Creatine Kinase

I have just had a Bloods test result and told have increasing rapidly Creatine Kinase levels.(I have OA). I am a walker now only Dog about 1 hour total Urban area and of thin build naturally. In last 4 weeks for first time i have taken Vit D3 + K2 combined 100yg/100yg but added 2 weeks ago Antartic Krill Oil soft gels later twice a day maybe causing high Creatine Kinase not seeing GP about this till 29 April so am stopping both for now till then.My question to Community is have you had similar issues and does OA typically cause high Creatine Kinase levels and will ask GP first does one normally take Kinase supplement to control Kinase ? Read Internet and NHS up thoroughly confusing. Thanks GP i will strictly follow as my medical guide.
