What happens with high doses of pantothenic acid (vitamin B5)?

Explanation:
High-dose pantothenic acid often leads to diarrhea because large amounts can irritate the gastrointestinal tract and draw water into the gut, causing loose stools. Pantothenic acid is a water-soluble vitamin, so excess is usually excreted, but when intake is very high, the GI tract can become upset, with increased motility and osmotic effects contributing to diarrhea. The other listed effects—hair loss, insomnia, and palpitations—aren't characteristic adverse effects of taking big amounts of vitamin B5.
