Hello, does anyone know this product? http://www.yasoo.com/products/aqua-e/ Seems like a good form o Vitamin E, with all of its components. I'd be interested because it's in liquid form. I tend to absorb liquid supplements better, plus I don't do digest very well the oily gel capsules. Opinions? It has preservatives (potassium sorbate). Is it a concern? Thanks in advance.
