Comparison
Melatonin vs MCT Oil
Melatonin
Pineal hormone regulating circadian rhythm. Low doses (0.3-1mg) often outperform higher doses for sleep.
MCT Oil
Medium-chain triglycerides metabolised directly to ketones in the liver. Provides rapid brain energy substrate; useful for ketogenic protocols and cognitive support.

The comparison in plain English
Auto-generated from dataMelatonin and MCT Oil are both in the neuroprotective category respectively. Melatonin Pineal hormone regulating circadian rhythm. MCT Oil Medium-chain triglycerides metabolised directly to ketones in the liver.
Bottom line
Melatonin (evidence A, safety 5/5) has a weaker evidence base than MCT Oil (evidence B, safety 5/5). Melatonin has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Melatonin if
Melatonin is the better fit when your goal aligns with its mechanism (Endogenous hormone produced by the pineal gland in response to darkness, signalling the circadian sleep window) and the dose range (0.3–3mg) suits your protocol. Half-life is 1h.
Choose MCT Oil if
MCT Oil is the better fit when your goal aligns with its mechanism (MCTs bypass the standard fat digestion pathway, absorbing directly into portal circulation and metabolised by the liver into ketone bodies (beta-hydroxybutyrate, acetoacetate)) and the dose range (5000–30000mg) suits your protocol. Half-life is —h.
