Résumé

Ascophyllum nodosum is a brown seaweed containing bioactive compounds such as phlorotannins and fucoidans with demonstrated antioxidant, antiviral, and anti-inflammatory properties [PMID:37446599, 39772226, 34940701].

Contexte

Ascophyllum nodosum, also known as knotted wrack or bladderwrack, is a brown seaweed common in Arctic tidal waters [PMID:38276650, 30000910]. It is used as a source of nutraceuticals, functional animal feed, and agricultural biostimulants [PMID:32932674, 40863639, 31191576].

Composés actifs

The herb contains soluble fiber (alginic acid), vitamin B12, iron, iodine [PMID:30000910], phlorotannins (polyphenols) [PMID:37446599, 36364926], fucoidans (sulfated polysaccharides) [PMID:34940701, 37011755], and carotenoids such as fucoxanthin [PMID:30823356].

Mécanisme d'action

Phlorotannins exhibit antioxidant and antidiabetic properties by inhibiting digestive enzymes [PMID:37446599]. Enriched seaweed extract (ESE) inhibits influenza infection by interacting directly with virions to reduce virus-cell binding and inhibiting early and late stages of the influenza A lifecycle [PMID:39772226]. Fucoidans inhibit inflammatory processes via selectin blockade and enzyme inhibition [PMID:34940701].

Preuves cliniques

Preuve DInfluenza A Infection

Enriched seaweed extract (ESE) resulted in the complete inhibition of infection in plaque reduction assays and reduced virus-cell binding by 79.3% [PMID:39772226]

Preuve DMetabolic Syndrome/Hyperlipidemia

Phlorotannin-rich extracts significantly lowered serum fasting blood sugar, AST, ALT, total cholesterol, triacylglyceride, and free fatty acids in HED-induced hyperlipidemia rats [PMID:36364926]

Preuve CVeterinary Oral Health (Dogs/Cats)

Oral administration of A. nodosum reduces calculus and plaque accumulation, with powder form showing the strongest preventive action [PMID:37727971]

Preuve CSensitive Skin

Clinical evidence supports the use of A. nodosum extract in facial cosmetics for sensitive skin [PMID:34436303]

Preuve CMetabolic Syndrome (Humans)

Evidence base relies mainly on cell line and small animal models, with few human studies to date [PMID:33573121]

Sécurité et effets indésirables

A. nodosum can contain heavy metals such as arsenic, cadmium, and lead [PMID:30000910].

Grossesse et allaitement

Some sources recommend against use during breastfeeding due to high iodine content and potential heavy metal contamination; iodine is actively transported into breastmilk [PMID:30000910].

Synthèse des preuves

The evidence is primarily based on in vitro studies, animal models (rats, C. elegans), and veterinary reviews. Human clinical evidence is limited, particularly regarding metabolic syndrome, though some evidence exists for cosmetic use and veterinary dental health.
