very good value and speedy delivery

01 July 2015

Comment as for cod liver oil plus the tablets following the cha ge to the blister pack don't seem to be as strong as those in the plastic containers.

Thank you for your review - We're sorry you're not a fan of our letterbox-friendly blister packs - We had a lot of negative feedback about our tubs and have moved our whole range over to foil-sealed blister packs to ensure uncontaminated, fresh tablets right through the pack.

It's easy to find the product you want, however the packaging necessitates tablets being pushed out of the foil sheet. This is very difficult for arthritis sufferers, I buy and take this product because I have arthritis!
