@haidut hope this is not redundant - are you aware of the study cited here? Very confusing figuring out what to take (ingest) when. Thanks!
A 2015 study (12) looked at absorption in mice to see whether consuming more than one fat soluble vitamin at a time increased or decrease the absorption of the others. The study showed “significant competitive interactions for uptake” between Vitamin D, E, A and K. It seems that the only fat soluble vitamin that did not lose out was Vitamin A when taken with vitamin E.
The recommendation on Consumer Lab is that if you want to benefit from maximum absorption on your Vitamin K that you take it at least 3 hours apart from other fat soluble Vitamins (D, E and A). To learn more about this listen to my interview with ConsumerLab’s CEO, Dr. Tod Cooperman on Calcium Supplements for Osteoporosis.
