Product Description
The Smarter Way to Support Your Bones, Immunity & Everyday Wellness
Getting enough Vitamin D isn't always easy.
With modern indoor lifestyles, limited sunlight and changing seasons, many people struggle to maintain optimal Vitamin D levels throughout the year. Yet Vitamin D is one of the most important nutrients for supporting your overall health.
The difference is choosing a formula that works with your body—not just one that delivers a high dose.
That's why we created Welzo Ultra Purity Vitamin D3 + K2 MK-7 Liquid Drops.
Combining premium Vitamin D3 with highly bioavailable Vitamin K2 MK-7 in a smooth MCT oil base, this advanced formula is designed to maximise absorption while providing targeted nutritional support for your bones, muscles and immune system.
Small drops. Powerful daily support.
Why Vitamin D3 & K2 Together?
Vitamin D3 and Vitamin K2 work in harmony.
Vitamin D3 supports the absorption of calcium, while Vitamin K2 helps direct that calcium to where it's needed most—your bones and teeth.
Together they provide a more complete approach than Vitamin D alone.
Why Choose Welzo Ultra Purity?
High Potency Formula
Each full serving delivers:
✔ 100mcg (4000 IU) Vitamin D3
✔ 45mcg Vitamin K2 MK-7
Designed to provide premium daily nutritional support.
Premium MCT Oil Base
Unlike many tablets and capsules, our liquid drops are suspended in premium coconut-derived MCT oil to support excellent absorption and effortless daily use.
Simply place the drops directly into your mouth or mix into food or drinks.
No large tablets.
No difficult capsules.
Just convenient daily nutrition.
