Key takeaways:
As you age, or develop certain health conditions, your body may not absorb vitamins and minerals from food the way it once did.
Taking in an adequate amount of vitamins and minerals can lower the risk or slow the progression of many diseases.
The best way to get important nutrients is through food. But supplements may help ensure you’re getting enough vitamins and minerals.
We all need vitamins and minerals for our bodies to function well. There are some you need more as a kid, and others you need more as you get older. And with age, there’s a greater risk of having health conditions that can be helped or prevented with nutrition. But as your body changes, you don’t always absorb vitamins and minerals the way you did before.
Here are some vitamins and minerals you need — but might not be getting enough of — if you’re over 50.
1. Vitamin A
Vitamin A is good for your eyes. It helps to lower the risk of macular degeneration in some people, which is a major cause of vision loss with age. Eating foods with vitamin A may also lower the risk of some types of cancer.
Food sources
Some food sources of vitamin A include:
Herring
Salmon
Beef liver
Spinach
Sweet potatoes
Carrots
Squash
Cantaloupe
Mango
Apricot
Eggs
Milk
Cheese
How much do you need each day?
Men over 50 years: 900 mcg
Women over 50 years: 700 mcg
What else you should know
You might need more vitamin A if you have ulcerative colitis, Crohn’s disease, or celiac disease. People with cystic fibrosis are also at risk of vitamin A deficiency.
Can you take too much?
Extra vitamin A is stored in the liver. That means taking very high doses isn’t a good idea. The maximum daily dose of vitamin A is 3,000 mcg. High doses can cause anything from headaches to liver damage.
2. Vitamin B1 (thiamine)
Vitamin B1 (thiamine) is important for a healthy nervous system and cardiovascular health.
Food sources
Some foods that contain vitamin B1 include:
Whole grains

Many over-the-counter (OTC) antacids contain calcium. If you take them, that counts toward your daily total intake.
Women after menopause have the highest risk of fragile bones. Their calcium intake is especially important.
Calcium can affect how your body absorbs some medications, so it’s a good idea to check with a healthcare professional.
Can you take too much?
The recommended upper limit for calcium is 2,000 mg each day. Some studies suggest that too much calcium may increase the risk of prostate cancer and heart disease. But if you have high blood calcium levels, calcium in food or supplements probably isn’t the cause. Hypercalcemia is more likely to happen with health conditions like kidney disease, parathyroid disease, or cancer.
9. Vitamin D (ergocalciferol, cholecalciferol)
Vitamin D is sometimes called the sunshine vitamin. That’s because your skin makes vitamin D when it’s exposed to sunlight. Vitamin D helps to support healthy bones and muscles. It also improves your immune system, supports nerve health, lowers chronic inflammation, and helps to balance glucose levels.

Bowel disease
High alcohol intake
Type 2 diabetes
Magnesium supplements may interact with medications that treat osteoporosis, some antibiotics, diuretics, and stomach acid medication.
Can you take too much?
Magnesium in food isn’t a risk. But magnesium in supplements may lead to diarrhea. In fact, many laxatives contain magnesium as an active ingredient.

Have had weight-loss surgery
Have IBD
Drink high amounts of alcohol
Can you take too much?
Taking more than 40 mg a day in supplement form can lead to side effects. These include stomach upset, dizziness, headache, lower immune function, and cholesterol problems.
It’s also important to be aware that some denture creams contain zinc. Using them a lot may lead to zinc levels that are too high.
Other nutrients
Although they’re not vitamins or minerals, there are a few other nutrients worth mentioning when it comes to the health of older adults.
Essential fatty acids (omega-3 and omega-6)
Essential fatty acids, like omega-3 and omega-6, can help support memory and cardiovascular health. The best way to get essential fatty acids is in food. Fatty fish like herring and salmon are a great source. So are plant sources like flaxseed, walnuts, and vegetable oils.
The American Heart Association (AHA) recommends taking a supplement if you don’t get enough omega-3 fatty acids in your diet. The AHA also recommends fatty acid supplements if you have high triglycerides or are at risk of heart disease. But it’s best to talk with a healthcare professional before starting a supplement for this — especially if you take blood thinners or are at risk of bleeding.
Some studies suggest that taking more than 1 g every day could increase the risk of atrial fibrillation, an irregular heart rhythm. Avoid large doses in supplement form unless a healthcare professional prescribes it.
Protein
You lose muscle mass as you age. That can limit mobility and increase the risk of falls. So older adults need more protein to build and retain muscle mass.
Most experts recommend that older adults take in 1 g to 1.3 g of protein per every kilogram of body weight. Some ways to do this include eating foods like: meat, fish, lentils, eggs, Greek yogurt, almonds, and protein shakes.
Fiber
Fiber helps to:
Prevent constipation
Lower cholesterol
Decrease inflammation
Improve digestion and gut health
Lower the risk of some cancers and of diabetes
Foods that can help with your fiber intake include fruits, veggies, whole grains, beans, and nuts. Extra fiber is also available in many OTC supplements.
Water
It can be a challenge to stay hydrated as you get older. But water helps with:
Digestion
Muscle function
Thinking
Circulation
Kidney function
For people over 50 years, aim for 13 cups a day for men and 9 cups for women. That includes foods with a high water content like cucumber, lettuce, tomato, strawberry, and watermelon. Try keeping a water bottle with you throughout the day. Or jazz up your water intake with a splash of your favorite fruit juice. If you can, opt for one without added sugar.
Should I take a multivitamin or supplement?
The safest and healthiest way to get your vitamins or minerals is through the foods you eat. But older adults may have trouble absorbing enough vitamins through food. And you may take medications or have health conditions that affect the levels of important nutrients.
Studies with multivitamins and supplements are mixed in their results for different health outcomes. In general, research suggests that taking a multivitamin each day:
May help reduce the risk of cataracts and macular degeneration
May help to improve memory
May or may not lower the risk of heart disease and cancer
If you choose to take a multivitamin or supplement, it’s important to read and understand the label. Taking a supplement with a partial or total recommended daily allowance of vitamins and minerals may support your good health. But taking megadoses of vitamins probably isn’t worth the money. More importantly, in some cases, it can be dangerous. The best option is to talk with a healthcare professional about vitamin and mineral supplements that are right for you.
The bottom line
Your body needs many vitamins and minerals to function well. The best way to get these nutrients is with a well-balanced diet. But that’s not always possible. And sometimes age and different health conditions can affect how well your body absorbs the nutrients you take in. Taking a multivitamin or supplement may be an effective way to support your health. Talk with your primary care provider about how to find one that will work with your body, health conditions, and the medications you take.
