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.

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!

Good

I have been using this brand of ester c for awhile. It is non acidic so I take it in the morning- no problem. It helps with immunity especially during rainy season. The size is normal and there is no taste. The 500 mg is good enough to keep one healthy.

BEST vitamin c supplement hands down, they nailed it with this. I’m telling you, NAILED IT. Immune system not getting sick, skin feels better easy to swallow pills. This company killed it with this product and I will be using this product year round moving forward. Immune system is so important, quality vitamin c worth your money trust me best vitamin c supplement you’d buy. Does not bother stomach AT ALL!

Immune Support Without the Stomach Upset I love this form of vitamin C! Ester-C® is much gentler on the stomach than regular ascorbic acid, and I’ve had zero irritation or acid issues even when taken daily. It’s a great way to support immunity and overall wellness—especially during cold season. The added citrus bioflavonoids are a nice bonus for absorption. Highly recommended!
