Dr. Holick explains whether wild or farm-raised salmon contains more vitamin D.
We found that wild salmon get their vitamin D from the food chain, which is plentiful, whereas farm salmon are getting polluted food with very little vitamin D. So it wasn’t a surprise to us when we actually did an analysis of farmed compared to wild-caught salmon and farm salmon have about 10 to 25% of the vitamin D content compared to wild-caught salmon.
