The phrase signifies a type of dietary supplement characterized by its high-quality collagen peptides and a production process that minimizes or eliminates potentially harmful additives and contaminants. It typically refers to collagen sourced from grass-fed, pasture-raised animals or sustainable marine sources, processed without harsh chemicals, and tested for heavy metals and other impurities. An example would be a bovine collagen powder sourced exclusively from grass-fed cows, certified organic, and third-party tested to verify its purity and absence of pesticides.
The appeal stems from a growing awareness of the potential benefits of collagen supplementation for skin health, joint support, and overall well-being, coupled with increasing consumer demand for transparency and clean ingredient lists. Historically, collagen supplements often contained fillers, artificial sweeteners, or were derived from sources with questionable ethical or environmental practices. The emergence of products prioritizing purity and ethical sourcing addresses these concerns, offering a more appealing option for health-conscious individuals.
