Really like this Ester-C formula with a great addition of bioflavonoids which is also non-acidic and doesn’t affect my stomach acidity. One of the most essential supplements when it comes to thyroid and adrenal health, iron absorbability, antioxidant content, as well as coping with viruses such as coronavirus. One of the best Vit C formulas on iHerb P.S. don’t forget to ✨thumbzzz upp✨ if you like my review

Recently I visit a dermatologist because of acne-prone skin. And she suggested taking vitamin C. It helps to protect cells and keep them healthy. It's good that Ester-C has vegetarian capsules as well. I can see improvements on my skin. I also take zinc and B-12 as well. Maybe a combination of these 3 is working well.

I love this type of vitamin C and the added bioflavonoids are an excellent addition to the product. I take 1-4 capsues per day as I need a lot of vitamin C. I can take this amount as it doesn't uset my stomach in any way. Will keep buying it.

The size of capsule is easy to swallow and absorbs quickly to digestive system and it’s easy on the stomach. Its potency is 500 mg for 2 capsules, you can take 1 if you need smaller dose. It boosts your immune system. This brand is very high quality and ingredients are very bioavailability.

I used to take ester-c regularly in the past for a long time and I was very happy with the results. It helped boost my energy levels and overall wellbeing and It is gentle on my stomach. The capsule is a bit bigger than I wished but it’s manageable.

This is the best ester-C vitamin, great quality with added ingredient - bioflavonoids in the greatest quantity of all ester C vitamins. It is 500 mg, and its pitty it it isnt 1000mg, so you need to take 2 capsules. Its great for your stomach and for kidneys as it will not faciliate creation of kidney stones, or at least the effect is considerably lower.

Ester-C is proven over and over that they know how make the best quality Vitamin C. It doesn't upset the stomac and the capsule on a smaller size. I do prefer 500 mg potency because I can give to a younger child smaller dosage. It's the best for immune system in the winter season.

This product is a supplement for improving health, immunity, quality of life, well-being and mood. I bought it out of curiosity after reading "Vitamin" in the title of the search results. It filled some essential needs I had so far: energy boost and eliminated fatigue due to long flights and stress. Its highly recommended Brand!

There are many vitamin C products to choose from. I have been taking this brand for years because it is easier on the stomach lining.
