Frequently Asked Questions
How much Vitamin D do seniors need?
The general recommendation for adults over 70 is 800 IU (International Units) per day. However, this is just a baseline. Your individual needs may be higher, especially if you have a deficiency or certain health conditions. Only your doctor can determine the right amount for you based on a blood test.
Can I get enough Vitamin D from my diet alone?
For most people, it is very difficult to get enough Vitamin D from food alone. While eating fortified foods and fatty fish is beneficial, it’s often not enough to correct a deficiency or maintain optimal levels, which is why a combination of sensible sun exposure and, if needed, supplementation is often recommended for seniors.
Is it possible to take too much Vitamin D?
Yes, it is. Since Vitamin D is fat-soluble, your body stores the excess. Very high levels can lead to a condition called hypercalcemia (too much calcium in the blood), which can cause nausea, weakness, and kidney problems. This is why it is so important to never take high-dose supplements without medical supervision.
Does where I live affect my Vitamin D levels?
Absolutely. If you live in a northern climate (for example, north of Atlanta in the U.S.), the sun’s rays are not strong enough for your skin to produce Vitamin D during the winter months (roughly from November to March). People in these regions are at a much higher risk of deficiency and should be especially mindful of discussing their levels with a doctor.
