Improved skin texture

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!

I’ve struggled with a bleeding nose since childhood. Since starting on Rutin and Vitamin C, my symptoms have improved significantly, as the bruises that once appeared from minor bumps are no longer an issue.

Headache relief

This is love. Since adolescence, I’ve suffered from headaches in crowded places. I started taking this vitamin C for immunity, but discovered it helps oxygen enter the cells, including the brain. My headaches diminished and eventually disappeared altogether. I consume vitamin C daily, now mostly as pure powder from the same brand. I've not been ill for several years and hope it strengthens my immune system during the pandemic.

Reduction of illnesses

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.
