Vietnam has a long history with algae as food — seaweed has been part of coastal Vietnamese cooking for centuries — but spirulina cultivation is relatively new, having expanded rapidly from around 2010 as awareness of its nutritional benefits spread through Vietnamese health communities. The Da Nang operation was established in 2016 by a small agricultural cooperative working with technical support from a Vietnamese university agronomy programme.
Da Nang's climate is near-ideal for spirulina: intense year-round sun, warm temperatures (average 28–32°C during production months), and low altitude. The facility uses open raceway ponds fed by borehole water, which is tested regularly for contamination. The main environmental challenge is the typhoon season (August–October), which forces production to pause or scale back as strong winds can introduce debris into open ponds.
The market for this producer is almost entirely domestic — Vietnamese consumers in Da Nang and the surrounding central coastal region, plus some supply to Ho Chi Minh City distributors. They sell dried powder and fresh paste, with the fresh paste particularly popular in local markets where consumers appreciate the brighter colour and cleaner taste.
Quality infrastructure is developing but not yet at the international export standard of Indian or Taiwanese producers. The cooperative does regular in-house testing and has begun working with an external accredited laboratory for annual certification — a step toward eventually reaching export markets in Singapore and beyond.
The cooperative's approach to nutrition is noteworthy: they work directly with local health clinics to supply spirulina for nutritional supplementation programmes targeting anaemia in pregnant women and young children. This practical application of spirulina's documented iron bioavailability keeps their production focused on real nutritional outcomes rather than purely commercial supplementation.
