Beta-Alanine: What’s the Proper Dosage?

Beta-Alanine — What’s the Proper Dosage?

Ask any professional athlete, and they’ll tell you proper dosing is critical to the efficacy of a pre-workout supplement — and to your overall physical performance.

Proper dosing also helps prevent paresthesia, an uncomfortable but harmless itching and tingling of the skin that’s common after taking high quantities of beta-alanine. (This reaction may vary depending upon the individual, the dosage amount, and food intake prior to supplementing.)

Proper Dosing (and Stacking) of Beta-Alanine

First, you should opt for a supplement that contains a fully tested, branded ingredient, such as CarnoSyn®, as opposed to generic beta-alanine. The fact is, with generic beta-alanine, there’s no real way of knowing if it is safe and effective–or that you’re getting the proper dose. Only CarnoSyn® is proven to improve athletic performance. In a 10-week study on high-intensity cyclists, supplementation with CarnoSyn® led to an overall 80% muscle carnosine increase. This was after an initial 58.8% increase at 4 weeks, followed by improved capacity and increased muscle carnosine thereafter.[1]

When it comes to proper dosing, a minimum of 90 grams over a period of 28 days is ideal. To amplify muscle performance, 179 grams over a 28-day period is recommended. These dosing regimens range on average from 3.2 to 6.4 grams per day. The higher the dose, the higher the carnosine retention, resulting in enhanced peak performance.

For athletes who choose to take the maximum dose, it doesn’t have to be taken all at once. Many athletes do what’s called stacking. This can be done via a pre-workout or post-workout, a standalone product in a single dose or multiple doses, or as a combination of pre/post formulations and standalone products.

What is a Loading Period?

Many athletes choose to obtain optimum beta-alanine intake by employing a “loading” phase or loading period into their workout regimen. A loading period is required to experience the benefits of supplementation. According to The International Society of Sports Nutrition (ISSN), supplementing with beta-alanine for a minimum of two to four weeks can “improve exercise performance, with more pronounced effects in open end-point tasks/time trials lasting one to four minutes in duration.”[2]

After the loading period, it’s important to take beta-alanine daily to achieve proven results–not just on workout days. Some athletes choose to reduce their beta-alanine intake at that point and enter into what’s referred to as a “maintenance” phase. Other athletes prefer to vary their dosage amount based on their daily activity–taking higher doses on training days, for example.

Instant Release vs. Sustained Release

There are two ways to get results with CarnoSyn® beta-alanine: via instant release and sustained release formulas. SR CarnoSyn® offers the same benefits as instant release CarnoSyn®, but in an advanced delivery system allowing higher dosing levels. Sustained-release properties also help minimize paresthesia and extend retention. Using instant release and sustained release in tandem gives athletes the ability to stack their dosing for higher quantities of beta-alanine and greater performance gains. For example, in a study comparing sustained-release and instant-release, SR CarnoSyn® demonstrated a 16.4% greater increase in muscle carnosine than instant beta-alanine.[3]

CarnoSyn® beta-alanine can be used in a number of dosage forms: powders, tablets, capsules, stick packets, chewables/lozenges, and more. SR CarnoSyn® is a patented ingredient available in tablet form. It contains the only beta-alanine that has successfully obtained FDA NDI status.

CarnoSyn® beta-alanine is available in two different forms—instant release and sustained release—offering two ways to dose. SR CarnoSyn® offers the same benefits as instant release CarnoSyn®, but in an advanced delivery system that allows for increased dosing for better results. When used in tandem, the combination of instant release and sustained release gives athletes the ability to stack their dosing for higher quantities of beta-alanine and even more performance gains.
