Review: Great addition to a heart health regimen! - I was skeptical of these pills when my brother in law recommended them. I have been taking them daily for months just as directed on the bottle. (Empty stomach,lots of water) and my cholesterol levels have been steadily dropping! Of course I’ve made other changes and it’s not just a magic pill but I do believe that these have helped a lot! There’s no after taste and the capsule is very small and easy to swallow.
Review: Great Supplement - I bought this for my husband who has a bit of calcium build-up in a major arterial valve. He is hoping this helps decrease or slow future build-up. He took this for the entire bottle. It did not upset his stomach in any way. I will purchase more for his daily use.
