Hawthorn berry supplements have been associated with an increased risk of bleeding, particularly in surgical settings¹. This is something to be aware of if you are considering taking hawthorn berry supplements, especially if you are taking any medications that affect blood clotting.

Vitamin K2, on the other hand, is known for its role in blood clotting. It helps to maintain normal blood coagulation by assisting in the regulation of calcium in the blood and preventing its deposition in the blood vessels¹.

Combining these two supplements should generally be safe for most people because they have different roles and effects on the body. However, if you have any pre-existing health conditions, are taking blood-thinning medications, or are planning to undergo surgery, it's recommended to consult with a healthcare professional before starting these supplements. This is because of the potential for hawthorn to affect bleeding tendencies, which could interact with medications or health conditions related to blood clotting¹.
