I just found this about niacin and Vit C from WebMD:

Niacin interacts with VITAMIN C (ASCORBIC ACID)
Taking niacin with vitamin C and other antioxidants can decrease the effects of niacin on good cholesterol levels. It is unknown if vitamin C alone decreases the effects of niacin on good cholesterol levels.

It is unclear whether they mean taking vit C & other antioxidants at the same time as one takes the niacin, or whether one should not take C and other anti-oxidants at all if one is taking niacin.

It also is unclear just what they mean by “other antioxidants”. Do they mean all other antioxidants or just some, or maybe they just don’t know.

For example, I also take trans-Pterostilbene. It is a stilbenoid, but is marketed as “antioxidant support”.

Or QH-PQQ, which is a dual anti-oxidant support for energy and cardiac support.
