Repurchase! Esther C is an invaluable vitamin C which isn’t sour and has no accumulation risk in the kidneys. It's a powerful antioxidant that supports vessels, amino acids, iron absorption, and the immune system. Working twice as effectively and lasting longer, I noticed a brighter complexion, increased energy, and smoother skin without any unpleasant side effects. I recommend drinking at least 2 litres of water daily. Reorder!

Excellent vitamin C! This is not my first order; my family has been taking it for over a year, and we've nearly stopped being unwell. At the first signs of sickness, I take 500 mg two to three times a day.

I have been taking this great vitamin C for three months, and I've noticed improvements in my blood vessels; my varicose veins have decreased significantly. I’m pleasantly shocked and highly recommend it.
