Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creatine formulations face stability and solubility issues in acidic environments of the stomach and intestines, leading to rapid degradation into creatinine, resulting in low absorbance and potential digestive problems when ingested, necessitating high doses to achieve desired muscle levels.
Innovation Solution
A creatine formulation combining creatine hydrochloride (creatine.HCl) with polyethylene glycol (PEG), coated with an enteric coating, which enhances stability and absorption, allowing for lower effective dosages and reduced digestive issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If creatine monohydrate is used as a dietary supplement, then skeletal muscle uptake is enhanced, but stability in the acidic environment of the stomach is poor leading to rapid degradation into creatinine
Solution Approach 1:
The patent uses polyethylene glycol (PEG) as an intermediary substance that forms a stable complex with creatine. This PEG-creatine complex acts as a mediator that protects creatine from degradation in the acidic stomach environment, allowing it to pass through the gastrointestinal tract intact and be absorbed in the lower intestines where pH is more favorable.
Solution Approach 2:
The patent changes the chemical parameters of creatine by forming a complex with PEG, which alters the stability characteristics of creatine. Additionally, the enteric coating changes the environmental parameters (pH exposure) by protecting the creatine-PEG complex from stomach acid and allowing release in the more neutral environment of the lower intestines.
2Ease of operation
If creatine monohydrate is dissolved in fruit juices or acidic liquids to improve solubility, then dissolution is enhanced, but degradation to creatinine is promoted
Solution Approach 1:
The patent creates a composite material system consisting of creatine, polyethylene glycol, and enteric coating materials. This composite structure provides both the solubility benefits of PEG and the protective function of the enteric coating, eliminating the need to dissolve creatine in acidic liquids while maintaining enhanced solubility and stability.
3Quantity of substance
If high doses of creatine are ingested to compensate for degradation loss, then desired muscle levels are achieved, but digestive problems occur due to creatinine presence
Solution Approach 1:
The patent converts the harmful effect of stomach acid (which normally degrades creatine) into a beneficial selection mechanism by using enteric coating. The coating resists stomach acid, allowing the creatine-PEG complex to pass through unchanged, and only releases in the lower intestines where the environment is more favorable for creatine stability and absorption, thereby eliminating creatinine formation from acid degradation.
4Ease of manufacture
If polyethylene glycol esters are synthesized by reacting creatine with PEG in the presence of acid catalysts, then ester formation is attempted, but degradation to creatinine occurs and stability in low pH environments is not achieved
Solution Approach 1:
The patent extracts the problematic acid catalyst step from the synthesis process. Instead of using acid catalysts that cause degradation, the invention uses PEG to form a complex with creatine under milder conditions, and then applies enteric coating to protect the product from acidic environments, thereby achieving stability without the harmful acid catalysis step.
