This is a reliable brand and I like the fact that this Vitamin K has both types of K2 as well as K1. I have used just K2 for a long time until I read an article about the benefits of K1, so thought this would be a great product to try. The price is excellent for the number of servings--2 months' worth. My orders always come in good time and the packaging is good. I have rarely had anything damaged in shipping.
This is not medical advice! Just some facts: as someone living in Brazil, my diet is low on DARK green vegetables and rich nuts, although I have access to bovine liver and animal guts (that I personally don't like). K1 is actually easy to complete dietary demand with other leaves, but K2 is not. And the last has been shown that is important for regulation on seric calcium vs. blood vessels elasticity and nitric oxide metabolism. K2 also lasts more than 24h (long half-life) after ingested as supplement, so I personally skip dosage a day. The ingredient list seems complete [if you are wondering about K3, it's a metabolite of Phito (K1) and Menaquinone, or either made artificially in lab to fight of anticoagulants effect]. Addendum: You also need good intestinal microbiota and liver health to metabolize Vit K! Even consuming 48-48h I noticed my menstrual flow is not presenting in spots now after a month of use. And I reenforce: not medical advice! Just an observation. Since vitamin K is bounded with fat, suggestion is ingesting with Vit D (best) or E, or even fish oil. If your diet is low on fat or your using other medications as anticoagulants, antibiotics, or products for weight loss, please, dear, consult a doctor! Thumbs up if I clarified any of your doubts.
There is no pill or drops that make miracles that's just a fact. But I do know the difference when taking these and not taking these. It helps a lot with focus, if I don't take them before class I definitely noticed I'm wondering off a lot more. So far a all natural supplement it has a huge improvement compare to pharmaceutical drugs. Pharmaceutical drugs are terrible for you and I prefer a all natural remedy. That's why I have this a 5 star review because it's the best natural remedy for add or adhd. I definitely notice a big improvement. I will be purchasing again. No taste, medium size pill, great quality, dosage 2, health benefits, great quality!
