This I bought for my husband. Swanson's price is hands-down the least expensive rye pollen extract anywhere, about 50% of the cost and the exact same wonderful extract. Still, it's a little pricey, but I see that it is very worth it. It has helped my husband a lot. I give him 2 capsules of this every day, plus a high potency blend of sitosterols, also available at Swansons. If you do some research, you will see that this particular type of pollen extract has many many different health benefits. Very good product.
