Ingredients chosen for a formula you’ll love.
No synthetic additives or fillers just 100% plants, optimised for maximum absorption.
Vitamin D3 from Lichen (Cholecalciferol)
Vitamin D3 from Lichen (Cholecalciferol) is a plant-based form of the essential vitamin that supports bone health, immune function, and mood balance. It aids calcium absorption, promoting strong bones and overall vitality.
Vitamin K2 (all-trans MK-7)
Vitamin K2 (All-Trans MK-7) is a bioactive form of vitamin K that supports bone strength and cardiovascular health by guiding calcium to where it’s needed most.
Peppermint Essential Oil
Cinnamon extract is derived from the bark of cinnamon trees and has long been used in food and drink for its warm, aromatic flavour. It is a plant-based ingredient commonly used in natural formulations.
Steviol Glycosides
Steviol Glycosides are the natural sweet compounds extracted from stevia leaves, offering a calorie-free alternative to sugar. They provide sweetness without spiking blood sugar levels, making them ideal for supporting healthy weight management and glucose control.
Tea Saponin
Tea saponins are naturally present in tea leaves and have been used in food and beverage applications for generations. They are valued as plant-derived compounds commonly used in natural formulations.
Vitamin E (alpha-Tocopherol)
Vitamin E (Alpha-Tocopherol) is a powerful fat-soluble antioxidant that protects cells from oxidative damage, supporting skin health, immune function, and cardiovascular well-being.
More effective than all others
While standard Vitamin D supplements often come in hard-to-absorb tablet or capsule form — our experts have developed a fast-absorbing oral spray that delivers where it matters most.
