    I have no way to review the product but I received it almost immediately which was much appreciated as the baby came soon after.

    Great customer service!

    We ordered our vitamin K over the weekend and realized wow, this baby is coming soon...maybe before this will arrive. We should have done rush shipping. I contacted the company Monday morning and asked if we could upgrade to next day shipping and heard back from them really quickly. They made the change and our order just arrived (Tuesday at noon MST) so we feel much more prepared for baby’s arrival. I’m super impressed with the customer service. Thanks so much!

    Awesome product just as described

    The vitamin K is just as described. Easy to use and the label is easy to read. Took this to the hospital for my sons birth and the hospital pharmacy was able to do the dosing and made it very simple for me. I used it with my son in 2019 as well and had a great experience then as well which is why I ordered again and if I have any more kids I would definitely order again. Great company, great products.

    Much better than the one I bought off Amazon for my infant! Its concentrated and is easy to determine the dose and give. She also doesn't mind it unlike the other one and may even like it. She's 2 months old and breastfed.

    Super fast delivery

    Posted by Maria on 9th Sep 2020

    I haven't used it yet, it's going to be used for my newborn son, so I can't comment on the quality of the product obviously. But it came from the US to Greece impressively fast and in a great condition. Thank you!

    K without the black box warning

    Posted by Louise on 2nd Sep 2020

    This is the product our pediatric naturopath recommended, along with the Danish protocol of 2 mg on day 1, followed by 1 mg weekly for 3 months.

    Just what I needed.

    Posted by Leighan on 11th May 2020

    I n am so grateful I was able to buy this here. It was sold out everywhere and we needed it desperately for our newborn.,the liquid is very thick! So getting drops into the baby at one day old was tricky but it’s gotten easier as he has gotten older. Very thankful I was able to find it here.

    Really happy to have a trustworthy alternative to a Vitamin K injection for my newborn. This has been my second purchase of this product as this will be my second baby in need of the Bio-K. Shipping is quick, price is reasonable, and the company as a whole is on the level. Thank you! :)
