Micro Ingredients Vitamin D3 K2 MK-7 is a high-potency supplement designed for adults who want robust bone and immune support. Each serving delivers 10,000 IU of vitamin D3 and 200 mcg of vitamin K2 in its most bioavailable MK-7 form, all in a single daily softgel.

The standout feature is the inclusion of MCT coconut oil as a carrier, which significantly improves the absorption of these fat-soluble vitamins. Real-world performance is expected to be excellent given the quality of ingredients and third-party testing, though no customer reviews are available yet. The double-strength dose means you get more benefit per capsule, reducing the number of pills you need to take.

Buying Guide: How to Choose the Best Vitamin D3 K2 for Men
Not all D3 K2 supplements are created equal. Here are four key factors to consider when selecting the right product for your needs.
1. Dosage Strength: D3 and K2 Amounts
Vitamin D3 dosages range from 1,000 IU to 10,000 IU per serving. For men who spend limited time in the sun or have darker skin, higher doses (5,000 to 10,000 IU) may be beneficial. Vitamin K2 is typically dosed at 100 to 200 mcg. The Micro Ingredients option delivers a potent 10,000 IU D3 plus 200 mcg K2, while Sports Research offers a moderate 2,500 IU D3 with 100 mcg K2. Choose based on your baseline levels and health goals. If you’re also taking other supplements, check for cumulative vitamin D intake.
2. Form of Vitamin K2: MK-7 vs. MK-4
Vitamin K2 comes in two main forms: menaquinone-4 (MK-4) and menaquinone-7 (MK-7). MK-7 is derived from natto (fermented soy) and stays active in the body longer, making it the preferred form for once-daily dosing. All five products in our list use the MK-7 form, which is ideal for sustained support of arterial health and calcium metabolism. For more on how magnesium complements this duo, see our guide to magnesium for cardiovascular support.
3. Absorption: Fat-Soluble Delivery
Both D3 and K2 are fat-soluble vitamins, meaning they absorb best when taken with dietary fat. Many supplements include a carrier oil like coconut or MCT oil to improve bioavailability. Micro Ingredients and Sports Research specifically mention coconut oil in their formulas. If you prefer a vegan option, Sports Research uses organic coconut MCT oil in their plant-based softgels. For men with digestive issues, choosing a product with built-in fat can make a real difference.
4. Purity and Dietary Preferences
Look for supplements that are third-party verified for purity and potency. Avoid artificial additives, gluten, soy, and GMOs if you have sensitivities. Pure Encapsulations is known for its hypoallergenic formulations, while Nutricost offers a budget-friendly non-GMO option. If you follow a vegan diet, the Sports Research Vegan D3 + K2 is certified vegan and Non-GMO Project Verified. Always check the label for allergens.
