I liked Detrimax. I really feel like it "works". My lack of vitamin D manifests itself in the form of poor sleep, aggression. As she began to take Detrimax 1 tablet in the morning, she began to sleep well. More strength and energy appeared. I recommend!
I am for any vitamins in the natural - vegetables, fruits, fish oil. And now a bunch of complexes are sold in pharmacies - choose the taste, color and wallet)
