NAD+ gelling in fridge after reconstitution

The gelling happens when the vial sits too close to the fridge fan and gets too cold, causing the NAD+ to come out of solution as a cloudy mass or white grains. Moving the vial to a different spot or using a plastic box stops the problem, and letting it warm to room temperature followed by filtering restores a clear liquid. People report no issues when reconstituting 500 mg with 3 ml or 1000 mg with 6 ml of bacteriostatic water.

• Direct cold airflow from the fridge fan triggers gelling even above freezing.
• Warming the vial for 15 minutes and rolling it returns it to liquid, though particulates may appear.
• Filtering removes the grains and the solution remains usable afterward.
• Higher reconstitution volumes reduce the chance of precipitation.
• Buffered NAD+ may behave differently but still gels under cold conditions with standard bacteriostatic water.

Whether buffered NAD+ needs a different pH or solvent than ordinary bacteriostatic water.

Nothing here is advice.
