I took a bottle of it. Lasted a little more than a month and didn't notice any appreciable benefits.
Incidentally, I just took another low dose of MB (.76mg) and within 15-20 minutes the mild chest pain started presenting. I haven't taken fish oil in two days and the MB is the only supplement I took today due to being sick for the past 3 days with food poisoning. I've spent so much time in the bathroom evacuating that I would imagine most anything I had in me has been flushed so the MB is pretty much the only thing I have ingested.
What does chain pain indicate to you? If it was you, would you stop taking it or is this a side-effect that could likely go away?
Oi. This is a puzzle, and distressing. Well, there are three main possibilities:
1. Heart ischemia.
2. Costochondritis.
3. Esophageal spasm.
There are a few less likely possibilites also: Hiatal hernia, or an air bubble caught in your esophagus at a constriction point (right above where it enters the solar plexus), or rarely a pleural effusion, or really really rarely a pneumothorax.
The good news is that it isn't the fish oil. I still don't trust fish oil, especially from WallieWorld, but at least we know that's not it.
It does appear it's the MB. Or perhaps the MB at the higher doses you're taking.
If heart ischemia, the MB by acting as a vasoconstrictor could be causing ischemia in areas of heart served by coronary arteries that already have significant narrowing from arteriosclerosis. This is serious, frightening, no-fooling-around stuff: if a plaque breaks free while the coronary artery is vasoconstricted from the MB, you'll go into a full-fledged heart attack. Let's not do that. I think you should go get an EKG from a doctor or E.D. if you're having chest pain...it's the only way. That, and cardiac enzymes. Then you'll know for sure. If you are old enough to possibly have arteriosclerosis, you may wish to try the Linus Pauling protocol, which is essentially Vit C and L-lysine, 1 gram of each 5 x day. Some people have improved tremendously in just weeks on that.
It might be costochondritis, but you really should rule out myocardial ischemia first. If it's costochondritis, that's pain / inflammation / "arthritis" of the junction between the ribs and the cartilage of the chest plate - the sternum. The pathognomonic feature of costochondritis is that you can reproduce or exacerbate the pain reliably and completely by simply pressing in on the ribs or between the ribs at the painful locations. But, it doesn't seem to me that MB is an inflammatory agent, so I doubt it would exacerbate costochondritis, and I certainly cannot see how it would cause it.
Esophageal spasm is a real possibility, but, again, only after ruling out MI. In some people, especially if they have an esophageal stricture or hiatal hernia, they can get into esophageal spasm from an irritant. The MB doesn't seem to me to be a GI irritant, but I'm only taking 60 mcg. Maybe at much higher doses the MB is causing irritation of the esophageal mucosa, and then there's spasming going on. This type of pain, by the way, is really awful - people who get into esophageal spasming are not happy campers.
The way you tell esophageal spasming, aside from fancy testing, is by first ruling out MI with EKG and enzymes, and then trying a dose of donnatol. If it goes away quickly with donnatol (sp?), then it's probably esoph. spasmg.
I dunno if this helps, but I'm just trying to provide some direction. Are you old enough and do you have risk factors for serious coronary artery disease?
