If she has access to clean raw milk, she should drink 1 quart per day. Also, if fermented veggies sound good those would be great for her as well as foods cooked in grass-fed butter, liver from a grass-fed cow, and the cod-liver oil that Sarah suggested. There is a great brand on the WAPF website--it's cod liver butter, which contains the essential fats so that she can properly absorb the fat-soluble vitamins. The orange and he cinnamon flavors are my favorites so far. Best of luck to her!!
