I have been suffering with lower back pain (besides the positional vertigo and other symptoms I have) for a few months now, never used to have it. I watched several of Dr. Berg’s videos on YouTube regarding Vitamin D and Vitamin K2 deficiency and their link with several symptoms people suffer with. I encourage people to check his health videos out as he informs us of the probable causes of our symptoms and doesn’t just try to mask the symptoms and then they inevitably come back when we haven’t gotten to the root causes of our ailments and solved them at that level. So anyway, I’ve followed what he said on the video and have been taking Vitamin D each day; now when I take walks these days I noticed that the lower back pain is much better and sometimes altogether gone. I’ve been taking 8,000 to 10,000 IUS a day and also trying to get some sun each day and I believe my back pain will be gone soon and hopefully the remnant of the positional vertigo I’ve been suffering from will be gone as well. Remember to watch Dr. Berg’s YouTube videos on Vitamin D and Vitamin K for the full story.
