What it does
Are forms of vitamin K2, a family involved in activation of vitamin K-dependent proteins.
Possible deficiency symptoms
There is no separate symptom checklist that diagnoses an MK-4 or MK-7 deficiency.
How supplementation is approached
MK-4 and MK-7 are forms of vitamin K2. Dr. Purser discusses vitamin K with bone and vitamin D support, but the exact form and existing combined products matter. Anticoagulant use must be reviewed before adding or changing vitamin K.
Food sources
Some cheeses and fermented foods; natto is a source of MK-7.
Supplement forms
Menaquinone-4 (MK-4) and menaquinone-7 (MK-7), often paired with vitamin D. Verify the individual amounts.
What to track and reassess
If taking warfarin, coordinate vitamin K intake with the anticoagulation team and continue their monitoring plan. Do not use a genetic result to decide that an anticoagulant is ineffective.
From starting support to follow-up
If you and your clinician start a CMA replenishment plan, you may add one new product at a time, often waiting 3–7 days to see how you feel. A check-in is usually planned near ten weeks during an approximately 100-day period. Follow your written plan for amounts and timing. At follow-up, you may continue, change, or stop each item. This timetable does not automatically end longer-term support.
