I hear so much about "everyone is deficient in magnesium." Ok. And then I read but having a magnesium serum test is worthless because your body closely regulates the amount of mag in your body, blah blah, get rbc instead. Side note, I've never seen any documents ever other than self-appointed internet providers who say this, btw, not about serum magnesium being stupid, but about everyone being low in magnesium.
So whatever, I got a magnesium RBC test.
I did copper and zinc, too, for a handful of reasons.
-
Whenever I take zinc, I get tendonitis. I hear this is because it removes copper, and copper is necessary for tendon health.
-
When I took Niagen years ago, I got tendonitis (there's a big thread on longecity were lots of people got tendonitis). Again, I think this may be a copper thing.
And then I did lots of irons because I hear that's important for things, too, and because I have long-covid from the vaccine and wanted to know what my iron levels were.
Ok, so here
ceruloplasmin 28 (18-36)
copper 99 (70-175)
ferritin 66 (38-380)
magnesium rbc 5.5 (4-6.4)
iron total 78 (50-180)
iron binding capacity 329 (250-425)
saturation 24 (20-48)
transferritin 267 (188-341)
zinc 86 (60-130)
I'm a male, 41.
Ferritin looks to be on the low side of normal.
Magnesium looks fine right? I take 100 or 200mg of magnesium lysinate/glycinate per day only because I'm supplementing B1 (another chemical which, surprise surprise, they say blood tests are inaccurate for) and I heard you're supposed to use magnesium with it.
Is my copper low? What copper supplements should one use? I hear copper (glycinate?) is useless and only ultra expensive Cu1 from that certain company is useful. I moreover hear copper is bad and accumulates and you don't want a lot, ever. But I get tendonitis frequently, so...
