Sports Research Vitamin K2 Citrus Aroma Bone & Heart Health 60 Softgels

SKU: 104394

Sports Research Vitamin K2 provides MK-7 (menaquinone-7) — the longer-half-life form of vitamin K2 — in a coconut MCT oil base with light citrus aroma for palatability. K2 directs calcium toward bones and teeth and away from arteries, supporting both skeletal and cardiovascular wellness. Particularly important when supplementing high-dose vitamin D3, since D3 increases calcium absorption while K2 ensures it routes correctly. The 60-softgel bottle is a 2-month supply. Critical: people on warfarin must consult their prescriber before any K2 supplementation — K2 reduces warfarin effectiveness and requires dose adjustment plus INR monitoring.

    A: MK-7 (menaquinone-7) has a much longer half-life in the body (about 72 hours) compared to MK-4 (about 1 to 2 hours). This means MK-7 maintains steady blood levels with once-daily dosing, while MK-4 requires multiple daily doses for similar effects. Most modern K2 research uses MK-7, and most quality K2 supplements provide MK-7. Some products use MK-4 at higher doses — both forms work for bone and arterial health when properly dosed, but MK-7 is more convenient and has stronger newer evidence.

    A: K2 is most relevant for: people taking high-dose vitamin D3 (1000+ IU daily), older adults concerned about bone density and arterial calcification, those with limited dietary K2 (Western diets generally low — K2 is in natto, aged cheeses, grass-fed animal products), and people with osteoporosis or cardiovascular concerns. Healthy adults eating fermented foods and grass-fed dairy may not need supplemental K2. Get a complete picture from your healthcare provider rather than universal recommendations.

    A: Pure vitamin K2 in MCT oil can have a slightly off taste or smell to some users. The light natural citrus aroma improves palatability without affecting the active ingredient or its effectiveness. Citrus aromatic compounds in the small amounts used are not bioactive at supplement levels — purely a sensory enhancement. The softgel still delivers the same MK-7 dose as comparable unflavored products.
