                                According to the National Institutes of Health, vitamin B5 (pantothenic acid) is generally considered safe, with no established Tolerable Upper Intake Level due to the body's efficient excretion process. However, taking very high doses through supplements can cause mild side effects like gastrointestinal distress.
