VeriMomIs ascophyllum nodosum/fucus vesiculosus/hizikia fusiforme/kjellmaniella gyrata/lessonia nigrescens/saccharina angustata/saccharina japonica/undaria pinnatifida extract safe during pregnancy?
This multi-species seaweed extract (mixture of brown algae/kelp extracts) has no harmonised reproductive classification (no H360/H361) and no CIR or SCCS safety assessment flagging reproductive toxicity; peer-reviewed literature notes that seaweeds can be a source of iodine (a potential endocrine concern) but topical cosmetic use generally gives low systemic exposure. Therefore hazard and mechanism scores default to 0; exposure is scored 1 (low but measurable) to reflect possible limited dermal uptake of soluble minerals such as iodine from topical products (CosIng; PubMed review of seaweed iodine).

Frequently asked questions
- Is ascophyllum nodosum/fucus vesiculosus/hizikia fusiforme/kjellmaniella gyrata/lessonia nigrescens/saccharina angustata/saccharina japonica/undaria pinnatifida extract safe during pregnancy?

- Is ascophyllum nodosum/fucus vesiculosus/hizikia fusiforme/kjellmaniella gyrata/lessonia nigrescens/saccharina angustata/saccharina japonica/undaria pinnatifida extract safe while breastfeeding?
- No regulatory harmonised classification or authoritative safety assessment identifies a reproductive/breastfeeding hazard for topical algal extracts. The main theoretical concern is iodine transfer to breast milk if systemic uptake occurred, but topical use is expected to produce low systemic levels; therefore hazard/mechanism are 0 and exposure is low (1).
- Is ascophyllum nodosum/fucus vesiculosus/hizikia fusiforme/kjellmaniella gyrata/lessonia nigrescens/saccharina angustata/saccharina japonica/undaria pinnatifida extract safe for baby skin?
- No evidence of developmental or reproductive toxicity from these seaweed extracts in regulatory sources. However, infant skin has higher absorption (and thyroid sensitivity to iodine), so exposure is increased by one category compared with adults (adult e=1 → infant e=2), reflecting low-to-moderate potential for increased percutaneous uptake of water-soluble minerals from topical application on 0–3 year skin.
