Betaprime
Also known as: Beta-Alanine, β-Alanine
Overview
Beta-Alanine is a non-essential amino acid primarily found in foods such as meat, fish, and poultry. It is recognized for its role in enhancing athletic performance, particularly during high-intensity, short-duration exercises by increasing muscle carnosine levels. Carnosine acts as a buffer against lactic acid accumulation, thereby delaying fatigue. The research surrounding Beta-Alanine is robust, featuring numerous studies and meta-analyses which substantiate its effects in athletic performance. Typical dietary intake is low, which is why supplementation is common for those looking to improve their exercise capacity. Beta-Alanine is available in various forms, including capsules, tablets, and powders, with the latter often preferred for dosing ease.
Benefits
Beta-Alanine supplementation is evidenced to significantly improve exercise capacity and performance in high-intensity exercises lasting between 0.5 to 10 minutes, with a meta-analysis reporting a significant effect size of 0.18 (95% CI 0.08 to 0.28). More pronounced benefits tend to be seen in exercise capacity (effect size 0.4998) compared to overall performance (effect size 0.1078). It is particularly beneficial for athletes and individuals engaging in short-duration, high-intensity activities. However, there is limited evidence supporting its effectiveness in improving body composition indices (body mass or fat percentage). Benefits typically manifest after several weeks of consistent supplementation, highlighting the importance of ongoing use for optimal results.
How it works
Beta-Alanine functions by combining with histidine to form carnosine in muscle tissues. Carnosine acts as a buffer to prevent the accumulation of lactic acid during exercise, which delays the onset of muscle fatigue. This buffering capacity is particularly beneficial during high-intensity activities, enhancing performance by enabling longer durations before fatigue sets in. The supplementation of Beta-Alanine has been shown to significantly increase muscle carnosine concentrations, further amplifying its ergogenic effects.
Side effects
Beta-Alanine is generally considered safe when used within recommended dosages. The most common side effect is paresthesia, characterized by a tingling sensation in the skin, which is dose-dependent and usually temporary. Other side effects are rare, with no significant adverse effects reported in well-controlled studies. There are currently no known significant drug interactions or established contraindications for Beta-Alanine. However, pregnant or breastfeeding women are advised to consult healthcare providers prior to use due to limited safety data in these populations. Overall, safety is highlighted when the supplement is taken at recommended dosages.
Dosage
The minimum effective dose of Beta-Alanine is generally 2-4 grams per day, with optimal doses ranging from 4 to 6 grams. It is recommended to take these dosages in divided doses to mitigate potential side effects like paresthesia. While no maximum safe dose is well established, exceeding 6 grams daily is not typically suggested. Timing is flexible; it can be taken at any point during the day, though pre- and post-exercise dosing is common to maximize performance benefits. Beta-Alanine is available in multiple forms, including powders, which are often favored for easier dosing. Food intake does not significantly affect its absorption.
