1. Description
Chemical Properties: Cardiogen, chemically designated as (±)-3-hydroxy-4-trimethylammoniobutanoic acid, belongs to the class of quaternary ammonium compounds. Its molecular structure incorporates hydroxyl and ammonium functional groups, with a molecular weight of 161.21 Da. Its primary target is carnitine palmitoyltransferase (CPTⅠ/CPTⅡ) on the mitochondrial membrane. Acting as a “carrier” for fatty acid transport across the mitochondrial membrane, it mediates the entry of long-chain fatty acids into mitochondria for β-oxidation. Chemically stable, it resists hydrolysis within a pH range of 3.0–9.0 and exhibits strong thermal stability (stable below 100°C). It demonstrates excellent compatibility with active ingredients such as caffeine, conjugated linoleic acid, and B vitamins, with no significant contraindications.
Physical Properties: Cardiogen appears as a white crystalline powder or colorless transparent crystals at room temperature. It is odorless, has a slightly bitter taste, and is highly hygroscopic. Highly water-soluble (solubility ≥100 mg/mL), rapidly dissolves in aqueous media such as pure water, saline, glycerin, and propylene glycol; slightly soluble in ethanol; insoluble in non-polar solvents like ether and chloroform. Store in a sealed container in a cool, dry place (avoid moisture). Industrial-grade / Food-grade / Pharmaceutical-grade products all have a purity ≥98% (HPLC testing). Impurities such as heavy metals (lead, mercury, arsenic ≤0.1 ppm), chlorides, sulfates, etc., meet corresponding standards. No endotoxin residue (pharmaceutical-grade).
Source and Preparation: Natural carnitine predominantly exists as the L-form in animal muscle, liver, and dairy products. DL-carnitine is a synthetic racemic mixture (1:1 blend of L-carnitine and D-carnitine) L-carnitine in a 1:1 ratio). It is prepared via chemical synthesis—using γ-butyrolactone, trimethylamine, chloroacetic acid, and other raw materials, undergoing epoxidation, amination, hydrolysis, and other reactions, followed by recrystallization purification to obtain a high-purity product. The synthesis process strictly controls reaction conditions to ensure uniform racemic ratio. Product structure is verified via optical rotation testing (specific rotation [α]₂₀ᴰ is ±0°) and infrared spectroscopy (IR), with no residual synthetic byproducts.
2. Application
1. Health Intervention and Sports Nutrition Sector (Core Applications)
Fat Loss & Body Sculpting Products: Cardiogen targets individuals with simple obesity, localized fat accumulation (waist/abdomen, thighs), and postpartum weight loss. Develops fat-reducing dietary supplements, meal replacement powders, and localized sculpting gels. Formulation Logic: DL-Carnitine (5%-15% concentration) + Caffeine (1%-2%) + Conjugated Linoleic Acid (2%-5%). DL-Carnitine promotes fat breakdown for energy, caffeine accelerates metabolism, and CLA inhibits fat synthesis—synergistically achieving “fat burning + fat control.”
Sports Nutrition Supplements: Targeted at fitness enthusiasts and athletes for developing energy supplements and endurance-boosting oral solutions. Formulation Logic: DL-carnitine (10%-20%) + creatine (5%-10%) + B vitamins (1%-2%). DL-carnitine enhances fatty acid oxidation efficiency, reduces glycogen depletion, prolongs exercise endurance, and accelerates post-workout fatigue recovery.
Anti-Fatigue Health Products: Targeting individuals experiencing energy depletion and fatigue due to late nights, high stress, or aging. Used for developing oral health liquids and sublingual tablets. Formulation Logic: DL-carnitine (5%-8%) + Coenzyme Q10 (0.5%-1%) + Zinc gluconate (0.1%-0.2%) to improve cellular energy metabolism and alleviate muscle soreness and mental fatigue.
2. Pharmaceutical Adjunct Therapy Applications
Fatty Liver Adjunct Therapy: Cardiogen is used to develop fatty liver adjunct formulations (oral capsules, granules) suitable for non-alcoholic and alcoholic fatty liver conditions. It promotes hepatic fat transport and breakdown, reduces triglyceride accumulation, and improves hepatic steatosis. Often combined with silymarin and vitamin E to enhance liver protection.
