Ph Buffered Creatine Alkaline

Also known as: Creatine monohydrate, pH-buffered creatine, Kre-Alkalyn, methylguanidinoacetic acid, Creatine

Overview

pH Buffered Creatine Alkaline, often marketed under brand names like Kre-Alkalyn, is a modified form of creatine monohydrate. It is chemically buffered to a higher pH level, which manufacturers claim enhances its stability in acidic environments, such as the stomach, and reduces its conversion into the inactive byproduct creatinine. Creatine itself is an amino acid derivative naturally found in meat and fish, and is widely supplemented to increase muscle creatine stores. The primary goal of buffered creatine is to improve high-intensity exercise performance, increase strength, and promote lean muscle mass, similar to standard creatine monohydrate. While creatine monohydrate is extensively researched and proven effective, buffered forms have fewer studies, with mixed evidence regarding their claimed superiority or reduced side effects.

Benefits

Creatine monohydrate reliably increases muscle creatine content, leading to improvements in strength, power, and anaerobic capacity. Buffered creatine (e.g., Kre-Alkalyn) claims to offer similar benefits, potentially at lower doses and with fewer gastrointestinal side effects like bloating. However, current high-quality research, such as a randomized controlled trial by Spillane et al. (2012), indicates no significant superiority of buffered creatine over creatine monohydrate in terms of muscle creatine retention, strength gains, or anaerobic capacity improvements. Resistance-trained athletes and individuals engaged in high-intensity exercise are the primary beneficiaries. Creatine monohydrate typically increases muscle creatine by 20-40% and strength gains by 5-15% over several weeks. While buffered creatine shows similar magnitudes of effect, it does not demonstrate a clear advantage. Benefits usually become apparent after about one week of a loading phase and continue with consistent maintenance dosing. Some in vitro studies suggest potential cytoprotective effects, but these lack clinical relevance and robust human data.

How it works

Creatine primarily functions by enhancing the creatine phosphate system, which is crucial for rapidly replenishing adenosine triphosphate (ATP) during high-intensity, short-duration exercise. Within skeletal muscle cells, creatine is phosphorylated to phosphocreatine, which then donates a phosphate group to adenosine diphosphate (ADP) to regenerate ATP, the body's primary energy currency. This mechanism supports sustained power output during activities like weightlifting or sprinting. Buffered creatine is designed to maintain a higher pH, theoretically reducing its degradation to creatinine in the acidic environment of the stomach. This aims to ensure more creatine reaches the muscles intact. While creatine monohydrate is nearly 100% bioavailable, the buffering in alkaline forms is intended to prevent premature breakdown, though clinical studies suggest similar overall bioavailability and efficacy.

Side effects

Creatine monohydrate is generally considered safe for healthy individuals when taken at recommended doses, and buffered creatine appears to share a similar safety profile. The most commonly reported side effects are minor gastrointestinal discomfort and bloating, although manufacturers of buffered forms claim these are less frequent. However, controlled studies have not consistently shown a significant reduction in these side effects with buffered creatine compared to monohydrate. There are no reports of serious adverse events in healthy individuals. Significant drug interactions are not known. Individuals with pre-existing kidney disease or impaired renal function should avoid creatine supplementation unless under strict medical supervision, as creatine is metabolized and excreted by the kidneys. Data on the safety and efficacy of creatine in special populations, such as children, pregnant women, or those with specific clinical conditions, are limited, and its use in these groups is generally not recommended without professional medical advice.

Dosage

For creatine monohydrate, a common approach involves a loading phase of 20 grams per day for 5-7 days, followed by a maintenance dose of 3-5 grams per day. While buffered creatine is often marketed with claims of effectiveness at lower doses, typically ranging from 1.5 to 5 grams per day, these lower doses have not been conclusively proven to be superior or equally effective as standard creatine monohydrate doses in clinical trials. The maximum safe dose for short-term loading is up to 20 grams per day, with long-term safety established at 3-5 grams per day. The timing of creatine intake is not critical; consistent daily dosing is more important for maintaining muscle saturation. Buffered creatine is specifically formulated to be more stable in solution and stomach acid, aiming to reduce degradation. While co-ingestion with carbohydrates can enhance creatine uptake, it is not essential for its effectiveness.

FAQs

Is buffered creatine better than creatine monohydrate?

Current scientific evidence does not support the superiority of buffered creatine over creatine monohydrate in terms of efficacy for muscle gain or performance enhancement.

Does buffered creatine reduce side effects like bloating?

While some anecdotal reports suggest less bloating, controlled studies have not consistently shown a significant reduction in side effects compared to creatine monohydrate.

How quickly does buffered creatine work?

Buffered creatine has a similar time course of action to creatine monohydrate, with benefits typically appearing after about one week of consistent use.

Is a loading phase necessary for buffered creatine?

A loading phase can accelerate muscle saturation, but it is not strictly mandatory; consistent daily dosing will eventually achieve similar results.
