Things You Might Be Wondering
Why should I take Vitamin D3 + K2 together?
Vitamin D3 helps your body absorb calcium, while Vitamin K2 directs that calcium into your bones instead of your arteries. Together, they support strong bones and healthy cardiovascular function more effectively than D3 alone.
What are the benefits of Vitamin D3 + K2?
Vitamin D3 + K2 supports bone strength, immune function, muscle health, and heart health. This combination is especially important for people with limited sun exposure or modern indoor lifestyles.
How much Vitamin D3 + K2 should I take daily?
Most adults benefit from 1,000–4,000 IU of Vitamin D3 and 90–200 µg of Vitamin K2 (MK-7) daily. Always follow the directions on the product label and consult your GP if unsure.
When is the best time to take Vitamin D3 + K2?
Vitamin D3 and K2 are fat-soluble, so they are best taken with a meal that contains healthy fats. Taking them with breakfast or your main meal improves absorption
Who should not take Vitamin D3 + K2?
People taking blood-thinning medication, those with kidney conditions, calcium disorders, or women who are pregnant or breastfeeding should consult a healthcare professional before use
What does MK-7 mean in Vitamin K2?
MK-7 is a highly bioavailable form of Vitamin K2 that stays active in the body for longer, providing consistent support with once-daily dosing.
Can I get enough Vitamin D3 + K2 from food and sunlight?
In the UK, it’s difficult to maintain optimal Vitamin D levels year-round due to limited sunlight. Vitamin K2 is also rare in modern diets, making supplementation a reliable option.
