Possible Side Effects
Caprylic acid supplements are generally considered safe if used as prescribed. Common side effects include nausea, flatulence, constipation, heartburn, indigestion, and diarrhea. High doses may trigger an abnormal drop in calcium levels (hypocalcemia), causing growth problems in children and an increased risk of brittle bones in people with osteoporosis.
Caprylic acid may not be appropriate for people with liver disease or hypotension (low blood pressure) as an increased fatty acid intake is known to complicate both conditions.
Caprylic acids should be avoided in people with medium-chain acyl-CoA dehydrogenase (MCAD) deficiency who are unable to break down fatty acids efficiently. The excessive build-up of caprylic acid can trigger hypoglycemia (low blood sugar), vomiting, and, in severe cases, coma.
The safety of caprylic acid in children, pregnant women, and nursing mothers has not been established. For safety sake, it is best to avoid caprylic acid unless under the supervision of qualified pediatrician or OB/GYN.
It is not known if caprylic acid supplements can interact with other medications.
