Protiva was developed by leading, board-certified, OBGYNs. Protiva uses Porcine Collagen because porcine is a 98% DNA match to humans vs cattle (used in most collagens) which is only a 70% DNA match to humans, Our collagen is sourced from sustainable and ethically farmed sources, in the EU, manufactured in the USA, and our packaging is fully recyclable. The more you learn from published studies about collagen’s potential benefits for skin elasticity, hair support and wound healing, we hope Protiva will benefit you and your family the way it has ours.*
