The nutrients in intravenous IV Drips are 100% bioavailable, whereas the digestive system may only absorb 10-30% of nutrients when taken in supplement form
Injectable peptides require more handling care than oral supplements but deliver superior bioavailability
If you havent already, I strongly encourage you to read this Washington Post Op-Ed as Grant Verstandig and Roger W
Research using MT-1 in cell systems expressing MC1R variants associated with red hair and fair skin has characterised reduced cAMP signalling responses, impaired MITF activation, and decreased melanogenesis , documenting the functional consequences of loss-of-function MC1R polymorphisms at the receptor signalling level and establishing the molecular basis for the reduced photoprotective melanogenesis capacity associated with these variants
Consider it an investment
Moreover, the same study found that patients with severe enteritis showed high abundance of Shigella and Lachnospiraceae Clostridium
