Why office workers run short on calcium, magnesium and vitamin D
"Calmadi" is the Korean shorthand for calcium, magnesium and vitamin D together. Since I'm stuck in the office all the time these days, I've been running low on calmadi!! You've all heard of calmadi, right?!?! 🐟👁☀
It's something office workers especially tend to miss!! Staying indoors means we get less calmadi than people who are often outdoors!! So today I've brought a health supplement for office workers with built-up chronic fatigue! Calmadi, here we go~~! ٩(◕ᗜ◕)و

The calmadi I brought today is Cal Ma D K2 from Switch On~~!!

Can 2 tablets a day cover calcium, magnesium and vitamin D in one go?
Switch On Cal Ma D K2 is calmadi that's done in 2 tablets a day! You can sort out your daily calmadi so easily, isn't that super convenient?!?! ( •̀∀•́ )✧


Especially! Ediing here, who stares at a monitor a lot, sometimes works so hard that my eyelid starts twitching!! Switch On Cal Ma D K2 also has magnesium in it, so there's no need to take magnesium separately. Two calmadi tablets and done!!


We all take vitamin C often, but calcium, magnesium and vitamin D supplements are such a pain to keep up with separately, right?!
But with Switch On you don't have to juggle this and that. Cal Ma D K2 alone covers the nutrients you're missing, which I found really convenient!!!

How are the individual packs, tablet size and taste?
Switch On Cal Ma D K2 comes individually packed with 2 tablets per day, so it's easy to take and hygienic!


The tablets aren't too big either, so they went down comfortably with water!!

There's no particular taste or smell, so nothing off-putting, and taking 2 tablets every day feels no burden at all!! (*•̀ᴗ•́*)و ̑̑


Who is Switch On Cal Ma D K2 recommended for?
Office workers! Not just middle-aged and older adults but growing kids can take Switch On Cal Ma D K2 too! The individual packs make it easy to carry, so I recommend it as a supplement that's easy to take every single day! 👍🏻
