Memocept Side Effects: The Niacin Flush, the Tingle and Who Should Ask First

Medically reviewed by Dr. Patricia McKeon, Neuropsychologist

Memocept side effects are usually mild: some people notice a warm niacin flush of the face and neck in the first days, and some feel a harmless beta-alanine tingle. Memocept has no caffeine and no stimulants, so it is not built to touch your sleep. The bigger point is interactions: L-arginine and L-citrulline raise nitric oxide, so ask a pharmacist first if you take nitrates, blood pressure drugs or erectile dysfunction drugs.

What is the Memocept niacin flush?

The niacin flush is the side effect people mention most. It is a warm, red feeling on the face, neck and chest, sometimes with itching. It tends to show up 15 to 30 minutes after the capsule, mostly in the first days.

The site describes it as harmless, and alarming only if nobody warned you. Reviewers on the site mention it: Maria G. had one on day 2 and now takes the capsule with food. Taking Memocept with breakfast is the simplest way to soften it, and it usually fades within a week or two.

The NIH Office of Dietary Supplements sets the upper limit for supplemental niacin at 35 mg a day because of this flush. The milligrams per capsule are not published, so count every other product you take that has niacin in it.

What is the beta-alanine tingle?

Beta-alanine can cause a light pins-and-needles feeling on the skin, called paraesthesia. The site calls it harmless. It scales with the dose, and it is short-lived.

The tingle is the ingredient arriving, not the product working. If you feel it, there is nothing to do, and it is not a sign that you took too much.

Does Memocept affect sleep?

Memocept has no caffeine, no guarana, no green tea extract and no stimulant blend. Taken in the morning, it is designed to leave your sleep alone. Several reviewers chose it for that reason.

If you feel wired or restless, look at the rest of your day first: coffee, tea, energy drinks and pre-workout powders all count.

Which drugs should you ask about before taking Memocept?

• Nitrates and erectile dysfunction drugs. L-arginine and L-citrulline raise nitric oxide, and so do these drugs. Stacking them can drop blood pressure further than intended.
• Blood pressure drugs. Citrulline lowers blood pressure on its own, so an added effect is plausible.
• Statins. Niacin has documented interactions with statins.
• Blood glucose control. Niacin can affect it, so tell whoever manages your prescriptions.
• Surgery. Stop supplements with vascular effects well before a planned operation and tell your surgeon.

Bring the bottle to your pharmacist rather than a photo. It takes about two minutes to check against your list.

Who should not take Memocept?

Memocept is for healthy adults 18 and over. It is not for anyone under 18, or anyone pregnant or nursing. If you take nitrates, blood pressure drugs or erectile dysfunction drugs, speak to a prescriber before the first capsule.

It is also not a fit if a niacin flush would bother you. That is a fair reason to pass, or to use the 60-day guarantee after a month of use.

How do you lower the chance of side effects?

Follow the label: one capsule each morning with water. Never take two to catch up on a missed day. If you flush, take it with breakfast.

Frequently asked questions

Our view

The side effects on record for Memocept are mild and well known: a flush from niacin and a tingle from beta-alanine. The part that deserves real care is the drug list, because the amino acids in this capsule act on blood vessels.

If you take nitrates, blood pressure drugs or erectile dysfunction drugs, talk to a pharmacist before you start. If you do not, the routine is one capsule with breakfast, and the 60-day guarantee gives you time to decide.
