RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/859,398, filed on Jul. 29, 2013, which is hereby incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     1. The Field of the Invention 
     This invention relates to oral supplements for recovery from physical activity, and more particularly, to powdered drink mixes facilitating recovery and replenishment to the body after strenuous physical exercise or performance. 
     2. Background 
     Numerous products are currently available for helping a person recover from physical activity. These products may include attempts to replenish solutions and nutrients lost or used during exercise. These products can include a wide variety and combination of compounds to help achieve the desired effects. These products can come in a wide variety of forms, including without limitation, beverages, gels, powders, etc. 
     Certain products have attempted to apply the known benefits of nitric oxide and creatine-phosphate to recovery after physical exercise. Substantial literature is available on the subject of nitric oxide and its effects on human tissues. 
     Nitric oxide and creatine-phosphate are considered unstable molecules. This makes it difficult to develop a product that can consistently promote the formation of, or provide usable, nitric oxide and creatine-phosphate to a person. What is needed is product that provides a comparatively efficient way to promote production of nitric oxide and creatine-phosphate usable by human cells and tissues. 
     BRIEF SUMMARY OF THE INVENTION 
     In accordance with the foregoing, certain embodiments of a product, compound and method in accordance with the invention provide an oral product that can be consumed by a person to facilitate and promote the production of nitric oxide and creatine-phosphate, especially after physical exertion. The oral product may be suitably formulated to promote production of nitric oxide and creatine-phosphate in human cells and tissues. 
     In one embodiment, the oral product may be formulated to be a powder that is mixed with a liquid in preparation for consumption. The powdered formulation may be mixed with water, followed by a brief but necessary allotment of time for the powdered formulation to completely react in the water. The liquid may also be milk, juice, or some other suitable beverage. The resulting mixed beverage may then be consumed by a person or user to facilitate production of nitric oxide and creatine-phosphate that is usable by the person, especially to help recover and rejuvenate the person after physical exertion and reduce or relieve muscle soreness.

     The mass percentage of the components that comprise a powdered oral product may be adjusted plus or minus 20%. Other components may be added as desired, such as flavors or other preservatives or other dietary supplements. 
     The amount of arginine and creatine used is intended to have a molar ratio between approximately 1:1 and 5:1. Organic acids help provide maximum solubility of active substrates like arginine and creatine, which helps solubilize arginine and creatine at specific molar ratios. The amount of organic acids used is intended to provide a specific pH range, which pH range is generally considered to be lower than a pH of 6, or approximately a pH of 5, but may be anywhere between an approximate pH of 8 and an approximate pH of 2. 
     The amount of simple sugars used may have a molar ratio of approximately 1:5 or 5:1 in any combination with arginine, creatine, and zinc ions. 
     Certain components can be excluded while still allowing the powdered product to provide the intended result. For example and not by way of limitation, vitamins provided as part of the formulation may be supplied by a separate source other than the oral product. 
     However, the presence of zinc in the form of zinc ions is instrumental in the effectiveness of any oral product. Thus, zinc in the form of zinc ions should be included in combination with any or all of the component ingredients of the oral product. 
     Simple and complex carbohydrates may be included in the formulation of the oral product to help promote recovery from physical exercise. 
     In one embodiment, the oral product may be formulated in powdered form. The oral product may then be mixed thoroughly with a liquid, such as water. The mixture should be allowed to stand for at least one minute before consumption, and preferably between approximately one and five minutes. 
     As shown in  FIG. 1 , experimental data can show the presence of nitrite in the person&#39;s saliva after consumption of the mixture. The correlation between nitrite in saliva and nitric oxide production has been demonstrated previously in separate, peer reviewed literature. 
     As an example, a person combined the powdered formulation as generally described herein with water. The powdered formulation and water were stirred to form a mixed beverage. The mixed beverage was allowed to stand for approximately three minutes. The person then consumed the mixed beverage. 
     After approximately five (5) minutes, when monitored for nitrite via the Greiss test, the person&#39;s saliva can be shown to have produced a measured increase and clearing of nitric oxide over a 90 minute time period. This positive test demonstrates that nitric oxide had been produced, and was present in the person&#39;s system.
An oral product that includes an amino acid nitric oxide precursor and a compound capable of providing zinc ions. The product can be formulated as a powder and mixed with a liquid in preparation for consumption by a person. The powdered formulation may be mixed with water followed by a brief but necessary allotment of time for the powdered formulation to completely react in the water. The resulting beverage may then be consumed by a person or user to facilitate production of nitric oxide and creatine-phosphate that is usable by the person, especially to help recover and rejuvenate the person after physical exertion and reduce or relieve muscle soreness.
