What supplements are good for brain health? Supplements that may benefit senior cognition include omega-3 fatty acids and B vitamins. Consult a doctor in Waxahachie, TX, before adding brain-focused vitamins to your routine.

According to the Alzheimer's Association, about seven million Americans live with Alzheimer's disease. This number could rise to 13 million by 2050. Without memory support, your ability to function (and with it, your independence) may deteriorate.

For example, you may struggle to focus, make decisions, or complete daily tasks. About one in three older Americans dies with Alzheimer's or another dementia (making it the sixth-leading cause of death among seniors aged 65 and older).

Before that happens, consider adding brain-focused vitamins to your daily routine. What supplements are good for brain health, and how can you improve your senior cognition? Read on to find out.

What Supplements Are Good for Brain Health?

No one supplement will improve your memory or cognition. However, taking supplements may improve your thinking skills and memory if you have low levels of:

  • B12
  • Zinc
  • Vitamin D

These brain-focused vitamins may improve your concentration and ability to think clearly. Consult a doctor before adding these brain-focused vitamins to your routine. They'll ensure you don't take supplements that may interact with medications you're taking.

Here are a few supplements that may improve your brain health as you age.

1. B Vitamins

Vitamin B12 may help improve your memory, focus, and energy levels if you have a deficiency. Low levels are linked with brain disorders (like Alzheimer's, Parkinson's, and dementia) and cognitive problems. Taking a vitamin B12 supplement may help reverse some dementia symptoms.

You can add B12 to your diet by eating meat and dairy. Consider taking a supplement if you follow a plant-based diet.

2. Vitamin C

According to Travica et al. in Frontiers in Aging Neuroscience, people with adequate blood levels of vitamin C performed better on tests that assessed:

  • Memory
  • Reaction time
  • Attention
  • Focus

Low vitamin C levels are linked with depression and cognitive impairment. Taking a supplement may help improve your mood and cognitive performance.

3. Vitamin D

Vitamin D deficiencies are linked with heart disease, depression, and dementia. This vitamin keeps the immune system, heart, and bones healthy.

Low vitamin D levels may increase your risk of dementia and cognitive impairment. However, taking a vitamin D supplement may not help patients with Alzheimer's disease. Consider taking a vitamin D supplement if bloodwork determines that your levels are low.

4. Omega-3 Fatty Acids

Omega-3 fatty acids are a type of polyunsaturated fat. They may offer anti-inflammatory benefits. Otherwise, free radicals can cause oxidative stress, potentially increasing your risk of cognitive decline.

Omega-3 fatty acids play an important role in the brain's development and function. Deficiencies are linked with attention-deficient hyperactivity disorder (ADHD) and dementia.

Taking an omega-3 fatty acid supplement may help improve:

  • Attention
  • Memory
  • Behavior
  • Learning
  • Blood flow to the brain

Taking a daily omega-3 supplement may help protect your brain from age-related cognitive decline. Avoid taking omega-3 fatty acids if you're on blood-thinning medication.

5. L-Theanine

L-Theanine is found in green tea. It could help improve your reaction times, memory, and alertness. It also supports relaxation and reduces stress.

L-Theanine offers antioxidant and anti-inflammatory benefits. It may help improve executive functioning and verbal fluency.

6. Magnesium

Magnesium plays a role in:

  • Energy production
  • Blood pressure regulation
  • Enzymatic reactions
  • Nerve function

A deficiency may cause brain fog and difficulty concentrating.It may increase your susceptibility to stress, which can cause memory issues.

What Is the Fastest Way to Improve Brain Function?

Effective strategies that may help improve your daily brain health include:

  • Exercising
  • Socializing
  • Getting seven to nine hours of sleep each night
  • Eating healthy, nutritious meals
  • Challenging the brain

Explore your senior living community's events and activities calendar. You can discover fun hobbies that can stimulate the mind and improve your mood. Challenging your brain may improve its function and working memory.

Engaging in activities may help reduce your risk of social isolation and loneliness, which are associated with dementia.Ask friends to join you for exercise classes. Working up a sweat may help reduce your risk of Alzheimer's disease.

To add brain-healthy nutrients to your diet, explore your senior living community's dining program. They can help you develop a customized meal plan with brain health in mind.

Consider moving into a senior living community that offers memory support. Their personalized services may improve your health and quality of life.
