1) While having to take 3 pills a day can be a bit of a hassle, the supplement that contains 250mg of magnesium along with calcium is actually quite rare, so I recommend it. 2) I sometimes take 3 pills at once, but since it's not an enteric-coated formula, it has a high potential to cause stomach issues. So for those with a sensitive stomach or first-time users, it's best to take it 3 times a day. 3) With 500mg of calcium, 250mg of magnesium, 200IU of vitamin D, and 7mg of zinc, this is one of the calcium supplements with a higher magnesium content that I can find at Olive Young. If you don't need to separately take magnesium and zinc, this is a great option with excellent value. 4) As someone diagnosed with osteoporosis, I need to take additional calcium supplements besides this one. (If I don't, my tailbone really starts to hurt!) This nutritional supplement is an excellent value option. 5) While there are a lot of pills, considering the nutritional content, value, and the fact that I've gotten used to taking them over time, I think this is a good choice for me. 6) Other calcium supplements I'd recommend are Alive and GNM products. Alive is a bit more expensive (around 30,000 won for a 45-day supply) but has 700mg of calcium, 350mg of magnesium, and 400IU of vitamin D. GNM has slightly lower amounts but better value. 7) I'd recommend trying out these three options and seeing which one works best for you in terms of tolerability and lack of stomach issues.

The large number and size of the pills, as well as the lack of an enteric coating, which could potentially cause stomach problems.

Don't order this directly from overseas. Just buy it from Olive Young. I once received an expired product from an overseas order, so I absolutely won't do that again.

The fundamental vitamin, the multivitamin, is great because you can just take one and be good. When you're feeling tired, taking it gives you a boost!

Taking 3 tablets per day is a bit burdensome, but since it contains 4 nutrients, I guess there's no helping it...
