Headaches in the First Week: What to Actually Know

2026 guide · Memodyne Wellness Desk

Beyond the niacin-flush effect already covered, some people report a mild headache during the first week specifically — worth a direct, separate explanation.

Why this can happen

Ingredients that affect blood vessel dilation can occasionally cause a mild, temporary headache as your body adjusts during the first several days, distinct from the skin-flushing reaction niacin specifically causes.

What to actually do

Stay well hydrated, take the capsule with food if you haven't been, and give it a few days to see if the effect settles — contact your doctor if headaches are severe, persistent, or accompanied by other symptoms.

💊 Medical note: because Memodyne contains nitric-oxide precursor amino acids, show the label to your doctor first if you're pregnant, nursing, under 18, or take medication for blood pressure, blood thinning, nitrates, or are on a PDE5 inhibitor or vasodilator.
