Sources of Vitamins That Support Everyday Health & Nutrition
Vitamins are organic molecules that are needed for proper body function. Most vitamins must be obtained through the diet because the body cannot produce sufficient quantities to meet its needs. Some vitamins are also fat-soluble, which means they must be consumed with fat to be absorbed. These include vitamins A, D, E, and K.
For some vitamins, meats, oils, and dairy products can be better sources of vitamins than leafy vegetables and fruits, as their fat content supports vitamin absorption. Read on to explore some of the best dietary sources of vitamins and understand how they can help meet your daily nutritional needs.
Note: For fat-soluble vitamins (A, D, E, and K), consuming foods with dietary fat can support absorption. The best food source depends on the specific vitamin.
What are the Plant-Based and Animal-Based Sources of Vitamins?
Vitamins have different plant-based and animal-based sources. The table below showcases the vitamins' names along with sources of vitamins.
| Vitamins Name | Plant-Based Source | Animal- Based Source |
| Vitamin A | Leafy vegetables such as spinach, carrots, and fruits such as mango, papaya and apricots | Dairy products like cheese, milk and yoghurt, eggs, fatty fish such as salmon fish |
| Vitamin B | Peas, fresh fruits, multigrain bread | Meat, fish, eggs and dairy products |
| Vitamin C | Citrus fruits, broccoli, sprouts, blackcurrant, potatoes | No animal-based source contains vitamin C |
| Vitamin D | Mushrooms | Oily fish like salmon, red meat, egg yolk |
| Vitamin E | Plant oils like soya oil, nuts and seeds, wheatgerm | Fish like salmon, lobsters |
| Vitamin K | Green leafy vegetables such as broccoli and spinach, vegetable oils, cereal grains | Dairy products and meat |
Which 10 Foods Are the Best Sources of Vitamins?
Now that you know about the main sources of vitamins, you must be wondering “what are the natural sources of vitamins?” Well, the following are the 10 best food sources of vitamins:
1. Nuts
Nuts are filled with vitamins, minerals, fibre and antioxidants. These include Vitamins B1, B2, B6, and E. Nuts are a heart-healthy, cholesterol-lowering snack. Nuts are considered protein-rich foods and are often grouped with seeds, eggs, legumes, and meats in dietary guidance. For example, Almonds are a source of magnesium, calcium and folate.
One ounce of almonds provides a substantial proportion of the recommended daily intake of vitamin E. And most of the fat in almonds is mainly monounsaturated fatty acids. This type of fat, unlike saturated fat, is linked to heart health.
2. Berries
Berries are a great source of vitamins and contain vitamin K. This vitamin supports cellular function of the body, also contributes to normal blood clotting and plays a role in bone health. Vitamin K works together with manganese, which is mostly found in blueberries. Berries are a low-calorie source of fibre and vitamin C.
Berries like blueberries also contain anthocyanins, plant compounds that have been studied for their potential role in supporting cognitive health. About 3/4 cup of fresh berries such as blueberries contains 2.7 grams of fibre and 10.8 milligrams of vitamin C.
3. Green leafy Vegetables
Leafy Greens are a good source of essential vitamins. These include Vitamins A, B2, B3, B6, B9, C, E, K, and Beta-Carotene. Vegetables like broccoli are cruciferous vegetables, which are considered a source of vitamin A, which supports healthy vision. It may also contain vitamin C, which helps the body absorb more iron.
Some leafy vegetables, including spinach, may have vitamins A and C, potassium, carotenoids and folate. Some of the carotenoids found in spinach are beta carotene, lutein and zeaxanthin. These phytonutrients may help support healthy vision and proper functioning of the body's cells.
4. Fish
Fish are generally considered a good source of vitamins. These include Vitamins A, B1, B2, B3, B5, B6, B12, D, and E. Fish like Salmon are generally known for their omega-3 fatty acids. They contain omega-3 fatty acids such as EPA and DHA, which contribute to several normal body functions and have been studied for their role in heart and brain health. Salmon can be used fresh or canned.
Fish such as tuna and trout provide several vitamins and nutrients, including B vitamins and vitamin D.
5. Meat
A key provider of vitamin B12 in standard diets is meat. Specifically, organ meats such as liver pate and liver sausage offer abundant vitamin A alongside iron, whereas poultry like chicken breast supplies significant amounts of niacin and vitamin B6.
Studies suggest that 100 grams of red meat may provide around 25% of the recommended daily allowance (RDA) for riboflavin, niacin, vitamin B6 and pantothenic acid, and two-thirds for vitamin B12.
6. Mushrooms
Incorporating mushrooms into your diet may help you get crucial sources of vitamins, particularly Vitamin D, along with vitamins B like B2, B3, and B5. These nutrient-dense fungi stand out as versatile food sources of vitamins that may support your overall daily nutritional intake.
Portobello, cremini, and shiitake mushrooms are among the types of mushrooms that are low in calories and carbohydrates but rich in vitamins.
7. Eggs
Eggs are considered a good source of vitamins, minerals, high-quality protein, and healthy fats. Eating one large egg provides essential nutrients such as B12, B2, A, B5, and selenium. Additionally, they may serve as natural sources of vitamins such as E and folate, alongside vital minerals that may include calcium, iron, and zinc.
Eggs provide numerous sources of vitamins that may support your body's daily nutritional requirements. Studies have shown that egg yolks can contribute to dietary intake of carotenoids such as lutein and zeaxanthin.
8. Wheat Germ
Whole grains are foods like oats, popcorn and brown rice, where all the edible parts such as bran, endosperm and germ of the grain are still present. Each part would help a new plant grow if the grain was planted. The germ is where a new plant sprouts, and it contains vitamins, minerals, antioxidants and some fats.
Wheat germ is considered an excellent source of thiamin, and a good source of vitamins such as folate, niacin and Vitamin E.
9. Sweet Bell Peppers
Bell peppers are generally considered a good source of essential vitamins. Bell peppers are mostly rich sources of Vitamin C, which supports overall health. Incorporating vibrant red and yellow varieties provides higher concentrations of essential nutrients such as beta-carotene and lycopene.
You may add these colourful vegetables to your diet as a simple and effective way to consume them as a vital source of vitamins.
10. Sweet Potatoes
Sweet potatoes have a deep orange-yellow colour which signifies the presence of antioxidants known as carotenoids. One of the most well-known is beta-carotene. It is a substance the body can use to make vitamin A, and it helps cells manage day-to-day wear and tear.
Sweet potatoes are a source of potassium and vitamin A. Sweet potatoes may also contain vitamin B. And like many vegetables, they are also a good source of fibre.
