Key Benefits

  • Provides 3000 IU per spray to support optimal vitamin D levels.

  • Promotes bone, muscle, and immune health.

  • Delivers vitamin D directly through the mouth to maximise absorption.

Vitamin D, often referred to as the sunshine vitamin, plays a crucial role in various bodily functions. It helps maintain healthy bones and teeth by supporting calcium absorption, aids in muscle function, strengthens the immune system, and promotes general wellbeing. Vitamin D comes in two forms: D2 and D3. While both are usable by the body, vitamin D3 is naturally occurring, the most active, and preferred for supplementation.

BetterYou's vitamin D oral spray delivers 3000 IU (75μg) of vitamin D3 per dose, providing the ideal strength for adults, especially those in regions with limited sunlight exposure. The formula uses micro-sized droplets that are absorbed through the soft tissues of the mouth, allowing the vitamin D to enter the bloodstream quickly and efficiently, bypassing the digestive system for optimal absorption.

Perfect for anyone needing to maintain optimal vitamin D levels, this easy-to-use, peppermint-flavoured spray is an effective solution for supporting overall health.

What sets BetterYou apart is their commitment to superior, science-backed delivery methods, making supplementation easier and more effective to fully benefit the body. Their range of Vitamin D Oral Sprays is designed to deliver vitamin D directly into the mouth, leveraging the soft, absorbent tissue and rich vein system for optimal absorption. This innovative approach makes the mouth an ideal gateway for nutritional intake. With various dosage strengths to suit all ages, their award-winning collection offers a pioneering, convenient alternative to traditional vitamin D supplements.

BetterYou empowers individuals to enhance their wellbeing through informed choices and innovative science, while also promoting sustainability to support both the environment and communities. Having won the Queen’s Award for Enterprise, the brand leads in nutritional innovation with its award-winning, pill-free supplements that overcome the limitations of traditional tablets and capsules. Scientifically formulated for maximum nutrient absorption and efficacy, these supplements are developed in collaboration with Cardiff University's Pharmacy and Pharmacology Research Team. Backed by leading scientists, they provide evidence-based solutions for optimal health.
