I am 73 yrs young, have two stents, and I currently am on Lisinopril for BP and OTC sleep aids as well one prescription for sleep Tamazapan. Over the years I have tried, puchased, and wasted ALOT of money on "empty promising supplements". For the most part, outside a select few, most were very disappointing and could not notice any difference if I took them or not. . . BUT. . . Ancestral Beef Organs have definitely brought about a noticeable difference . I've only started this past month taking various AS products. The first day or two? No difference. After the third day, although I took my usual OTC cocktail I take nightly, I started sleeping all night. . . haven't done that, except on rare occasions in years!. . . . I've sleep all night, every night since. The other improvement I've notice is a "sense" of well being is increasing gradually each day. And the only change I've made is taking various AS products each day. I am currently consuming my stockpile of all my other supplements to eliminate them until I get down to just the supplements I've found to really have an positive effect on my well-being and Ancestral Supplements are going to be my mainstay and go to foundation of my supplementation from here on out.
