Ester C finally I purchased it

Why I was searching for this so much? Because Ester-C can be offered by many companies, but this product stands out with its 400 mg of flavonoids in just two capsules — not too much, not too little. You can research how important it is to take this together with vitamin C. Should you buy it? Yes, you, the one inhaling carbon dioxide instead of oxygen every day. Smokers, I'm talking to you! Every cigarette you smoke depletes your body of 25 mg of vitamin C. You need this. I start my day with two capsules and will gradually reduce it to one capsule. Vitamin C is an antioxidant, and the Ester-C formula stays in the body longer compared to acidic formulas, allowing it to work more effectively. One of the key benefits is that it doesn’t cause kidney stones or increase stomach acidity. Ester-C + flavonoids = an excellent choice!

Very Happy

I have noticed since switching from Vit C's derived from Ascorbic Acid to Esther, I have less stomach sensitivities, I have noticed increased healing taking this supplement, and easy on my digestive system, I started off with the smaller bottle to test it out, and then realised how well it was working, so I bumped up the dosage/bottle size, Im very happy with this product....Jesus Bless you all in your health and healing, His coming soon, Revelation and John 3.16 :-)

Gentle on the stomach

I bought this vitamin C a long time ago. I don’t clearly remember its effects, but I do recall that it was gentle on the stomach, which is a big plus for me. Regular sized capsules.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach-no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and | love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!

Gentle to stomach

This vitamin C is non acidic so you can take it even on an empty stomach. When we have flu we will take 2 or 3 capsules in separate doses so that it will be fully absorbed. And it contains citrus complex which is superior to just ascorbic acid as C vitamins. Superb quality!

These are my go-to Vitamin C. The capsules are slick and very easy to swallow. They have no taste - so don't leave an after-taste - and importantly -do NOT cause gas as some vitamin C does. I have been taking several of these every day and have not had any problems.
