Quick answer

To choose a vitamin K2 supplement for bone health, focus on the MK-7 form (menaquinone-7), a consistent daily dose of 100 mcg, and a reputable brand like Sports Research.

Why MK-7 matters for bone health

Vitamin K2 comes in two main forms: MK-4 and MK-7. MK-7 stays active in your body longer, making it more effective for directing calcium to bones and away from arteries. This sustained activity supports bone mineralization over a full day.

When shopping, check the label for MK-7 (menaquinone-7). Many bone health supplements use MK-4, which requires multiple doses daily to maintain levels. MK-7 offers convenience with once-daily dosing.

Dosage: 100 mcg as a practical starting point

Research suggests that 100 mcg of MK-7 per day is a common and effective dose for bone support. This amount aligns with many clinical studies and is easy to find in supplements like Sports Research 100 MCG softgels.

Higher doses (180 mcg or more) may be appropriate for specific needs, but 100 mcg works well for general bone health maintenance. Always consult a healthcare professional before changing your supplement routine.

Steps to choose your vitamin K2 supplement

Check the form: MK-7: Look for MK-7 (menaquinone-7) on the label. MK-7 stays active longer and supports bone health with once-daily dosing. Avoid supplements that only list MK-4 unless you plan multiple doses. MK-7 is the preferred form for bone health due to its longer half-life.
Verify the dose: 100 mcg daily: Choose a supplement that provides 100 mcg per serving. This is a well-studied amount for bone support. If you have specific needs, consult a professional for a tailored dose. 100 mcg is a practical starting point; adjust only with professional guidance.
Select a trusted brand: Opt for a brand with transparent labeling and quality sourcing. Sports Research offers a 100 MCG / 60 Softgels option with a clear dose and softgel format for easy absorption. A trusted brand ensures you get what is on the label.
