Positive experiences
“i believe k2, B vitamins, and amino acids L carnitine and glutamine made a difference in my skin.”
“It was magnesium, vitamin D and K2, zinc, and fish oil. One of those really got my gut right and stopped the random panic attacks.”
“I noticed more energy and almost cured my allergies, runny noses and constant colds/flu with D3+K2 and Magnesium.”
“Second this. I didn't know you needed k2 with vitamin D for a long time, and it made me feel weird too. But with k2 you'll feel amazing.”
“Take K2 to assist calcium redirection with vitamin D. Also noticed when I have body aches and pains, taking K2 makes them dissipate. Works better than magnesium.”
“Started with 10,000 iu a day, now just do 5,000 with K2 and I feel like a whole new person.”
Negative and mixed experiences
“MK4 is more tolerable, MK7 caused heart palpitations and anxiety for me.”
“A week and a half ago I added vitamin K2 MK4 (Thorne droplets, 1-2 per day)...and now I haven't slept properly in 10 days.”
“I started getting some uncomfortable sides with high dose k2 (Thorne liquid drops). High blood pressure and a constricted feeling around my chest.”
“Yeah vitamin d with k2 will definitely help with sleep. I have the best sleep since suplementing with d.”
“I seem to get inconsistent yet significant results from Vitamin K2 supplementation”
