This is the perfect little kit for me due to my budget and not needing the products very much but do want on hand for those unforseen moments. My favorite product is the REST, I tried it on a Friday evening to be sure it wouldn't make me feel drowsy in the morning and did it come thru! I was restful and sleepy about 30 to 40 minutes after taking it and sleep so sound 😴 with no after effects in the a.m. The adapt serum is my 2nd and I use on my face and notice a difference in appearance for the better. Have not really needed the RELIEF just yet again since my 1st purchase but glad it's on hand for when that day comes. Have only used 1 of the histo complex and can't quite give an actual review just yet. But if you're wanting to go to a more natural way of healing, this is a great start and I highly recommend.
