PHOSPHOLIPIDS / EPA + DHA / CHOLINE / ASTAXANTHIN

Antarctic krill oil

Krill oil brings together omega-3 fatty acids, phospholipids, choline and naturally occurring astaxanthin. This ingredient profile distinguishes it from fish oil.

Both omega-3 quantity and lipid form matter to the description of the oil. In krill oil, a proportion of EPA and DHA is associated with phospholipids, including phosphatidylcholine. The amount of each component depends on the selected ingredient and requires specification evidence.

Ingredient profile

EPA and DHA
Long-chain omega-3 fatty acids present in krill oil. State the quantity of each separately.
Phospholipids
Part of the oil’s lipid fraction. Phosphatidylcholine is one phospholipid and contains choline.
Choline
Present within phosphatidylcholine. Phospholipid mass must not be presented as an equivalent amount of choline.
Astaxanthin
A carotenoid naturally present in krill oil. Its concentration is an ingredient-specification parameter.

Quality documentation

EPA and DHA, phospholipids and choline are not independent fractions that can simply be added together. Present values in line with the analytical method and specification conventions.

Product information explained

Krill oil: a complete composition profile.

A krill product is described by more than its oil quantity. The selected specification is the reference for its EPA, DHA, phospholipids, choline and astaxanthin information.

Oil per capsule
State the oil fill and distinguish it from the total capsule mass, which includes the shell. Daily use follows the approved label.
Individual components
EPA, DHA, phospholipids, choline and astaxanthin require their own declared values and units where provided. Do not derive those quantities from oil mass or a research brochure.
Shell and allergens
The complete declaration includes the capsule shell and other ingredients. The crustacean source and the documented gelatin source must be considered in product assessment and labelling.
Research and the selected product
Research describes the preparation, dose and participants studied. It does not by itself establish the composition, recommended serving or effect of the finished Nordic Apothecary product.

The product sheet and the scientific reference section have different roles. Both should remain traceable to their own evidence.

03 / SCIENTIFIC CONTEXT

What has krill-oil research examined?

Published studies have investigated fatty-acid profiles, circulating choline during exercise and muscle function. The examples below describe research scope. Findings must be interpreted in relation to the study population, oil preparation and dose.

These studies concern particular krill-oil preparations, not the finished Nordic Apothecary product. Research doses are not recommendations for using our product.

Bibliographic references do not identify our supplier or mean that every study investigated the same ingredient.
