There are four main types of carnitine products often included in supplement products. These are glycine propionyl-l-carnitine (GPLC), ALCAR, LCLT, and L-carnitine, respectively. Although they all display similar functionalities, the use of some forms are favored over others for specific roles such as the support of cognitive function, the cardiovascular system and heart, athletic performance, weight control, and healthy aging.
Glycine propionyl-l-carnitine is created through binding of the amino acids glycine and propionyl-L-carnitine (PLC). This results in a propionyl ester, in which the carnitine has an added glycine. The GPLC form is thought to have numerous antioxidant effects and may help to support the enhancement of nitric oxide (NO) levels in the blood. It is favored by people undergoing exercise regimes as it may help to enhance training without the jitteriness symptoms sometimes reported with other forms of L-carnitine, it is thought to support healthy blood flow, and it may offer support healthy sexual support in men.
One of the main advantages of GPLC over other L-carnitine types is its relatively improved bioavailability.
GPLC plays a key role in the body’s energy production process. Propionyl-L-Carnitine is metabolized into propionyl coenzyme A and L-carnitine in the mitochondria. An organelle known as the cells energy center. Propionyl coenzyme A is further metabolized into a form that plays a role in the tricarboxylic acid cycle (TCA cycle) , which itself plays a key role in cellular aerobic respiration.
The carnitine system helps to support loss of mitochondrial function  and is important in the creation of creatine. Propionyl-L-Carnitine is thought to be more effective at supporting healthy blood flow than the L-Carnitine form.
There tends to be a lower level of circulating carnitine in vegetarians and vegans, older people, and during pregnancy.
As carnitine is naturally found in meat and dairy products it is no surprise that the natural levels of this amino acid have been reported to be much lower in both adult and children vegetarians, especially vegans [2, 3].
In pregnant women, it has been reported that carnitine concentrations are lower in the plasma; this has been suggested to be because the carnitine precursors have lower bioavailability during the gestation period .
As people reach old age (above 70), there appears to be an increase in incidence of relative carnitine deficiency . This decrease is correlated to lean body mass. Carnitine may help to support muscle function and to lower fatigue in the elderly .
As it has an effect upon antioxidant activity, GPLC helps to protect the cells from damage from free radicals. It has been reported to support the stabilization of superoxide dismutase at the blood-brain barrier from the effects of alcohol .
It has also been demonstrated to support the response of two further enzymes involved in antioxidant activities: Glutathione peroxidase, and Catalase . Further research also suggests a role for L-carnitine in the support of antioxidant status and oxidative stress responses .
When some people exercise they may get a cramping pain in the leg. This is usually a result of the arteries being obstructed, thus limiting blood flow and making it difficult to walk. GPLC may help to support against this through supporting blood flow and circulation [10, 11].
Glycine propionyl-l-carnitine may help to support healthier blood lipid profiles in humans . It has been reported that GPLC may support healthy plasma nitrate/nitrite levels in both sedentary and resistance trained men compared to the controls and placebo . The latter study revealed that short term dosage values of 3 g per day helped some men to improve NO levels in the plasma. Nitric oxide has been put forward as being associated with muscle growth, strength, and performance in numerous studies [13, 14, 15, 16].
GPLC may help to support power output during sprinting. When resistance trained athletes were provided an acute supplement of it before performing Wingate cycle sprints there was an observable support of anaerobic work capacity, peak power production, and lactate accumulation and clearance compared to the baseline [17, 18]. The improved sporting performance, reported over several weeks of testing, appears to be dosage dependent.
As well as being associated with muscle energy, the signaling molecule NO has been linked to supporting healthy sexual support in men most likely through its role as a vascular regulator . Markers associated with NO and lipid peroxidation may be elevated through supplementation with GPLC in some men .
The combination of Acetyl-L-Carnitine and PLC has been reported as supporting mood, fatigue, and healthy sexual support in the elderly .

I am a vegetarian; can I take your supplements?
Yes, our products are suitable for vegetarians. This is especially relevant in the case of Glycine propionyl-l-carnitine, as vegetarians and vegans are reported to have much lower natural levels of l-carnitine than omnivores.
Are there any side effects associated with taking L-carnitine?
The most common minor side effects are diarrhea, headache, nausea, vomiting, and stomach cramps. There are a few more moderate side-effects, such as faster heartbeat, fever, and raised blood pressure. For a more in-depth look at possible side effects please see this article: [https://www.drugs.com/sfx/l-carnitine-side-effects.html].
As with any drug or medication, it is recommended that you cease use and consult your doctor or medical professional at the first instance, if you see any unwanted effects when taking GPLP dietary supplements.
What is Glycine propionyl L-carnitine (GPLC)?
It is a combination of the amino acids glycine and PLC. L-carnitine is produced by the body and can be readily converted into GPLC or ALCAR.
Who is most susceptible to GPLC deficiency?
Vegetarians, the elderly, pregnant women, and those suffering from conditions that affect blood glucose levels or the arteries [21–23].
Is it good for the treatment of male menopause?
Many men take GPLC to help support problems associated with fatigue and sexual performance.
In addition to GPLC, what other forms are there, and what are some of the other names for it / them?
Acetyl-L Carnitine HCL (also known as ALCAR, often taken for its supposed brain boosting effects); Levocarnitine; (R)-Carnitine; Carnitor; and Vitamin BT. The IUPAC name of L-Carnitine is (3R)-3-hydroxy-4(trimethylazaniumyl)butanoate.
What is L-carnitine and L-tartrate?
L-tartrate is an antioxidant. Carnitine may help to support the transport of toxic products from the, and fatty acids to the, mitochondria.
Does it have any benefits for bodybuilding?
How many minutes before exercise for a significant effect?
Many people take it 15 to 30 minutes before exercising, as this is thought to produce a greater benefit.
GPLC vs PLC vs ALCAR vs LCLT?
See this article on bodybuilding.com for findings on this group [http://forum.bodybuilding.com/showthread.php?t=121355501]
What is the use of L carnitine?
It plays a role in support energy production and supporting enzymes with antioxidant properties.
How much L-carnitine should I take?
1 g is thought to be effective. There are reports that some of the health benefits that it may support are dosage dependent, with higher dosages of up to 3 to 4.5 grams noted to be used in some clinical trials.
Is carnitine a stimulant?
It may have beneficial stimulatory effects as a result of its role in energy production via the transport of fatty acids.
What foods are high in L carnitine?
If you want to include more carnitine in your diet than you may need to increase your consumption of red meat and dairy products. Other carnitine rich foods include greens, sprouts, buckwheat, and rice bran.
How many servings are there in a container of VitaMonk GlycoTrax™
There are 30 servings per tub (the serving size is two capsules). Each capsule contains 500mg of GPLC. Our products are gluten free and are made in the USA.
