Collagen
TL;DR
something.
Well worth taking but not essential. A type of protein.
From the Greek for 'glue' (kólla) and 'gen' for producing.
Particularly beneficial for some groups (increasing bone mineral density in menopausal women for example).
Vitamin C is essential to biosynthesis.
You don't need to worry about types, particularly if taking with vitamin c - your body will synthesize what it needs from other types (or from other protein you consume). Most of the collagen in the body is type I.
Also recommended you get enough vitamin d and zinc.
Good old bone broth.
Made from cow skins, or marine animals.

Quality
As with all supplements - buyer beware. It's quite common for supplements to be contaminated with a variety of impurities, often in the form of heavy metals, and/or contain far more or less of the ingredients stated on the label. There's no simple rule of thumb to avoid this, such as avoiding cheap or imported products; expensive or well-known brands produced in-country may be just as bad. Ideally you should take some time to find products (if you can) that;
- have been laboratory tested on behalf of the manufacturer by a reputable body or company that operates in your country or region (here's an example of a Peak Supps creatine supplement available on Amazon in the UK which has been tested by Eurofins: Creatine Monohydrate Powder 1Kg | Pure Micronised | Packaging May Vary - see pictures 3 & 4)
- have been laboratory tested by an independent testing company that ranks product purity and ingredient amount accuracy on behalf of consumers (usually funded by affiliate sales of those products). An example of this is Labdoor.
