Compare mechanism, clinical dose, safety profile, and products containing each ingredient.
Overview
Vitamin K2 is usually chosen for Those taking D3, seeking bone/cardiovascular health, while Calcium is often selected for Those with low dairy intake, postmenopausal women.
Directs calcium to bones, away from arteries. Synergizes with D3 for bone health.
Clinical dose: 100-200 mcg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Essential for bone health, muscle contraction, nerve signaling.
Clinical dose: 500-1000 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Vitamin K2
Vitamin K2 acts through dose-dependent biochemical pathways that influence energy metabolism, neurotransmission, or tissue function. Clinical outcomes vary with ingredient form, dosing consistency, and total stack composition in the product.
Calcium
Marketing claims: "Strong bones," "Prevents osteoporosis." Reality: Calcium works best from food and when combined with vitamin D and weight-bearing exercise. High-dose supplements alone may increase cardiovascular risk. Most Indians get adequate calcium from dairy — supplementation is mainly for those avoiding dairy or with diagnosed deficiency.
