Guest guest Posted August 24, 2009 Report Share Posted August 24, 2009 Hi there, The Muran warriors of the Masai culture would bleed a gallon of blood out of their cows every so often. It did not kill the cows. What if you were to bleed all of your cows here and there and ferment/centrifuge the vitamin D in it and sell it as a supplement? This would be for people that have plenty of vitamin a from grass fed liver on a regular basis. Blood is a rich source of vitamin D. I think the WAPF website states that cow blood contains 4000 IU of vitamin D in 3.5 oz. of it. Thank you, Holt Quote Link to comment Share on other sites More sharing options...
