4 vitamin D-rich drinks that help strengthen bones.

Vitamin D has long been known as an important nutrient that helps the body absorb calcium effectively, maintain strong bones, and contribute to stable cardiovascular function. However, not everyone meets their daily vitamin D requirements, especially those who get little sun exposure.

Besides nutrient-rich foods like fatty fish, eggs, and dairy, several common beverages can also be convenient sources of vitamin D. Choosing the right drink can not only improve overall health but also help prevent many chronic diseases.

1. Some drinks are rich in vitamin D.

1.1. Milk fortified with vitamin D

Each 240 ml serving contains approximately 100–150 IU of vitamin D.

Since the 1930s, vitamin D has been added to cow's milk to help prevent micronutrient deficiencies in the community. According to the American Academy of Nutrition and Dietetics, while this addition is voluntary in the US, most cow's milk on the market is fortified with vitamin D to meet daily nutritional requirements.

According to the U.S. Dairy Council, fortified milk must provide a minimum of 100 IU and a maximum of 150 IU of vitamin D per 240 ml serving. For example, a glass of 1% fat milk might provide about 104 IU, which is nearly 17% of the daily vitamin D requirement.

Besides being rich in vitamin D, milk is also a source of many other important nutrients such as calcium, phosphorus, potassium, and protein, which help support bones, muscles, and energy metabolism. For those who are not used to drinking milk directly, it can be added to coffee or other beverages.

Compared to commercially produced creams (containing corn syrup or vegetable oil), milk is a healthier option and still ensures a delicious flavor, especially in coffee drinks like lattes or cappuccinos.

1.2. Nutritionally fortified plant-based milk

The vitamin D content is approximately 100–150 IU per 240 ml serving (depending on the brand).

Cow's milk isn't the only option for vitamin D supplementation. Many plant-based milks, such as soy milk, almond milk, cashew milk, rice milk, and pea milk, are now fortified with this micronutrient, making them suitable for vegetarians or those with lactose intolerance.

However, vitamin D supplementation in plant-based milk is not mandatory, so the levels can vary significantly between products. Some varieties may provide a similar amount of vitamin D to fortified cow's milk, while others contain almost none.

Therefore, when choosing plant-based milk, consumers should carefully read the nutrition label to ensure the product actually provides the necessary amount of vitamin D, avoiding the misconception that all plant-based milks have the same nutritional value.

1.3. Orange juice is fortified with vitamin D.

Each 240 ml serving contains approximately 100 IU of vitamin D.

Since the 1990s, orange juice has been fortified with vitamin D to help improve micronutrient deficiencies in the community. Currently, a glass of fortified orange juice can provide about 100 IU of vitamin D, equivalent to nearly 17% of the daily requirement.

According to nutritionist Emma Laing (University of Georgia), many fortified orange juices not only provide vitamin D but also contain significant amounts of calcium – a crucial element for maintaining strong bones. Depending on the product, one serving can provide more than 60% of the daily calcium requirement.

In addition, orange juice provides beneficial micronutrients such as vitamin A and vitamin E, which contribute to boosting immunity and protecting cells from oxidative stress. However, to optimize health benefits, it is advisable to prioritize products with low or no added sugar.

1.4. Mushroom broth – a natural plant-based source of vitamin D.

The vitamin D content is approximately 400–1,000 IU/100 g of ultraviolet (UV) treated mushrooms.

Mushrooms are one of the rare plant-based foods that can naturally provide vitamin D. When simmered to make broth, mushrooms can add a significant amount of vitamin D, especially if the ingredients are treated with ultraviolet light to increase the content of this micronutrient.

The nutritional value of mushroom broth depends on two main factors: whether the mushrooms have been UV-treated and the cooking method. Not all mushroom broths are equally rich in vitamin D. Some recent studies show that prolonged cooking time can reduce the amount of vitamin D in mushrooms. Therefore, when making your own mushroom broth, choose mushrooms that are clearly labeled as UV-treated and avoid simmering them for too long to preserve nutrients.

Adding mushroom broth to your diet not only boosts vitamin D but also provides additional antioxidants, supporting immunity and overall health.

2. How much Vitamin D should I supplement each day?

The recommended daily allowance (RDA) is approximately 600 IU/day for adults. The maximum safe limit is 4,000 IU/day for most adults.

Absorbing too much vitamin D from regular food is rare. In fact, vitamin D deficiency is far more common than excess. However, if supplements are used excessively, the risk of overdose can still occur.

Besides vitamin D-rich drinks, daily diet remains crucial. Foods naturally rich in vitamin D should be prioritized, including fatty fish such as salmon, trout, tuna, and sardines; as well as egg yolks, cheese, mushrooms, and fortified foods like yogurt and cereals.

It's important to note that vitamin D is a fat-soluble vitamin, so it's best consumed with healthy fats like olive oil, avocados, or nuts to increase absorption. Overall, incorporating a diverse range of foods and drinks, along with a healthy lifestyle (including adequate sun exposure), will help maintain optimal vitamin D levels for bone health, immunity, and cardiovascular health.

3. Things to note when consuming vitamin D-rich drinks.

Vitamin D-rich drinks can effectively support micronutrient supplementation, but to achieve optimal benefits and safety, the following points should be noted:

1. Check the nutrition label: Not all products are fortified with vitamin D. Read the content (IU/serving) carefully to ensure you are getting enough each day.

2. Avoid overuse: Although rare when consumed through food, excessive intake of vitamin D (especially from supplements) can still be harmful. It's best to stay within the recommended range and avoid self-administering high doses for extended periods.

3. Prioritize low-sugar products: Some drinks, such as canned orange juice or flavored milk, can contain a lot of sugar. Choose sugar-free or low-sugar options to avoid impacting your weight and cardiovascular health.

4. Combine with healthy fats: Vitamin D is a fat-soluble vitamin, so it should be taken with foods containing good fats (olive oil, avocados, nuts) to increase absorption.

5. Don't completely replace food: Drinks are only a supplement. A balanced diet is still necessary, including fatty fish, eggs, mushrooms, and other natural foods rich in vitamin D to ensure nutritional balance.

6. Note on cooking method: For dishes like mushroom broth, cooking for too long can reduce the vitamin D content. Cooking should be done moderately to retain nutrients.

7. Combine with a healthy lifestyle: In addition to diet, adequate sun exposure is still a natural way to help the body synthesize vitamin D more effectively.

Proper use of vitamin D-rich drinks can help boost bone health, immunity, and cardiovascular health without causing unwanted side effects.
