Yay Weston Price! I thought I had a hormonal issue as well, but nothing ever showed up on any tests... I really think it's a nutritional deficiency in the modern diet that manifests more in some of us than others. I take 1 tsp per day of the CLO/butter oil gel. The calculations are really confusing but this is what I have:

Standard dose:  10,000 IU/day of vitamin A
= about 1 tsp high-vitamin CLO
= 2 tsp regular CLO
= 6-10 capsules

Weight loss / health recovery: 20,000 IU/day of vitamin A
= about 2 tsp high-vitamin CLO
= 4 tsp regular CLO
= 12-20 capsules

I can't remember the exact time frame but I think it was about a month when I realized I wasn't breaking out at all before my period.
 Let me know how you get on!
