MediGOLD True Colloidal Gold dietary supplement has been a trusted brand of colloidal Gold dietary supplements across the globe for well over a decade now so you can order and consume MediGOLD with confidence! It is made in the USA where it is manufactured, tested and bottled using current Good Manufacturing Practices (cGMPs) by Nutraneering in our facility in Irvine, California on Technology Drive right next to some of the greatest biotech companies in the world. Production, documentation and quality control (QC) testing are overseen by our founder - Biochemist and former Research Scientist at NASAs Water and Food Analytical Lab (W.A.F.A.L.) in building 37 (the Life Sciences Building) at the LBJ Space Center Houston. MediGOLD consists of ultra-pure Gold nanoparticles colloidally suspended and dispersed in pharmaceutical grade pure water - that's it (0.00% chemicals). The Gold nanoparticles in MediGOLD are made from 99.99+% pure Gold - this is much purer than 24K Gold which is only 99.9% pure (max). Purity is critical as the impurities in 24K Gold (the .10+% %) can include Lead, Arsenic, Cyanide, Hexavalent Chromium, Mercury and more. MediGOLD is a red, odorless, tasteless liquid. MediGOLD's Gold nanoparticles have an average size of less than 3 nm in diameter - making them not only 100% bio-available, but the smallest Gold nanoparticles on the globe - so small they easily pass across the blood brain barrier where they can be used by the brain as well as by any organ or cell in the body. MediGOLD is safe to consume as a dietary mineral supplement take as directed as taking more is not likely to yield any additional benefit. Nutraneering's liquid dietary supplements are significantly better than pills please see attached image for proof. You can find more heavily advertised, even more expensive true colloidal Gold supplements, but we are confident that you will not find one better - at any price. Shipping to anywhere in the USA is free including AK & HI.
