Vitamin D and Iron for Vegetarians and Vegans

Vitamin D and Iron for Vegetarians and Vegans

Nov 22, 2023Nicole Passante

As a vegetarian or vegan, it's important to pay attention to your nutrient intake to ensure you're getting all the essential vitamins and minerals your body needs. Two nutrients that often require special consideration for those following a plant-based diet are vitamin D and iron.

The Importance of Vitamin D

Vitamin D plays a crucial role in maintaining overall health. It helps regulate calcium and phosphorus absorption, supports immune function, and promotes bone health. While sunlight is the primary source of vitamin D, it can be challenging for vegetarians and vegans to obtain adequate amounts.

Plant-based sources of vitamin D include:

  • Mushrooms exposed to sunlight
  • Fortified plant-based milk
  • Fortified cereals
  • Supplements

It's important to note that vitamin D2, derived from plant sources, may not be as effective as vitamin D3, which is typically derived from animal sources. Therefore, it's recommended for vegetarians and vegans to monitor their vitamin D levels and consider supplementation if necessary.

The Role of Iron in a Plant-Based Diet

Iron is an essential mineral that plays a vital role in transporting oxygen throughout the body. While iron is abundant in many animal-based foods, vegetarians and vegans can still meet their iron needs through plant-based sources.

Plant-based sources of iron include:

  • Legumes (such as lentils, chickpeas, and beans)
  • Leafy green vegetables (such as spinach and kale)
  • Seeds and nuts (such as pumpkin seeds and almonds)
  • Whole grains (such as quinoa and brown rice)

Pairing iron-rich foods with vitamin C-rich foods can enhance iron absorption. For example, enjoying a spinach salad with a squeeze of lemon juice can help increase the amount of iron your body absorbs.

Optimizing Vitamin D and Iron Absorption

While plant-based sources of vitamin D and iron are available, there are a few additional steps you can take to optimize their absorption:

  • Ensure adequate stomach acid levels: Low stomach acid can hinder the absorption of iron. Consider incorporating apple cider vinegar or lemon water into your routine to support healthy digestion.
  • Avoid consuming calcium-rich foods with iron-rich foods: Calcium can inhibit iron absorption, so it's best to avoid consuming calcium-rich foods (such as dairy products) at the same time as iron-rich foods.
  • Consider cooking techniques: Some cooking techniques, such as soaking and sprouting legumes, can help reduce the presence of anti-nutrients that may interfere with iron absorption.


As a vegetarian or vegan, it's important to be mindful of your vitamin D and iron intake. While plant-based sources are available, monitoring your nutrient levels and considering supplementation if necessary can help ensure you're meeting your body's needs. By optimizing absorption through pairing foods strategically and supporting healthy digestion, you can thrive on a vegetarian or vegan diet.
