After taking a pre-workout, you may experience an unexpected tingling, itching, or warm flush. This sensation is particularly noticeable if it spreads to your face, arms, or chest. Even though it could seem strange, it’s not always an indication of a problem. These feelings are typically associated with particular substances that are frequently included in pre-workout preparations, causing transient nerve or blood vessel reactions rather than dangerous allergic reactions.
An anesthesiologist and interventional pain medicine specialist is explaining why taking pre-workout supplements might cause tingling sensations, sometimes known as the “pins-and-needles effect.” You’re not dreaming if you’ve ever felt your arms or face humming after a preworkout; there is actual physiology involved. He lists the following explanations:
Alanine beta-alanine
According to Dr., beta-alanine, a prevalent ingredient in many formulations, is frequently associated with the tingling or “pins and needles” sensation that some people get after taking pre-workout supplements. It causes the pins-and-needles sensation known as paresthesia by activating receptors on your skin’s sensory nerves, he adds. It’s not harmful, but it’s unmistakable.
Vitamin B3, or niacin
Niacin, often known as vitamin B3, is another chemical found in some pre-workout products that may contribute to the tingling sensation as well as facial flushing and redness. “In higher doses, niacin triggers a normal flush response,” the doctor emphasizes. Particularly in the face and upper torso, enlarged blood vessels cause warmth, redness, and mild irritation. Usually, these feelings reach their climax in the first hour and then go away on their own.
Artificial flavors and colors
Some sensitive people may experience irritation when certain artificial flavors and colors are added to pre-workout solutions. “For some people, if they are sensitive to certain additives, artificial colors, or flavorings, pre-workouts can also trigger itching,” the doctor says.
How can this effect be differentiated from allergies?
Dr. emphasizes that although flushing from niacin or tingling from beta-alanine are not harmful, it’s crucial to differentiate these from allergic reactions, which can be concerning. He highlights the following symptoms: “Hives, swelling, tightness in the throat, or difficulty breathing are concerning signs that indicate an allergic reaction rather than the usual effects of pre-workout ingredients.”
