Vitality for the next chapter of life.
The subtle shift.
Somewhere in your forties, the body changes its rhythm. A collection of subtle shifts that, together, feel like a new version of normal.
Energy that fades early
The afternoon dip lingers, and a good night's sleep doesn't quite top you back up.
Slower to recover
A reformer class, a full weekend, and your body takes a day longer to feel itself again.
Hormones finding balance
You're noticing shifts in mood, temperature, sleep and metabolism.
Not quite yourself
You're embracing this chapter. You'd just love to feel fully like you again.
It's time to be proactive.
The kindest thing you can do for your future self is to support your body early and consistently. We don't believe in "anti-ageing", we believe in being proactive about your health and nourishing your body through change.
You might not have heard of fucoidan.
It's been our family's quiet secret to vitality for generations. Fucoidan is a powerful bioactive compound naturally occuring in certain brown seaweeds. In nature, fucoidan exists to shield the plant from pathogens and enivornmental stress in the ocean. Research suggests those same protective properties may extend to human health.
Today it is one of the most studied marine compounds in the world: backed by over 4,000 scientific studies exploring its role in immunity, gut health and overall wellbeing. SeaQuo exists to bring this remarkable ingredient out of the science journals and into your daily routine.
The daily ritual of the world's longest-living people.
Okinawa, Japan is one of the world's five "Blue Zones". These are rare places where people live longer, healthier, more independent lives than almost anywhere else on earth.
Years old
Okinawa is known not just for long lives, but healthy ones. Its centenarians are famous for staying active, sharp and independent well into old age.
From brown seaweed
For centuries, brown seaweed has been an everyday staple of the traditional Okinawan diet.
A powerful marine compound
Brown seaweed is the natural source of fucoidan. It's thought to be a contributor to the Okinawans' exceptional health and longevity.
SeaQuo brings centuries of Okinawan wisdom into a simple daily ritual.
Support your thyroid, naturally.
Your thyroid regulates your metabolism, your temperature and the energy you feel each day.
It needs iodine to produce its hormones, T3 and T4. Seaweed is one of nature's richest sources of iodine.
- Naturally bioavailable iodine to support thyroid hormone production.
- Helps maintain adequate iodine intake, which can be low in modern diets.
Tested and transparent. SeaQuo Immune contains a tested, balanced amount of iodine (36mcg per capsule). If you have a thyroid condition or take thyroid medication, please speak with your healthcare practitioner before starting any seaweed supplement.
Vitality is a whole-body story.
Your body works as one connected system. Energy, immunity, gut and skin all influence one another. Rather than targeting a single area, fucoidan works throughout the body.
Energy
Supports steady daily energy that helps you feel like yourself from morning to evening.
Immune resilience
Fucoidan is studied for its immune-modulating properties, supporting a balanced immune response.
Gut balance
Helps maintain a healthy gut environment by promoting gut microbiota health and relieving inflammation.
Glowing skin
Supports skin hydration, elasticity and collagen health. A natural glow that reflects how well you feel within.
Uniting nature’s intelligence with scientific rigour.
SeaQuo® Immune combines certified organic Undaria pinnatifida seaweed with vitamin C and zinc. Two daily capsules, backed by science to support whole-body wellbeing.
Undaria pinnatifida (fucoidan)
A unique seaweed wholefood powder, rich in fucoidan – a powerful bioactive compound that supports immune balance, the gut microbiome and cellular defence. Fucoidan is backed by studies highlighting its antioxidant, anti-inflammatory and immune-modulating properties.
Vitamin C
A potent antioxidant that supports immune defence and the formation of collagen for skin health and repair.
Zinc
An essential mineral that supports gut lining integrity, skin health and a resilient immune system.
Hand-harvested from some of the most pristine waters on earth.
It begins in the cold, clean waters of Tasmania, where our fucoidan-rich Undaria pinnatifida naturally thrives. The seaweed is carefully foraged by hand from the wild coasts. It is then air-dried and finely milled into a powder, before being rigorously tested for purity and potency.
SeaQuo® Immune uses the seaweed spore, as this part of the plant contains the highest concentration of fucoidan in its untouched form, together with its wide array of naturally occurring nutrients.

Hi, we're Sara & Olivia, the mother-daughter duo behind SeaQuo.
The SeaQuo story began decades ago in Tasmania, with a family discovery of fucoidan’s extraordinary potential. This remarkable seaweed compound, found right on our doorstep, ignited a passion for sharing its benefits with the world.
High-quality fucoidan requires pure waters, careful harvesting and specialised extraction methods, making it far less accessible than many other wellness ingredients.
SeaQuo was born with a simple mission: to make the benefits of fucoidan accessible to more people. Using organic seaweed, wild-sourced from pristine waters and naturally rich in fucoidan, SeaQuo brings this powerful marine ingredient into an easy daily ritual.
