Important to raise: Vitamin C isn't stored so levels vary from day to day so a low C level may not be significant. Take 500-1000 mg 2x/day.However, low D is associated with increased risk of cancer, heart disease, autoimmune disease & a shorter lifespan, so I consider it quite serious, but it's easy to correct. Most adults need 5-8000 iu of D3/day for optimal levels.See http://huff.to/1fzsrQ3 & http://bit.ly/1gNXNk0
