Does hydrolyzed marine collagen interact with any medication?Updated a month ago

Marine collagen is not known to interact with any medications, and there are no contraindications listed in the Health Canada monograph for hydrolyzed collagen.

People often ask about interactions with the following types of medications:

• Thyroid medications – no known interactions. Collagen is a protein, and like any protein, it does not interfere with thyroid hormone function. Additionally, Landish marine collagen does not contain iodine, so it will not affect thyroid function or medication. However, thyroid medication (e.g., levothyroxine) should always be taken on an empty stomach for optimal absorption.
  

• Blood thinners and anticoagulants – no known interactions with medications like warfarin, aspirin, or clopidogrel.
  

• Diabetes medications – no known interactions with insulin, metformin, or other diabetes drugs.
  

• Blood pressure medications – no known interactions with beta-blockers, ACE inhibitors, or other antihypertensives.
  

• Anti-inflammatory drugs (NSAIDs & corticosteroids) – no known interactions with ibuprofen, prednisone, or similar medications.
  

• Osteoporosis medications – no known interactions with bisphosphonates like alendronate or risedronate.
  

• Digestive and acid reflux medications – no known interactions with proton pump inhibitors (PPIs) or antacids.

Collagen is simply a source of bioavailable protein that provides key amino acids to support tissue health. It does not interfere with drug metabolism or absorption.

If you have specific concerns, a healthcare professional can provide guidance, but based on existing research and regulatory approval, collagen is considered safe to take alongside medications.

This guidance applies specifically to our Pure Canadian Marine Collagen.

Our Marine Collagen Sparkling Waters contain only 45 mg of vitamin C as an additional active ingredient, which is considered perfectly safe with medication.

Our Beauty Blend, Coffee Creamer, Marine Collagen Gummies, contain additional ingredients that may interact with medications.
