After a certain age, many of us lack two vital nutrients: vitamin K2 and D3. Vitamin D helps regulate calcium levels in the blood, while vitamin K is essential for proper bone formation and mineralization. 

Vitamin D3 and K2 work synergistically to enhance the absorption and utilization of calcium in the body. They play a key role in overall bone health and may help reduce the risk of chronic diseases such as heart disease and osteoporosis.

Incorporating these nutrients into our daily routine through supplements is important since sunlight alone can’t provide enough vitamin D3+K2.

However, not all brands on the market offer pure and effective supplements. After testing over 50 supplements, we’ve handpicked the 7 best Vitamin D3 and K2 supplements of 2024.

What Are Vitamin D3 and K2 Supplements?

Vitamin D3 and K2 are two essential nutrients that play important roles in maintaining overall health. 

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that is naturally synthesized in our bodies when our skin is exposed to sunlight. It is involved in numerous functions, such as promoting bone density, boosting the immune system, supporting cardiovascular health, and regulating mood. However, many people do not get enough sunlight exposure or have conditions that hinder the body’s ability to produce sufficient Vitamin D3, making supplementation necessary.

Vitamin K2 is another fat-soluble vitamin that is important for proper blood clotting, bone health, increasing bone density, and cardiovascular health. It works synergistically with Vitamin D3, as it plays a crucial role in directing calcium to the bones and teeth while preventing it from depositing in the arteries and soft tissues. Without sufficient Vitamin K2, calcium can accumulate in the wrong places, leading to health issues such as arterial calcification and osteoporosis.

Combining Vitamin D3 and K2 in a supplement offers several benefits, all of which we’ve discussed.

Benefits Of Vitamins D3 and K2

Benefits of D3 Vitamin:

Vitamin D, often referred to as the “sunshine vitamin” due to its natural production from sunlight (UVB rays), comes in various forms, with vitamin D3 being the most effective for absorption. Vitamin D1, once considered a single compound, is now obsolete, while vitamin D2, found in plants, is more cost-effective but less potent than D3.

Vitamin D3, also known as cholecalciferol, is recognized for its effectiveness in raising vitamin D levels and aiding calcium absorption, contributing to strong bones. 

Other benefits include:

  • support for the immune system
  • prevention of gastrointestinal diseases
  • cardiovascular health improvement 
  • brain health enhancement 
  • mood improvement

Benefits of K2 Vitamin:

Vitamin K is a fat-soluble vitamin that occurs in two forms: K1 and K2.

Vitamin K1, also known as phylloquinone, is commonly found in leafy greens like spinach and kale. However, despite being a significant part of our dietary vitamin K intake (up to 90%), K1 is poorly absorbed by the body. 

Vitamin K2, specifically in the form of menaquinone-7, is naturally produced in small amounts by gut bacteria and is present in animal products like fatty fish, grass-fed beef, and fermented foods such as natto. 

As a fat-soluble vitamin, vitamin K2 offers various health benefits, including 

  • Support for heart health 
  • Maintaining healthy bones 
  • Promoting strong teeth
  • Supporting cognitive function
  • Contributing to neonatal health.

What To Look For When Buying Vitamin D3 With K2?

When it comes to buying the best K2 D3 supplement, there are several factors to consider to ensure you’re getting the best:

  • Quality and Purity

Prioritize quality and purity when selecting supplements by opting for reputable brands. Look for products that undergo third-party testing for both potency and contaminants. Ensure that the supplements are manufactured in FDA-approved facilities and bear the Good Manufacturing Practice (GMP) stamp. These indicators guarantee that the product meets stringent quality standards and is free from impurities, assuring you of a reliable and high-quality supplement.

  • Dose and Potency

Examine the dosage and potency of the supplement carefully. For vitamin D3, adhere to the recommended dosage by the Food and Nutrition Board (FNB), typically ranging between 1000 and 5000 IU (25-125mcg) daily. In specific situations where a rapid response to deficiency is needed, a higher but not exceeding 10000 IU (250mcg) may be considered. As for vitamin K2, the optimal daily dose varies, but it is commonly recommended within the range of 45-180 mcg. 

  • Form

Take into account the form of the supplement. Vitamin D3 and K2 supplements are available in capsules, soft gels, gummies, and liquid forms. Liquid supplements have faster absorption, making them suitable for those with swallowing difficulties. Capsules and soft gels are appropriate for individuals comfortable with swallowing, while gummies are a preferred choice for those who enjoy chewing. 

  • Additional Ingredients

Pay attention to additional ingredients used in the supplement. Some K2 or D3 supplements incorporate extra ingredients like soybean oil, corn oil, Ox Bile, Other Vitamins, magnesium, or zinc for added health benefits. Ensure these additional ingredients do not hinder vitamin absorption. Avoid supplements with fillers, preservatives, or artificial additives, and opt for products with clean, natural ingredients. 

Things to Avoid When Choosing Vitamin D3 and K2 Supplement?

When selecting the best D3 K2 supplement, there are a few things to avoid. First, avoid supplements that contain unnecessary fillers, additives, or artificial ingredients. These can potentially diminish the effectiveness of the supplement or cause unwanted side effects. Second, beware of supplements lacking third-party testing or transparent ingredient sourcing. Lastly, avoid misleading marketing claims and opt for reputable brands with a history of quality assurance.

Who Should Take Vitamin D3 and K2 Supplements?

