Vitamin E product ingredient levels and light sensitivity

[Dan W]

Another study suggested by the anonymous study-person:

Interesting excerpts:

Tablets exposed to natural sun light or UV source depleted vitamin E significantly within 5 h, approximately 50% for both lighted conditions.

I would guess the effect is even stronger on the liquid vitamin E's some of us take.

There was a relatively high tight correlation (R[sup]2[/sup] = 0.8266) between tablet price and its vitamin E content. Customer should buy the higher price products rather than the cheaper ones to get sufficient amount of vitamin E.

That's referring to the Vietnamese market, but I would guess it might hold true elsewhere.
