This option is intended for those who prefer cold shipping for probiotics. Packing will include an ice pack.
It is recommended that probiotics be refrigerated for long-term storage and may lose viability over time at room temperatures. Prothera and Klaire Labs state: Probiotics maintain a relatively high degree of stability at room temperature for up to five months and then gradually begin to lose potency. This suggests that while some probiotics require refrigeration to maintain viability over time, they do not quickly diminish in potency at room temperatures. Products may be taken out of the refrigerator for weeks or even months without a significant loss of viable organisms.
(Please note, Ice packs will lose coolness over time; MorNatural can not guarantee constant temperatures.)
