THORNE to SUPPORT D3!!!
I am VERY glad to have this product to supplement my vitamin D3. I think the D3 will work much better with the ingredients included in this Thorne product! I usually can get pills down my throat easily! But I am 74 now so maybe I need to wash it down with more water. I still kind of have a pill sensation in my throat, but I can breathe just fine so I’m going to keep taking the pills … and perhaps start with a bigger gulp of water to wash each pill down!! This problem is probably with me and not the product!! And actually as I am writing this, the lump in my throat sensation has been resolved!!

This is my second time purchasing THORNE’s Vitamin K, and I’m really happy with the quality. I trust Thorne as a brand, and this supplement feels like it’s making a difference in my overall health. The capsules are easy to take, and I like that the formula includes a balanced mix of K1 and K2. Definitely sticking with this one!

High quality product definitely recommend!
Why did you pick this product vs others?: I've been using Thorne K Vitamin alongside my Vitamin D supplement, and I couldn't be happier with the results. The quality of this product is top-notch, which is exactly what I expect from Thorne. It’s been a great addition to my daily routine, and I really appreciate that it complements my Vitamin D to maximize absorption and effectiveness. I’ve noticed a positive difference in my overall health since incorporating it, and I feel more energized. If you're looking for a reliable Vitamin K supplement, I definitely recommend giving Thorne a try. You can trust the quality and feel confident in your purchase!
