Melcalin® Pralginina

Pack: 56 tablets
Net Weight: 56 g


Melcalin Pralginina is an L-Arginine-based food supplement that is useful in case of poor nutritional intake or increased need for this nutrient.


Arginine is a semi-essential amino acid that is vital for the production of nitric oxide1,2.
Many of the activities of L-arginine, including its possible anti-atherogenic action, can be explained by its role as a precursor of nitric oxide (NO), a molecule produced by all of the tissues of the body and able to play very important roles in the cardiovascular system, the immune system and the nervous system5.

Melcalin® Pralginina (negative-PRAL L-arginine) is a food supplement containing buffered L-arginine; its formulation has been designed with the addition of minerals such as potassium and magnesium because the acid-base balance is extremely important for the wellbeing of the entire body. Acidifying load increases correlate to a number of issues such as higher systolic and diastolic pressure, higher total cholesterol, higher LDL, lower mineral content in the bone tissue as well as lean mass loss26,27,28,29,30. Achieving proper body pH is therefore vital for maintaining general health25.
This association combines the multiple properties of L-arginine with the buffering action of the minerals that support its activity.

  • L-Arginine hydrochloride
  • magnesium salts of citric acid
  • potassium citrate
  • bulking agents: microcrystalline cellulose, hydroxypropylmethylcellulose
  • anti-caking agents: polyvinylpyrrolidone, mono and diglycerides of fatty acids, magnesium salts of fatty acids, silicon dioxide

Fields of application:

  • helps improve the endothelial function;
  • helps reduce cardiovascular risk (decreases blood pressure, increases HDL and decreases LDL, cholesterol and triglycerides);
  • supports the immune system;
  • helps enhance physical performance (improves strength and power);
  • helps improve sexual function in men with erectile dysfunction.

Method of administration:

2 tablets daily with a glass of water, starting from the first meal of the day

Storage instructions:

Store cool and dry place, away from heat or direct sunlight. The expiry date indicated refers to the product correctly stored in its undamaged package.
