Unlock your potential for a lean, muscular body with Swanson L-Carnitine! A favorite among dieters and bodybuilders, this amazing amino acid helps the body metabolize fat to energize muscles for effective, productive workouts.

L-carnitine is a cofactor—a type of molecule or compound needed by the body to complete enzymatic reactions—in the energy production process. It also helps to transport waste out of your cells, another factor in post-exercise muscle recovery.

Emerging research also suggests that L-carnitine may offer unique benefits for mature adults, easing fatigue and supporting cognitive function.¹

Swanson L-Carnitine delivers 500 mg per serving to promote energy, a healthy body composition and more.

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle that functions alongside the other amino acids to rid the body of ammonia, a byproduct of protein metabolism. Citrulline also plays an important role in the healing process and in the maintenance of a healthy immune system.

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism. Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, which in turn, can be used for the production of Nitric Oxide (NO). NO plays a fundamental role in vascular function and blood flow. Citrulline therefore, not only supports detoxification pathways, but also supports NO production and a healthy cardiovascular system. Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.

Support muscle growth and recovery with Swanson L-Glutamine. Glutamine is the most abundant free amino acid found in the muscles of the body. It may also minimize muscle breakdown and improve protein metabolism. Supporting muscle health and strength promotes joint comfort which is key to mobility and healthy aging.

A versatile amino acid, glutamine may also benefit cognitive function and brain health. It is able to cross the blood-brain barrier and acts as a precursor to important neurotransmitters such as glutamate, aspartate and GABA.

Glutamine also provides fuel for immune cells through its activity in the gut where it may help maintain intestinal barrier function to promote GI tract integrity. Since a solid 70% of your immune system stems from your gut, keeping your digestive system happy is a win for your immune function as well.

Glutamine aids in the production of glutathione, often called the “master antioxidant.” Antioxidants help the body combat oxidative stress caused by free radicals which can in turn support the health of cells and bodily systems as we age.

Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and also aids rapidly growing cells (immune system lymphocytes and intestinal cell enterocytes). Glutamine has recently been the focus of much scientific interest. A growing body of evidence suggests that during certain stressful times, the body may require more glutamine than it can produce. Under these circumstances, glutamine may be considered a "conditionally essential" amino acid. In addition, glutamine is a regulator of acid-base balance and a nitrogen transporter.

Maximum Strength 3-in-1 Carb Blocker from Irwin Naturals features a triple-approach formula with white kidney bean extract, lipase, protease, and chromium picolinate to support healthy metabolism levels already within the normal range. 3-in-1 Carb Blocker delivers a targeted approach for healthy weight management when combined with a healthy diet and exercise plan.

Irwin Natural Maximum Strength 3-in-1 Carb Blocker works to neutralize carbs, enhance digestion and support metabolism. It is specially designed for those who eat pasta, bread and other carbohydrate-rich foods. Unlike most other carb-blocking products that must be taken 20-30 minutes before meals, Maximum Strength 3-in-1 Carb Blocker uses fast-release liquid softgels that can be taken with meals. It is formulated with white kidney bean, an all-natural, non-stimulant ingredient that neutralizes the effect of carbohydrates by inhibiting some of the amylase, the enzyme responsible for digesting starch. Lipase and Protease help break down fats and proteins and optimize the digestion of foods. When combined with a healthy, reduced calorie diet and exercise plan, Maximum Strength 3-in-1 Carb Blocker is a targeted approach to help you achieve your weight loss goals.

NOW Vitamin B-12 is a water soluble vitamin necessary for the maintenance of a healthy nervous system and for the metabolic utilization of fats and proteins. Vitamin B-12 is also essential for the synthesis of DNA during cell division and therefore is especially important for rapidly multiplying cells such as blood cells. In addition, adequate intake of Vitamin B-12, along with Folic Acid and Vitamin B-6, encourages healthy serum homocysteine levels, thereby supporting cardiovascular health. Because Vitamin B-12 is found predominantly in animal products, strict vegetarians are at risk of developing Vitamin B-12 deficiency and may benefit from supplementation.

Methyl B-12 from Now Foods delivers a potent 5,000 mcg per serving. Vitamin B-12 is necessary for the production of energy from fats and proteins and is well known for its critical role in DNA synthesis, as well as in homocysteine metabolism. Methylcobalamin is the co-enzyme form of vitamin B-12 that has been found to be especially critical in the maintenance of a healthy nervous system. Dietary sources are almost exclusively of animal origin (meat and dairy) and supplementation with B-12 may be especially important for strict vegetarians.
