Myristic acid is a long-chain saturated fatty acid (C14:0). Palm kernel oil, coconut oil, nutmeg, butterfat, and some animal fats supply it naturally. It functions as a structural component of cell membranes and may support normal cellular function. People mainly get it through everyday foods, not as a stand-alone supplement. Manufacturers also use it as a dietary fat source in food production.
In supplement products such as MCT oil blends, myristic acid sometimes appears as a minor ingredient. Whole foods and oil blends provide the main dietary source rather than isolated doses. No standard supplemental dose range exists for this fatty acid.
This is a saturated fat. High intake can raise LDL ("bad") cholesterol. More cardiovascular risk may follow for people with hyperlipidemia, existing heart conditions, or a family history of these problems. Long-term safety data on taking isolated myristic acid as a supplement are thin.
