Question 1

Is the 100 mcg dosage in this product strong enough to be effective?**

Accepted Answer

For most people following general health guidelines, 100 mcg of Vitamin K2 (MK-7) is a solid and effective daily dose. Many of our customers successfully use it as part of their wellness routine. However, some individuals with specific, high-dose requirements—often discussed in biohacker communities—opt for 200 mcg alternatives. As always, we recommend consulting with a healthcare professional to determine the right dosage for your personal health goals.

Question 2

How long should I take this before expecting to see benefits, and do I need to take it with Vitamin D3?**

Accepted Answer

Vitamin K2 works on a cellular level, so it's not a supplement you "feel" immediately. Most users report taking it consistently for 3-6 months before noting benefits in follow-up lab work related to calcium metabolism. Taking it with Vitamin D3 is highly recommended, as they work synergistically. In fact, a common sentiment in reviews is that this product is the "perfect partner" for D3, helping direct calcium to your bones and teeth instead of your arteries.

Question 3

I've seen comments about softgels being stuck together or having a smell. Is this normal?**

Accepted Answer

On rare occasions, softgels can stick together due to temperature fluctuations during shipping, but this doesn't affect the quality or potency of the vitamin inside. A mild, natural odor from the softgel material or the oil-based MK-7 is also possible. However, if you receive a bottle where many capsules are fused or there's a strong, rancid smell, this could indicate a storage issue. In such cases, please contact our customer service immediately for a replacement or refund—we stand by our product quality.

Question 4

Is this suitable for someone on blood thinners like Warfarin (Coumadin)?**

Accepted Answer

**No, it is not.** Vitamin K can interfere with the action of certain blood-thinning medications. If you are on anticoagulant therapy (e.g., Warfarin), it is **critically important** to consult your doctor before considering any Vitamin K2 supplement. Your physician can monitor your INR levels and advise if, and how, you can safely incorporate it.

Question 5

What makes Nutricost K2 a good value compared to other brands?**

Accepted Answer

Our customers consistently highlight the exceptional value. You're getting a pure, gluten-free, and non-GMO MK-7 in easy-to-swallow softgels at a cost-per-serving that's often lower than many competing brands. While some alternatives offer higher single doses or patented forms at a premium, this product provides a trusted, effective foundation for daily K2 supplementation, especially when paired with D3—which is exactly how most of our 5,800+ reviewers use it.
