Bests & Worsts Reviews from Amazon

My son's D3 levels were at 33. I was using a brand of drops w/o the K2 added, his levels were exactly at 33 when we tested again 6 months later. At that point I switched to this brand. After 6 months of 4 drops a day (5 days a week) his levels are at 54. He does not get sick as often! These drops have a slight minty taste to them. He is stubborn and will not take them under the tounge like my daughter and myself. I mix it into his peanut butter toast and he has no idea. I would recommend these drops.
