Rhonda Patrick on Vitamin K2
5 episodes · 9 references · 2015–2025
- Patrick takes 50 mcg/day of vitamin K2 (MK-7) and considers it important for cardiovascular and bone health - Emphasizes K2's role in activating proteins that remove calcium from arteries and direct it to bones - No cautions, risks, or reasons to avoid K2 discussed across her references
Consumption
- Takes MK-7 (menaquinone-7) specifically, chosen for its longer half-life over MK-4 - Doses at 50 mcg/day, which she believes is likely more than sufficient - Takes K2 in the evening as part of her daily supplement routine
Benefits
- 25-50 mcg/day of K2 shown to decrease calcium buildup in arteries - Activates proteins that pull calcium out of blood vessels and arteries, directing it to bones - K vitamins activate proteins essential for coagulation, vascular calcium removal, and bone homeostasis
Best Practices
- Vitamin K1 is low in breast milk; AAP recommends K1 injection for all newborns to prevent hemorrhaging - No specific K2 timing or food-pairing guidance beyond evening dosing - No discussion of upper limits or interactions with other supplements
“I personally take MK-7, which is menaquinone-7, which has a longer half-life than MK-4. I take 50 micrograms a day.”

“In the evening, I take my K2.”
Rhonda Patrick's EXACT Supplement Routine (doses, timing, & brands revealed)
“I personally do take vitamin K2 and I take around 50 micrograms a day. I even think that's probably more than enough.”
Rhonda Patrick at Orthomolecular Medicine Congress in Bussum, Netherlands (Keynote Oct. 3rd, 2015)
“There have been some studies showing that taking between 25 and 50 micrograms a day of vitamin K2 does decrease calcium buildup in the arteries.”
Rhonda Patrick at Orthomolecular Medicine Congress in Bussum, Netherlands (Keynote Oct. 3rd, 2015)
“Vitamin K is also required to activate proteins that pull calcium out of the vascular system, out of the blood vessels and arteries, and bring it to the bone where it's supposed to go.”
Rhonda Patrick at Orthomolecular Medicine Congress in Bussum, Netherlands (Keynote Oct. 3rd, 2015)
“Vitamin K2 is important for pulling calcium out of the bloodstream to prevent calcification of the arteries and take it to the bones.”
Bruce Ames on Triage Theory, Longevity Vitamins & Micronutrients
“Both vitamin k1 and vitamin k2 are required as cofactors to activate proteins in the body that serve three important functions: coagulation, removing calcium out of the bloodstream, and maintaining bone homeostasis.”
Rhonda's Ultimate Micronutrient Smoothie
“Vitamin K serves a very important function for short-term survival in that it activates proteins that are required for coagulation and blood clotting.”
Rhonda Patrick at Orthomolecular Medicine Congress in Bussum, Netherlands (Keynote Oct. 3rd, 2015)
“Vitamin K1 is very low in breast milk, so the American Academy of Pediatrics recommends that all newborn infants receive an injection of vitamin K1 to prevent hemorrhaging shortly after birth.”
