General information about L-arginine

Along with BCAA and glutamine, L-arginine is one of the best known and most popular amino acid supplements among athletes.

L-arginine belongs to the semi-essential amino acids, i.e. it can be produced by the body itself, but often not in sufficient quantity for regular exercise.

Why is L-arginine so important for our body? Arginine is involved in a large number of processes in the body, including the formation of nitric oxide, one of the smallest messenger substances in the body. Nitrogen is also known to be the main substance responsible for the protection and regulation of blood vessels. Particularly interesting here is the fact that nitric oxide promotes vasodilation and improves nutrient transport to the muscles. 

Arginine therefore helps supply the muscle cells.

Due to the characteristics described above, L-arginine is primarily used before exercise for a positive impact on strength and endurance levels.

Differences in quality arise in the pharmaceutical form of arginine. Inferior arginine HCL (hydrochloride) supplements are often extracted from human hair or duck feathers. By contrast, high-quality L-arginine has a much larger content of real arginine, better bioavailability and is fermented from plant sources like corn or sugar cane molasses.

L-arginine for strength and endurance

L-arginine is primarily used to support training performance in terms of strength and endurance levels. It is also suitable for muscle building as a "booster" for your workout.

An additional intake of L-arginine in conjunction with an exercise regime supports nutrient transport - this results in a better supply to the muscles and increased performance in strength and endurance training.

The effects of L-arginine

In the world of strength and weight training, "pumping" is often mentioned in conjunction with arginine. How does L-arginine force/promote muscle pumping in weight training? A noticeably improved supply of carbohydrates and proteins, along with improved blood circulation, makes you feel like you have more power available to you.

Meaning you can lift heavier weights or complete more reps. This leaves the muscles well supplied with all the nutrients they need and means they can work effectively.

Who should use L-arginine?

Arginine is ideal for weight lifters who want to improve the nutrient supply to the muscles and support exercise performance. This can often lead to you being able to achieve more reps, lift heavier weights and manage with shorter breaks, which makes the workout more successful in terms of a progressive increase in strength.

A study by an English university has shown that with additional arginine, endurance athletes could train for up to 20% longer and overall endurance improved by 1 - 2%. Blood pressure was also improved.

The correct intake of L-arginine

Weight lifters should take L-arginine on an empty stomach about 30-60 minutes before exercising, in order to benefit from the full effect. L-arginine can also be taken on non-training days to support your training performance, although this is not strictly necessary.

Arginine available in powder or capsule form, Both forms are well tolerated by the body and are rapidly absorbed. The biggest difference is in the taste.

L-arginine has a naturally unpleasant taste, but the capsules are tasteless and easier to take in this sense.

Even when combined with juice the powder retains its fishy, salty, bitter taste, making it a lot less popular than capsules. L-arginine capsules have the additional advantage that they are easy to dose and easy to carry.

Possible side effects of L-arginine

Taking more than 15 grams a day may cause temporary digestive problems, stomach  cramps or nausea.

If you follow the recommended dosage you need not worry about side effects.

Buying L-arginine online – what you need to look out for

A large number of online retailers sell L-arginine. However, there are significant differences in quality. Before buying, you should check which nutrients and ingredients are used.

Most arginine products use arginine HCL (hydrochloride) as a pharmaceutical form. The human body does not absorb arginine hydrochloride so well. The raw materials from which inferior hydrochloride is extracted, are often human hair or duck feathers.

The high-quality alternative is called arginine. This has a significantly higher bioavailability in the body. Arginine is produced by fermenting raw materials like whey, corn or sugar cane molasses.

Premium L-arginine by foodspring consists of pure fermented corn. It is also 100% free of artificial flavours and both gluten- and lactose-free. And the capsules are vegan.

Frequently Asked Questions
Is your L'Arginine hydrochloride?

No, it's not hydrochloride. We use pure L'Arginine, which is a free amino acid.

What is the difference between arginine and hydrochloride?

The raw material arginine hydrochloride is often used in low-cost products. The basic ingredient in these products is arginine that has been extracted from human hair or duck feathers. However, the premium raw material arginine is produced from the fermentation of plant materials.

What is the benefit of capsule shells made of cellulose?

By using capsule shells made of plant fibres, we can offer an even greater natural quality for a 100% vegan product.
