb anyway. Just one spoonful in the morning and you are done. How easy is that? I don’t have that tired feeling at 3 p.m. like I once did. The cost is reasonable compared to what else is on the market. You can take the juices out there for 3 times more money and it says it will help but look at the ingredients, it is mostly juice. Expensive juice! I love your product! I recommend it to all my friends.
