Casein has been known for a long time that it prevents muscle destruction, the so-called catabolism, that it strengthens the defenses and that it has a high biological value, which is why it is used in most supplements that seek to gain muscle mass and improve strength in athletes of practically all disciplines.Due to its anti-catabolic properties, it is recommended to take it before a long period of fasting, such as before going to sleep.It is also a slow-acting protein, which is absorbed at a slower rate than whey or whey protein, so it supplies a gradual and constant flow of amino acids to the blood, over several hours, and that favors recovery.On the other hand, in the world of supplementation there is also a lot of talk about nitric oxide since this substance increases performance, improves recovery and delays fatigue by allowing the supply of oxygen and nutrients to the muscles to increase.There are supplements that are based on the ingestion of Arginine, the precursor amino acid of the reaction that produces Nitric Oxide, which seek to increase its concentration to achieve the mentioned beneficial effect, but there is no scientific literature that supports these arginine supplements, [4 ], which could only be useful in some special case.In addition, the ingestion of arginine could become dangerous in case of overdose [5].What we have told you before is information that has been with us for a long time, however it is totally new that casein, the milk protein not included in whey, when ingested with a certain degree of hydrolysis, contains bioactive peptides that release the Nitric oxide.See: https://proenos.com/fundamento-cientifico/ [doc B]Casein releases nitric oxide, thereby achieving greater performance in sports.The above statement is the result of an investigation carried out in the last 12 years in Spain [doc A,B,C,D,E] .Casein achieves this effect through the activation of the Endothelial Nitric Oxide Synthase enzyme, eNOS [doc B], without which the reaction to generate Nitric Oxide does not occur, as illustrated in the following video.It should be noted that to achieve this effect, it is not necessary to ingest arginine separately, as others postulate, since the bioavailable amount of arginine contained in hydrolyzed casein is already sufficient [doc D].One of the best ways to take casein to achieve this effect is with supplements such as Proenos Sport, which contains hydrolyzed casein, an extract from two plants that have synergistic effects with bioactive peptides on blood circulation, Ginkgo Biloba [doc C, 6 ,7,10] and Rhodiola Rosea [8,9,10], and minerals such as Zinc, Selenium and Magnesium.It's a side effect-free supplement using natural ingredients that popular runners, cyclists, and gym goers alike will benefit from as an all-natural boost that improves endurance and shortens recoveries between workouts.It has three mechanisms of action, resulting in increased endurance and reduced fatigue for faster recovery:1. Induces the generation of Nitric Oxide that makes the arteries more flexible, allowing greater bioavailability of active ingredients and supply of Oxygen and nutrients to the muscle [1,2,3].2. Transports minerals to the intestine [doc E, 11] making them more bioavailable, to take advantage of the powerful antioxidant action of Zinc and Selenium and the regenerating action of Magnesium.3. It decreases the levels of cortisol (stress hormone) that is generated during long training sessions [10].More information: https://proenos.com/Bibliography:CONSENT FOR THE PROCESSING OF PERSONAL DATA: If you check the boxes that appear at the end of this text, you will be declaring: (i) that you are over 16 years of age; (ii) that the information you have provided us during the process of registration is true; (iii) that you unconditionally accept the terms and conditions that appear in the Legal Notice, the Privacy Policy and the Cookies Policy whose links appear, in addition to here, at the end of this web page;and (iv) that you give us your express consent so that your personal data (name, surname, username, password, email, postal address, telephone number, gender and date of birth) are processed by MOTORPRESS IBÉRICA SAU (CIF A - 82090952, registered office at Calle Nestares 20, 28045 Madrid, Spain, telephone 913470100 and emailmotorpress-iberica@mpib.es) for the following purposes:Consent to the processing of your personal data for the purpose set forth in section “a.”above (registering you as a user of this website) is different and independent of the treatment of the same for the purposes set forth in section "b."(analyze your data for market research and electronic marketing purposes, to send you advertising information).Revocation of consent.-We will treat your data as long as you do not withdraw the consent that you now grant us, withdrawal that you can make at any time, with instant effect, by sending by postal mail to the registered office of MOTORPRESS IBÉRICA SAU, Calle Nestares 20, 28045 Madrid, Spain, to through the web form available here, or through the email address protecciondatos@mpib.es.Likewise, and with respect to the instant messaging channel only, you can unsubscribe from it by responding with the word "unsubscribe" to any of those you receive.Exercise of rights.-For the exercise of the rights that assist you, of access to your data, rectification, deletion or limitation of the treatment of the same, obtain a copy of the data or make effective the right to the portability of these, you must contact by post to the registered office of MOTORPRESS IBÉRICA SAU, calle Nestares 20, 28045 Madrid, Spain, or through the web form available here or through the email address protecciondatos@mpib.es.Conservation of your personal data.-MOTORPRESS IBERICA SAU has adopted the corresponding security measures for the conservation and custody of your personal data, and has appointed a Data Protection Delegate, despite not currently being obliged to do so, to which can be contacted at the registered office of MOTORPRESS IBÉRICA SAU, calle Nestares 20, 28045 Madrid, Spain or through the email address dpo@mpib.es.Whatever the reason for the processing of your personal data, we will keep your data duly blocked and archived to deal with any legal responsibilities, for a maximum period of five years.Possibility of making claims before the AEPD.- In any case, we expressly remind you that you have the right to make the claims you deem appropriate before the Spanish Agency for Data Protection (www.agpd.es), based in Madrid, calle de Jorge Juan 6 (CP 28001), or before the equivalent bodies of the Autonomous Communities© 2020 Motorpress Iberian.All rights reserved.
