How much vitamin d should I take per day to defeat acne , is there a better solution ?

Do it right: Vitamin d isn't the answer to your acne, and overdoing it is just asking for kidney stones and other serious health problems. Same for vitamin a. I'm sorry you read this junk on the internet. If topical benzoyl peroxide 5% 2x/day has not cleared you in two weeks, get with your personal physician for prescription-strength rx. Acne is a serious illness and deserves 21st-century treatment. ...Read more

Recent blood test vitamin d was 29.8 ng/ml.  Ref range is 30-96.  Have been as low as 20ng in the past.  How much D3 should I take per day?

1000 IU: Your level, as you know, is almost in the normal range. If you increase the amount of vitamin d in your diet, you may achieve normal levels. Or, supplementing with 1000 iu/day should gradually increase your level into the normal range within a few weeks. There is very little risk with remaining on a small supplemental dose of 1000 iu/day. Getting a recheck in 3 months could be helpful. ...Read more

2000 IU okay: Taking 2000 IU of vitamin D3 daily will be sufficient. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Is it safe to take vitamin d (7000 iu) per day?

Is it safe to take vitamin d (7000 iu) per day?

Yes: Hi. Yes, that's completely safe. Vitamin D toxicity is a myth. The active, hormonal form of vitamin D (calcitriol, or 1,25-dihydroxyvitamin D) can be toxic, but not vitamin D. You get an increase of about 6 on your 25-hydroxyvitamin D for every 1,000 Iu/day you take, so depending on your starting 25-D level, you can roughly estimate you'll add 42 to that. You may not need that much, but no harm. ...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

How long does it take for the body to get rid of the excess vitamin "d" that was taken for four and one half years at 50, 000 units per day?

How long does it take for the body to get rid of the excess vitamin "d" that was taken for four and one half years at 50, 000 units per day?

Why: Were you taking it? The solution is to get the blood level checked. It should be somewhere between 60 and 80. It may well be that you have achieved an ideal level. Vitamin d is really a hormone that is made by the action of sunlight on the skin. Oral intake was never intended by god and it is very poorly absorbed. Get it checked out. ...Read more

How long does it take to cure vitamin d deficiency on 2000u per day?

How long does it take to cure vitamin d deficiency on 2000u per day?

Hard question: Because a person may be getting varying amounts of vitamin d from the sun , how long it takes to build up or deplete will vary. That being said, vitamin d from food or supplements have a half-life of 20-30 days, therefore a month should be plenty of time to build up in the system. Thank you. ...Read more

My vitamin d was so low cleveland clinic has be take 50000 units a week for 8 weeks. That brought it up to the bottom of the range. I now take 10000 per day to maintain my level. Why do I need so much. I get regular sun exposure?

Probably don't need: There i s much debate regarding how much vitamin d a person needs. Some say below 10 is deficiency, others below 30, while even others say below 40. It is fat soluble vitamin which means it may be stored in fat and not always detectable in the blood. Try wild salmon and fortified foods and don't exceed 1, 000 iu per day. If you don't have any symptoms that should be okay. Try another lab as well. ...Read more
