I couldn't find it in my grocery store, so I ordered it here and am happy with my purchase!"

"After reading that Vitamin K could help with my tendency to bruise easily, I started taking this product. Previously, I would bruise from minimal impact, but after using it for almost a year, I hardly bruise at all. The only recent bruise was from a hard impact, which is a huge improvement. I highly recommend this product, but be patient; the results take time. This product is safe for two doses a day, unlike others that contain larger amounts of Vitamin K components."

"I bought these specifically for my mother, and she definitely recommends them! In the past, she tried other products but didn’t feel any difference. However, these vitamins really give her a boost!

“I found a very small opossum that had eaten rat poison in my backyard. His poop was bright blue, indicating he had ingested poison, and I rushed to get him treatment. Unfortunately, no vets or rehabbers were available. After researching, I learned the poison reduces K1 stores, preventing blood clotting. I called emergency vets for a prescription but they required an in-person visit with a 6+ hour wait. Instead, I ordered K1 via Prime and gave him a K2/K1 multi supplement in the meantime. After starting treatment, he felt better and I was extremely happy with this product because of its ease of use. If you’re looking for help with rat poison, I highly recommend this product. Order it now and search local stores for any available K1.”

“I take this vitamin K daily and I really enjoy it. It has a great taste and is easy to dissolve in my mouth before swallowing. Overall, it's a fantastic product.”

“While I appreciate the product, my main issue is that it's quite sweet. It’s fine for adults, but I wouldn’t recommend it for newborns. When I dissolved some in milk for my baby, she reacted strongly, seeming flushed and cranky for hours. It was like giving her sugar directly. I later discovered Thorne liquid drops, which are much better for little ones.”

"I needed a vitamin D3 supplement with clean ingredients that has no taste. This product is easy to swallow and I keep it in the fridge for best results."

"I've experienced extreme effectiveness with this product. It absorbs nutrients quickly into my body and I use it alongside D3 for added benefits. I'm grateful to have found this product."

"After taking this product, I've noticed a positive change in my teeth. It's been a great addition to my routine!"
