Claim:
A method of preparing a mixture for quality control of 0.1 g glycine tablets for sublingual application, the tablets having stress-preventative, anti-stress, nootropic, and neuroprotective effects, the tablets being suitable for single administration or for long-term treatment, each tablet comprising microcapsulated glycine comprising non-agglomerated crystals of amino-acetic acid covered with a polymeric film of water-soluble methylcellulose, each tablet further comprising magnesium stearate, each tablet having a crush resistance of at least 10 N and no more than 30 N, the method comprising: providing said tablets that have been porphyrized; obtaining the mixture by mixing 2.5 g of porphyrized tablets in 250 mL purified water for 20 minutes at a temperature of 37° C. in an apparatus using a paddle rotation speed of 150 revolutions per minute; allowing the mixture to stand for 10 minutes; and measuring a light transmission coefficient of 4 mL of the mixture for a 10 mm thick layer in a container relative to the light transmission coefficient for purified water using a light transmission spectrophotometer at a wavelength of 700±2 nm.
