Recognising quality
How 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.
12 minReadWhen 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.
6 minReadIs a raw material certificate sufficient as proof of quality?
A raw material certificate evidences the tested batch of the raw material, not the filled product. Processing, filling and storage lie in between.

What is the difference between fish oil content and omega-3 content?
The fish oil content describes the amount of oil, the omega-3 content only the share of EPA, DHA and DPA within it. Two capsules with 1,000 mg of oil and two capsules with 1,000 mg of omega-3 are therefore not the same.
6 minReadHow do I read EPA, DHA and DPA on the label correctly?
Watch three things: which reference unit the values relate to, whether EPA and DHA are reported separately, and whether DPA is stated at all.

Shelf life & protection
What happens to omega-3 after the pack is opened?
Once opened, the oil is exposed to oxygen and light. Oxidation values rise from that moment on — regardless of how good the value was at the time of filling.
7 minReadBottle, blister or sachet — what protects omega-3 better?
The less often the oil comes into contact with air after first opening, the more slowly the oxidation state rises. An individually sealed portion is opened exactly once and then fully consumed.
6 minReadAnalytics & oxidation
What is TOTOX and why does the value matter?
TOTOX combines the peroxide value and twice the anisidine value into a single figure. A low value means the oil was little oxidised at the time of measurement. It does not mean it stays that way.
9 minReadHow are heavy metals, PCB and dioxins assessed in fish oil?
These substances are analytically tested as contaminants and set against the applicable maximum levels. Missing disclosures do not mean no contaminants are present — they mean nothing was published.
7 minReadMolecular forms
What is the difference between rTG, TG and EE?
TG is the natural triglyceride form, EE the ethyl ester produced during concentration, and rTG the triglyceride form re-esterified from it. The form influences concentration and uptake, but is not a quality verdict on its own.
8 minReadHow well is omega-3 actually absorbed?
Bioavailability describes which share of an ingested substance becomes available to the body. For omega-3 the molecular form influences the pathway, but dose, the meal and the person's baseline also play a role.
