This formula is designed for adults seeking comprehensive support for bone density, cardiovascular function, and immune health. It's an excellent choice for those who prefer a dual-nutrient supplement over taking separate pills.

One potential drawback is the relatively modest vitamin D3 dose of 1000 IU. Some individuals, especially those with deficiencies or limited sun exposure, may require a higher dosage. Additionally, the lack of customer reviews makes it harder to gauge long-term satisfaction. However, NOW's longstanding reputation mitigates this concern.
Overall, the NOW Vitamin D-3 & K-2 supplement offers a well-researched, high-quality combination at an affordable price. It's ideal for anyone looking to support bone and cardiovascular health with a clean, trusted brand. While the D3 dose may be low for some, it's a solid starting point for daily maintenance.

Frequently Asked Questions
What is the difference between vitamin D3 and D2?
Vitamin D3 (cholecalciferol) is the form produced by your skin from sunlight. Vitamin D2 (ergocalciferol) comes from plant sources. D3 is generally considered more effective at raising and maintaining blood levels of vitamin D.
Why combine vitamin D3 with K2?
Vitamin D3 increases calcium absorption, while vitamin K2 helps direct that calcium to bones and teeth instead of arteries. Together they support bone density and cardiovascular health. This synergy makes the combination popular among health conscious individuals in 2026.
How many capsules should I take per day?
The recommended serving is one capsule daily. Each capsule provides 1,000 IU of D3 and 45 mcg of K2. Always follow the label and consult your healthcare provider for personalized advice.
Is this supplement suitable for vegans?
The capsules are vegetable based and the product is labeled as Kosher and Non-GMO. However, vitamin D3 is typically derived from lanolin (sheep wool), so it may not be considered vegan. If you need a plant based alternative, look for vitamin D2 or vegan D3 from lichen.
