Tiffany Davis

I considered myself underweight after becoming a mother for the first time in 2014. Giving birth to my son is what helped me bring to life Girlsupps (formerly Nutrithick). I saw a gap in the market for weight gain products created for women like myself who were looking for alternative, natural herbs and supplements with holistic, clean ingredients. 3 years of research later, I founded Girlsupps in 2017.

With my desire to see women worldwide confidently embrace their bodies every step of the way, Girlsupps was founded for women, by women. Our brand is here to inspire and support women on a healthy weight gain journey. We’re dedicated to building community in the best way possible to help you reach your best #Thick potential.
