Why are Vitamins D, K and Iodine Important?
Vitamins D and K, together with iodine, are vital nutrients that contribute to the body’s core systems — bone strength, thyroid balance, cardiovascular function, and cognitive health. Vitamin D supports calcium absorption, immune balance, and mood regulation. Vitamin K aids in directing calcium into the bones while preventing buildup in the arteries. Iodine is essential for producing thyroid hormones, which regulate metabolism, energy, and brain function. Deficiencies in any of these nutrients can lead to hormonal imbalance, weakened bones, and poor cardiovascular and cognitive performance.

FAQs
Can I take this supplement with my multivitamin?
Yes, but ensure your multivitamin does not already contain high levels of vitamins D or K. Consult your healthcare provider for personalised guidance.
Why are both forms of vitamin K2 included?
MK-4 and MK-7 provide complementary benefits — MK-4 acts quickly in soft tissue, while MK-7 remains active longer in the bloodstream.
Is this product suitable for vegans?
This formula is gluten free and non-GMO but not vegan due to the source of vitamin D3 (cholecalciferol).
