Glutathione is the most abundant antioxidant in the body and our first line of defense against free radical damage and infections.

The antioxidant also has other benefits including cognitive support, and it’s the cognitive-boosting aspect of glutathione the people behind Thorne Glutathione SR chose to capitalize on.

Glutathione SR is advertised as a revolutionary supplement that can support optimal levels of glutathione in the human body.

Maintaining optimal levels of glutathione appears to be critical for supporting cognitive function as we age. Aging tends to lower glutathione levels naturally, which can lead to increased oxidation and illness.

What’s Inside?

3) What’s Inside Thorne Glutathione SR?

The single key ingredient in Glutathione SR is simply a reduced form of glutathione.

Glutathione is the most abundant antioxidant in the body. It removes toxins, reduces stress levels, and helps with long-term brain health.

Glutathione protects our cells by:

  • Neutralizing oxygen molecules
  • Forming a special enzyme with selenium that protects against free radical damage
  • Providing a layer of protection for our organs
  • Possessing an anti-aging effect

The reduced form Thorne used is to help it be absorbed faster, although we think the dose is too small for the claimed benefits, especially as recommended doses start from 250 mg.

However, the company claims that due to the sustained-release properties of the formula, their glutathione is protected from stomach acids and helps maintain adequate glutathione levels in the blood.

4) Does Thorne Glutathione SR Work?

Glutathione supplementation isn’t new. In fact, many wellness supplements use glutathione for different functions including antioxidant protection, cell health and repair, skin and liver health, and some form of neurological conditions such as Parkinson’s disease.

However, we’re not sure if the dose can carry the load of all those claimed benefits. Most research papers use upwards of 250 mg while others recommend 500 mg per day to maintain circulation.

Judging from what we’ve seen, Glutathione SR may not be as potent as it claims.

Final Thoughts

8) Final Thoughts on Thorne Glutathione SR

Thorne Glutathione SR is backed by one of the most popular brands in the supplement industry and the science surrounding glutathione supplements is pretty much solid at this point.

The formula is transparent and makes use of a form of glutathione that offers high bioavailability. However, we think the dose per serving (1 capsule, 175 mg) is too small for the intended effects.

Users will have to follow the serving directions and go for at least two capsules per day to get the effects they see on the website. Unfortunately, this will cut the life-span of one bottle in half, making it a pricey purchase.
