Pros
- Dual nutrient formula (D3 + K2) for synergistic bone and heart benefits.
- Non-GMO, Soy Free, and Kosher certified for clean supplementation.
- GMP Quality Assured with in-house lab testing for purity and potency.
- Affordable price point for a two-month supply.
- Trusted brand with decades of experience in natural supplements.
Cons
- Some users may prefer higher vitamin D3 dosages (e.g., 2000 IU) for stronger immune support.
- Capsules are beige in color, which may indicate natural ingredients but could be less visually appealing.

The NOW Supplements Vitamin D-3 & K-2 combines 1000 IU of vitamin D3 with 45 mcg of vitamin K2 in a single veg capsule. 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.
The synergy between D3 and K2 is a standout feature. Vitamin D3 enhances calcium absorption, while K2 directs that calcium to the bones and teeth, preventing it from depositing in arteries. This combination supports both skeletal strength and heart health. The 1000 IU D3 dosage is suitable for general maintenance, and the 45 mcg K2 (as MK-7) ensures optimal bioavailability.
NOW is a reputable manufacturer with GMP Quality Assurance and third-party testing. The capsules are vegan, non-GMO, soy-free, and kosher. Each bottle contains 120 capsules, providing a two-month supply when taken as directed. The beige color reflects the natural ingredients, and the packaging is straightforward and informative.
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.
Buying Guide
Potency and Dosage
When choosing a Vitamin D3 supplement, the dosage matters for your individual needs. The NOW Supplements, Vitamin D-3 & K-2 provides 1,000 IU of D3 per capsule. This is a moderate dose suitable for daily maintenance. If you have a known deficiency, your healthcare provider may recommend a higher amount, but for general wellness, this level helps maintain healthy serum levels without going overboard.
Always consult with a professional before starting any new regimen. The balance of D3 and K2 in this product is designed to work together, which simplifies your supplement stack.
Added Vitamin K2 for Synergy
Vitamin D3 alone is great, but adding K2 enhances the benefits. Vitamin K2 helps direct calcium to your bones and teeth rather than allowing it to settle in soft tissues like arteries. This dual support is a key reason the NOW combination stands out. The product contains 45 mcg of K2 as menaquinone-7 (MK-7), a form that is well absorbed and long-lasting in the body.
