How much is the ratio of curcumin and piperine?

There is a preparation of curcumin and piperine from a reputable manufacturer. It can be found at this link: http://www.amazon.com/Doctors-...000BD0RQS/ref=sr_1_2

The ratio is 500 mg curcuminoids and 3 mg piperine in each capsule. The dose recommended by the manufacturer is 1 to 3 capsules per day.

Keep in mind, there is no proof of any kind that this preparation helps Kennedy's Disease.

Many thanks
