Here is the information from the VAXA web site on manufacturing standards. It can be found online at http://www.vaxa.com/manufacturing-standards.cfm
There Are 1037 Nutritional Manufacturing Facilities in The U.S., but only one Passed Our Rigorous 7 Step Examination. Less than ½ of 1% of the nutritional manufacturing facilities in the country match the exacting standards followed in the Växa facility. Our products are manufactured in a lab that follows standards beyond those suggested under Good Manufacturing Procedure (GMP) guidelines.
No Contamination The manufacturing lab is a clinical environment with all stainless steel construction. To clean the lab we utilize UV sterilization, carbon filtration, reverse osmosis, ozone injection, mix bed de-ionization and boiler kettle our own water. This procedure is above kosher requirements.
No Contamination Each room has its own air handler that completely exchanges the air 50 times per hour. Pure, clean air is a critical element in manufacturing a pure product. There are so many contaminants in the air that a state of the art air scrubbing system is a necessity. Many facilities just have a dust handler and rely on the air conditioning system to fight to replace the air. You might as well make the product in the parking lot. The temperature is at a constant 71 degrees and the humidity is less than 35%.
Every Capsule Has the Same Ingredient Mix The key element of our manufacturing process is particle sizing. Simply put, all of the elements come in different particle sizes. Picture BBs, ping-pong balls, golfballs, baseballs, softballs, and basketballs. Improper mixing yields batches that have all of the basketballs balls at the top and the BBs at the bottom. This would mean that each capsule has a different mix of ingredients (those early in the loading process - too many basketballs). We use cold process pulverization to take all particles to the same size - everything is a BB. Smaller particle size means that the body assimilates the elements more readily.
Capsules Have Longer Lasting Potency The product is weighed and blended in a static and gravity free environment. This incorporates 100% batch involvement in the mixing process with no dead spots. While in the blending process, the ambient air has been removed and replaced with stable nitrogen, which is heavier than air and reduces oxidation and process contamination. The bulk material is weight validated to assure batch size compliance, then formulation and quality control verified for batch uniformity. The lab signs off on weight sheets to make sure that everything that was supposed to go in went in.
Capsules are Loaded One at A Time In the encapsulation department, pharmaceutical standard, GMP certified machines employ the dose tamping method. Powder goes into the machine then is tamped with pins into the capsule to the milligram of accuracy. This process is done one capsule at a time. During this process, at 5- minute intervals, a person will test to validate quantities. The capsules are polished, dust is removed, and they are hand inspected to see that they are not dented, scratched, or broken. The finished product is analyzed using high-pressure liquid chromatography, which creates a quantitative analysis of a compound. Then a mass spectrometer is used to create a qualitative analysis. This creates the blue print that all future capsules must match.
No Short Cuts At the end of the production process, checks are run to insure that the product weighs what it should. Industry standards allow +/- 5% failure tolerances. We insist on a tolerance of +/- 1%. Many manufacturers cut corners here. It is in their interest to do so as 5% less material in each capsule adds up to serious costs saved over time.
In the end, each batch comes with a certificate of analysis and has a National Drug Control number. Once it is manufactured and packaged, the product is then tested by lot to ensure quality control, stability, consistency, weight, and content. Time series and dating analysis are performed twice on all lots, first at the lab and then when received as a finished product by Växa. Strict controls of inventory dating and ongoing computer evaluations are performed daily, while total rechecks of inventory are performed each month.
VAXA's manufacturing standards are the highest in the industry.
