Product Description

Most traditional vitamin D pills pass through your digestive system without ever being fully absorbed, Welzo Ultra Purity Liposomal Vitamin D3 + K2 MK-7 uses liposomal technology to enhance absorption.

Taking Vitamin D3 alone increases calcium absorption, but without Vitamin K2, that calcium can deposit in your arteries instead of your bones. Welzo combines bioidentical Vitamin D3 with long-acting Vitamin K2 (MK-7) to create the ultimate synergistic formula: D3 absorbs the calcium, and K2 directs it straight to your bones and teeth—where you need it most.

Key Benefits

⚡ Up to 5x Higher Absorption: Advanced liposomal technology bypasses digestive breakdown, ensuring maximum bioavailability and faster cellular uptake.
🦴 Complete Bone & Dental Matrix Support: Vitamin D3 promotes calcium uptake, while Vitamin K2 activates osteocalcin to bind calcium directly into bone tissue.
❤️ Arterial & Cardiovascular Protection: Vitamin K2 (as premium MK-7) activates Matrix Gla Protein (MGP), preventing calcium accumulation in soft tissues and blood vessels.
🛡️ Year-Round Immune & Energy Boost: Keeps your immune defenses robust and supports daily mood stability, especially during low-sunlight months.
💧 Precision Liquid Dropper: No massive capsules or pill fatigue. Customize your exact daily dosage with our clean, taste-neutral liquid drops.
🌿 Ultra-Pure & Clean Standard: Formulated without artificial fillers, synthetic colors, gluten, dairy, soy, or harsh chemical additives.

How to use

Take the recommended number of drops shown on the bottle label, using the supplied dropper to measure your serving carefully. Count individual drops—a drop is not a full dropper.

Follow the labelled frequency and do not exceed the recommended daily intake. If you already take vitamin D in another supplement, include this when checking your total intake.

If you take warfarin or another vitamin K antagonist, consult your prescriber before use. If pregnant, breastfeeding, taking medication or managing a medical condition, seek advice from a healthcare professional.

Please consult the product packaging for accurate instructions on how to use the product.