Vitamin D3 and K2 supplements are beneficial for various individuals. Those who have limited sun exposure, such as office workers or individuals living in colder climates, may require supplementation to meet their vitamin D supplement needs. 

Additionally, individuals with darker skin tones, older adults, and individuals with conditions affecting fat absorption or calcium metabolism may also benefit from vitamin D3 and K2 supplements. Furthermore, those who follow a vegan or vegetarian diet may have a higher risk of deficiency and can benefit from supplementation. 

How We Chose the Best D3 and K2 Vitamin Supplements?

Rigorous quality control measures, third-party testing, and adherence to industry standards were pivotal criteria in our selection process. All our recommendations tick these boxes.

Transparency in manufacturing and ingredient sourcing is paramount.

Clear and detailed labeling, including the origin of ingredients, allows consumers to make informed decisions about the supplements they choose.

  1. Best Ingredients:

All our picks not only adhere to the recommended dosage by the FNB (Food and Nutrition Board) but also ensure their products pass third-party and lab testing.

Potential Side Effects Of Taking Vitamin D3 and K2

While vitamin D3 and K2 are generally safe when taken in recommended doses, excessive supplementation can lead to side effects. The Food and Nutrition Board (FNB) places excessive supplementation at daily intakes above 250 mcg of Vit. D3 and 145 mcg of Vit. K2.

High doses of vitamin D3 can cause symptoms such as nausea, vomiting, constipation, fatigue, and weakness. It can also lead to elevated calcium levels in the blood, which may result in kidney stones, heart health problems, and damage to other organs. Excessive vitamin K2 intake may interfere with blood-thinning medications and increase the risk of blood clotting. 

How Does Vitamin D3 And K2 Supplements Work Together?

Vitamin D3 and K2 supplements work together synergistically to support various body processes, including the crucial role of helping the body absorb calcium. Vitamin D3 helps in the absorption of calcium and phosphorus, supporting bone health. 

Meanwhile, vitamin K2 activates proteins responsible for directing calcium into the bones and teeth, preventing it from accumulating in soft tissues and blood vessels. In combination, these vitamins help optimize bone health, cardiovascular health, and overall well-being.

What Are The Best Food Sources Of Vitamin D?

The best food sources of vitamin D supplements are:

1. Fatty Fish: Certain types of fish, such as salmon, mackerel, and sardines, are high in vitamin D. Canned tuna and trout can also be good sources.

2. Cod Liver Oil: This oil, derived from the liver of fish, is rich in vitamin D. It is available as a supplement in liquid or capsule form.

3. Mushrooms: Some types of mushrooms, like shiitake and maitake mushrooms, contain small amounts of vitamin D. The vitamin D content is higher when mushrooms are exposed to ultraviolet (UV) light.

4. Egg Yolks: Egg yolks contain a small amount of vitamin D. However, it is important to note that most of the vitamin D in eggs is found in the yolk, so consuming the whole egg is necessary to reap the benefits.

6. Beef Liver: While not commonly consumed in high amounts, beef liver is a good source of vitamin D.

FAQs About Vitamin D3 And K2 Supplements

Q1. Who should not use vitamin D3 and K2 supplements?

While Vitamin D3 and K2 supplements are generally safe for most individuals, certain groups should exercise caution or avoid them altogether. These include individuals with hypercalcemia or hyperparathyroidism, those with certain kidney or liver conditions, and individuals taking certain medications like digoxin or thiazide diuretics. 

Q2. How long do vitamin D3 and K2 supplements take to work?

The time it takes for Vitamin D3 and K2 supplements to work can vary depending on individual factors such as current deficiency levels, overall health, and dosage. Typically, it can take several weeks to months to see noticeable effects. Regular and consistent supplementation, along with a balanced diet and lifestyle, is essential for optimal results. 

Q3. What is the preferred time to take K2 and D3 supplements?

For optimal absorption, it is recommended to take Vitamin D3 and K2 together, ideally during breakfast or lunch, as these are times when the body synthesizes Vitamin D from sunlight. While there is no scientific evidence supporting the notion that taking this supplement at night causes insomnia, it is advisable to avoid doing so for better precaution.

Q4. Are vitamin D3 and K2 supplements beneficial for sleep?

The impact of vitamin D3 and K2 supplements on sleep remains inconclusive, with some studies suggesting an improvement in both quality and quantity, while others assert no effect or even a potential decrease in sleep quality. The variance in findings may be attributed to differences in the duration of the studies,

Q5. Do you get enough vitamin D from the sun?

Getting enough vitamin D from the sun is pretty natural. Try to spend about 10–30 minutes in the sunlight during midday a few times a week to keep your blood levels healthy. If you have darker skin, you might need a bit more sun time. Just pay attention to how your skin reacts to sunlight and adjust accordingly.

Q6. What are the differences between vitamin D3 and K2 supplements?

Vitamin D3 and K2 supplements play different yet complementary roles in supporting overall health. Vitamin D3 primarily helps the body absorb calcium from the intestines, crucial for maintaining strong bones and supporting immune function. On the other hand, vitamin K2 is essential for preventing the accumulation of calcium in arteries and soft tissues, hence supporting overall cardiovascular health. 

Concluding Thoughts: What is The Best Brand For Vitamin D3 and K2?

In conclusion, the best vitamin D3 and K2 supplements in 2024 offer a convenient and effective way to support our overall health. These supplements provide the essential nutrients needed for strong bones, calcium absorption, and cardiovascular health.
