Why this is confusing
Airport security decides what can go through the checkpoint. Your airline decides baggage handling rules. Border and customs decide what you can bring into the country. Those are three different checks — and an item can be fine at one and refused at another.
Triple check before you pack
Airport security, airline baggage rules, and destination border rules are three different checks. Passing one does not guarantee passing the others.

Frequently asked questions
Do I need to declare vitamins and supplements when arriving in Ireland?
Not usually, for personal-use quantities. Commercial quantities or anything in a restricted category should be declared. Check the current Ireland customs page before travelling with more than a typical personal amount.
Are the rules the same flying back from Ireland to United Kingdom?
Not necessarily. Airport security rules are set by the departure airport, and customs rules are set by the destination. The return-flight checks can look quite different from the outbound — check both sides before you pack.
