92 Minerals.
One Ingredient.
92
Sea moss contains 92 out of 102 minerals found in the human body — iodine, calcium, magnesium, iron, zinc, and more. In a single whole-food ingredient.
Rich in Essential Minerals
Iodine, calcium, magnesium, potassium, and iron — 92 bioavailable minerals that support energy, immunity, and cellular health at every age.
Gut Health & Digestion
Sea moss acts as a natural prebiotic, feeding beneficial gut bacteria and providing soluble fibre that supports a healthy, balanced microbiome.
Certified & Verified Pure
Tanzania's only certified seaweed-for-food brand — meeting strict food safety standards with a fully traceable supply chain from ocean to jar.
Thyroid & Hormone Support
Natural iodine from sea moss is one of the most bioavailable sources for thyroid hormone production and metabolic function.
Ocean-Positive Farming
Seaweed farming sequesters CO₂, oxygenates the ocean, provides habitat for marine life, and requires zero land, freshwater, or fertiliser.
Women-Led Supply Chain
88% of our farming network are women. Purchasing Healthy Seaweed Cafe products directly increases incomes for women-led households in Zanzibar.
Our Provenance
From East Africa's Oldest Seaweed Coast
Zanzibar has been one of Africa's primary seaweed-producing coastlines since 1990. With 25,000 farmers and 11,000 tonnes of annual production, it is the world's largest concentration of women seaweed farmers — and the source of every product Healthy Seaweed Cafe makes.
This is not ocean-positive branding. It is a verified, certified, community-anchored supply chain operating at the precise intersection of blue economy development and women's economic empowerment.
Only certified seaweed-for-food brand in Tanzania — no imitators
252 active farming families; target 1,000 by 2030
88% of farmers are women — income increase from $30 to $300/month projected

The Environmental Case
Every Purchase Is an Ocean Act.
Seaweed farming doesn't just avoid harm — it actively repairs the ocean. Here is what the Healthy Seaweed Cafe supply chain delivers every year.
460t
CO₂ Sequestered Annually
Across 8 hectares of active seaweed cultivation — equivalent to planting 21,000 trees per year.
8ha
Sustainable Ocean Cultivation
Zero land use. Zero freshwater. Zero fertiliser. Seaweed farming is the lowest-impact food production method on Earth.
88%
Women in the Supply Chain
One of the highest rates of women's participation in any food supply chain globally. Environmental impact + gender equity, built in.
"Seaweed requires no land, no fresh water, no fertiliser, and no pesticides. It oxygenates the water, provides marine habitat, and removes carbon from the ocean. The supply chain behind every Healthy Seaweed Cafe product is ocean-positive by design."
