Most probiotics we stock are tested to retain potency if exposed to up to 30+ degrees for a period of time. See downloads:

For precautionary reasons, we typically send orders containing these products early in the week, not on Thursdays or Fridays.
BioCeuticals has advised:
"During testing, the Probiotics are exposed to temperatures of 37 degrees or more for over 4 days and there was only a slight loss of bacteria. To cater for this potential loss we overpack all of our products by 20-50% so that at the time of expiry (2 years) we can guarantee that what we say is on the label is actually in the product."
BioConcepts (who make Orthoplex products) has advised:
"Their probiotics will retain potency if exposed to room temperatures for a period of time (eg. the technical team from Orthoplex advised their Multiflora would withstand temperatures for up to 10 days without affecting potency. SAMe would withstand temperatures of 30 degrees for up to 7 days without affecting potency)."
BioMedica has advised:
“Stability testing has shown that after 3 months, the survival rates of the probiotic strains in TriGenex are similar when they are stored at 25°c, as when refrigerated at 5°c. In addition to this, significant overage is used in the product to ensure that the CFU count will meet the levels stated on the label at expiry.
Many individual strains in these products tolerate ambient temperatures quite effectively and show little viable cell loss when kept for 24 months (2 years) at 23-25°C. Therefore it is BioMedica’s assertion that the therapeutic potential of our probiotics will be maintained irrespective of transit delays and resultant melting of cold packs. Should the product be exposed to lengthy delays or extreme temperature changes, this may need to be re-assessed.”
Bio-Practica has advised:
"Our ProBiome (D-Lactate free) probiotics show excellent stability and high survival rates for each strain during manufacture, transport and storage, even when kept unrefrigerated. The combination of the overage above the label claim (at the time of manufacture) and the unique robustness of each strain, ensure ProBiome (D-Lactate free) Probiotics have excellent stability during their shelf life."
Eagle has advised:
"Results indicate, exposure to ambient (non-refrigerated) temperature for a period of at least 1 month would not impact the shelf life of the product."
Medlab has advised:
"Can be unrefrigerated for up to 4 months at 25°c without losing potency". Probiotics do not die off when stored at room temperature, however, refrigeration can maximise long-term viability.
Metagenics has advised:
Metagenics have conducted testing to ensure their probiotics can withstand exposure to temperatures without losing potency.
- 40 degree temperatures for up to 48 hours
- 30 degree temperatures for up to 14 days
- 20 degree temperatures for up to 4 months
- 4 degree temperatures for up to 2 years
Mutaflor has advised:
"The probiotics contain viable bacteria in a high concentration. It can remain at room temperature for up to 72 hours without loss of efficacy. Thereafter the CFU will begin to diminish and therefore one could expect a reduced efficacy."
Nutrition Care has advised:
"For our probiotics with the exception of SAMe, generally recommend no more than 3 days storage under non-refrigerated conditions not exceeding 30°c. SAMe 200mg and 400mg has undergone extensive testing and found both remain stable after 6 months of exposure to 30°C at 65% relative humidity".
Rosita has advised:
"There are 2 ‘best before’ dates on the bottle. The first is Fridge, the second is Freezer.
If the product was in the fridge the entire time you would use the fridge date (1 year from production) and if the product was in the freezer the entire time you would use the freezer date (3 years from production)
We suggest that all oils are stored away from light and heat. Ideally in a dark freezer or dark fridge."
Spectrumceuticals has advised:
"Probiotics are viable for up to 28 days outside the fridge at ambient temperature and up to 14 days at 40 degrees Celsius."
