Can caffeine cause vitamin d deficiency?

Caffeine has been shown to negatively affect the efficiency in which the body metabolizes Vitamin D. While the caffeine does not actually deplete the body's store of vitamin D the presence of caffeine will slightly deplete the amount of vitamin D the body is able to metabolize. Since vitamin D is a component necessary to metabolize calcium, regular overdose on caffeine can be very detrimental to your bones' health this is especially true for women over the age of 50 who are at a higher risk to develop osteoporosis. In addition a vitamin D deficit can be a contributing factor to depression. Caffeine should be avoided. Most people drink coffee when they wake up and mid-afternoon. The reason most people are so tired in the morning is that they are simply dehydrated. If you find yourself being lethargic in the afternoon you are probably dehydrated and relying solely on carbohydrates for energy. Exercise, a balanced diet, enough sleep and drinking 64 ounces of water a day will ensure a healthy, alert, vibrant body.
