Dr. Derrick DeSilva

Chief Wellness Officer at Zilis

Dr. DeSilva, along with our team of experts, developed our exclusive and proprietary full spectrum hemp oil, UltraCell, using micelle and liposomal technology to make the product 100% water soluble. We all know that water and oil don't mix. It's a widely known fact that oil-based supplements are poorly absorbed by the body. Through our proprietary process, every compound available is delivered deep into your system. More bio-availability means more health benefits and a faster onset of action.
