How to get calcium and vitamin D without dairy

How Vitamin D Works in the Body

Vitamin D plays a key role in helping the body absorb calcium efficiently and maintaining healthy bones and muscles. It ensures calcium from food is absorbed and helps regulate the balance between bone building and breakdown. This is especially important for individuals who avoid dairy products due to lactose intolerance.

Lactose Intolerance and Vitamin D Deficiency Risk

For those with lactose intolerance, avoiding fortified dairy products can lead to a lower intake of vitamin D. Many lactose-intolerant adults miss out on this nutrient when they skip dairy. Using lactase supplements, such as milktab, can help digest dairy and provide access to this important nutrient.

Health Effects of Low Vitamin D

A deficiency in vitamin D can lead to several health problems, including:

• Weakened bones, which increases the risk of fractures
• Reduced muscle function, making falls more likely
• Compromised immune response, leading to a higher chance of infections

Getting enough vitamin D is crucial for proper calcium absorption and utilization, supporting bone strength and overall health.

Required Daily Vitamin D Amounts

Getting enough vitamin D is especially important for lactose intolerant adults to maintain their health.

Standard Daily Requirements

In the U.S., adults aged 19–70 are advised to consume 600 IU (15 mcg) of vitamin D daily. For those over 70, the recommended intake increases to 800 IU (20 mcg). These amounts are key for supporting bone health and immune function.

Lactose intolerant individuals may need to take extra steps to meet these recommendations.

Tips for Lactose Intolerant Adults

Here are some practical ways to meet vitamin D needs without relying on traditional dairy:

• Fortified non-dairy products: Look for foods like fortified orange juice, cereals, and plant-based milks that are enriched with vitamin D.
• Use lactase supplements: Products like milktab can help digest dairy, allowing you to benefit from its vitamin D content.
• Combine multiple sources: Balance your intake with a mix of sun exposure, fortified foods, supplements, and limited dairy consumption (with the help of lactase).

Your specific needs may depend on factors like skin tone, geographic location, diet, and overall health. Regularly checking your vitamin D levels can help ensure you’re on track.

Getting Vitamin D Without Dairy

If you're lactose intolerant, you can still meet your daily vitamin D needs through non-dairy sources.

Food Sources

Plenty of non-dairy foods naturally contain vitamin D or are fortified with it. Here's a quick breakdown:

Fortified plant-based options can provide vitamin D levels similar to dairy products. Be sure to check the nutrition labels, as the vitamin D content can vary by brand.

Pair these dietary sources with safe sun exposure to further support your vitamin D intake.

Sun Exposure Guidelines

Sunlight is the most effective way for your body to produce vitamin D. However, it's important to balance sun exposure and skin protection.

General exposure recommendations:

• Light skin: 10-15 minutes of midday sun
• Medium skin: 15-20 minutes of midday sun
• Dark skin: 20-30 minutes of midday sun

Aim for this exposure 2-3 times a week without sunscreen initially. Several factors can influence how much vitamin D your skin produces:

• Location: People living above 37° latitude (e.g., north of San Francisco or Richmond, VA) may get limited UVB exposure during winter months (November through March).
• Time of day: UVB rays are strongest between 10 AM and 3 PM.
• Season: Summer months are the most efficient for vitamin D production.
• Cloud cover: Clouds can block up to 50% or more of UVB rays.

After your recommended sun exposure, apply sunscreen with SPF 30 or higher to protect your skin.

Vitamin D Supplements

Signs You Might Need Them

Certain factors can indicate a need for vitamin D supplements, especially if you're lactose intolerant. Here are some common signs:

• Limited sun exposure: Spending most of your time indoors during daylight hours or living in northern areas with less sunlight.
• Darker skin tone: Higher melanin levels can reduce your skin's ability to produce vitamin D from sunlight.
• Age over 50: Aging skin becomes less efficient at synthesizing vitamin D.
• Higher BMI: Excess body fat can trap vitamin D, making it less available for your body to use.
• Digestive problems: Issues like celiac disease or Crohn's can interfere with nutrient absorption.
• Bone or muscle pain: These could be linked to a deficiency.
• Seasonal depression: Often connected to lower vitamin D levels during darker months.

If you notice these signs, it might be time to consider a supplement. Here's how to choose the right one.

Choosing the Right Vitamin D Supplement

Once you've identified a potential deficiency, follow these tips to pick an effective supplement.

Choosing the Right Type and Dose

• Opt for vitamin D3 (cholecalciferol) instead of D2, as it’s absorbed more efficiently.
• For general maintenance, start with 1,000–2,000 IU daily.
• If you have a severe deficiency, higher doses (4,000–5,000 IU) may be necessary, but only under a doctor’s guidance.

What to Look For

• Products with third-party certifications like USP or NSF to ensure quality.
• Clear and accurate dosage information on the label.
• Allergen-free options if you have sensitivities.
• Gelatin-free supplements if you're vegetarian or vegan.

Storage and Absorption Tips

• Store your supplements in a cool, dry place, away from direct sunlight.
• Take them with a meal containing some fat to improve absorption.
• Check expiration dates to ensure potency.
• If you have trouble swallowing pills, consider liquid forms for easier absorption.

Managing Your Vitamin D Levels

Keeping your vitamin D levels in check is especially important if you're lactose intolerant. A mix of regular testing and smart dietary choices can help you maintain healthy levels.

Blood Level Testing

To track your vitamin D levels effectively, consider the following:

• Frequency: Test every 6–12 months, or more often if you're managing a deficiency.
• Ideal range: Aim for 30–50 nanograms per milliliter (ng/mL).
• Test type: Use a 25-hydroxy vitamin D test.
• Timing: Test during the same season each year to account for natural changes.

Your healthcare provider can help interpret your results and guide you on any necessary supplementation.

Using Lactase Enzymes for Dairy

For those with lactose intolerance, lactase enzymes can make it easier to consume dairy products, which are often fortified with vitamin D. A product like milktab is a reliable option for supplementing lactase enzymes.

Here’s how to use lactase supplements effectively:

• Take the enzyme supplement right before eating or drinking dairy.
• Choose dairy products fortified with vitamin D to get the most benefit.

These steps can help you safely include more vitamin D-rich foods in your diet.

Summary

This section highlights key strategies to help lactose-intolerant individuals maintain healthy vitamin D levels.

Keeping vitamin D levels in check is especially important for adults with lactose intolerance. Achieving this balance involves regular testing and thoughtful dietary adjustments.
