Sea moss has become one of the trendiest “superfoods” on social media.
You see claims about 92 minerals including iodine, calcium, magnesium, zinc, iron, potassium, and a long list of other nutrients.
So you throw some into your smoothie every morning and figure you’re covering your mineral bases. Not so fast.
Sea moss gives you a messy mixture of minerals in a variable food matrix. And one of the biggest things in that matrix is carrageenan.
Carrageenan gives sea moss its thick, slippery texture. Food companies also extract carrageenan from red seaweed and use it as a thickener and stabilizer. Pick up almost any nut or oat milk on the shelf and you’ll see it in the ingredients. Carrageenan has a big problem.
It can inflame your gut.
In a 2026 trial, healthy adults who consumed carrageenan for four weeks developed a leakier gut barrier. In a separate study, carrageenan triggered inflammatory responses in human intestinal tissue, including increases in inflammatory cytokines.
Okay, but what about the minerals? Well….
The 92-Mineral Claim Sounds Better Than It Is
Your body needs minerals for almost everything including energy production, thyroid function, hormones, bones, muscles, and nerves. Hundreds of enzymes depend on them.
That makes minerals an important part of any longevity strategy. But you need minerals in the right forms and amounts. Sea moss gives you neither.
The mineral content varies with the species, growing conditions, water, processing, and storage. Iodine varies so much that many sea moss products don’t even tell you how much you’re getting. Even if the sea moss you purchased happened to have higher mineral content, your body likely wouldn’t get much of those minerals, due to plant compounds that bind them and prevent you from absorbing them.
You need minerals your body can use.
Sea moss is starting to look pretty weak. But wait until you look at what researchers recently found in commercial sea moss products.
