If you are sitting in the sunshine behind glass will you still get the benefits of vitamin D?

Not as much as sitting outdoors. The glass shields some of the UV rays.

I would agree with the others in that if you haven't been otherwise instructed by a physician, do not supplement kids.\n\nas a rule, you yourself shouldn't require daily supplementation.  this is because if you get enough sunlight (15-30 minutes a day depending on where you live relative to the equator and what season it is), typically your body will make it's own Vitamin D by converting cholesterol into the required form.  You do not need to supplement cholesterol either because everyone makes more than enough from your liver (this is why using diet to control cholesterol is only moderately helpful).\n\nThere may be worries such as "I'm fair skinned and can't get sun" or "I live in Nome, Alaska", but really 15 minutes a day is nothing, and much safer than risking oversupplementing with children.\n\nAs with all fat soluble vitamins (A, D, E and K), the policy is to err on the side of caution.  Since these are not water soluble (in which case excess supplements are disposed of in the urine), excess D will accumulate over time in the fat stores and can cause a number of problems later on (especially since various forms of Vitamin D or activators of gene expression).

NO. JUST DO IT UNTIL YOU NEED GLASSES.\nYOU WILL BE FINE.

It is a fact that when ultraviolet light touches your skin it causes your body to naturally produce vitamin D. Vitamin D has been linked to treat and/or prevent many diseases and conditions. For example, Dr. Holick Professor of Medicine, Dermatology, Physiology, and Biophysics at the Boston University Medical Center has found substantial evidence that the Vitamin D you get from tanning can help with the following diseases and conditions:\n\n    * Breast Cancer\n    * Colon Cancer\n    * Depression (Nonseasonal)\n    * Fybromyalgia\n    * High Blood Pressure\n    * Multiple Sclerosis\n    * Osteomalacia\n    * Osteoporosis\n    * Premenstrual Syndrome (PMS)\n    * Prostate Cancer\n    * Psoriasis\n    * Rheumatoid Arthritis\n    * Seasonal Affective Disorder (SAD)\n    * Type 1 Diabetes\n    * Type 2 Diabetes

yes\nthe water actually magnifies the suns rays so you get burnt worse more times then not.\nit is important to wear a high factor sun screen that is waterproof and reapply every 2 hours.

Vitamin D allows Calcium to be absorbed in your system.  Without it, the calcium just passes through.  I would suggest getting some calcium supplements (usually less than $20 for a month supply) which usually contain Vitamin D also.  Exposure to the sun also gives you Vitamin D so be sure to get plenty of sunshine!

Both the systems are different.Ther is no direct connection between both these two systems\nBut one important thing that is VIT  D .It is most important for bone growth and density of calcium in the bones.VIT D can be actively produced by the body in the presence of ultraviolet rays from sun. and vit D it goes in to blood stream and promote the bone growth.Nothing more than that

Vitamin D is required for the formation of strong bones and teeth. It is manufactured in the skin by the activation of a sterol (7-dehydrocholesterol) by ultraviolet radiation (sunlight).Vitamin D is classified as a vitamin because it is required for metabolism and deficiency can result in disease, including rickets and osteoporosis.\n\nVitamin D is passively produced in skin exposed to ultraviolet B radiation. The cholesterol precursor, 7-dehydrocholesterol, is unstable to UVB light, and the B-ring of the steroid structure breaks open to produce the seco-steroid, vitamin D3, more formally known as cholecalciferol. Diet is usually a minor secondary source of vitamin D, but foods such as oily fish and eggs contain only very small amounts. It is almost impossible to obtain sufficient amounts of vitamin D from diet alone, without sunlight exposure. \nHope this helps it might be in a little too much depth but it is the book answer.\nTimster

Drink lots of water and get lots of sunshine.  Sounds dumb I know but the water increases the metabolism and flushes toxins out of the body and sunshine increase the serotonin levels.  Both will help boost your energy.

There is a relationship between sunlight and Vitamin D - a vitamin that controls many things inside your body including calcium.  What begins with light hitting your skin continues with another special reaction that occurs in your kidney.  Does this help your concern?

No...you will not die,,,chances are probably better that you would die from drinking vit D milk....Breast milk has more vitamins....thousands of babies drink it!!!! It must be safe

It would depend on how much the sun really bothers your eyes, and I guess does it matter to you how you look.  You can always buy the clips that go on your prescription glasses, which would be way cheaper.

I haven't heard much about how far away you should sit, except that it should be comfortable for you.  I wanted to comment on another answer that stated that you should turn down the brightness to decrease the amount of radiation.  There's been a lot of hype about UV radiation from computer screens lately and actually, monitors emit UV at a level 10,000 to 100,000 times LOWER than the levels known to cause any eye or skin damage.  Also, make sure that you take breaks about every 20 minutes when you're working on the computer to relax your eyes.

600 mg. It wouldn't hurt to take some vitamin D with that.

No!  If you look at the sun for too long you will go blind!

If you looked into it for a long period of time, you might have some damage; however, if it flashes into your eye briefly, it's nothing to worry about.  By comparison, looking at the sun would be a LOT worse for your eyes.
