- Carvalho does not take K2 and does not recommend it for heart health, finding insufficient evidence for personal use - Acknowledges K2 may benefit bone density in postmenopausal women with osteoporosis, but considers this a narrow population - No dosing guidance or personal consumption discussed; stance is skeptical despite K2's popularity as a vitamin D companion
Benefits
- Vitamin K plays a fundamental role in coagulation - K2 probably helps increase bone density in postmenopausal women with osteoporosis - Some evidence suggests K2 supplementation may lower fracture risk in postmenopausal populations
