Vitamins K2 & D3
Verified purchase
My wife has been using vitamin K2 D3 for a while now, usually taking it once a day in the morning with breakfast as part of her daily routine. She started using it to support her overall health, especially since she prefers combining vitamin D3 with K2 in one supplement instead of taking them separately. What she likes most is the consistent quality — it feels like a reliable product she can trust and keep using long term. The tablets are a reasonable size, easy to take and don’t cause any discomfort when swallowed, which is important for her since she doesn’t like large pills.

Great supplement, I take 1 serving per day. The vitamins K2 and D3 work together. It supports healthy bone and heart function. Plus, it contains calcium. It is great overall. I highly recommend it.

for cardiovascular health and bone density
Verified purchase
I take this combination daily because Vitamin D3 is crucial for calcium absorption, while K2 ensures that calcium is properly directed to my bones and not soft tissues. It's a non-negotiable duo for my bone density and cardiovascular support. I feel reassured knowing I'm optimizing my mineral use.

Vitamin K2
Verified purchase
I like Source Naturals, I have high hopes for the purity and effectiveness of this product. However, please, I just want pure vitamin K2 with some Natto nutrients on the side. Since I can't find any Source Naturals product with pure vitamin K2, I will change to Thorne, after this product.

I started taking this Vitamin K2 + D3 supplement a few months ago after reading about how well these two vitamins work together, and I’m really happy with it so far. The tablets are small, easy to swallow, and don’t have any strong smell or aftertaste. I love that this formula combines Vitamin D3, which helps with calcium absorption and immune support, and Vitamin K2, which helps guide calcium to the bones instead of soft tissues — it’s a perfect balance for overall bone and heart health. Since I began using it regularly, I’ve noticed I feel more energetic and my joints don’t feel as stiff, especially during colder weather. It’s hard to tell the effects of supplements sometimes, but with this one I genuinely feel a difference. I also like that it supports healthy teeth and general well-being, not just bones. The packaging was secure and the tablets came fresh, just like everything else I’ve ordered from iHerb. The price is also very reasonable for the quality. It’s a simple but powerful supplement that fits easily into my daily routine. Overall, I would definitely recommend this product to anyone looking for a convenient way to support bone strength, heart health, and immunity — especially if you spend a lot of time indoors and don’t get much sun exposure. Good size, ingredients, and has a lot of benefits
