Life Extension Super K is a bone and heart health support supplement that helps keep bone density and healthy arteries, because of a mix of vitamins K1, K2 and vitamin C [designed for steady daily support]. The key actives are K1, MK-4 and MK-7, designed for steady daily support.

Available Sizes & Variants:

90 softgels — standard bottle for daily use with meals.

Benefits & Features:

• Supports bone health by activating osteocalcin for mineralisation, and enabling everyday mobility.
• MK-7 offers longer bioavailability for sustained daily benefits, meaning your bones and arteries can benefit across the day rather than in short bursts, supporting mobility and heart health during daily activities.
• Activates matrix Gla protein to help protect arteries from calcification and stiffness, which helps keep things flexible.
• Designed to be taken with food as a softgel containing extra virgin olive oil, which aids absorption and makes daily dosing simple for busy mornings.
• Non-GMO formula for a cleaner label, plus everyday peace of mind.
