Why does Milk Thistle Gold contain tapioca maltodextrin and rice concentrate?
At NutriGold, we are philosophically opposed to the use of chemical additives and synthetic preservatives in our products, which is why we avoid magnesium stearate, silicon dioxide, and other commonly-used additives derived from GM ingredients like corn starch, corn maltodextrin, and soy lecithin. The tapioca maltodextrin and rice concentrate are plant-derived alternatives to chemical additives and added to the product to ensure finished product quality and integrity.
How does NutriGold ensure the purity of the ingredients used in its Milk Thistle Gold product?
At NutriGold, our first priority is consumer safety, which is why we verify that raw materials used in our products as well as the finished products themselves meet industry-defining quality and purity standards.

We take these results from third-party labs and summarize them in lot-specific Certificates of Analysis that are freely available in the spirit of authentic transparency on the product pages on our website so consumers can make informed purchasing decisions.
