I take a gelcap...it is mixed in an oil. I really don't think the dry powder type supplement is a good idea for D, since it is oil soluble.

I use a supplement enhancer for my morning supps. It is called Bioperine, made by Source Naturals.
Here is a thread about it at PN

I became interested in it because of the Doctor's Best products which have it added. Also there was a study showing this pepper extract can lower cholesterol! So I've been using it.

One has to be careful with DRUGS and Bioperine. Not much information is available on the net about the drugs which may be affected by it. But until further info comes along I think it is similar to the effects of grapefruit juice on drug levels.

I am not really recommending Bioperine for others at this time because of this unknown factor. But I don't take any drugs in the morning, so I am using it to enhance my supplements.
