Creatine is a compound based on amino-acid. It is naturally produced in the human body. Our body produces half of the required endogenously from internal amino acids and the other half is produced from the food we eat. A lot of Creatine is found in fish and red meat. However, the very best source of creatine by far is creatine monohydrate because it contains more creatine per weight of material than any other source. Creatine is produced by the liver, pancreas and kidneys and is sent to the muscle through the blood. It is then converted into phosphocreatine molecules that store energy in muscular tissues.
Creatine is now sold in different forms. There are many different opinions concerning the pros and cons of using powder, pills or serum Creatine.
Powder can be absorbed by blood more efficiently than a pill, which has a coating that must be first dissolved. Powder is also much more efficient in dosing.
Some specialist claim that liquid Creatin absorbs much quicker and thus is more effective than a powder.
Any way you should trust any claims of instant absorption of Creatine – that’s just not possible. Both creatine serum and powder take time to absorb. Also there are many claims that the Creatine serum is completely stable - you should know that creatine in its liquid form is unstable, and can degrade to another substance called creatinine, which is useless for the muscles.
In short, ignore any claims that says creatine serum possess extra capabilities than creatine powder - they’re both creatine, and they both do the same stuff.
