Re: How much vitamin D do I need?

According to one doctor who practices in 'sunny' Southern California USA he said that the majority of his patients are vitamin D deficient.  So I think that unless we all become nudists that supplements are the way to go.

Below is the recommended amounts by the Vitamin D council, a group of medical doctors.

I am not familiar with the brand that is listed in your link.

........For proper functioning, a healthy human body utilizes around 3,000-5,000 IU of vitamin D per day - indicating the current recommended intakes are not high enough to raise and/or maintain the vitamin D levels necessary for proper health.

Vitamin D Council recommended amounts

Based on the body's indicated daily vitamin D usage, Vitamin D Council recommends the following amounts of supplemental vitamin D3 per day in the absence of proper sun exposure. Due to the variable response discussed above, these are only estimated amounts.

• Healthy children under the age of 1 years – 1,000 IU.
• Healthy children over the age of 1 years – 1,000 IU per every 25 lbs of body weight.
• Healthy adults and adolescents – at least 5,000 IU.
• Pregnant and lactating mothers - at least 6,000 IU.

Additionally, children and adults with chronic health conditions such as autism, MS, cancer, heart disease, or obesity may need as much as double these amounts.

Tolerable Upper Intake Level

The US Government’s Tolerable Upper Intake Level (UL) for vitamin D is set at 4,000 IU per day. While this is a step in the right direction from the previous UL at 2,000 IU per day, in some situations - such as with those who are obese - it may still be too low. An upper limit this low will also result in the prevention of adequate doses from being used in studies, greatly curtailing our understanding of vitamin D’s physiological effects as well as the true extent of its treatment potential.

Current expert consensus is that the US Government UL for vitamin D is too low and that it should be raised to 10,000 IU per day. Since this is the amount one would naturally produce in their skin from sun exposure, it is considered safe.
