Our B-Vitamin Guide for Older Adults (Plus 11 Food Sources)

The eight B-group of vitamins work as a team to keep you in optimal health. They include:

  • Thiamin (also known as vitamin B1)
  • Riboflavin
  • Niacin
  • Vitamin B5 (also known as pantothenic acid)
  • Biotin
  • Vitamin B6
  • Folate
  • Vitamin B12

B-vitamins not only play a critical role in keeping our brains healthy, they also help convert food into fuel for energy, keeping our metabolism humming and our cardiovascular system strong.

Important B-Vitamins for Older Adults

1. Vitamin B12

Of all the B vitamins, B12, which is important for red blood cell production and maintaining healthy brain and nerve function, gets the most notoriety. Vitamin B12 can only be found in animal products, including meat, fish, eggs and dairy. As we age, our bodies lose some of their ability to absorb this vitamin. If you take Metformin for diabetes, or use drugs to control stomach acid, such as Prilosec or Pepcid, be aware that they interfere with vitamin B12 absorption. The current recommended daily allowance for B12 is 2.4 micrograms, but some nutritionists believe that the intake minimum should be increased.

2. Folate

Folate is a water-soluble B vitamin that’s naturally found in a variety of foods, especially dark green leafy vegetables. The Office of Dietary Supplements at the National Institutes of Health recommends adults aim to intake 400 micrograms of folate every day (the equivalent of 0.4 milligrams). A folate deficiency negatively impacts the nervous system and can also result in anemia. Folate is important to maintain a healthy nervous system and there’s growing evidence that a lack of folate can affect mood and cognitive function in older adults.

3. Thiamin (also known as vitamin B1)

Thiamin is critical for forming adenosine triphosphate (ATP), the energy source for every cell of the body. A vitamin B1 deficiency is rare; however, alcoholism, Crohn disease and kidney dialysis can cause a deficiency. Symptoms of a vitamin B1 deficiency include headache, nausea, fatigue, irritability, depression or abdominal discomfort. You may also have trouble digesting carbohydrates, which can allow pyruvic acid build up, causing a loss of mental alertness, difficulty breathing and heart damage. The recommended daily intake for vitamin B1 is 1.1 milligrams for women and 1.2 milligrams for men.

4. Vitamin B5 (also known as pantothenic acid)

The chemical name for vitamin B5 is Pantothenic acid, from a Greek word meaning “everywhere,” indicating its availability in a wide variety of foods. This vitamin helps manufacture red blood cells and is important for hormone production and cholesterol synthesis. Symptoms of a vitamin B5 deficiency include fatigue, insomnia, depression, irritability, vomiting, stomach pains, burning feet, and upper respiratory infections.

11 Food Sources of Vitamin B

B-vitamins are water soluble, meaning that our bodies cannot store them, so it’s important to replenish our supplies frequently and get our B-vitamins from fresh meats, vegetables and whole unprocessed grains. B-vitamins are also fragile. Processing, extended cooking and storage, as well as alcohol, destroy B vitamins.

Here’s a list of foods that are a good source of B-vitamins.
