This is the one - https://www.amazon.co.uk/JOINTSURE-Supplements-Advanced-Strength-Ingredients/dp/B078XHF8GM?th=1 I bought the pack of 300 for just under £30, I notice they are also doing a 3 for 2 on it. Timber gets one a day (8 kilos) and that costs just under 10p a day. And, on an additional note, Mr F decided he should be on them too (human version, I'm not that cruel). I am still waiting to see the effects on him, it's only been a week ... I also got Timber a bioflow magnetic collar. People seem to say either that they are fabulous, or they make no difference at all; but I thought it can't do any harm and if it does help, it's worth every penny (about £25).
