Less than 100 IU (International unit) of vitamin D is considered as the Vitamin D Deficiency. However, this does not indicate that you increase the intake of Vitamin D.

How Much Vitamin D Is Too Much?


If you are among those who still wonder how much vitamin D is too much then this write-up is for you. Institute of medicine on November 30, 2010 recommended the 600 IUs of intake of vitamin D daily.  This is the triple of the amount which was declared by the same Institute in 1997. Therefore, you must be aware of the latest information before deciding your own intake amount.

The following amount of daily intake is recommended by National Institute of Health -

1. For adults who include males, females and pregnant/lactating women the intake is 200 IU. This is for those who are under the age of 50.

2. Elder members of the society who are 50 to 70 years old must take 600 IU of vitamin D daily.

The above mentioned standards are set for the following reasons -

1. Level of vitamin D which is required for the bone strength. This level is must for the smooth functioning of your bones.

2. Low Vitamin D can lead to several autoimmune diseases. It can also cause psoriasis, cancer and diabetes.

In spite of several drawbacks of Vitamin D Overdose, there are several experts such as Dr. Weil, who does not find any harm in increasing vitamin D intake. One of the most trusted gurus of medicine, Dr. Weil advice his followers for 2000 IUs of daily intake of vitamin D.

Factors which affect the amount of vitamin D make by our skin :-

1. The time of the day 

2. Season of the year 

3. The distance of your place from the North. 

4. Percentage of smog in the surrounding. 

5. How much your skin is exposed to the sun? 

6. Skin complexion– fairer skin can make a high amount of vitamin D in fewer time periods. 

7. Sunscreen can protect your skin from harmful rays but also prevents the synthesis of vitamin D in the body.

How much sun exposure to fulfill the vitamin D need of our body?

There is no doubt in this fact that sun is the best source of vitamin D. Dr. Weil’s intake of vitamin D is not only enough for daily basis, but you can also stockpile it for winter season when your best source is not available. You can use a definite formula by M.F. Holick to calculate the length of time for the exposure under the sun.

4 Magical Steps :-

1.Estimate the time when your skin turn pink in the sun.

2. Divide the above estimated time by 25 to 50 percent. 

3. Between 11 a.m. and 3 p.m. are the most beneficial hours of the day. Spend 20 to 30 minutes, which depends upon the above calculated time period.

4. Length of time to the sun exposure also differs with the geographical location and season of the year.

I strongly recommend referring Dr. Holick book, “The Vitamin D Solution” to know your exact time period for sun exposure.

The above mentioned standards for vitamin D are the latest and are subjective to change. Keep updating yourself in every 5-6 months at least. How much VITAMIN D is too much is still a matter of debate but its deficiency can lead to several fatal diseases. Therefore, make a habit of taking necessary components and mineral through your diet. Healthy eating that is fruits and vegetables never cause any problem, whether you know an exact amount of the components or not.
