Recognising quality

Label, analytics and proofs — four articles for a systematic review.

1. 1How do I recognise a high-quality omega-3 supplement?Not by a single figure. A high-quality supplement shows three things: verifiable disclosures on the label, analytics on the finished product, and packaging that protects the oil until it is taken.Recognising quality
2. 2When is an omega-3 supplement highly concentrated?Highly concentrated means: a large share of the filling oil consists of omega-3 fatty acids. Concentration tells you how much oil is needed for the same amount of omega-3 — not how good the product is.Recognising quality
