MemoHoney side effects: what you might notice and what to do

MemoHoney side effects, when they happen, are usually mild and short. The ones linked to its ingredients are a warm niacin flush, a light beta-alanine skin tingle, and an upset stomach at large doses of arginine or citrulline. Most pass within an hour. Talk to your prescriber first if you take a nitrate or a blood-pressure medicine.

MemoHoney side effects at a glance

MemoHoney is built from sports-nutrition staples: two forms of arginine, two forms of citrulline, niacin and beta-alanine. One good thing about that is that their side effects are well described. Here is the short list.

All three are harmless and all three depend on the amount. The label prints no Supplement Facts panel, so nobody can say in advance whether a single capsule will cause any of them. Many people notice nothing at all.

The niacin flush

Niacin, in its nicotinic acid form, opens small blood vessels near the skin. The result is warmth, redness and a prickly feeling across the face, neck and chest. It usually begins within fifteen to thirty minutes and settles within an hour.

It is uncomfortable, but it is harmless, and it tends to fade with repeated use over a week or two. Taking the capsule with food reduces it. The flush is the main reason the adult upper intake for niacin from supplements is set at 35 mg a day. That limit counts everything you take, so if you also use a multivitamin or an energy drink with niacin, keep the total in mind. This article on niacin explains the limit in more detail.

The beta-alanine tingle

Beta-alanine can cause paraesthesia, a pins-and-needles feeling across the face, scalp and hands. It usually begins within about twenty minutes and passes within an hour. The sports nutrition position stand names it as the only reported side effect of beta-alanine.

In research, the tingle comes from gram doses, and it is reduced by splitting the dose into smaller portions. A capsule that holds six ingredients carries far less than that, so the tingle is unlikely here. It is described so that anyone who does feel it knows what it is and does not worry.

Stomach upset

Gram doses of arginine and citrulline can loosen the stomach. Capsule doses rarely do. The seller's instruction is to take the capsule before a meal, and that suits most people. If it sits badly on an empty stomach, take it with breakfast instead. That small change is all most people need.

Medicines to mention before you start MemoHoney

Citrulline, arginine and niacin all widen blood vessels, by different routes. Some common medicines do the same thing on purpose, so this is the one conversation worth having with a prescriber.

• Blood-pressure medicines. Two products that relax blood vessels can lower pressure more than intended.
• Nitrates. They work through the nitric oxide pathway directly, which is the clearest overlap with this formula.
• Prescription niacin and other niacin products. The 35 mg upper intake is a daily total across everything you take.

The amounts in one capsule are small, so this is a conversation rather than a warning. Show your prescriber or pharmacist all six ingredient names, not only the brand name. The who it is for page lists the groups who should check first.

When to stop taking MemoHoney

• A flush that does not fade over a couple of weeks, or one strong enough to be distressing.
• Any rash, swelling or difficulty breathing. Stop and be seen the same day.
• Light-headedness when you stand up, especially if you take a blood-pressure medicine.
• Stomach upset that does not settle when you move the capsule to mealtimes.
• Any new or worsening memory symptom. See a doctor rather than waiting on a capsule.

Stopping is simple, with nothing to taper. The 60-day guarantee covers opened bottles, so stopping early costs only the return postage. This return guide explains the steps.

How to lower the chance of side effects

• Take one capsule a day, as the label says. Never two.
• Start MemoHoney on its own, not in the same week as other new supplements.
• Take it with breakfast if you notice a flush or an unsettled stomach.
• Add up niacin across every product you take each morning.
• Write the start date on the cap, and note anything you feel in the first week.
