best L-Carnitine Base Powder Usage and Synthesis.Suplemento em Pó de Base de L-Carnitina de Alta Qualidade para Controle de Peso

L-carnitine is a vitamin-like substance that encourages the conversion of fat into energy and has no toxic side effects on the human body.Suplemento en Polvo de Base de L-Carnitina de Máxima Calidad para el Manejo del Peso Corporal

The most prominent physiological function of L-carnitine is that it acts as a carrier for fatty acid transport, transferring medium and long chain fatty acids in the form of acetyl carnitine from outside the cellular mitochondrial membrane to the inner membrane, where they are oxidised in the mitochondrial matrix to produce energy.Complément en Poudre de Base de L-Carnitine de Haute Qualité pour la Gestion Pondérale

For example, it seems to be a forklift, can shovel up fat into the fuel furnace to burn to provide energy, acted as a fat to the mitochondria of the "porter", is internationally recognised as a safe and non-toxic fat loss of nutrient-enhancing agents, the international recommendation of 1-5 grams of L-carnitine consumption is more suitable.Hochwertiges L-Carnitin Basis-Pulver als Nahrungsergänzung für das Gewichtsmanagement

It is especially suitable for people to do aerobic exercise to reduce fat, with obvious effect. L-carnitine is produced in the liver and kidney of human body and stored in muscle, semen, brain and heart.

Uses and functions of L-Carnitine Base.

L-carnitine is a newly approved food fortifier in China. It is mainly used to fortify soybean-based baby food and promote the absorption and utilisation of fat.D-type and DL-type have no nutritional value.

China stipulates that it can be used in biscuits, drinking liquids and milk beverages with the use amount of 600-3000mg/kg; in solid beverages, drinking liquids and capsules with the use amount of 250-600mg/kg; in milk powder with the use amount of 300-400mg/kg; and in infant formula food with the use amount of 70-90mg/kg (in terms of L-carnitine, 1g of tartaric acid salt is equivalent to 0.68g of L -Carnitine).

Promotes fatty acid oxidation in mitochondria and achieves other biochemical functions including acetyl buffering and maintenance of adequate coenzyme A concentrations in mitochondria under anaerobic conditions, stimulation of the tricarboxylic acid cycle, and stimulation of ATP export from mitochondria under sustained muscle exercise. Used for healthy animal growth.

Comprehensive Comparison of the L-Carnitine Family

Key Findings at a Glance

• L-Carnitine: The foundational form, offering excellent value for daily wellness.
• Acetyl-L-Carnitine: The top choice for brain and nervous system health, with strong blood-brain barrier penetration to support cognitive function and mood.
• L-Carnitine Tartrate: The king of athletic performance and recovery, featuring rapid absorption to effectively reduce muscle soreness and accelerate recovery.
• Glycerophosphatidylcarnitine: The endurance athlete's “fat booster,” enhancing fat utilization and stamina.
• Carnitine Fumarate: Focuses on cardiac energy metabolism, though less widely applied than other forms.

Product Method of Bulk L-Carnitine Base Powder.

(1) Extraction method.

Naturally occurring in a variety of meats and milks, L-carnitine can be extracted directly from L-carnitine-containing beef and cow's milk. Literature reports that 0.6g of crystalline carnitine can be obtained from 450g of beef extract and 100g of lactose powder containing 2% L-carnitine can be extracted from 56kg of cow's milk.

However, the cost of the extraction method is better and less reasonable economically.

(2) Microbial fermentation method.

Studies have shown that L-carnitine is also present in many microorganisms, and L-carnitine can be accumulated by using microorganisms such as yeast, Aspergillus, Penicillium, Rhizopus and other microorganisms liquid deep culture or solid fermentation. However, due to the complexity of strain screening, the current level of fermentation is still relatively low.

It was reported that 2% DL-carnitine was used as raw material, fermented at 25°C for 44h, and accumulated L-carnitine 0.4%.

(3) Synthetic method.

There was a patent report of DL-carnitine synthesis in 1953 in foreign countries, and there has been industrial production in the 1960s. Domestic production and application as a gastric drug was also available in 1982. Directly from DL-carnitine, L-carnitine was obtained by chemical splitting using camphoric acid, N-acetyl-D-glutamic acid or ethylbenzoyl-L-(+)tartaric acid as splitting agents.

However, D-carnitine racemisation is more difficult and cannot be recycled, and breakthroughs are still needed for industrial production.

(4) Enzymatic conversion.

This is the most researched and the most promising method. Enzymes of microbial origin can be used for selective hydrolysis and splitting. For example, Qing Nakayama used the amidase of Pseudomonas and other microorganisms to selectively hydrolyse DL-carnitine amide or carnitine nitrile, and L-carnitine with optical purity of more than 99% could be produced.

In addition, L-carnitine can be prepared by enzymatic conversion of β-dehydrocarnitine, enzymatic hydrolysis of trans-croton betaine and enzymatic hydroxylation of γ-butyl betaine.

FAQ.

Q: What is the difference between L-Carnitine Base and L-Carnitine Tartrate?

A: The main differences lie in stability and application:

L-Carnitine Base: Offers the highest purity (nearly 100%) and excellent water solubility, making it ideal for liquids, beverages, and instant powder formulations. It serves as the benchmark for calculating active L-carnitine content.

L-Carnitine L-Tartrate: A complex of L-carnitine and tartaric acid, it exhibits lower hygroscopicity and superior stability, making it more common in capsules and tablets. Its L-carnitine content is approximately 68% (meaning 1 gram of tartrate contains about 680 mg of L-carnitine).

Q: What is the recommended dosage for L-carnitine?

A: Common effective dosages range from 500 to 2000 mg/day. For athletic performance, 1000-2000 mg is typically taken 30-60 minutes before training. For weight management, 500-1000 mg can be taken with meals twice daily.

Q: Is L-carnitine safe? Are there any side effects?

A: At recommended dosages, L-carnitine is very safe for most people. Extremely high doses (e.g., over 3 grams daily) may cause mild gastrointestinal discomfort such as nausea or stomach upset.

Q: What is your minimum order quantity (MOQ) and sample policy?

A: Our standard MOQ is 10 kilograms. We offer paid samples of 1 kilogram to clients with genuine cooperation intent for your formulation testing and production evaluation.
