A 100mcg dose of vitamin k2 should be sufficient for general supplementation in the average person. The upper safe level for long term use of vitamin K supplements is 1000mcg (1mg) - which would be 10 capsules per day. If you have a specific requirement for a higher dose or have been advised to take on by a medical practitioner then you could take up to 10 capsules per day safely.
