Those of us who are deficient and start on a vitamin D supplement usually take five to six weeks to reach the recommended level of vitamin D. If you're in doubt, it's always best to have a chat with your GP who might arrange a blood test. The B vitamins and vitamin C are all water soluble.
In the final stage of the process, the liver and kidneys convert that vitamin D into yet another form of the vitamin -- vitamin D3, the active form of the vitamin that our bodies can use. You need just 10 to 20 minutes of sunlight a day to ensure that your body is producing enough vitamin D. After we reach our seventies, the precursor to vitamin D generally found in skin diminishes three- or four-fold, making it increasingly difficult for us to produce vitamin D naturally.
