Detailed Review
The NutraOptimum Vitamin D3+K2 Premium Supplement stands out in the crowded vitamin market by offering a science-backed formula that combines two essential nutrients that work synergistically for optimal health benefits.
Vitamin D3 (cholecalciferol) is the more bioavailable form of vitamin D that your body naturally produces when exposed to sunlight. With 5000 IU per serving, this supplement provides 625% of the Daily Value, making it ideal for those with deficiencies or limited sun exposure.
What makes this formula special is the addition of 100mcg of vitamin K2 in the form of MK-7 (menaquinone-7). K2 works alongside D3 to ensure calcium is directed to your bones rather than accumulating in arteries and soft tissues. The MK-7 form is particularly valuable as it remains active in the body longer than other forms of vitamin K.
During our testing, we were impressed by the quality control standards. Each batch is third-party tested for purity and potency, with certificates of analysis available upon request. The non-GMO ingredients are sourced from reputable suppliers, although we do wish the product was suitable for vegetarians.
Value-wise, with 90 capsules per bottle (a 3-month supply at the recommended dosage), the price point of $24.99 represents good value despite being slightly higher than basic vitamin D supplements without K2.
For those concerned about vitamin D deficiency or looking to support bone health, cardiovascular function, and immune support, this supplement provides an excellent combination of essential nutrients in their optimal forms.
