If you’re on the health-conscious side, you may have a few supplements in your rotation. After all, supplements often present a possible solution to a number of health issues—whether you’re experiencing poor sleep, a lack of focus, or an unbalanced gut microbiome. However, while they can certainly help improve your wellbeing, it’s crucial to be mindful of the potential risks at hand. You know what they say: too much of a good thing can be a bad thing, and this is especially true when it comes to certain supplements. In fact, there are a few common choices that could pose a serious risk to your liver health when consumed in large doses.

To shed some light on some supplements you should be cautious with for the sake of your liver, we spoke to Lisa Andrews MEd, RD, LD, a registered dietitian nutritionist, and Dr. Rimas Geiga. They warned against high doses of Garcinia Cambogia and Green Tea Extract. Learn more about the risk of each below.

1. Green Tea Extract

Green tea is a fantastic elixir with a range of health benefits. In supplement form, green tea extract is well known for its antioxidant properties, primarily due to its high concentrations of catechins like epigallocatechin gallate (EGCG).

However, Dr. Geiga warns that, while there are many benefits to green tea, "high concentrations of catechins in green tea extract can induce oxidative stress in the liver, leading to hepatotoxicity." This oxidative stress may manifest as elevated liver enzymes and, in severe cases, acute hepatitis.

To mitigate these risks, it's best to limit your intake to no more than 300 mg per day. Or better yet, brew up some green tea as a safer (tasty) alternative!

2. Garcinia Cambogia

Derived from a tropical fruit, Garcinia Cambogia is often praised for its weight loss benefits. However, Andrews cautions that its use may come with a range of unpleasant side effects—and even some dangerous downsides for your health.

"Side effects from its use may include headache, nausea, diarrhea, and other gastrointestinal concerns," she explains. More alarmingly, in some cases, Garcinia Cambogia has been linked to liver damage, further emphasizing the potential dangers associated with its consumption. Yikes! There are several other supplements to avoid for your liver health, too.

Bottom Line

In most cases, the supplements you'll find on health store shelves are perfectly safe. But as with anything else you're putting into your body, it's vital to stay aware of any risks at hand—especially if you're concerned about your liver health. When it comes to supplementation, it's always a good idea to speak to your doctor about your personal needs, goals, and risk factors. Stick to recommended dosages, monitor any side effects, and reach out to a healthcare provider if issues arise. Stay safe!
