Our Broad Spectrum tinctures are formulated with proprietary micelle nanotechnology. This allows for up to a 900% increase in absorption rate and bioavailability. Broad Spectrum means the cannabinoid profile consists of >90% CBD. The remainder consists of other minor cannabinoids to produce what is known as the entourage effect. The entourage effect is a theory that cannabinoids work better together rather than in isolation. The difference between Broad Spectrum and Full Spectrum is that the THC has been removed. This is ideal for people subject to THC testing.
