I started taking this supplement just a couple days ago, and today I've started experiencing heart palpitations, shortness of breath, and anxiety. In doing some research it appears that about 1/3 of the population has a genetic inability to rapidly process MK7, and these symptoms are the side effects (headaches are another which, thankfully, I haven't had). I'm stopping supplementing immediately, and I'd like to thank some of the other negative reviewers for sharing their side effects. If I hadn't read those reviews before purchasing this supplement, it would have taken me a lot longer to make the connection between my symptoms and this supplement.

I had terrible heart palpitations and feelings of anxiety from taking these. I took 1 per day for 4 days before I realized they had were probably the cause of the palpitations. It took a full week for the palpitations to stop after stopping the pills. Once I was pretty sure it was the vit k and I had stopped taking them for well over week, I took it one last time just to confirm, within several I had the palpitations again. they were so bad I could sleep. Takes a while to get out of your system too. It's been almost 48 hours since taking just 1 pill. And still have palpitations, though milder still there. Horrible feeling. This is only brand of k2 ive tried. Afraid to try diff brands.
Update: it seems my problem with k2 was tied with coq10 depletions caused by taking a statins. (If your on a statin, please take coq10 with it!!!) I've since gotten off the stating and taking coq10 daily. I started taking the k2 again and it hasn't given me little if any palpitations.

I'd caution against this product, for a couple of reasons.
1) Personal experience: Unfortunately, this product made me feel terrible, as it did some of the other reviewers. I purchased this brand, being curious after taking Carlson's K-2 product and wondering if a combination of MK-7 and MK-4 forms would be even better since I had such good results with Carlson's. Wow. Once I figured out what was making me feel so lousy I quit it for me, and my family, right away.
2) Suspicious reviews: It's very interesting to me that the "most helpful" review by 'RWM' is authored by the same person who reviews almost every other Innovix product and another associated brand (OmegaVia) with a stellar five star rating. Many of the review start out the same..."Here's a side by side comparison of ten leading...." These views are copied virtually verbatim on the other 9 products, if not others. (Maybe that's how I found this product, was his review of Carlson's K-2)
3) No other information: Innovix labs is virtually unheard of outside of Amazon, except for it's own website. I can't even get it to come up on other supplement seller's sites. (Try a google search for immediate verification.) Seems to be driven more by marketing than anything else.
I would steer clear and try one of the other "9 leading products" he mentions. I'm going back to Carlson.

From the second day I began taking this I have had unwavering anxiety and I couldn't understand why. I was having irregular heartbeats and trouble sleeping. I've also been having tightness in my forearms and calves, like I just cant stretch those muscles enough. I thought to myself, what has changed in my life that this is happening to me? I linked it up with this K2. Stopped taking it and started feeling better after about 3 days. I guess it just isn't for everyone. Im going to try the MK-4 stuff next week and hope that the same thing doesn't happen.

I haven't had any tests, started taking this to ward off osteoporosis and arterial sclerosis common in my family. I'm going to switch as I'll get a better deal if I buy a 5 mg of MK4 and a separate 100 mcg. MK7. I took the bait for that guys lengthy dissertation on the merits of the different brands of K2, while it looks informative I'm not so sure. This one is nice and easy to take as they are small soft gels. I can take a 5MG MK-7 twice a week and the others daily with my D3. I plan to add Strontium Citrate too.

After reading up on the benefits of K2, I ordered a couple of bottles and gave it a try. One thing that I noticed immediately was that it made me gassy and constipated -- something that I hadn't noticed in other people's reviews. My wife had the same reaction -- she stopped taking it immediately. After a about a month, I noticed something else -- I started feeling old (I'm 57). That is to say, I started feeling much weaker than normal. Things that didn't used to feel heavy suddenly did. The only thing that had changed in my routine was the K2, so I stopped taking it, and within a few days my strength returned. I recognize that everyone responds to drugs differently, but that was my experience. If you're having the same side effects, you're not alone.

I get fairly severe heart palpitations whenever I take one of these pills. Typically I will take one at 8 PM and then I wake up at 1AM with cold sweats and heart beating like crazy. I was only taking this once or twice a week. I guess I will need to get my Vitamin K from food sources.

This made me feel really irritable and tired. Glad I saw the other reviews or would not have made the connection that it was this product. Stopped taking it and felt fine right away. Returned it and complained about it on their website.....Beware!

I just switched to this k2 supplement from NOW's mk7 k2. I didn't have any trouble with the NOW brand but switched to these because they were soy free and had mk4. I've been taking them for two days and have had a bad headache for both days....and I'm not a person that gets headaches very often. I know the brain really utilizes the mk4 so I'm wondering if my brain was just starved for this stuff or if this supplement just doesn't agree with me. I'm going to try to decrease the dose tomorrow (I was taking two) and I'll keep everyone posted. I don't want to automatically blame this supplement but both times the headache started about two hours after taking it.

In January and February I used and then ceased using the product twice, as it appears to have caused insomnia, day-time drowsiness, and strange feelings at times. It may also have caused a rise in blood pressure. I have no problems with NOW MK-7, and so I assume it is the MK-4 that caused the problems.
Starting today, I am going to try it again.
5/19/16: After 10 days the problems began again. I will no longer use Full Spectrum VITAMIN K2 by Innovix Labs.
