Extract ratio (e.g. 30:1) – 30 kg of raw material were concentrated into 1 kg of extract. It describes concentration, not strength.
Standardisation (e.g. 30% polysaccharides) – the extract is tested so that a stated share of a named compound is present in every batch.
Chelate / bisglycinate – a mineral bound to two molecules of the amino acid glycine. The label shows the total compound weight and the elemental mineral it yields.
Proprietary blend – a group of ingredients listed under one total weight, so the amount of each is not disclosed. SLEEP has none: every amount below is the amount in one sachet.
