Conjugated Linoleic Acid (cla) and Tinzaparin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Tinzaparin

Tinzaparin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Conjugated Linoleic Acid (cla) interacts with.

Theoretically, CLA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Some clinical evidence suggests that intake of CLA reduces platelet aggregation by approximately 10%. The clinical significance of this effect is unclear.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Tinzaparin (Innohep) is a blood thinner, a low molecular weight heparin you inject under the skin. It works by slowing your blood's ability to form clots. CLA isn't broken down by the same pathways, so this isn't an enzyme issue. Instead, some early research hints that CLA may make platelets (the cells that help blood clot) a little less sticky, by around 10%.

Put those together and, in theory, you could bleed a bit more easily: think easy bruising, nosebleeds, bleeding gums, or longer bleeding from small cuts. Keep in mind this is theoretical and based on pharmacology, not strong human studies. Still, since tinzaparin already thins your blood, please check with your pharmacist or doctor before adding a CLA supplement.

About Conjugated Linoleic Acid (cla)

What is Conjugated Linoleic Acid (cla)?

Conjugated Linoleic Acid (cla)
  • Weight loss
  • Improving body composition
  • Sports and muscle support
  • Reducing inflammation
  • General wellness

CLA is a fatty acid found naturally in meat and dairy, and supplements are usually made from safflower oil. While it is popular for fat loss and body composition, research results are mixed and any real-world effect appears small at best. It is likely safe for short-term use in most healthy adults, but talk to your pharmacist or doctor before starting it.
