Take 1 capsule with meals (morning and noon) and 1 capsule 1 hour before, during and after working out.

Why choose Nutrimuscle's Carnitine Carnipure®?

Nutrimuscle only uses the purest form of Carnitine. 

Just as Creapure® represents the quality benchmark for creatine, it's L-Carnipure® that represents the ultimate in quality when it comes to carnitine.

Pharmaceutical-grade L-Carnipure® is produced by the Swiss group Lonza and contains:

  • Zero impurities
  • No traces of D-carnitine (a synthetic form of carnitine not found naturally that inhibits the absorption of L-carnitine)
  • No GMOs
  • No allergenic substances

Because of its purity, L-Carnipure® is the most widely used carnitine in medical studies. This carnitine in particular is referenced in medical publications concerning sports performance, health, and weight loss.

What is L-carnitine?

Carnitine plays an essential role in fat oxidation: it facilitates the transportation of lipid molecules within tissues so that they can be burned.

Carnipure® L-carnitine is composed of L-carnitine tartrate. Carnitine is a molecule that the liver and kidneys synthesise from two amino acids (lysine and methionine), three vitamins (niacin, B6, and C), and iron.

Carnitine plays a key role in energy metabolism. This is why supplementation is used to lose weight as well as for recovery and to fight against fatigue.

What are the benefits of Nutrimuscle's Carnitine Carnipure®?

A significant effect on muscles

Carnitine promotes muscle oxygenation and saves oxygen during exercise. It also accelerates muscle recovery and growth and increases the density of testosterone receptors on the muscles.

Fat-burning properties

Carnitine plays an essential role in fat oxidation. It facilitates the transportation of lipid molecules within tissues so that they can be burned.

Antioxidant properties

L-carnitine increases the body's antioxidant defense capacities by 30% (23). It acts indirectly by increasing the capacities of the cellular enzymes that produce our own antioxidants.

Composition

Ingredients of Nutrimuscle Carnitine Carnipure®

L-carnitine Carnipure® powder:

  • L-carnitine tartrate Carnipure.

L-carnitine Carnipure® in capsules:

  • Beef gelatin capsule.

In order to protect L-carnitine from degradation, it is generally added another molecule.

So when you use 1g of carnitine supplement, there isn't really 1g of L-carnitine in it, because part of the supplement is made up of this second protective molecule.

But are you being told what the actual percentage of L-carnitine is in the product?

Usually, this topic is not discussed to suggest a higher dosage than it actually is.

Nutrimuscle plays transparency by specifying precisely the content of its supplements:

L-carnitine Carnipure® contains 68% L-carnitine and 32% tartaric acid (an antioxidant that prevents carnitine from absorbing water molecules in the air).

In 1 g of Carnipure® L-carnitine, there are therefore 680 mg of L-carnitine and 320 mg of tartaric acid.

Usage tips

Who is Carnipure® L-carnitine for?

Carnipure® L-carnitine is for:

  • Athletes, for its significant benefits on the muscles, both during and after exertion
  • Inactive people, for its fat-burning effects and antioxidant properties

When should I take Carnipure® L-carnitine?

During meals

It is important to take your Carnipure® L-carnitine while your insulin level is high, so mealtimes are best (19-20). This applies even more outside of training periods, i.e. in the morning and at lunchtime or on rest days (days on which Carnipure® should still be taken; 21).

During training sessions

A weight training session increases the muscular absorption of carnitine by 40 to 70% compared to usual (18). Muscle contractions facilitate the transportation of carnitine within the cells. As a result, you should take a significant portion of your dose of Carnipure® L-carnitine before, during, and just after your workout.

How do I take Carnipure® L-carnitine?

The problem with carnitine is its assimilation. It only reaches 5-15%, with the rest being eliminated. This makes it difficult to increase carnitine levels in the muscles.
However, there are three solutions that can help you overcome these drawbacks:

  • Carnitine assimilation improves when used in conjunction with carbohydrates. So taking carnitine with a meal facilitates its absorption. 
  • It is also a good idea to spread out your dosage rather than taking it in one go. 
  • The synergy of L-carnitine - Fat Burner - Choline-L-Bitartrate: L-carnitine and Nutrimuscle’s Fat Burner combine perfectly, as choline improves carnitine retention while promoting its cellular integration. A synergy is thus created between these two complementary supplements (23).

Interactions with other Nutrimuscle products

Synergies between supplements

Carnipure® L-carnitine reinforces the effectiveness of pre-training boosters: Natural Bio Booster, Tribulus Terrestris, organic Ceylan green tea, Guayapi organic guarana, and Green Caffeine Bio Booster.

Carnipure® L-carnitine boosts the efficiency of fat burners: Choline L-Bitartrate.

Antagonisms between supplements

To avoid bloating, Carnipure® L-carnitine is not to be taken at the same time as potassium bicarbonate.

