How Fortified Orange Juice Provides Vitamin D and Calcium for Strong Bones

Getting Your Vitamin D and Calcium from Fortified Orange Juice

Orange juice is a staple beverage for many people looking to start their day with key nutrients. While fresh-squeezed OJ naturally provides vitamin C, most store-bought orange juice also contains added vitamin D and calcium to make it an even more nutritious drink.

Vitamin D and calcium are crucial for building strong bones and supporting various body functions. Since many people fall short on their vitamin D and calcium intake, fortified orange juice can be a tasty way to help fill those gaps.

Let's take a deeper look at why vitamin D and calcium are vital, the benefits of getting these nutrients from fortified orange juice, and how much you need each day.

Importance of Vitamin D

Vitamin D is a unique vitamin because our bodies can synthesize it from sunlight. However, due to spending more time indoors, wearing sunblock outside, and living in northern latitudes, vitamin D deficiency is extremely common.

Vitamin D plays many crucial roles including regulating calcium absorption for bone health, supporting the immune system, neuromuscular function, cardiovascular health, mood, and more. Low levels are linked to osteoporosis, fractures, infections, diabetes, hypertension, depression, and certain cancers.

Since few foods contain natural vitamin D, consumption of fortified foods like cereals, dairy, eggs, mushrooms, and orange juice is recommended to prevent deficiency, especially during winter months.

Importance of Calcium

Calcium is the most abundant mineral in the human body, with 99% stored in the bones and teeth. Calcium is essential for bone mineralization and strength. It also enables proper muscle contraction, nerve transmission, and cardiovascular function.

Low calcium intake can cause osteopenia and osteoporosis decreasing bone density. This raises fracture risks as we age. Consuming adequate calcium rich foods is key for bone health throughout life as our skeletal calcium depletes with time.

Benefits of Vitamin D and Calcium Fortified Orange Juice

Drinking orange juice fortified with vitamin D and calcium offers unique advantages:

Convenient Combo

Rather than taking separate vitamin D and calcium supplements, fortified orange juice provides both key bone nutrients together in one beverage. This makes it easier to obtain sufficient quantities of each vitamin and mineral with simplicity.

Enhanced Absorption

The vitamin C naturally present in orange juice actually boosts absorption of the added vitamin D. Vitamin C helps convert vitamin D into its active form to enhance uptake. This synergy helps maximize the bone benefits.

Kid-Friendly Calcium Source

Many children don’t consume enough calcium rich foods like dairy and leafy greens. Vitamin D and calcium fortified orange juice offers a tasty, convenient way for kids and adolescents to get more of these bone-building nutrients.

Low Acidity

Orange juice tends to be less acidic than other citrus juices. This makes vitamin D and calcium fortified orange juice gentler on the stomach and teeth compared to grapefruit or lemon juice.

Added Immune Support

Beyond the vitamin D and calcium, orange juice also provides high levels of immune supportive vitamin C. One cup offers over 100% of the recommended daily vitamin C, which enhances immune cell function and acts as an antioxidant.

Selecting the Best Fortified Orange Juice

Not all fortified orange juices are equal when it comes to quality. Here are some tips for choosing an optimal vitamin D and calcium fortified orange juice:

Check the Label

Read nutrition labels and select a brand that includes at least 100 IU of vitamin D and 300mg calcium per serving. Avoid orange juices with excessive added sugars.

Stick to 100% Juice

Choose 100% pure orange juice rather than juice blends. You’ll get better nutrient absorption without unhealthy additives or sweeteners.

Refrigerated is Best

Refrigerated orange juice retains more vitamin C and flavonoids compared to shelf-stable varieties. Look for juices sold in the refrigerated section.

Consider Pulp Content

Pulp provides beneficial fiber but some dislike the texture. Choose pulp-free, some pulp, or high pulp based on your preference.

Watch for Fortificants

Check if the vitamin D used is D2 or D3. Opt for D3 which is more absorbable. Calcium citrate is generally better absorbed than calcium carbonate.

Avoid Excess Processing

Minimally processed juices without added flavorings or thickeners provide superior nutrition. Steer clear of juices “made from concentrate”.

How Much Vitamin D and Calcium Do You Need?

The daily recommended intakes for vitamin D and calcium depend on your age and health status:

Vitamin D Needs

• 600 IU daily for ages 1 – 70 years old
• 800 IU for those over 70 years old
• Higher doses may be recommended if deficient

Calcium Needs

• 1,000 mg daily for ages 19 – 50 years old
• 1,200 mg for ages 51 – 70 years old
• 1,200 – 2,000 mg for teens and elderly over 70

Consuming 1 – 2 cups of fortified orange juice daily can help meet a substantial portion of your vitamin D and calcium needs. Those with lactose intolerance or difficulty absorbing calcium may especially benefit.

Maximizing the Bone Benefits of Fortified Orange Juice

While vitamin D and calcium fortified orange juice provides key nutrients, your diet and lifestyle also impact bone health. Follow these tips as well:

• Perform regular weight-bearing and muscle-strengthening exercises
• Maintain a healthy BMI to reduce bone turnover
• Eat a balanced diet with fruits, vegetables, lean proteins
• Limit sodium, caffeine, and alcohol which deplete calcium stores
• Don’t smoke, as chemicals interfere with absorption
• Consider supplements if blood tests show major deficiencies

Drinking fortified orange juice is not a magic bullet, but can be part of an overall bone-supportive nutrition and lifestyle plan.

Safety and Side Effects

Orange juice fortified with vitamin D and calcium is typically safe when consumed in moderation as part of a healthy diet. However, some considerations include:

• May interact with some medications like diuretics, steroids or blood pressure drugs
• Not recommended for those with kidney disease due to calcium levels
• Higher amounts may cause constipation or kidney stones
• Can irritate gastroesophageal reflux disease (GERD)
• Always discuss fortified juice intake with your doctor if concerned

Pregnant women should avoid unpasteurized juice due to foodborne illness risk. Otherwise, fortified orange juice can help pregnant and breastfeeding women meet higher calcium needs.

A Tasty Way to Bone Up

Drinking orange juice fortified with bone-supporting vitamin D and calcium is an easy way to help reduce risk of osteoporosis and fractures. Choose a high-quality refrigerated juice without excess sugars or additives to reap the most nutritional rewards from each refreshing glass.
