Frequently Asked Questions About Sisu Vitamins & Supplements

What is Ester-C® and how is it different from regular vitamin C?

Ester-C® is a unique and patented form of calcium ascorbate that is created by buffering ascorbic acid (vitamin C) with calcium. This special formulation provides numerous health benefits, including support for skin, joint, and vision health, cardiovascular support, antioxidant protection, and immune system wellness. Unlike regular vitamin C, Ester-C® is non-acidic and gentle on the stomach.

Why is Ester-C® considered quick-absorbing and highly bioavailable?

Ester-C® is better absorbed and more bioavailable compared to regular vitamin C due to the presence of active vitamin C metabolites that are exclusively found in Ester-C®. This unique composition ensures rapid absorption into the bloodstream, allowing for optimal utilization by the body.

Is Ester-C® gentle on the stomach?

Yes, Ester-C® is non-acidic and gentle on the digestive system, compared to standard vitamin C, which may cause stomach discomfort or irritation in some individuals. This makes Ester-C® a suitable choice for those with sensitive stomachs or gastrointestinal issues.

What scientific evidence supports the efficacy of Ester-C®?

Ester-C® has been extensively studied for decades and is backed by scientific research. Its patented formulation goes through rigorous testing, making it one of the most researched buffered forms of vitamin C available.
