my mom just told me i need 1200 mg of calcium a day. she also said caffeine blocks the absorption of it. i’ve been a coffee in the morning guy for years and it’s also the only time of day i have milk with my cereal. should i take some calcium citrate supplements once in the afternoon and again at night, daily? in theory, after the caffeine has worn off for a while….
It’s blocks VERY LITTLE calcium. In fact some milk in your coffee will offset this. So any calcium you eat will be absorbed even if you drink coffee exclusively as your fluids for the day (which I would NOT recommend for any reason).
Do not supplement calcium. Completely unnecessary and it can deposit into arteries and other tissue. Drink some milk and eat real cheese. Try to take 5,000iu of vitamin d a day and get your vitamin d tested. Also throw in vitamin K2 and magnesium for optimal absorption.
The best way to know it is to do a blood test. The thing about calcium is that it can accumulate in your body and by taking calcium just because your mom told you so, well, it can have negative effects later.
Your bones act as a store of calcium, and if your intakes are insufficient, your body will mobilise skeletal calcium where necessary. Most people are getting broadly enough, but if you’re concerned, you’re better off taking vitamin D supplements (particularly if you’re dark-skinned or work indoors) so you can get more of your dietary calcium into your bones.
It doesn’t block the absorption, but it can raise your blood phosphorous levels which can result in higher calcium excretion. Ofc this is regulated by hormones and kidney function, do you happen to have CKD?
the obsession with calcium is sorta an American thing and odds are, you’re getting enough. Part of this belief is due to dairy industry lobbying and not science. There doesn’t seem to be any significant benefit to excess calcium in preventing fractures (in fact, more calcium seemed to make it worse). If you’re eating a diverse diet, you’re fine. The coffee also isn’t concerning.
Very little as blocker, but could influence where calcium goes not to bones but blood vessels. Research did find cortisol continues to rise upon waking and tapers about 10am. Caffeine raise cortisol, so benefit is add caffeine after 10am. Too high cortisol levels are bad for us.
Caffeine leaches calcium from bones, sapping their strength. You lose about 6 milligrams of calcium for every 100 milligrams of caffeine ingested…That’s not as much of a loss as salt, but it’s worrisome, nonetheless.
