NutriFlair Vitamins D3 (5000 IU) + K2 (as MK-7) - Plant-Based with BioPerine, 90 Capsules

Looking for a supplement that combines two vital nutrients for your daily routine? NutriFlair’s plant-based formula delivers 5000 IU of vitamin D3 sourced from lichen and 100 mcg of vitamin K2 (as MK-7) from chickpeas. With added BioPerine black pepper extract to boost absorption, this synergistic blend is designed to help maintain normal bones and immune function, while contributing to normal blood coagulation.*

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are made equal. The form of vitamin K2 matters: MK-7 (menaquinone-7) has a longer half-life than MK-4, meaning it remains active in the body longer and can be taken once daily. NutriFlair uses MK-7 sourced from chickpeas. The vitamin D3 comes from lichen, making this supplement entirely plant-based and vegan-friendly. Each capsule provides 5000 IU of D3 and 100 mcg of K2—a well-studied ratio. The addition of BioPerine (black pepper fruit extract) has been shown to enhance the bioavailability of nutrients. Plus, the product is non-GMO, gluten-free, soya-free, and dairy-free, manufactured in a GMP-certified facility and third-party tested for quality and potency.*

Key Health Benefits

• Bone Health: Vitamin D3 contributes to normal calcium absorption, and vitamin K2 contributes to the maintenance of normal bones. Together they play a role in keeping your skeleton strong.*
• Immune Support: Vitamin D3 contributes to the normal function of the immune system, helping your body maintain its natural defences.*
• Heart Health: Vitamin K2 contributes to normal blood coagulation, which is important for cardiovascular function.*
• Dental Health: Proper calcium utilisation supports strong teeth and healthy gums.*

Why Take Vitamin D3 and K2 Together?

Vitamin D3 helps your body absorb calcium from the foods you eat. But without vitamin K2, that calcium may end up in soft tissues like arteries instead of where it belongs—your bones and teeth. Vitamin K2 activates proteins that direct calcium to the skeleton and help keep arteries flexible. Taking them together creates a synergistic effect that optimises the benefits of each nutrient. That's why many experts recommend a combined D3 + K2 supplement for comprehensive support of bone and cardiovascular health.*

Understanding the Synergy: How D3 and K2 Work Together

Once vitamin D3 is converted to its active form in the body, it increases the production of calcium-binding proteins in the intestine, enhancing calcium absorption. Vitamin K2 then steps in to activate matrix GLA protein (MGP) and osteocalcin. MGP inhibits calcium deposition in blood vessels, while osteocalcin incorporates calcium into the bone matrix. This coordinated action helps maintain healthy calcium balance: D3 brings calcium in, and K2 ensures it is used appropriately. Without adequate K2, the calcium absorbed thanks to D3 may not be properly utilised.*