Purity of raw materials guaranteed

As with all the products in our range, we make sure to share all the information we have on the origins of our suppliers and the quality of the raw materials used.
We only use the very best ingredients, the quality of which is guaranteed by global leaders: Swiss group Lonza, which is HACCP and ISO9001 certified, produces Nutrimuscle's L-Carnipure® carnitine.
This origin guarantees that L-Carnipure® contains:

  • Zero impurities
  • No traces of D-carnitine (a synthetic form of carnitine not found naturally that inhibits the absorption of L-carnitine)
  • No GMOs
  • No allergenic substances

Each batch of L-Carnipure® is tested to confirm the absence of toxic heavy metals as well as microorganisms, bacteria, microbes, fungi, or mould. These tests are made available to the consumer, which is rarely the case for generic carnitines, of which the source, producer, method of manufacture, purity, date of production, and use-by date is not stated.

Thanks to unique patents, L-Carnipure® is the only carnitine produced via fermentation (as it is naturally). It therefore contains no animal residues, as is often the case with low-cost, low-tech extraction methods. This feature therefore guarantees no transmission of bovine spongiform encephalopathy.

Manufacturing methods and dealers

When we warn against Chinese supplements, it is because they are made with a different lens than the one adopted here by Lonza. The supplements to be wary of are those for which European or American resellers buy at the lowest possible price from local Chinese producers. In this case, the reseller has no control over:

  • The origin of the raw material;
  • The manufacturing process;
  • Quality tests during manufacturing, etc.

The only thing that matters to them is the lowest possible price, so it is normal to find considerable price variations. Lonza's approach is totally different. Lonza is not a reseller; it is a producer. Lonza relocates its factory in order to remain competitive, but without sacrificing the quality of L-Carnipure® which remains a product 100% identical to that initially manufactured in Europe. The only difference concerns only the geographical location of its factory. Otherwise, nothing else changes. It is always Lonza who manufactures in its own factory, with its same patented and unique technology and keeping the same raw materials. The same quality and purity tests are carried out throughout the manufacturing process.

Benefits of L-carnitine Carnipure® in more detail

Essential action on the muscles

Almost all of our carnitine reserves, that is to say from 20 to 25 g, are localized in the muscles. This is where it will have the most effect. In athletes, carnitine:

  • Promotes oxygenation of the muscles thanks to a vasodilator action, which reduces the increase in heart rate and saves oxygen during exercise;
  • Increases the proportion of fats consumed as fuel, which preserves glycogen, thereby repelling fatigue;
  • Accelerates recovery and muscle growth due to its impact on the endocrine system;
  • Raises the density of testosterone receptors on the muscles (therefore the sensitivity of the latter to our testosterone) (1);
  • Promotes the effectiveness of IGF-1;
  • Reduces muscle stiffness by minimizing muscle catabolism (2);
  • Reduces the production of ammonia, a factor of fatigue resulting from the degradation of amino acids (3).

Benefit of L-carnitine against fats
Carnitine plays an essential role in the oxidation of fats. It is this which allows the transport of lipid molecules within the tissues so that they can be burned there. In overweight people who are not on a diet, taking L-carnitine increases the amount of fat used for fuel (4).

Ultimately, this effect results in a melting of fat. Thus, compared to a placebo, in 4 weeks of diet, L-carnitine increases weight loss by 30% (5). In 8 weeks, in high-level athletes, the simple intake of 2 g of L-carnitine, 3 hours before training, lowers the fat percentage by 2.5% (6).

Carnitine works best in the most fat athletes. This fat loss results in an increase in physical performance greater than that noted with placebo (6). In fact, in the absence of a diet, the level of adiposity of athletes on placebo does not vary. A new study (8), very detailed, particularly at the genomic level, reveals the secrets of the effectiveness of carnitine against fat. By regulating the activity of genes that make us burn fat, carnitine provides more energy during exercise, which increases endurance and increases the effectiveness of the diet.

Mitochondria are organelles that convert our fat into energy. However, the mitochondria are completely impermeable to lipids. For the latter to enter the mitochondria, they need a transporter: it is carnitine. Carnitine allows fat molecules to cross the protective membranes of mitochondria. On the contrary, without carnitine, it becomes almost impossible to burn fat: we are constantly tired and we accumulate fat since we are not able to oxidize fat to transform it into energy.

Increased antioxidant defenses of the body
Research shows that taking 2g of L-carnitine for 2 weeks increases the body's antioxidant defenses by 30% (23). Unlike plants, which themselves contain antioxidants, carnitine works indirectly by increasing the capacity of cellular enzymes that make our own antioxidants like superoxide dismutases (SOD) (24).

This is an essential health action, all the more important as we train intensively on a regular basis, because physical efforts tend to "tire" these enzymes which then start to produce less and less. antioxidants, while the body paradoxically needs them even more than usual. It is through this mechanism of action that carnitine accelerates muscle recovery (23).

It is also these stimulating effects on the body's antioxidant defense capacities that may participate in the benefits of carnitine in extending life expectancy (25).
