Sea fibre-cal

I have osteoporosis and find it incredibly difficult to get enough calcium from my diet. I use Seafibre-cal on the days that I fall short of my 1300mg.

Frequently Asked Questions

Straight answers to what everyone wants to know before trying seaweed-based health products.

What does seaweed actually do for the body?

Seaweed is a natural powerhouse of prebiotics, antioxidants, and minerals. It supports gut health, improves skin clarity, boosts immunity, and helps your body function at its best — all from one ingredient.

Are your products safe to use long-term?

Yes. All our products are made from food-grade, sustainably harvested seaweed and formulated to be safe for daily, long-term use.

Can I use this with other supplements or medications?

Generally, yes — our formulas are designed to complement most wellness routines. But if you’re on specific medications, we recommend checking with your healthcare provider.

Where is your seaweed sourced from?

Our seaweed is grown and harvested right here in Australia, using sustainable aquaculture practices. It’s 100% traceable, clean, and nutrient-rich.
