Before you go running to buy the anti-aging supplement L-carnosine, there may be a less expensive way to boast your blood levels of carnosine than by using a carnosine supplement.
The Dr. Oz Show has tauted L-carnosine as a miracle pill to stop aging. It is found in skeletal muscle, heart muscle, skin and in your brain. Even though scientist do not know exactly what carnosine does, it does appear to slow down cellular deterioration and promote cellular rejuvenation.
Our bodies can produce this miracle molecule by combining the two amino acids beta-alanine and histidine. However, as we age, carnosine levels tend to fall. The lower levels of carnosine as we age may be partly responsible for increased cellular deterioration and reduced physical activity of the elderly.
Research at the University of Oklahoma and Ghent University show that beta-alanine supplements can increase carnosine levels in skeletal muscle, and increase the physical working ability of the elderly. So, the most cost effective way to increase the carnosine levels in our bodies may be to take beta-alanine supplements rather than L-carnosine supplements.
The study at the University of Oklahoma uses a dosage of 2.4 grams of beta-alanine per day. Dr. Oz recommends 1000 mg of L-carnosine per day to slow the aging process. Using these two dosages, it cost 11 cents per day for the beta-alanine supplement, and 55 cents per day for the L-carnosine supplement. As you can see, there is a huge cost advantage in using beta-alanine rather than L-carnosine.
Since beta-alanine is effective in increasing carnosine levels in skeletal muscle and is quite a bit less expensive, I would consider beta-alanine as the better alternative in helping us find the fountain of youth.
