No way your question is Off Topic for this forum, and it is a good one at that.
I do not readily know or can readily find a source of organic or natural whole grape seeds if what you wish to do with them is consume them. There are numerous sources for seeds for planting.
Is there a reason you prefer the whole seeds to edible organic grapeseed oil?

Yes, the seeds would be best provided that they are organic and are suitable for eating (seeds for planting may have added ingredients to prevent mold and such).
When you are unable to find seeds, the next option would be to search along the lines of "organic cold processed grapeseed oil".
Oh yes, you are crazy as a loon but we still love you. When we aren't wanting to wring your neck that is.
Gotcha!
