2Finding the right protein powder to meet the individual needs of your body can be difficult, especially with so many brands flooding the market with low-quality, poorly-dosed ingredients. Such powders may have a pronounced negative effect on the health of the liver – the body’s primary detoxifying organ. Thorne Research plans to change all this with their MediClear line of liver-friendly protein powders. MediClear-SGS also features unique antioxidant protection via Sulforaphane Glucosinolate.

  • Based in natural rice protein and pea protein isolate.
  • Sulforaphane glucosinolate is a cutting-edge ingredient for antioxidant and anti-inflammatory support.
  • Contains notorious other liver health support ingredients like curcumin, milk thistle, and green tea.
  • May provide a useful nutritional boost for a variety of athletic and exercise activities.
  • Delicious chocolate flavor is derived in part from real cocoa!

The Importance of Finding a Quality Protein Powder

Protein powders can be an extremely useful tool for athletes, gym rats, and others who engage in regular workout and exercise routines. However, not a lot of people know that powders which are made from low quality ingredients might pose a substantial threat to the health of the liver. As the body’s central detoxifying organ, proper liver function is essential to keeping the body cleansed and protected from toxins, free radicals, and other harmful bodily invaders that may cause oxidative stress and imbalance.

So, how to get all of the energizing and nourishing benefits of protein powders without also exposing the liver to these potential harms?

Quality protein powders, like the rice and pea protein isolate contained in this formula, are essential, not just for optimal workout support, but also for liver health. Some of the most popular supplement brands use low quality protein sources which tend to be poorly absorbed in the digestive tract, making them less useful for workout support and more stressful on liver detoxification processes.

To counter this, MediClear-SGS only uses protein sources which are widely acknowledged as being safe and absorbable in the body. In addition to quality protein sources, this amazing powder also contains a unique blend of liver health support nutrients.

Ground-Breaking Ingredients for Liver Support

In 1992 at the John Hopkins University School of Medicine a substance known as sulforaphane glucosinolate (SGS) was found in high concentrations within broccoli. It was also found that this substance may be the primary source of the amazing nutritional support properties that make cruciferous vegetables like broccoli a health and wellness dietary staple.1

The leading research seems to indicate that SGS provides nutritional support via antioxidant and anti-inflammatory mechanisms. These include the induction of numerous enzymes, including glutathione transferases (GST), which serve as antioxidant response element (ARE) targets; as well as being heavily involved in xenobiotic detoxification.

In addition, SGS’s anti-inflammatory properties are rooted in the inhibition of cytokine production.2 All of these supportive roles may be used to aid in the natural protection and function of the liver.

Not only does Thorne Research’s MediClear-SGS contain this cutting-edge antioxidant and anti-inflammatory support compound, it also contains a number of other important ingredients which may aid in liver health. These ingredients include milk thistle, green tea, N-acetyl-L-cysteine, and curcumin.
