Vitamin E and Vitamin K1: Can You Take Them Together?

Häufig gestellte Fragen

Kann man Vitamin E und Vitamin K1 zusammen einnehmen?

Vitamin E und Vitamin K1 können wechselwirken. Vitamin E at supplement doses measurably lowered vitamin K status in adults with normal clotting, and vitamin E-induced coagulopathy has been reported at high intakes. Someone taking vitamin K for bone or vascular reasons is partly undoing it with high-dose vitamin E. Keep vitamin E at or below 400 IU/day if you are also taking vitamin K, and separate them by a few hours to reduce absorption competition. Do not use this pairing to self-manage clotting: if you are on an anticoagulant, both belong in a conversation with the prescriber.

Wechselwirken Vitamin E und Vitamin K1?

Vitamin E at supplement doses measurably lowered vitamin K status in adults with normal clotting, and vitamin E-induced coagulopathy has been reported at high intakes. Someone taking vitamin K for bone or vascular reasons is partly undoing it with high-dose vitamin E. High-dose alpha-tocopherol interferes with vitamin K-dependent gamma-carboxylation, and its quinone metabolite competes with vitamin K in that pathway. The two are also fat-soluble vitamins competing for the same absorption route.
