The importance of vitamins

It’s never too soon to start thinking about healthy aging and building nutritious habits, says Angel Planells, a dietitian who specializes in aging and gerontology and former president of the Washington State Academy of Nutrition and Dietetics. Planells shares five vitamins for seniors and how to obtain them through natural, delicious sources that could help fight a variety of ailments, including memory disorders.
“Consuming a wide variety of foods will improve your chances of getting all vitamins naturally through your diet,” Planells says. If your parent is considering taking a vitamin or multivitamin, they should meet with a registered dietitian or doctor first, he says, because “there could be drug-nutrient interactions, medications, and competing factors that may increase or decrease absorption.”

Vitamin A benefits: Bone development, healthy skin, and more

Vitamin A stands out as one of the most important vitamins for seniors because it promotes bone health.
Having a sufficient amount of vitamin A could help prevent bone issues, such as hip fractures. A 2015 study of more than 5,000 men and women 55 and older found those with a sufficient vitamin A intake had a significantly lower risk of fractures.
The right amount of vitamin A can also help fend off osteoporosis, a bone disease that causes bones to become brittle. According to the Bone Health and Osteoporosis Foundation, osteoporosis and low bone mass affects an estimated 54 million Americans ­— one in two women and one in four men 50 and older may experience bone injuries because of osteoporosis.
In addition, vitamin A may help you see better at night. It produces rhodopsin, a photo pigment found in the part of the retina associated with night vision.
Vitamin A also benefits your largest organ — your skin. It boosts hydration and repairs damaged skin, such as bruises.

Incorporate these natural vitamin A sources into your diet

Take advantage of the following vitamin A sources:
  • Beef liver: 6,582 micrograms (mcg)
  • Ricotta cheese: 263 mcg
  • Carrots: 459 mcg
  • Spinach: 573 mcg
  • Sweet potato: 1,403 mcg
The recommended daily vitamin A intake is 700 mcg for women and 900 mcg for men.

Vitamin B benefits: Boosting metabolism and energy

“B vitamins play a role in maintaining optimal health and well-being,” Planells says. “The B vitamins have an impact on your energy levels, brain function, and cellular metabolism.”
Vitamin B assists in converting food to glucose, which provides energy. Similarly, the eight B vitamins metabolize carbohydrates, proteins, and fats. Vitamin B deficiency can lead to excessive thirst, diarrhea, and blurry vision, Planells says.

Take advantage of nutritious vitamin B foods

Pack your plate with these delicious, dietary sources of vitamin B2 (or Riboflavin):

  • Breakfast cereals: 1.3 mg
  • Oats: 1.1 mg
  • Yogurt: 0.6 mg
  • Portabella mushrooms: 0.3 mg

  • Vitamin B6: 1.5 mg for women, 1.7 mg for men
  • Vitamin B12: 2.4 mcg for both women and men

Vitamin C benefits: Fighting infection and common health problems

Most of vitamin C’s power comes from its ability to enhance immune defense — it’s commonly touted as a treatment for everything from high blood pressure to a cold. The vitamin helps produce much-needed white blood cells to fight sickness and infection. Due to this important function, vitamin C benefits also include helping wounds heal and producing collagen. Additionally, vitamin C facilitates the body’s iron absorption, making it a good vitamin for seniors.
“People with vitamin C deficiencies may develop scurvy, which resembles tiredness, weakness, irritability, weight loss, and muscle aches,” Planells says.

Vitamin C foods for your immune system

Make creative meals with the following dietary vitamin C sources:
  • Brussels sprouts: 48 mg
  • Red pepper: 95 mg
  • Cauliflower: 26 mg
  • Strawberries: 49 mg
  • Tomatoes: 17 mg
The recommended daily vitamin C intake is 75 mg for women and 90 mg for men.

Vitamin E benefits: Strengthening your immune system

Vitamin E is an antioxidant, meaning it protects cells from damage. Vitamin E strengthens the immune system and promotes a healthy nerve system. A 2019 study in Circulation Research, the journal of the American Heart Association, suggests that long-term vitamin E intake may be beneficial for your loved one’s health.
