Best Milk Thistle Supplement – May, 2021 Reviews & Buyers Guide

Milk thistle is often used in herbal supplements to help treat liver issues such as hepatitis, cirrhosis, jaundice, and gallbladder disorders. Its benefits may be beyond that, as many claim it also helps them to encourage heart health by lowering “bad” cholesterol levels, and may even help those with type 2 diabetes.

You may wonder how a delicate, flowering herb can provide so many potential benefits. It’s due to the silymarin in milk thistle, which acts as both an antioxidant and an anti-inflammatory. Some early research even suggests that milk thistle supplement benefits may include aiding those with alcohol-related liver diseases or liver damage from industrial toxins like xylene and toluene.

If you’re curious about the potential benefits of milk thistle and considering adding it to your life, there are a few things you should know:

If you are currently on any medications, discuss whether or not you should add milk thistle supplements to your routine with your doctor, as the herb may interact with your medicine (including some type 2 diabetes medications).

Milk thistle supplements can be taken alongside cholesterol-lowering medications (including statins) and may help prevent the elevation of liver enzymes which is sometimes a side effect of these medications.

Many milk thistle supplements can either be taken orally or added to tea—which can make choosing your supplements a delicious and relaxing treat.

Those who have a ragweed allergy should not take milk thistle supplements, as milk thistle is in the ragweed family and so may cause a severe allergic reaction to intolerant individuals.

Women who have fibroid tumors, endometriosis, or ovarian, uterine, or breast cancers should not take milk thistle, as it may potentially mimic the effects of estrogen. Contact your doctor before you begin taking them.

It’s no secret that with the new, keen interest in alternative health (which is a great thing!) there have come along less than reputable companies that try to jump on the bandwagon without really knowing what they are doing or caring about their customers.
