Vitamin B12 doesn't directly decrease estrogen, but it plays a vital role in its metabolism, helping the body process and excrete estrogen, so deficiency can lead to higher estrogen levels or imbalances, while adequate B12 supports healthy hormone regulation, with some studies suggesting B2 and B12 might even slightly lower circulating estrogen in healthy women.
