Alginic acid
Other names Algin, E400
Alginic acid: low in FODMAPs and nickel. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- FODMAPsLow
Alginic acid comes from brown seaweed and ferments in the colon - but slowly and evenly, without the fast osmotic pull that makes a FODMAP a FODMAP. Low rather than none, because it does feed the bacteria; low rather than high, because it does it gently and is used in fractions of a percent.
- NickelLow
Alginic acid is extracted from brown seaweed, and seaweed concentrates whatever the seawater carries. Extraction leaves most of it behind, which is why the level is low rather than the seaweed's own. Seaweed is the reason nickel is asked about here at all: it concentrates trace elements from seawater, and the review behind this level is about exactly that load in seaweed and in the ingredients made from it.

Frequently asked questions
Which intolerances does Alginic acid affect?
Alginic acid is notable for FODMAPs and nickel. Clear on lactose, histamine, gluten, fructose, oligosaccharides, sorbitol, sucrose, tyramine, salicylate and oxalates.
Does Alginic acid contain FODMAPs?
Alginic acid contains only low levels of FODMAPs. Alginic acid comes from brown seaweed and ferments in the colon - but slowly and evenly, without the fast osmotic pull that makes a FODMAP a FODMAP. Low rather than none, because it does feed the bacteria; low rather than high, because it does it gently and is used in fractions of a percent.
