STABILITY TESTING
Summit Nutritional Laboratories strives for the peak of quality. We base our success on achieving total client satisfaction with timely, accurate results.
SHELF LIFE
Determining shelf life is an important aspect of developing and selling finished products. Our stability program is an excellent way to monitor how your product performs to see if it continues to meet label claim as the product ages.
Throughout the lifetime of the study, samples are preserved in climate-controlled conditions as appropriate to specific sample storage requirements. Room temperature studies are maintained at 20 – 25 °C and 60% relative humidity, refrigerated studies are maintained at 5 °C, and frozen studies are maintained at -20 °C. We also offer an “accelerated” time study where samples are stored at 40 °C and 75% relative humidity to simulate product aging on a quickened timeline.
In a typical stability study, testing is conducted once the sample is received, as well as at 3, 6, 9, 12, 18, and 24 months (accelerated study time points are 0, 3, and 6 months, approximating a 24-month real-time study). However, we can modify the testing points to accommodate any needs you may have.
Here is an example of what a typical stability study may look like, with results for Vitamin C, Vitamin D3, and Calcium charted over time with respect to their label claim:
From this 2-year stability study, it is observed that the product maintains its label claim for both Vitamin D3 and Calcium, but the Vitamin C potency dips below the label claim at the 24-month timepoint. The data allows us to determine that while a 2-year shelf life would be acceptable for most of the components of the sample, an 18-month expiration date is more appropriate for this particular sample to still be guaranteed to meet its label claim.
