After exploring some of the most popular vitamin D3 and K2 combinations on the market, we found Meo Nutrition’s D3 + K2 formula to be a standout choice.

This supplement provides an optimal dosage for maintaining healthy vitamin D and K levels, delivering 5,000 IU of vitamin D3 and 100 mcg of vitamin K2. These amounts are designed not only to address severe deficiencies but also to support those with milder needs, ensuring a broad range of individuals can benefit.

Meo Nutrition goes even further by enhancing bioavailability. The inclusion of BioPerine®—a patented black pepper extract—helps your body absorb these nutrients more efficiently. Plus, the formula supplies additional calcium to further support bone health, making it a well-rounded choice for overall wellness.

Transparency is a core value at Meo Nutrition, reflected in their clear and honest ingredient labeling. You’ll know exactly what’s in each capsule.

Orders also arrive promptly, and the product is competitively priced. With a subscription, the cost can drop down to $24.99 per bottle.

Moreover, customer reviews frequently highlight both the easy-to-swallow capsules and the noticeable improvements they experience.

Last but not least, all Meo Nutrition supplements are manufactured in Utah, US within GMP-certified and NSF Sport-approved facilities. This, along with their UDAF Organic Certification, ensures each bottle meets rigorous standards of quality and purity.

The Sports Research D3 + K2 supplement provides 125 mcg (5000 IU) of vegan Vitamin D3 (cholecalciferol) sourced from lichen and 100 mcg of Vitamin K2 (as MK7) derived from fermented chickpeas. This combination ensures efficient calcium absorption and proper calcium distribution to bones rather than arteries or joints.

Moreover, they use plant-based tapioca gelatin in the soft gels, so they don't contain any bovine, porcine, or carrageenan.

The addition of coconut MCT oil enhances nutrient absorption, making it a potent, plant-based formula.

Given Sports Research's dedication to clean, effective supplements and third-party quality testing, this product deserves one of the top spots in our review.

Overall, if you're looking for a 100% plant-based D3 + K2 supplement that supports bone and immune health, and the price is not a concern, Sports Research D3 + K2 is an exceptional choice.

Micro Ingredients’ Double Strength 2-in-1 Vitamin D3 + K2 softgels offer a potent formula, combining 10,000 IU of Vitamin D3 (cholecalciferol) with 200 mcg of Vitamin K2 (MK7), additionally infused with MCT coconut.

One notable feature is the bulk packaging: each pouch contains 300 mini softgels, offering a 10-month supply. While this may be cost-effective for some, the large quantity may be inconvenient for those who prefer smaller, shorter-term purchases or want to test the product before committing to a long-term supply.

Another concern is the high potency of each dose. With double the upper recommended daily intake of Vitamin D3, consistent use may increase the risk of hypervitaminosis D, potentially leading to elevated blood calcium levels, muscle spasms, or other complications.

It’s crucial to monitor your intake or consult a healthcare professional before long-term use, especially if you're already supplementing with other sources of Vitamin D.

NUSAVA’s Organic Vitamin D3 + K2 Drops with MCT Oil and Omega-3 offer a potent 4-in-1 liquid supplement designed for maximum absorption and convenience. Each serving contains 125 mcg (5000 IU) of Vitamin D3, 120 mcg of Vitamin K2, 250 mg of Omega-3, and a blend of organic ingredients.

The liquid form is an excellent option for those who have difficulty swallowing pills. The inclusion of MCT oil helps enhance the bioavailability of these fat-soluble vitamins, ensuring optimal nutrient uptake.

NUSAVA’s formula is certified organic, non-GMO, and made in the USA, with no fillers or unwanted additives. Additionally, the company offers a hassle-free refund or replacement policy, giving users confidence in their purchase.

However, while the liquid format is advantageous for many, some people may find the taste or texture of liquid supplements unappealing. Additionally, precise dosing can sometimes be tricky compared to pre-measured capsules.

Bronson Vitamin K2 (MK7) with D3 offers an affordable and straightforward approach to vitamin D supplementation.

Bronson’s formula is non-GMO, gluten-free, and soy-free, and it is tested in their in-house facility in New York. With a legacy of quality dating back to 1960, Bronson has earned trust from consumers and medical professionals alike.

The supplement’s standout feature is its affordability, priced at under $10 per bottle, making it accessible for many.

However, the product does have some limitations. It lacks third-party testing, which may be a concern for those who value independent verification of quality and purity.

Additionally, the formula does not include absorption enhancers like Bioperine or MCT oil, which could improve the bioavailability of these fat-soluble vitamins.
