Is the collagen blend suitable for vegetarians?
No, it is marine collagen and comes from fish. Not suitable with a fish allergy either.
How do I compare a blend with a single ingredient?
Read the amounts of each active on the label rather than the name on the front. Blends are harder to price-compare, which is the trade for the convenience.
How long should I take these for?
The collagen over months. The others consistently rather than occasionally – a few days tells you nothing.
Can I take more than one blend?
Check the ingredient lists for overlap first, and ask a pharmacist if you take prescribed medication.
