By the way, I certainly hope that you are aware that there is a maximum safe dosage of vitamin D:

Children age 9 years and older, adults, and pregnant and breast-feeding women who take more than 4,000 IU a day of vitamin D might experience

Nausea Vomiting Poor appetite Constipation Weakness Weight loss Confusion Disorientation Heart rhythm problems Kidney damage

https://www.mayoclinic.org/drugs-supplements-vitamin-d/art-2...

Recommending 3900 IU for a 195 lb man is alarmingly close to the level that can cause kidney damage and heart issues. If your model spits out 1,000,000 for a 50,000 lb woman, it probably will go over 4,000 given the right parameters.

Hi treis, we're working with one of the world's experts on Vitamin D and using clinical research based on studies conducted on populations over four decades. See one of his publications specifically looking at breast-feeding women and safe <4000 IU figures. http://pediatrics.aappublications.org/content/early/2015/09/...

Regarding the 1,000,000 Vitamin D response: typically our human customers are not 50,000lbs (a blue whale is typically 40,000lbs). However, it's probably not that unforeseeable if a blue whale has higher requirements for Vitamin D than an average human that's 195lbs. To your point though, we are careful that we do not go grossly over Recommended Daily Allowances, and our formulations reflect clinical research.
