Why Doesn’t Qualia Vision Have Vitamin A?

Vitamin A is an important vitamin for eye function because it’s needed by the photoreceptors that capture light. But because vitamin A is fat-soluble, it accumulates if taken daily, which has the potential to lead to toxicity. 

Vitamin A deficiency is extremely uncommon in the United States and other developed countries. Because of the combination of being very rarely needed, accumulating if taken every day, and having potential for toxicity, we do not think vitamin A should be routinely supplemented unless a person is deficient, so did not include it in Qualia Vision, which was formulated to be taken for extended periods of time. 

Qualia Vision was also formulated first and foremost for persons with high amounts of screen time and blue light exposure. 

Based on animal research, it does not appear to be a good idea to give vitamin A under these circumstances—limiting dietary vitamin A has been more protective in animals exposed to blue light.
