Carnosine levels drop as you age:

• The natural loss of skeletal muscle due to aging, combined with a lack of beta-alanine intake through food sources, leads to a decline in carnosine levels.

• Supplementation of beta-alanine is both critical and effective in the continued production of healthy levels of carnosine.

• Sustained RX^® uses the patented sustained release beta-alanine, SR CarnoSyn^®, which remains in the body up to twice as long to maximize carnosine production.

• SR CarnoSyn^® is clinically proven to increase carnosine levels.^†

Vegan, vegetarian, or other dietary restrictions:

• The primary way of ingesting natural beta-alanine through diet is by the consumption of animal protein.

• It is critical for those with vegan, vegetarian, or other dietary restrictions to supplement beta-alanine to ensure healthy carnosine levels.

• Sustained RX^®  products are completely Allergen Free, Vegan, Gluten Free, and 100% Non-GMO.

Sensitivities to beta-alanine:

• Some can experience paresthesia when using instant release beta-alanine. Paresthesia is a harmless tingling sensation that is usually felt in the hands, arms, legs, or feet, but can also occur in other parts of the body.

• Because of this, those sensitive to beta-alanine induced paresthesia tend to avoid instant release beta-alanine supplements.

• Sustained RX^® products are powered by SR CarnoSyn^® patented sustained release beta-alanine, which eliminates or minimizes paresthesia.^†
