How do I know how much vitamin d supplement should I take?

How do I know how much vitamin d supplement should I take?

It depends: This depends on sun exposure. In spring & summer if you get some mid-day sun without sunscreen you don't need to take any. Everyone should take d in fall & winter as the sun is not high enough for the rays that produce d to reach us. Most adults need 5-8, 000 iu/day for optimal levels.

Would taking 1800 mcg of vitamin d +400 mcg of calcium in be too much to take? Vitamin d low with 1400 mcg supplemented daily. I am 47yr old female.

Would taking 1800 mcg of vitamin d +400 mcg of calcium in be too much to take? Vitamin d low with 1400 mcg supplemented daily.  I am 47yr old female.

Ask your doctor: If you have low vitamin D three levels, you should probably start supplementing. However because it is a fat-soluble vitamin, it can accumulate and build up reserves rather quickly, so you want to follow your doctor's advice on how quickly or fast s/he wants to do this. Also your ratio of calcium is off. So best to discuss this with your doctor to get you back on track. ...Read more

What are the best vitamin d supplements? How much should one take?

What are the best vitamin d supplements? How much should one take?

Any brand will do: Counter to what a salesperson might tell you, there's not much money to be made selling vitamin D. As long as the label has a USP DSVP symbol on it, you're pretty assured of its quality. So don't buy fancy brands/names - just make sure it's D3, not D2. For most, 1,000-2,000units each day should be fine. Take enough to bring your 25OH vitamin D above 30ng/mL. Don't check 1,25 diOH vitamin D. ...Read more

My vitamin d level is 29, should I take a supplement and how much per day?

My vitamin d level is 29, should I take a supplement and how much per day?

Probably not needed: The institute of medicine recently did a review of vitamin d needs. They concluded that we probably take more than we need. It is hard to tell from your number just what form of vit d was measured, and what the units are. If you are referring to vit d oh, measured in ng/ml, a level of 20 ng/ml is thought to be adequate. ...Read more

Should I take vitamin d supplement?

Should I take vitamin d supplement?

Maybe: Recently we have realized how important vitamin d is and how many people are deficient. We require sunlight to "activate" the vitamin d we get in foods, some people don't get enough in food anyway. Check with your doctor, they can measure your vitamin d level. Most people can take 1000 iu daily with no risk of any potential toxicity so i recommend adding that amount daily to most of my patients. ...Read more

Can one take vitamin d supplement more than 20000 units per day?

Vitamin D: Supplementation is generally approx 2000 units of d3/day. 20, 000 units would be excessive for most people, and is rarely given concurrently with calcitriol, which is activated vitamin d. . D deficiency takes months to correct. Check w/your doctor about your medication before you continue or change anything. ...Read more

Is vitamin D result 23 Too LOW SHOULD I TAKE SUPPLEMENTS OR THE LEVEL IS FINE?

Is vitamin D result 23 Too LOW SHOULD I TAKE SUPPLEMENTS OR THE LEVEL IS FINE?

Too Low at least 30+: At one time the normal level was considered to be 20 ng/dL. As more has been learned about vitamin D and it's effects on the whole body that was raised to 30 or 32 depending on the lab. However, the normal range goes from 30 to 100 and from that you can see even 30 may be low, but you can get too much too. Other lab values that can help when looking at approp of vitamin D and supp as well. ...Read more

My vitamin d was 24 last time checked. Should i still take a D3 supplement and if so, is there a certain brand that's best?

My vitamin d was 24 last time checked. Should i still take a D3 supplement and if so, is there a certain brand that's best?

Yes, however...: Normal levels of Vit D are 30-100, though 50-80 is the optimal level. Achieving good levels helps prevent heart disease, cancer, autoimmune disease, infections etc. In fall & winter all adults should take 5-8000 iu/day. In spring and summer spending about 20 min. in mid-day sun without sunscreen can give enough D but if you don't do that take year-round. Best with K. Many good brands- see comment: ...Read more

Vitamin D was low 17nmol/l.I took vit D supplement 10,000 IU for 2month it become 156 nmol/l .should I take supplement always ?!or stop¡

Vitamin D was low 17nmol/l.I took vit D supplement 10,000 IU for 2month it become 156 nmol/l .should I take supplement always ?!or stop¡

Depends on sun exp.: 156 nmol/l = 62 ng/ml which is just where you want it (optimal levels are 50-80). But if you stop the levels will likely decline, so it seems wise to continue 10,000 iu/day. The only other way to get significant amounts of D is via exposure to mid-day sun without use of sun screen. If you don't get sun, then it is wise to continue supplementation.

I have low Vitamin D a level of 13.I was started out on a 50000 D2 supplement and became sick after 1 pill.What could I take now to br ok no it up?

Ask your doc if: you can take 5K IUs of D3, once daily. You can find it in the health food store. Your D3 is very low and this can raise it. Look for an optimal lab reading of between 50 & 80. That's what the D experts suggest. Peace and good health. ...Read more

I'm curious what occurs if i don't take my vitamin d supplements?

Well......: Unless you are one of the very few patients that actually need Vitamin D due to documented deficiency or possibly suggested due to an illness or medication interaction, nothing will happen if you do not take your supplement. Indeed, most likely nothing happens to you if you DO take the supplement. That is why these products are not strictly regulated by the FDA. ...Read more
