Hi! I moved your post here where more people interested in the topic will see it.
Oncovite is a daily multivitamin that is promoted by Dr. Donald Lamm, who is known for his work with BCG. There is a similar product, Bladder 2.2, which is sold under the auspices of a group of urologists. The operant word here is "SOLD."
These are both high quality vitamin supplements sort of similar to Ocuvite which is promoted for eye health. As my urologist said if you want to take a daily vitamin, they can't hurt but they won't cure anything. They are relatively expensive.
They don't have anything to do with BCG (except for Dr. Lamm's involvement in the promotion of Oncovite)
