Ask yourself: why are the other colloidal Gold products in dark bottles where you can't see what you are getting? Colloidal Gold is not photo-sensitive, so why? True colloidal Gold should be a crystal clear ruby red color as you see this 1 US Gallon (128 Fl Oz) heavy duty HDPE jug of MediGOLD is. MediGOLD is true colloidal Gold; it is 20 ppm of 99.99+% pure Gold as bio-available nanoparticles -colloidally suspended in pure, pharmaceutical grade water. MediGOLD's nanoparticles are only 2 to 7 nanometers (radii) and thus 100% bio-available. It is true colloidal Gold with no color added, no ionic Gold, no stabilizers, no protein and no preservatives present. The bottle is triple sealed: 1) opening is sealed with an induction foil sealing disk covering the opening which reads "SEALED FOR YOUR PROTECTION", 2) the neck of the bottle is capped, and 3) the cap is sealed to neck of bottle with a heat shrink neck band that also reads "SEALED FOR YOUR PROTECTION". Shelf life should be several years for unopened bottles, and several months for opened bottles. DO NOT ALLOW THIS PRODUCT TO FREEZE...the product will turn clear as all of the Gold nanoparticles will no longer be colloidally suspended - even after the frozen product thaws. Recommended daily serving is one tablespoon (15 mL) for adults, or one teaspoon (5 mL) for children, taken on an empty stomach to maximize adsorption in the gastro-intestinal tract. Wait 20 to 30 minutes before eating or drinking. One tablespoon provides 300 mcg of Gold, one teaspoon provides 100 mcg of Gold. Ships from USA via DHL with all shipping and VAT pre-paid.