Cardiovascular Disease Intervention Support: Used as adjunctive therapy for coronary heart disease and heart failure. Improves myocardial energy supply (by promoting fatty acid oxidation to generate ATP), mitigates myocardial ischemia-hypoxia damage, and simultaneously lowers blood triglyceride levels to assist lipid regulation. Suitable for patients with hyperlipidemia and cardiovascular diseases.
Renal Dialysis Support Care: Used for nutritional supplementation in end-stage renal disease dialysis patients. Carnitine is prone to depletion during dialysis; supplementing with DL-carnitine can alleviate dialysis-related complications such as muscle cramps, fatigue, and anemia, thereby improving patient quality of life.
3. Beauty and Body Care Sector
Body Contouring Products: Cardiogen targets individuals with abdominal, thigh, and buttock fat accumulation and skin laxity. It is used in developing contouring creams, slimming serums, and massage gels. Formulated at 3%-5% concentration, it is blended with capsaicin derivatives (0.01%-0.03%) + Menthol (0.1%-0.2%) to promote localized fat metabolism, enhance skin firmness, and alleviate obesity-induced skin laxity.
Scalp Care Products: For hair loss and dry hair caused by insufficient follicular energy and imbalanced sebum secretion, develop anti-hair loss shampoos and scalp repair serums. Addition concentration: 1%-2%, blended with biotin (0.01%-0.02%) + caffeine (0.5%-1%) to improve follicular energy supply, reduce fragile hair root shedding, and strengthen hair shaft resilience.
3. Main Efficacy
Core Function: Enhanced Fatty Acid Transport and Energy Metabolism
Mechanism: DL-carnitine acts as a “fatty acid carrier.” By binding with carnitine palmitoyltransferase (CPTⅠ/CPTⅡ), it mediates the transport of long-chain fatty acids across the mitochondrial double membrane into the mitochondrial matrix for β-oxidation. This process generates ATP (the cellular energy currency). Simultaneously, it facilitates the entry of fatty acid metabolism intermediates (acetyl-CoA) into the tricarboxylic acid (TCA) cycle, enhancing energy conversion efficiency to fundamentally address fat accumulation and cellular energy deficiency.
Fat Reduction, Body Contouring, and Body Fat Regulation
Mechanism: Cardiogen accelerates fat breakdown for energy production, reducing accumulation of white adipose tissue (storage fat), particularly in localized areas like the waist, abdomen, and thighs. It simultaneously elevates basal metabolic rate and decreases post-exercise fat synthesis, making it suitable for fat loss and weight management scenarios. Continuous use reduces body fat percentage, waist circumference, and hip circumference.
Liver Protection and Blood Lipid Regulation Effects
Mechanism: Cardiogen promotes the transport and breakdown of hepatic fat (triglycerides), reducing hepatic steatosis and improving fatty liver symptoms. It also enhances the metabolism of blood triglycerides and LDL cholesterol while elevating HDL cholesterol levels, thereby assisting in lipid balance regulation and lowering cardiovascular disease risk.
Exercise Performance and Fatigue Resistance
Mechanism: Prioritizes fat mobilization for energy during exercise, reducing glycogen depletion and extending endurance (by over 30%); accelerates post-exercise lactic acid metabolism to alleviate muscle soreness and promote recovery; enhances energy supply to cardiac and skeletal muscles, improving fatigue and weakness.
Safety Advantages
As a carnitine compound, it exhibits exceptional biocompatibility. The human body naturally synthesizes small amounts of carnitine, making exogenous supplementation non-immunogenic and unlikely to trigger allergic reactions. Acute/chronic toxicity studies confirm no significant side effects at oral doses ≤5 g/kg, with only a minority experiencing mild gastrointestinal discomfort (e.g., nausea, diarrhea), typically transient. High regulatory compliance: Listed in China's Food Additive Standards, Catalog of Cosmetic Ingredients in Use, and pharmaceutical excipient standards, suitable for diverse applications including food, cosmetics, and pharmaceuticals.
