Cold filtration retains bioactive peptides
Filtering whey at low temperatures means denaturation is limited. This protects the vital bioactive peptides which can support immune health and glutathione synthesis, like lactoferrin and serum albumin. They’ll remain bioactive in their original 3D structure, meaning your body can use them more effectively.

No synthetic hormones or antibiotics
One of the concerns with conventional whey protein is that it may contain pesticide residues from dairy farming. These can contribute to inflammation and oxidative stress, both of which can deplete glutathione stores. (20,21)
Organic whey protein is sourced from farms which are strictly free from pesticides, as well as hormones and routine-use antibiotics, making it a cleaner, more effective choice.
The bottom line
If you’re looking to increase your glutathione levels naturally, cold-filtered, non-denatured, grass-fed whey protein seems to be one of the best protein powders compared to more harshly processed alternatives.
With higher cysteine content, more bioactive proteins, and no presence of pesticides, it can be a clean, effective way to support production of your body’s master antioxidant.
