Description

YouNutri Vitamin D3 & K2 4000IU / 100µg is a high-strength, one-tablet-a-day formula that pairs two essential nutrients working in perfect synergy to keep your bones strong, your immune system resilient, and your arteries clear.

Each tablet provides 4000IU (100µg) of Vitamin D3 and 100µg of Vitamin K2 (MK-7) to support bone, immune, and cardiovascular health.

The NHS recommends daily vitamin D supplementation between October and March, or year-round if you have limited sunlight exposure — making this combination ideal for ongoing support. Including K2 ensures calcium is used safely and effectively.


 🌞 Vitamin D3 helps your body absorb calcium and phosphorus, supporting bone and muscle health while contributing to immune system function.


❤️ Vitamin K2 complements D3 by activating proteins that transport calcium to where it’s needed — into bones and teeth — and away from where it isn’t: arteries and soft tissues.

Together, they maintain both skeletal strength and cardiovascular integrity.


YouNutri products are manufactured in the UK under GMP standards and independently lab-tested for purity and potency.
Each pack delivers 365 vegetarian, gluten-free tablets — 12 months supply — providing outstanding value and reliability.

Supported by our 60-day money-back guarantee, this advanced D3 + K2 complex is your complete year-round support for bones, immunity, and arterial health.

💡 Why YouNutri Vitamin D3 & K2 Works

Focus on the science behind strong bones, immunity, and arterial healthTrue health isn’t about taking more — it’s about balance.
YouNutri’s Vitamin D3 & K2 formula combines two essential nutrients that work together to ensure calcium goes exactly where it should: into your bones and teeth, not your arteries.

🌞Vitamin D3 — The Sunshine Nutrient for Strong Bones & Immunity

Vitamin D3 (cholecalciferol) is the form your body naturally produces when exposed to sunlight.It helps absorb calcium and phosphorus — key minerals for maintaining bone density, muscle strength, and immune function.The NHS recommends supplementation during the darker months (October–March) or year-round if you get limited sun exposure.Studies show optimal D3 intake supports immune defence, muscle performance, and even mood regulation — making it a foundation nutrient for overall vitality.

❤️Vitamin K2 (MK-7) — Directing Calcium Where It Belongs

Vitamin K2 activates proteins like osteocalcin and matrix GLA protein, which guide calcium into bones and teeth and keep it out of soft tissues.This prevents calcium from building up in arteries — supporting long-term cardiovascular health and flexible, healthy blood vessels.The MK-7 form used in YouNutri’s formula is the most bioactive and long-lasting, meaning it stays in the body longer for consistent benefit.Studies link K2 supplementation to improved bone strength and reduced arterial calcification when taken alongside D3.

⚖️The D3 + K2 Synergy — Safe, Effective, and Complete

Many high-dose vitamin D supplements raise calcium absorption but lack K2, which can lead to calcium imbalance.YouNutri’s balanced pairing ensures calcium is properly metabolised and directed to where it’s most beneficial.Research shows D3 and K2 work synergistically — each enhances the other’s function, creating a safe and effective formula for daily use.This intelligent combination supports bone, immune, and arterial health simultaneously.

🧬Balanced Strength — Not Excess

Each tablet provides 4000 IU (100µg) of Vitamin D3 and 100µg of Vitamin K2 (MK-7) — a ratio supported by clinical research for both safety and efficacy.The average UK adult gets very little vitamin D from food alone, especially during winter.Many competitor products offer extremely high D3 doses (5000–10,000 IU) without K2, which may lead to calcium imbalance or reduced long-term effectiveness.YouNutri’s carefully calibrated dosage provides full benefits while respecting the body’s natural balance — effective, not excessive.

🔬The Result — Total Body Balance

By supporting the natural flow of calcium through the body, YouNutri Vitamin D3 & K2 helps maintain:

• Strong, resilient bones and teeth
• A robust immune system
• Flexible, healthy arteries
• Steady energy and vitality all year round

FAQs

Vitamin D3 boosts calcium absorption, while Vitamin K2 (MK-7) ensures calcium is used correctly — building bones instead of depositing in arteries.
Together, they promote optimal bone density and cardiovascular protection.

Yes. The UK Food Standards Agency (FSA) recognises up to 4000 IU (100 µg) per day as a safe upper limit for healthy adults, supporting optimal vitamin D levels year-round.

Yes — D3 increases calcium absorption, but without K2, calcium can accumulate in arteries.
K2 (MK-7) helps guide calcium safely into bones

Take one tablet daily with food, ideally with your main meal, since both vitamins are fat-soluble and absorb best alongside dietary fats.
