protocol capsules wadebridge (Egloshayle PL27)

Can anyone make use of a large tub of "PROTOCOL" brand collagen capsules. I have 2 tubs of 240 capsules dated best before end February 23 but that just means the efficacity will gradually wane. I opened one tub and took a couple of dozen but don't get on with them at all The other tub is sealed.
