L-Carnitine Dietary Supplements Investigation

Tycko & Zavareei LLP is currently investigating dietary supplements that contain the amino acid L-carnitine.  Dietary supplement manufacturers have made various representations regarding the health-related benefits associated with taking L-carnitine, such as improved heart health and metabolism.

Our firm is investigating whether there exists a scientific or otherwise legitimate basis for these claims.  Although we have not yet reached any final determinations, our initial analysis indicates that some or all of the health claims made about L-carnitine supplements are inflated, or lack a valid scientific basis.  Experts in cardiovascular medicine question whether the average consumer would derive any health benefit from taking L-carnitine supplements.  And a recent study by the Cleveland Clinic concluded that increased levels of carnitine may lead to heart disease.  Accordingly, we believe that consumers may be misled into paying for these supplements and potentially even putting themselves at risk.

Our investigation is particularly focused on the following two brands of L-carnitine supplements:

  • Nature’s Bounty
  • Spring Valley

If you, or someone you know, has purchased either of these products, or other products containing L-carnitine, please fill out the contact form on our website and someone from our firm will contact you shortly about your experience.  In the alternative you may call our firm directly at (202) 973-0900.
