Cold Crush

Genexa was founded by two dads, David Johnson and Max Spielberg, who wanted cleaner, safer medicine for their families. Frustrated by the artificial dyes, sugars, and preservatives in common medicines, they set out to create a better alternative. Their goal was simple: to make medicine with the same effective active ingredients as leading brands but without unnecessary and potentially harmful artificial fillers. Today, Genexa is the first clean medicine company, committed to using responsibly sourced, high-quality ingredients while meeting the highest FDA standards. Every formula is carefully crafted to support you and your family's health—without anything artificial getting in the way.
