I have purchase this product several times from iherb for a few reasons.
1) The product is always in stock.
2) The price is always lower than any of the other sites that I have searched.
3) Delivery of product has always been within the promised date.
4) Website is very customer friendly.
5) Product is always fresh.
My husband has used this product along with the high blood pressure tea every day for several years and noticed a decrease in his blood pressure. he no longer takes the blood pressure medicine. He takes one tablet in the morning at one at bedtime. He will continue to purchase this product. The price is very affordable from I Herb. Most other sites are much more expense. If you have high blood pressure it's worth a try. Better than taking the prescriptions. It took about a month to really notice a big difference. He's been taking it now over 2 years.
I am diabetic and consequently have a problem with blood pressure. Since I am also a carrier for the herpes virus, which is activated by the supplement Arginine It is imperative that use a product that does not contain Arginine. Pressur-Lo is safe for me AND it helps keep my blood pressure down!
