Vitamin D Foods: List of the Top 10 Foods High in Vitamin D

Best 10 Vitamin D Rich Foods

Vitamin D is one of several fat-soluble vitamins. It is unique from other vitamins since the body can make its vitamin D from sunlight exposure. 

Vitamin D has additional roles in the human body besides being a nutrient. There are a few vitamin D foods that are very high in the vitamin.

It is a prohormone and regulates hormones and the immune system. Unless the food is fortified with vitamin D, it is typically a poor source of the vitamin. Vitamin D is also essential for the bones because it helps with calcium absorption.

Deficiencies in vitamin D can cause problems with the skeletal system, mainly the softening of bones (osteomalacia) or abnormalities in bone development (rickets). Symptoms of vitamin D deficiency can be subtle or vague and may go unnoticed without blood work specifically to check levels.

The Symptoms of Vitamin D Deficiency May Include:

  • Decreased immune system function (increased vulnerability to pathogens);
  • Seasonal depression (seasonal affective disorder);
  • Autoimmune diseases;
  • Cancer;
  • Low-grade decreases in bone density (osteopenia);
  • Dermatologic conditions (psoriasis or eczema);
  • Dementia.

Those most vulnerable to vitamin D deficiencies are people who live in regions with less sunlight exposure (northern areas), people with deeper skin tones, individuals who eat low-fat diets, and people who take weight loss medications or steroids (corticosteroids).

Vitamin D aids in cell replication and may have a role in the development of autoimmune diseases. The Recommended Daily Allowance (RDA) for vitamin D is 600 international units (IU) daily. The Daily Value (DV) is 400 IU/day.

Top 10 Vitamin D Foods Rich Sources with Their RDAs and DVs

  • Sunlight - Vitamin D is synthesized from cholesterol in the skin.
  • Cod liver oil (1 tsp) - 440 IU (over 100% DV)
  • Salmon (3 oz) - 400 IU (100% DV)
  • Mackerel (3oz) - 400 IU (100% DV)
  • Tuna (3 oz) - 228 IU (57% DV)
  • Sardines (3 oz) - 164 IU (41% DV)
  • Raw milk (1 cup)- 98 IU (24% DV)
  • Eggs (1 large)- 41 IU (10% DV)
  • Caviar (1 oz)- 33 IU (8% DV)
  • Mushrooms (1 cup)- 2 IU (1% DV)

In addition to acquiring vitamin D from sunlight, eat two sources of vitamin D rich foods each day.

Major Health Benefits of Adequate Vitamin D Doses

1) Better Weight Management

Deficiencies in vitamin D are related to obesity and difficulties losing excess weight. According to one study, women with higher levels of vitamin D who ate a calorie-controlled diet lost more weight than women who were vitamin D deficient but ate a diet with comparable calories.

Currently, it is not clear whether vitamin D deficiency contributes to obesity or obesity contributes to the deficiency. The overall message is, if you are struggling to lose weight, you may want to have your vitamin D levels checked.

2) Nervous System Function and Cancer

According to study results, people with lower vitamin D levels tend to perform poorly on standardized tests, have worse decision-making skills, and experience difficulties on tasks that require more attention and focus.

Also, studies have shown that adequate vitamin D levels can reduce the risk of cancer, especially breast and colorectal cancers.

3) Improved Bone and Muscle Health

Consuming foods rich in vitamin D is critical for calcium absorption and improves bone strength and density. Vitamin D may play a role in maintaining healthy muscles.

Older adults who have adequate vitamin D intake tend to be more active, have better muscle strength, and are less likely to experience falls.
