connection between vitamin D and memory function

According to new research, there may be a connection between vitamin D and memory function. However, this question requires further study.

Vitamin D May Protect You from Alzheimer’s

Researchers have found that people with low levels of vitamin D are likelier to suffer from Alzheimer’s.

It isn’t yet fully clear how this works. But here are some of the effects that vitamin D has on the brain:

  • Vitamin D activates and deactivates enzymes that take part in nerve growth.
  • It also helps create new neurotransmitters.
  • Additionally, it can protect the brain from inflammation.

Thus, getting enough Vitamin D is very important for your brain’s health.

What Is the Ideal Dosage?

Scientists are still trying to find out exactly how much vitamin D a day is optimal for Alzheimer’s treatment or prevention.

According to current guidelines, a daily intake of 400-800 IU (international units) is enough to prevent vitamin D deficiency. This amounts to 0.01-0.02 mg a day. But many believe that this dosage is too low. After all, over 40 percent of Americans suffer from vitamin D deficiency.

The right amount for you depends on your age, sex, ethnicity and the amount of sun exposure that you get. Older people and people with darker skin tones generally need more vitamin D.

What Are Good Sources of Vitamin D?

To maintain healthy vitamin D levels, you should increase your exposure to sunlight as much as possible. There are also some foods that could help, such as canned tuna, beef, mushrooms, and cod liver oil.

Vitamin D supplements are also a good choice for some. However, you should ask a professional before you start taking supplements. Too much vitamin D can have side effects such as nausea, constipation, bone loss, and kidney damage.


There is still a lot of research to do about the connection between vitamin D and memory function. The best dosage is still unclear. However, it is obvious that avoiding vitamin D deficiency is a good way to protect your brain.
