The VITBOOST Vitamin D3 K2 Complex is a high-potency supplement designed for adults who want to boost their immune system and support bone health. With 5000 IU of Vitamin D3 and 90 mcg of Vitamin K2 (as MK-7), this formula ensures that both vitamins work together for optimal absorption and effectiveness.
What sets this supplement apart is its use of the MK-7 form of Vitamin K2, which is known for its superior bioavailability compared to MK-4. This means your body can more easily utilize the nutrients, leading to better support for calcium metabolism and arterial health. The product is also non-GMO, gluten-free, and sugar-free, making it suitable for a variety of dietary needs.
The bottle contains 120 softgels, providing a convenient four-month supply. Each softgel is manufactured in a cGMP certified facility in the USA and undergoes third-party testing to ensure purity and potency. The ingredients are free from artificial fillers, preservatives, and common allergens, which adds to its appeal for health-conscious consumers.
A potential drawback is the lack of verified customer reviews, as this is a relatively new listing. Additionally, because these are fat-soluble vitamins, taking them with a meal containing healthy fats can enhance absorption.

Pros
- Dual nutrient formula for comprehensive bone and heart support
- Trusted brand with a reputation for quality and purity

Nature Made Vitamin D3 K2 Supplement is a dietary supplement designed for adults who want to support their bone and heart health. It combines two essential nutrients: Vitamin D3, which helps the body absorb calcium, and Vitamin K2, which directs calcium to the bones and teeth, preventing it from depositing in arteries. This makes it an excellent choice for those looking to maintain strong bones and a healthy cardiovascular system.
The standout feature of this product is its dual-action formula. Vitamin D3 is well-known for its role in calcium absorption, but without Vitamin K2, calcium can accumulate in soft tissues like arteries. By including both, Nature Made ensures that the calcium you consume goes where it is needed most, providing comprehensive support for bone density and heart health.
In terms of design and build quality, the softgels are easy to swallow and free from artificial colors and preservatives, aligning with Nature Made's commitment to purity. The packaging is practical, with a 30-count bottle that is convenient for daily use. However, as with any supplement, results may vary, and it is important to use it consistently as part of a healthy lifestyle.
One potential drawback is the lack of customer reviews at this time, which means there is no real-world feedback to gauge effectiveness. Additionally, individuals taking blood thinners or those with vitamin K deficiencies should consult a healthcare professional before use, as vitamin K can interact with certain medications.
Overall, Nature Made Vitamin D3 K2 Supplement is a solid choice for anyone seeking a high-quality, dual-nutrient supplement to support bone and heart health. Its trusted brand reputation and clean formulation make it a reliable addition to your daily wellness routine.

Buying Guide: How to Choose the Best Vitamin D3 and K2 for Men
Dosage and Ratio of D3 to K2
Vitamin D3 dosages typically range from 1,000 to 5,000 IU per serving. For men, 5,000 IU is common for maintaining optimal levels, especially if you have limited sun exposure. Vitamin K2 (as MK-7) is often paired at 90 to 100 mcg. The right ratio ensures that calcium is properly utilized. Look for supplements that clearly state both amounts on the label.
Form and Absorption
Vitamin D3 is fat-soluble, so taking it with a meal containing healthy fats improves absorption. Some supplements include coconut oil or other oils in softgel form. For those following a plant-based diet, vegan D3 from lichen is available. Capsules, softgels, and liquid drops are common forms. Choose one that fits your lifestyle.
Quality and Purity
Third-party certification and non-GMO, gluten-free, and allergen-free labels add confidence. Brands that manufacture in cGMP facilities in the USA often adhere to stricter standards. Our reviewed products all meet high purity criteria. For more insights on men’s vitamin quality, visit our Men’s Vitamins category page.
Specific Needs: Vegan or Extra Support
If you require a vegan supplement, choose a brand like Sports Research that uses plant-derived D3. For those seeking added bone or immune support, some formulas include additional nutrients like magnesium. Learn about how magnesium complements D3 in our article on magnesium glycinate benefits for men.
Final Thoughts
After careful review, we recommend VITBOOST Vitamin D3 K2 Complex – 5000 IU (125 mcg) for men who want a high-potency, affordable option with enhanced absorption, and Sports Research® Vegan Vitamin D3 + K2 w/Coconut for those seeking a plant-based, premium formula with coconut oil for better uptake. Both deliver the synergistic benefits of D3 and K2 to support your bone density and immune function.
Frequently Asked Questions
Why do men need vitamin D3 and K2 together?
Vitamin D3 helps your body absorb calcium, while vitamin K2 directs that calcium to your bones and teeth rather than allowing it to build up in arteries. This combination is especially important for men over 40 to maintain bone density and heart health.
What is the best time of day to take vitamin D3 and K2?
Take them with a meal that contains fat, such as breakfast or lunch, to maximize absorption. Consistency is key. Some men prefer morning intake to avoid potential sleep interference, though D3 is not typically stimulating.
Can I take vitamin D3 and K2 with other supplements?
Yes, but be mindful of total vitamin D intake if you are also taking a multivitamin or separate D3. Vitamin K2 has no known upper limit, but always consult your healthcare provider. For a deeper look at men’s supplement stacks, see our best D3 for Men’s health guide.
Are there any side effects of vitamin D3 and K2 for men?
At recommended dosages, side effects are rare. Excessive vitamin D3 can cause calcium buildup, but the presence of K2 helps mitigate that risk. Always stick to the serving size on the label and discuss with your doctor if you have any medical conditions.
