Creatine Decanoate
Also known as: Creatine ester decanoate, Creatine decanoate
Overview
Creatine decanoate is a synthetic derivative of creatine, specifically a creatine molecule esterified with decanoic acid, a 10-carbon medium-chain fatty acid. Unlike naturally occurring creatine, creatine decanoate is synthesized for supplementation purposes. It is marketed primarily for enhancing muscle mass, strength, and exercise performance, similar to creatine monohydrate. The esterification aims to increase its lipophilicity (fat solubility), theoretically improving its absorption and cellular uptake compared to creatine monohydrate. However, direct peer-reviewed research on creatine decanoate is extremely limited, with no high-quality randomized controlled trials or systematic reviews available to substantiate these claims. Most research on creatine's benefits pertains to creatine monohydrate.
Benefits
The benefits commonly associated with creatine supplementation, such as increased muscle mass, strength, and improved exercise performance, are primarily derived from studies on creatine monohydrate. Creatine monohydrate has also shown potential neuroprotective and cognitive benefits, including improvements in memory, attention, and processing speed, particularly in populations like older adults, athletes, and those with neurodegenerative diseases. Meta-analyses indicate small to moderate effect sizes for muscle hypertrophy and cognitive improvements with creatine monohydrate, with benefits typically appearing after several weeks of consistent supplementation (e.g., 4 weeks or more). However, these well-established findings for creatine monohydrate cannot be directly extrapolated to creatine decanoate due to the complete lack of specific, high-quality human clinical trials on creatine decanoate itself. Therefore, any claims of benefits for creatine decanoate are currently unsubstantiated by scientific evidence.
How it works
The proposed mechanism of action for creatine decanoate is based on the known pathways of creatine. Creatine primarily functions by increasing phosphocreatine stores within muscle and brain cells. This enhanced phosphocreatine pool supports the rapid regeneration of adenosine triphosphate (ATP), the body's primary energy currency, particularly during high-intensity, short-duration activities. This process involves the creatine kinase system and plays a crucial role in mitochondrial energy metabolism. While creatine monohydrate is absorbed via active transport in the gut, creatine esters like decanoate are hypothesized to possess improved lipophilicity and membrane permeability due to their fat-soluble component. This theoretical enhancement in absorption and bioavailability, however, remains unproven in human studies for creatine decanoate.
Side effects
The overall safety profile of creatine decanoate is largely unknown due to the absence of specific research. Creatine monohydrate, in contrast, is generally considered safe with minimal side effects, primarily gastrointestinal discomfort and weight gain due to water retention. Given the lack of data, it is not possible to definitively list common side effects, drug interactions, or contraindications for creatine decanoate. For creatine monohydrate, caution is advised in individuals with pre-existing renal impairment, though this is not definitively established for creatine decanoate. As a general precaution, pregnant or breastfeeding women, children, and individuals with kidney disease should consult healthcare providers before considering any creatine supplement, including creatine decanoate, due to the unknown safety profile of this specific derivative.
Dosage
There are no established dosing guidelines for creatine decanoate derived from peer-reviewed scientific studies. Dosage recommendations for creatine are based on extensive research on creatine monohydrate, which typically involves a loading phase of 20 grams per day for 5-7 days, followed by a maintenance dose of 3-5 grams per day. Creatine monohydrate is often timed around exercise (pre- or post-workout), and its absorption can be enhanced when consumed with carbohydrates. However, none of these guidelines or absorption factors are applicable or known for creatine decanoate due to the absence of specific research. Without scientific evidence, any suggested dosage for creatine decanoate is speculative and lacks empirical support.
FAQs
Is creatine decanoate more effective than monohydrate?
No high-quality evidence supports the superiority of creatine decanoate over creatine monohydrate. Claims of improved efficacy are theoretical or from manufacturer data, lacking independent scientific validation.
Is creatine decanoate safe?
The safety profile of creatine decanoate is largely unknown due to a lack of specific research. Creatine monohydrate is well-studied and generally considered safe, but this does not extend to decanoate.
How quickly does creatine decanoate work?
The onset of effects for creatine decanoate is unknown. For creatine monohydrate, benefits typically appear after several weeks of consistent supplementation.
Can creatine decanoate improve cognition?
While creatine monohydrate has shown some cognitive benefits, there is no scientific data or research to suggest that creatine decanoate can improve cognitive function.

- https://pubmed.ncbi.nlm.nih.gov/39070254/ – This systematic review and meta-analysis by Xu et al. (2024) investigated the effects of creatine monohydrate on cognitive function in adults, analyzing data from 16 randomized controlled trials. The study found significant improvements in memory, attention, and processing speed with creatine monohydrate supplementation. This research highlights the cognitive benefits of creatine monohydrate but provides no information or data regarding creatine decanoate.

It details the methodology and findings regarding creatine monohydrate's impact on cognitive function, confirming significant improvements in various cognitive domains. The study reinforces the evidence for creatine monohydrate's benefits but does not include any research on creatine decanoate.
- https://pubmed.ncbi.nlm.nih.gov/37432300/ – This systematic review and meta-analysis (2023) focused on creatine supplementation combined with resistance training, analyzing 10 randomized controlled trials. The findings indicated small but significant increases in muscle hypertrophy, as measured by imaging techniques like MRI, CT, and ultrasound. This evidence supports the efficacy of creatine, specifically creatine monohydrate, for muscle growth but does not provide any data on creatine decanoate.
