The large size might make it difficult to swallow for those who struggle with taking big pills.

The high vitamin content makes it great for megadosing, and it feels like a miracle boost when you take it while feeling under the weather! The price is also quite affordable.

비타민C 1000mg

When megadosing, increase your intake until you reach the maximum amount that doesn't cause diarrhea - that's your optimal dose. Keep gradually increasing until you reach 12 tablets a day.

While it's good value for money, the tablets are smaller than Korea Eundan or Yuhan's Vitamin C, and the effectiveness isn't as impressive.

However, it could be a good starting point for beginners trying megadosing for the first time.

Although it's slightly less potent, the lower price makes it more accessible, which can be an advantage.

As someone with atopic and extremely dry skin, my skin barrier breaks down easily, leading to frequent skin inflammation. I've had atopic skin since childhood and have struggled with it my whole life. It seems there are more ingredients that don't agree with my skin than those that do!

I've been megadosing Vitamin C for about 5 years now. (I take 120,000mg daily - that's 12 tablets!)

I started with the most famous brand, Korea Eundan, but switched to Yuhan's pharmacy-only product on a pharmacist's recommendation. Then someone suggested CKD's product for its value, so I tried that.

Nowadays, I rotate between these three brands, but today I'll review CKD Health's Vitamin C product.

I usually buy the 600-tablet bottle online for under 30,000 won. It's probably the best value compared to Korea Eundan or Yuhan products, which is why it seems to be the most popular choice.

At first, I thought it was incredibly cost-effective, but when I received the tablets, I was a bit disappointed. As you can see in the photo, the pills are smaller than Korea Eundan or Yuhan's products (which are the same size as each other).

I'm quite sensitive to supplements and can quickly tell how they affect my body. Honestly, among regular Vitamin C supplements, I found Yuhan's pharmacy product to be the best, followed by Korea Eundan, and then CKD.

I take CKD's product mainly for its value, but in terms of how it makes me feel, both Yuhan and Korea Eundan are far superior for boosting my immunity and improving my skin condition. That's why I actually prefer mixing CKD's product with Yuhan's (Korea Eundan is the most expensive, by the way).

So, when my immunity is really low, I just take Yuhan's. Otherwise, I mix CKD and Yuhan. I often receive Korea Eundan as gifts, so I have plenty at home and end up taking it alongside CKD's product.

If possible, I'd recommend getting Yuhan's Vitamin C from a pharmacy. It's really good.

And megadosing is great! Start with 600mg and if you don't get diarrhea, gradually increase to 1200mg. I had gastritis, so I started while eating cabbage.

You'll see improvements in your skin, joints, immunity, atopic dermatitis, and rhinitis - just like I did!

I'm not quite sure about the effects yet. I'm hoping they'll work well. I'll keep taking them and see how it goes.

I bought these after my eye surgery, and they're so easy to swallow - they go down smooth as honey!

I've been taking it consistently for a long time, so I don't have any complaints!

Great value for money and comes in a large size, so I always take it consistently! The high concentration seems to boost my immunity and helps me avoid catching colds.

Hmm, how to fill 20 characters... There's really nothing to complain about!

I've been consistently taking my vitamins with this product. The price is great, and I can't find any real downsides, so I keep repurchasing it.

If you happen to put the pill in your mouth and delay drinking water, it starts to dissolve, leaving a sour taste.

This vitamin supplement offers great value for money due to its affordable price. The dosage is just right, and I usually take one pill a day. On days when I'm feeling particularly tired or low on energy, I sometimes take two. The packaging is neat, and it's convenient that you can detach individual pills to carry with you.

Nothing in particular. I think the key is to take them consistently, regardless of what they are.

It was pretty decent overall. I always make sure to take supplements like these, and the price was reasonable too.

When I took it on an empty stomach in the morning, the medicinal taste was too strong, so I prefer taking it after meals.

I bought 200 tablets in early August and I'm still taking them. Taking one a day, it seems to last quite a while. The corn-derived ingredients are worry-free, and since it's water-soluble, it absorbs only what's needed and the rest is excreted, so there's no concern about accumulation. This makes it easy to take with peace of mind. I'm usually very picky about ingredients when choosing supplements, but I felt there was no need to spend a lot on expensive Vitamin C, so I went for this Chong Kun Dang Vitamin C. It was also the most affordable option. It's a product that sticks to the basics, and I'm very satisfied with it. With consistent intake, I've noticed I rarely get canker sores anymore, which is great. I used to get them easily when tired, so the fact that I'm not getting them now suggests it's helping with fatigue recovery.

No complaints, but remember to take vitamin C with food! Taking it on an empty stomach might upset your tummy.

I love that it's affordable. While it's a bit inconvenient to carry around, it seems to work well.

The pills are on the larger side, so they're a bit uncomfortable to swallow. The taste is quite strong.

Individually packaged, making them convenient to carry around, and the price is reasonable too.

It's a good idea to skip a dose now and then if it feels overwhelming.

Sometimes it gets stuck to my tongue and doesn't go down easily. It's too harsh to dissolve in your mouth, and too hard to chew. When I take two at once or make sure to take it daily, I feel like my lower right back gets a bit swollen, though that might just be my imagination.

I can't really tell the difference between this and the high-end 1000 brand. In terms of size and effectiveness, I don't notice much difference, but this one is cheaper and you get more product, which is great. (Note: It's smaller than the high-end Gold version though.)
