This is an excellent vitamin A product. I use this when I feel the very first symptom of illness and I begin taking 75,000 units of A for 3-6 days and I usually avoid catching anything. Anyone will thyroid problems will benefit by this A product as this is the type of A that your body can readily absorb and utilize.

Suggest limited/occasional use only. Vit A increases transferrin - higher doses can be detrimental to anyone low in iron, asthmatics, etc. I do not recommend vit A in this dose because it is too effective - it causes me to get breathless, in a very unpleasant way. I end up having to supplement other things to compensate (when they're normally not necessary). At this dose it's too much of a balancing act - even limited/occasional use, I find it just gets metabolised much too quickly. I want a natural vit A, however it seems impossible to find one in lower doses, especially one that isn't cod. If this review was helpful to you, please click YES below - thank you.

This really helps with night vision. I like that it does not have soybean oil.
