The Benefits of Taking Vitamin D and B12 Together

Vitamin D and B12 are both crucial components that play a key role in our overall well-being. While taking them together isn’t a secret key to the elixir of life, combining these nutrients will help your immune system, keep your bones strong, and help support your overall energy levels. Because of this, you’ll often see supplements merge these two vitamins.

Typically, it’s best to try to get whatever vitamins and minerals you can from your diet - but it’s hard to reach optimal levels on a daily basis. This is especially true with vitamin D3 and B12; many suffer from malabsorption of B vitamins without recognizing it, while vitamin D isn't abundant in a typical diet. 

In this article, we’ll go over why you might need to supplement these vitamins and the vital role they play together in your health.

Understanding Vitamin D and B12

Vitamin D, known as the “sunshine vitamin,” is vital for bone health, immune system support, and calcium absorption. It is primarily obtained through sun exposure, but can also be found in certain foods and dietary supplements. 

On the other hand, Vitamin B12 is essential for red blood cell formation, nerve health, and energy production. It is predominantly found in animal-based foods and fortified products.

Taking Vitamin D and B12 together can provide a synergistic effect, enhancing their individual benefits. While Vitamin D supports bone health and immune function, Vitamin B12 aids in energy metabolism and nervous system health. Together, they can help improve overall energy levels, mood, and immune system health, making them a powerful combination for maintaining optimal health.

Can You Take Vitamin D and B12 Together?

For many people, the world of vitamins can seem puzzling. With so many options, it’s easy to wonder how specific vitamins interact and whether they should or shouldn’t be taken together. One common question is about taking Vitamin D and B12 together. The answer? Absolutely! These two vitamins can complement each other to boost your overall health. Vitamin D supplements are particularly important for enhancing overall health, including bone strength, immune function, and energy levels.

Because Vitamin D and B12 are absorbed differently (Vitamin D is fat-soluble while B12 is water-soluble), you might find conflicting information on the best way to take these supplements. We find that both these supplements can be best taken with food - to avoid an upset stomach. Although, if you are prescribed higher doses of B12 by a medical provider for a deficiency, you might be instructed to take it on an empty stomach to try and maximize absorption.  

What is Vitamin D?

Vitamin D helps support calcium absorption, which makes it essential for maintaining bone health. It’s one of the fat-soluble vitamins, which means it is absorbed along with fats in the diet. (AKA - typically you should take it with food)

Your body naturally produces Vitamin D when exposed to the sun, though production is dependent on a variety of factors like skin pigment, UV levels, seasons and geography. You can also find Vitamin D in a few foods like fatty fish (salmon), egg yolks, and fortified foods like cereal and milk.

Because of it’s lack in a typical diet, Vitamin D supplements are key - especially in winter months or if you have limited sun exposure.

 

Benefits of Vitamin D

The benefits of Vitamin D extend beyond just supporting healthy bones. It plays a critical role in:

• Enhancing calcium absorption: Essential for strong bones and teeth, Vitamin D helps the body absorb calcium effectively.

• Supporting the immune system: Helps fight off infections.

• Promoting mood regulation: Linked to reducing symptoms of depression.

• Supporting muscle function: Vital for muscle health and performance.

Why Take Vitamin D?

Given its multiple roles in maintaining health, ensuring adequate Vitamin D intake is crucial for:

• Preventing bone diseases like osteoporosis.

• Supporting overall immune health, especially during cold and flu seasons.

• Enhancing physical performance and muscle strength.

• Boosting overall mood and energy levels.

Symptoms of Vitamin D Deficiency

Lack of Vitamin D may result in several health issues, such as:

• Weak and brittle bones or frequent fractures.

• Fatigue and low energy levels.

• Increased susceptibility to infections.

• Mood changes, including symptoms of depression.

Extreme or prolonged deficiency can contribute to conditions such as osteoporosis or rickets.

What is Vitamin B12?

Vitamin B12, or cobalamin, is a nutrient that is used for nerve tissue health, brain function, and red blood cell production. It’s most commonly found in animal-based foods and fortified products.

Benefits of Vitamin B12

• Supports nerve health

• Aids red blood cell formation and prevents anemia

• Promotes brain health

• Boost energy levels

Why Take Vitamin B12?

Vitamin B12 is a common deficiency among adults. Supplementing with Vitamin B12 is particularly important for individuals who:

• Follow a vegan or vegetarian diet, as plant-based foods generally lack B12.

• Experience absorption issues due to gastrointestinal conditions.

• Are older adults, as absorption decreases with age.

Symptoms of Vitamin B12 Deficiency

• Fatigue and weakness.

• Neurological changes, such as numbness and tingling in the hands and feet - also called neuropathy.

• Memory loss or cognitive decline.

• Mood disturbances, such as depression or irritability.

Vitamin D3 & Vitamin B12 Together

Combining Vitamin D3 (a potent form of Vitamin D) and Vitamin B12 can enhance their individual benefits. Together, they support:

• Overall energy levels: While B12 converts food into energy, Vitamin D enhances muscle function.

• Mood and mental health: Both vitamins are linked to improved mood and cognitive health.

• Immune system support: They work collectively to bolster the body's defenses against infections.

How to Ensure Adequate Vitamin Intake

To maintain proper levels of Vitamin D and B12, consider:

• Dietary sources: Include fatty fish, eggs, dairy products, and fortified foods in your diet.

• Sun exposure: Aim for 10-30 minutes of sunlight several times a week, depending on your skin tone and location.

• Supplements: Consider high-quality supplements, especially if dietary intake may be insufficient.

Not all supplements are created equal. Their effectiveness varies based on ingredient quality, formulation, and manufacturing practices. Choose supplements from reputable sources that follow strict testing and quality standards.

How much Vitamin D and B12 should I take? 

The recommended dosage for Vitamin D and B12 can vary based on individual needs, age, lifestyle, and existing health conditions.

Vitamin D:

• Adults: between 600 to 800 International Units (IU) per day.

• Older Adults: Those over 70 years may need closer to 800-1000 IU daily

Vitamin B12:

• Adults: approximately 2.4 micrograms (mcg) per day. This requirement might increase for pregnant or breastfeeding women.

• Individuals with Absorption Issues: Higher doses, often in the form of injections or supplements ranging from 500 mcg to 1,000 mcg, might be necessary.

Always discuss with a healthcare provider before beginning any new supplement regimen to tailor recommendations to your specific needs and avoid unnecessary risks of over-supplementation.

Can you take too much Vitamin B12 and D? 

Because Vitamin D and B12 are water-soluble and stored in the body, it is unlikely to experience toxicity from high doses. That being said, excessive intake could lead to unwanted side effects or interactions with other medications.

Can I take Vitamin B12 and D on an empty stomach? 

Yes, both Vitamin B12 and D can be taken on an empty stomach without any adverse effects. However, these two vitamins do absorb differently as Vitamin D is fat-soluble while Vitamin B12 is water-soluble.

• Fat-soluble: Best taken with food

• Water-soluble: Best taken on an empty stomach

However, the most important part of timing to take supplements is actually taking them! Choose a routine that best fits your lifestyle and will keep you consistent.  

What is the best time to take Vitamin D and B12?

The best time to take Vitamin D and B12 may vary based on individual needs and preferences. Some people prefer taking them in the morning with breakfast, while others find it more convenient to take them at night before bed. 

It's important to follow any specific recommendations from your healthcare provider or supplement manufacturer for optimal absorption and effectiveness.
