Can you get sunshine vitamin d through the window?

Here comes the sun..: If the window is open and you're hanging out of it at midday, possibly. Sunshine through windows does not count, because it does not work. You must be outside around midday. Wearing sunscreen also diminishes the effect of the sunlight. Fair skinned, untanned people need less exposure as opposed to tanned, Hispanic or black skin. Over exposure has it's own problems so monitor your time in the sun. ...Read more

If I stick my hand out of my window for 10 minutes a day is that enough vitamin d? I really don't want to go outside it's cold

Vitamin D: Absolutely not. But sunlight in and of itself will not increase vitamin d levels. The sun has to be at a certain angle in the sky. There is a physics involved. In the winter, in the northern hemisphere it is best to get vitamin d as a supplement since the sun is not at a good angle for this vitamin d process. ...Read more

If you are low in vitamin d is it possible to get enough through the sun, milk and other diet or are supplements necessary?

If you are low in vitamin d is it possible to get enough through the sun, milk and other diet or are supplements necessary?

Vitamin D is vital: This is not a simple question. The more we learn about vitamin d the more it appears we should all be on supplements. The sun exposure one needs also includes the need for the sun to be at a certain angle in the sky and this physics part of exposure is partly why sun in general is not the key to good vitamin d. We do not absorb vitamin d very well from food. Many adults should not be on milk. ...Read more

If I put sunblock cream (spf 50 or 100) on my skin and expose my body to the sun, will I get vitamin d normally?

If I put sunblock cream (spf 50 or 100) on my skin and expose my body to the sun, will I get vitamin d normally?

No: When the sun's uv b rays hit out skin, we turn inactive d to active vitamin d. So if you are wearing sunscreen that blocks those rays, then your body will not perform this process and you could be at risk for vitamin d deficiency. You can get a blood test to determine your vitamin d levels. ...Read more

I take vitamin D and calcium every day. I'm 56 and was told when we get older the body doesn't absorb enough D from sunlight. Is this true?

I take vitamin D and calcium every day. I'm 56 and was told when we get older the body doesn't absorb enough D from sunlight. Is this true?

Measurement Required: Cannot correctly begin to control what is unknown/not measured. Healthy vitamin D3 (what counts) concentrations in the 70-80 ng/ml range. Vitamin D is not absorbed from sun. Sun tends to trigger conversion of a little cholesterol in skin cells to Vit D, then converted in liver to D2 & by kidneys & other tissues to D3. D3 impt for Ca absorption from food, bone & muscle strength + immune function. ...Read more

I took 1000 UI of vitamin D and had dirhaea, I tried lower dose 500 UI, but still, why is that? Could that be overdose? I don't get much of sunshine.

Not overdose: It is safe to take 1000-2000 IU of vitamin D3 every day so what you took was not an overdose. Vitamin D can cause loose stools in some people. Try taking the 500 IU daily with your largest meal of the day. If that does not work then see your doctor for a vitamin D level to make sure that you really need to take it. ...Read more

What happens if we don't get enough vitamin D every day?

What happens if we don't get enough vitamin D every day?

Osteoporosis: Bone health depends upon vitamin D. Calcium levels, too. Parathyroid hormone (PTH) depends upon vitamin D to regulate calcium levels. While there is some evidence that vitamin D affects more than bone health, that evidence, while plentiful, isn't of the highest quality eg randomized controlled trials. Everyone agrees that normal 25OH D is more than 30ng/mL. But we disagree as to benefit if higher ...Read more

Vitamin D: Being low on vitamin D is an independent risk factor for major depression. Vitamin D is an important hormone for bone metabolism, so being low increases your risk for osteoporosis.

What can happen if you don't take your vitamin D pills can I just get Sun or do I have to take them?

It depends: If your Vitamin D level is very low (30 or less), taking Vitamin D supplements would be a good idea at least temporarily. You can also be out in the sun, but it will take longer to build up to healthy Vitamin D levels that way -- and presumably this isn't sustainable in your usual lifestyle or your level wouldn't be low in the first place. Your doctor who knows you can give the best advice. ...Read more

Would not worry: While many people believe a healthy vitamin D level has to be >30, I and others believe that >20 is fine. Some people seem to get more of a boost in their D level from sun than others. You could take a vitamin D supplement of 600-1000 units per day to safely boost your D level a bit but I don't think it is necessary ...Read more
