as required , detailed embodiments of the present invention are disclosed herein ; however , it is to be understood that the disclosed embodiments are merely exemplary of the invention , which may be embodied in various forms . therefore , specific chemical structure and functional details disclosed herein are not to be interpreted as limiting , but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed chemical structure . in a first embodiment , the present invention is directed toward a dry effervescent material or mixture that when added to water , generates one liter of drinkable solution containing molecular hydrogen ( h 2 ) at a concentration of at least 0 . 8 mm , which may be referred to herein as simply hydrogen water . once prepared , such as is described below , the user can consume the hydrogen water orally , such as by drinking . alternatively , the hydrogen water can be applied topically to the skin and hair , such as is known in the art . for convenient use , the effervescent mixture can be formed into a tablet , a powder or a granule . tablets can be sized to provide individual serving sizes of the mixture , that is , the appropriate amount of mixture for a specific volume of water , such as one pint or one liter . similarly , powders and granules can be aliquoted into single - serving - sized packets or cups . to facilitate the following discussion , the effervescent mixture will be referred to herein as an effervescent tablet that is intended to be a single - serving sized quantity of the effervescent mixture . it is understood that the effervescent mixture could be provided in larger or smaller quantities and in other forms known in the art . an effervescent tablet of the present invention includes a base metal , denoted by me in formula i above , an edible non - hydroscopic dry organic acid , and an edible binding - excipient material . when the effervescent tablet is added to a quantity of potable water ( h 2 o ), the base metal me and the organic acid react to produce an aqueous solution with a molecular hydrogen ( h 2 ) concentration of between 0 . 8 mm and 2 . 5 mm and a final ph of between 8 and 10 depending upon the quantity of water , such as depending upon the size of the bottle of water . generally , the effervescent tablet is sized for mixing with between about 200 ml to about 2 liters of water while providing the required hydrogen concentration and ph . for example , since drinking water is often sold in 500 ml bottles , the effervescent tablet can be conveniently sized for use with such quantities of water . as noted above , the effervescent tablet includes a base metal me . generally , the effervescent tablet includes at least 5 mg of the base metal me and up to 200 mg of the base metal me . for example , the effervescent tablet can be formulated to include between 30 mg and 60 mg of the base metal me . the base metal me used in the effervescent tablet is an active non - ionic metallic metal selected from the group consisting of alkaline earth minerals and other metals in their non - ionic metallic state . preferred base metals me have a greater negative redox potential than hydrogen gas ( h 2 ), such as alkali metals and alkaline earth metals . suitable base metals me include , but are not limited to , strontium ( sr ), calcium ( ca ), magnesium ( mg ), aluminum ( al ), manganese ( mn ), zinc ( zn ), iron ( fe ) and combinations thereof . the effervescent tablet includes a quantity of an edible non - hydroscopic dry organic acid . generally , when prepared for dilution into 200 ml to 2 liters of water , the effervescent tablet includes at least about 20 mg of the organic acid and up to about 300 mg of the organic acid . for example , in some circumstances , the effervescent tablet includes between 60 mg and 190 mg of the organic acid . however , the quantity of the organic acid is suitable for stoichiometric reaction with the quantity of the base metal me provided in the tablet . suitable edible dry organic acid include , but are not limited to , organic acids , such as carboxylic acids , which includes maleic acid , succinic acid , malic acid , fumaric acid , formic acid , oxalic acid , all stereoisomers or derivatives thereof , and all forms of alpha - keto acids , polycarboxylic acids and inorganic acids such as boric acids and certain lewis acids . the amount of a selected edible dry organic acid used in a particular effervescent tablet depends upon the acid &# 39 ; s dissociation constant ( pka ) and the number of hydrogen ions ( h +) that can be produced per acid molecule . the stoichiometry of acids is such that they behave as acid / base buffers . when the ph of a solution ( i . e ., water ) is acidic , the acid rapidly reacts with the base metal me to quickly produce hydrogen gas ( h 2 ). however , based on stoichiometry , the reaction will turn alkaline near its completion . the reaction kinetics are sufficient that in 5 minutes the ph is above the acid &# 39 ; s pka , resulting in a near h + concentration of one base 10 log unit above the highest pka of the organic acid , which is near a neutral ph and thus tasteless water . after 10 - 20 minutes the reaction has proceeded to sufficient completion so as to result in a super - saturated hydrogen concentration of between 1 mm and 3 mm . the edible dry organic acid of the effervescent tablet ranges from 100 mg to 500 mg , preferably 100 mg to 300 mg and may include individual acids or any appropriate combinations thereof . the effervescent tablet includes between about 200 mg and about 800 mg of an edible binding excipient material . for example , the effervescent tablet may include between about 250 mg and about 600 mg of the binding excipient material . suitable binding excipient materials include non - hygroscopic and low - hygroscopic ingredients and sugar alcohols . mannitol is frequently used , since it has potential medicinal characteristics and lacks a strong taste . however , other sugar alcohols may be employed . the edible binding material ranges from 200 mg to 800 mg , preferably 250 mg to 600 mg . in the pharmaceutical , supplement and food arts , when tablets , powders and granules are prepared for dilution or dissolution into water , it is common to include compounds known as disintegrants , which causes them to disintegrate and release their medicinal substances on contact with moisture . exemplary disintegrants include but are not limited to starches and organic edible fiber . due to the nature of its ingredients , the effervescent tablet tends to readily disintegrate and mix into solution with the water into which it has been mixed . thus , in preferred embodiments , the effervescent tablet is free of such disintegrants . compounds known as lubricants are also frequently added to tablets , powders and granules , to provide free flowing of the granulates in manufacturing equipment and easy release of tablets from the molds and punches of the tablet presses . exemplary lubricants include but are not limited to magnesium stearate , calcium stearate , stearic acid and sodium lauryl sulfate . because lubrication excipients are hydrophobic and tend to produce insoluble residual suspensions in water , their use is very limited in the effervescent tablets . therefore , in preferred embodiments , the effervescent tablet is substantially free of lubricants ; however , either disintegrates or lubricants may be used . as mentioned before , none of the known lubricant excipients are suitable for producing drinking water additive . however , the present invention provides a novel solution by using fumaric acid simultaneously as an active ingredient , as a flowing agent and as a lubricant when preparing the effervescent tablet of the preferred invention . the lubricating abilities of fumaric acid are achieved by reducing the particle size to 10 - microns and by blending the resulting material in the tablet compounding powder . as noted above , the effervescent material is provided to consumers . when packaged in a sealed container with a desiccant , such as is known in the art , the effervescent material is substantially non - degradable for at least 24 months . in some embodiments , when the effervescent material is sealed with a desiccant , the effervescent material is substantially non - degradable more than 24 months . for example , when provided in proper packaging , the effervescent material is substantially non - degradable for at least 48 months . in another embodiment , a method of making the above described effervescent material for the generation of molecular hydrogen ( h 2 ) in a quantity of water is provided . to make the effervescent material , quantities of the base metal me , the dry organic acid and the edible binding material are provided and then mixed together . the lubricating ingredients are micronized to a size of between 5 microns and 10 microns . to use , the effervescent table can simply be added to potable water . bottled water , including clean tap water , reverse osmosis water , distilled water and all forms of mineral water are suitable waters with which the effervescent tablet can be used . the tablet can be added to any volume of water , preferably between 200 ml and 2 liters of water , and most preferably 500 ml of water . after adding the tablet , the solution should be allowed to rest , sit or percolate for at least five minutes before consumption . preferably , the solution should be allowed to rest for at least 15 minutes , and more preferably 20 minutes . allowing the solution to rest less than five minutes should not harm the drinker , though the solution will be less palatable than when the solution rests for a full five minutes . it is to be understood that while certain forms of the present invention have been illustrated and described herein , it is not to be limited to the specific forms or arrangement of parts described and shown .
convenient , inexpensive and portable effervescent tablets that the consumer can add to water to generate hydrogen - rich water just prior to drinking . the effervescent tablets include a base metal and an edible acid that , within about 5 - 10 minutes of mixing , generate a palatable aqueous solution having about 0 . 8 mm to about 3 mm hydrogen and a ph of 8 - 10 .
