Pre-Workout Supplement Tips: Which Ingredients Are Making Your Skin Crawl?

By Mark Robinson

If you've ever felt that tingly or itchy sensation after drinking your pre-workout supplement, you've experienced something called "Paresthesia". This feeling is actually harmless to us, but can come as quite a surprise if you're not expecting it. If taking a high dose, the feeling can be pretty uncomfortable. And at lowers doses, it will be fairly mild. Some users report that they like the feeling because it makes it clear to them that the supplement is working. But others, perhaps due to a higher sensitivity, or too high a dose, the feeling can be far too uncomfortable to deal with.

What is in your pre-workout that does this? And why?

Beta-Alanine (a.k.a Carnosyn)

Beta-Alanine is a non-essential amino acid naturally found in our bodies. In our muscles, it binds with histidine to form muscle carnosine (Hence the brand name Carnosyn). Muscle carnosine is the main buffering agent that works in our muscles to fight off, or neutralize the ions(hydronium) that lead to muscle fatigue and failure. By upping the amount of carnosine in our muscles, we can benefit from an increase in endurance at high level performance, and accelerated recovery. The tingling sensation comes from the nerves beneath our skin being activated at a higher rate, due to the beta alanine attaching itself to them.

Niacin (Vit. B3)

All the components of the B-Vitamin family mainly work to process the food we eat. Their primary function is tied to the production of energy within us. The itchy feeling referred to in regards to Niacin is called a "flush". This sensation comes up due to the niacin widening some of our smaller blood vessels, also known as capillaries, close to the surface of our skin.

Do I Have To Endure The Discomfort?

Some people can't stand this itchy feeling and give up entirely. It can be hard to avoid it however because a large majority contain the two culprit ingredients. The best way to start using one of these supplements, is with great care. Start off small, even a half dose, and see how it makes you feel. If you begin to feel more comfortable with it, then you can increase the dose.
