Hi, I have Reumatoid arthritis and take Methotrexate which lowers my immune system and I have underactive thyroid (take thyroxine) I cant take anything that boosts my immune system so the question is does anyone else take Collagen which doesnt boost your immune system as I know there are a lot of different ones you can get.
From what I understand, plain collagen is not usually classed as an immune booster. I’d just be careful to choose a simple one without added ‘immune support’ ingredients, and check with your pharmacist or GP first because methotrexate can interact with supplements generally. Also watch for added calcium, iron, soya or kelp, as those can affect how thyroxine works
