Daily multivitamin use was compared to cocoa extract in more than 2,200 people over 65. After three years, taking a cocoa extract had no benefit while taking a multivitamin led to a significantly slower age-related cognitive decline. This included measures of global cognition, memory, and executive function.
Many physicians discourage their patients from taking a multivitamin. They should stop. There is little downside to taking a multivitamin. It is very inexpensive and safe. Many people also feel that if they eat a well-balanced healthy diet they should not need to take vitamins. Unfortunately, that is not the case. Even foods that are considered healthy are often processed, stored for a long time, or grown in depleted soil. Another problem is that as we age our body loses its ability to absorb vitamins and minerals (as well as protein, which is a different topic).
Taking a multivitamin should be a standard recommendation for those over 65. Many younger individuals need supplements as well. Ironically, a healthy diet (especially vegan or vegetarian) is often deficient in vitamin B12. Many young people whom I see for migraine headaches are deficient in vitamin D and magnesium. The role of vitamin D is also often underappreciated by primary care doctors. Multiple studies have shown that your vitamin D level should be not only within the normal range but in the upper half of the normal range for your brain to function normally. Most people who died of COVID had low vitamin D levels. And I’ve written many times about the importance of magnesium – just search this blog.
Ideally, to approach this problem scientifically, you should have your vitamin and mineral levels checked. This will allow you to take only those vitamins that you are deficient in. the difficulty is that there are too many vitamins to check and the insurance companies often refuse to pay for these tests. Taking at least a multivitamin is a reasonable alternative.
