I’m Lam, 70 years old and had a stroke in the past due to high blood pressure. I started taking this supplement (Nutravision) to help manage my blood pressure, and within just three weeks, I saw a noticeable improvement! My blood pressure went from 180/90 to 170/80, and I’ve even noticed that my vision has improved – I can read small print much more clearly now. An added bonus is that it’s also helped with my digestion, making it easier to stay regular.
