We are not aware of any testing or clinical trials that have been conducted to determine the impact of freezing Ascophyllum nodosum with regards to the dental and/or nutritional benefits.
Anecdotally, customers that have frozen Simply Seaweed have told us it doesn’t appear to alter the product’s efficacy.
If Simply Seaweed is mixed with wet food prior to freezing, this may result in the product swelling (due to rehydration) and going slimy (due to the alginates). This is normal and to be expected, due to the natural composition of the seaweed.
