The Science of Complete Vitality

Complete daily multivitamin, fibre & probiotic formula.

The One is your all-in-one daily supplement designed to support energy, immunity, digestion, and vitality. Why take three different pills when you can get everything you need in one?

We designed The One to be the only supplement you need on your bathroom shelf, solving the problem of "pill fatigue" without compromising on quality. We have combined 17 essential vitamins and minerals with a high-fibre blend, live probiotics (1 billion CFU), and nutrient-dense botanicals like Alfalfa and Seagreens®. It is the ultimate foundation for your daily wellness routine.

Why Choose The One?

• Simplicity Solved: Combines the essential pillars of health—multivitamins, probiotics, and fibre—into a single, cost-effective capsule.
• Filling the "Nutrient Gap": Uses wild-harvested Seagreens® to provide trace minerals depleted from modern farmed soils.
• Better Absorption: A healthy gut absorbs nutrients better. Included live cultures and fibre prep your digestive system to actually utilise the vitamins you are taking.
• Gentle & Natural: Balanced with natural botanicals like Alfalfa to be gentle on the stomach, avoiding the nausea caused by synthetic mega-dose vitamins.

Total Wellness Matrix

We have grouped the 30+ active ingredients by their biological targets:

• Energy Metabolism: B-Complex Vitamins (B1, B2, B3, B5, B6, B12) and Iron act as co-factors in the mitochondria, converting food into cellular energy to reduce tiredness.
• Immune Defence: Vitamin C, Vitamin D3, Zinc, and Selenium support the production of white blood cells and protect them from oxidative stress during infections.
• Digestive Function: Psyllium Husk provides bulk to support intestinal transit, while Probiotics replenish the gut microbiome to crowd out bad bacteria.
• Structural Support: Biotin, Zinc, and Selenium are essential for the protein synthesis required to maintain normal hair, skin, and nails.

*Please see the product images for the full nutritional label and complete ingredient list.

How to Use

Take 1 capsule, 1 to 3 times per day with food and water.

Active Tip: Because this formula contains natural dietary fibre, it is important to drink plenty of water throughout the day to help the fibre move through your digestive system efficiently.
