Huel Powder does not contain whole leguminous plants. While natural peas can be high in histamine, Huel uses pea protein isolate, which removes most compounds, including histamine.
If your pea allergy is histamine-related, note that Huel may contain histamine liberators or diamine oxidase enzyme blockers, which could trigger symptoms in people with histamine intolerance. Individual reactions vary.
If your pea allergy is linked to another component of peas, we strongly recommend consulting your doctor before consuming Huel.
