Although it is well-publicized and considered to be an essential need, I find when I mention it to most of my family and friends, few of them take it! I spread the word of its interaction with and amplification of other nutrients hoping to help them improve their health. Your product is very well absorbed and fast working - our annual medical blood workups prove this to be true. I use it to work together with Vits. K-2, D-3, C, Zinc and E to supercharge my immune system during this stressful time. Thank you!
