Dr. Weston A. Price identified numerous benefits of concentrated butter oil, which he referred to as â€œhigh vitamin butter oilâ€ and described in his 1939 book, Nutrition and Physical Degeneration. Even more significantly, Dr. Price came to realize that the special concentrated butter oil worked best in synergy with cod liver oil. â€œOne without the other did not do his patients justice, but the two together worked like magic.â€
Green Pasture Products established the Blue Ice Royal product line to recreate this magical synergy and honor Dr. Priceâ€™s discovery. The Blue Ice Royal line combines our concentrated butter oil with our fermented cod liver oil in one convenient and easy-to-take product.
