Creatine is one of the most widespread and popular dietary supplements, since it is associated with strength, muscle volume and endurance. In recent years, a real revolution has begun in the field of creatine, with new types of creatine and amazing combinations. An important step was the appearance of KRE-ALKALYN. Alkaline creatine overturned the data on the content and use of creatine by athletes. KRE-ALKALYN contains pure, 100% KreAlkalyn, concentrating all the beneficial effects of creatine without the disadvantages of monohydrate.
The main difference of KRE-ALKALYN is the change in its pH. When a supplement is taken orally, it has a specific pH, which changes when mixed with liquids and when it comes into contact with the gastric juices of the stomach. This results in its absorption being difficult. In the case of simple creatine, this alteration converts creatine into creatinine, a useless substance. Only a part of the creatine taken is absorbed by the muscles due to the alteration in pH.
KRE-ALKALYN alters the initial pH of the product and ensures that the amount taken orally is fully absorbed by the muscles, increasing the beneficial effects. This eliminates the possibility of it being converted to creatinine and causing the negative effects of simple creatine. For this reason, a very small dose of KRE-ALKALYN is needed for maximum results.
It is noteworthy that no overload period or interruption is required after 1 month of use, you can use it for a long time without any problem. Another advantage is that it does not cause water retention or bloating in the stomach, with the muscle mass you gain being clean, without water.
Users who have purchased it stand out mainly because it does what it promises and dissolves easily.
