Product approved by my doctor.
Supplement indicated by the doctor nutrologist that I consulted. I felt better and more energetic after 1 month of use. I have felt less tired and more energetic, not lacking in training in the gym (what used to be a rule I used to be absent). My concentration and ability to reason also improved significantly. Which were the main reasons that the doctor recommended me this vitamin. Added to the fact that I feed badly, this problem is already practically solved. I heard that this supplement also improved the appearance of the skin, reducing the wrinkles and making it more shiny and silky, but I confess that I did not notice this part. For these purposes I read that the ideal would be to combine this vitamin with the use of hydrolyzed collagen. I want to arrange, because I'm curious to see if it works. Packaging well finished and with descriptive label very detailed. It arrived quickly and I am already arranging the purchase of another order because the doctor liked my exams after two months of use of the vitamin. I have not tested other brands, but as I am satisfied with the results I have obtained so far, I will continue with NOW.
