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

By Mark Robinson


If you have taken a pre-workout supplement recently, it is very likely that you've experienced this itchy/tingly feeling on your skin. This sensation is called "Paresthesia", and is actually harmless at the doses pre-workouts provide. It can be quite mild at lower doses, but can also be pretty uncomfortable at higher ones. Some people enjoy this tingly feeling because it helps them to know that the supplement they've taken is working. Some people don't feel it at all. And yet others find it way too uncomfortable to cope with, either due to a higher sensitivity, dry skin, or other condition.

How does your pre-workout supplement do this? Which ingredient(s) in specific?

Beta Alanine (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.

Can I avoid this feeling?

The tingling sensation is just unbearable for some people. But the problem is, a huge majority of the products contain at least 1 or both of these itch inducers. If this is you, your best way to approach these will be at a turtle speed. Start a smaller than the recommended scoop size, and slowly work your way up as you feel comfortable enough to do so.
