The Promise

What this formula provides — focused carnitine + fumarate blend

A concentrated l‑carnitine fumarate supplement in vegetarian capsules with added fat‑soluble vitamin C.

Active ingredient and form

Contains l‑carnitine in the free‑form as l‑carnitine fumarate, a combined salt of carnitine and fumaric acid.

Per‑capsule amounts

Each vegetable capsule supplies 586 mg l‑carnitine fumarate, standardized to 340 mg free‑form l‑carnitine plus 30 mg ascorbyl palmitate.

Delivery and excipients

Delivered in hypo‑allergenic plant‑fiber vegetable capsules; ascorbyl palmitate provides a fat‑soluble form of vitamin C.

Source and manufacturing notes

l‑Carnitine fumarate is synthetically produced and supplied as a patented composition (58.5% l‑carnitine, 41.5% fumaric acid).

Why It Works

Why this combination matters — complementary components and targeted roles

The ingredients are paired to support energy processes in heart and skeletal muscle and to supply a lipid‑soluble antioxidant form of vitamin C.*

01

Carnitine's biochemical role

l‑Carnitine functions as a carrier of fatty acids into mitochondria to support fat utilization and mitochondrial energy conversion.*

02

Fumarate's energetic contribution

Fumaric acid is a Krebs‑cycle component that contributes to cellular energy generation when combined with carnitine.

03

Synergistic pairing

Carnitine and fumarate are provided together as a single salt to offer dual support for heart and skeletal muscle energy processes.*

04

Fat‑soluble vitamin C included

Ascorbyl palmitate supplies vitamin C in a fat‑soluble form, incorporated at 30 mg per capsule.

l-Carnitine fumarate – Pure Encapsulations L-Carnitine fumerate is generally used for cardiac and athletic support. This amino acid combined with fumeric acid (fumerate), actively supports endurance for athletes, and heart muscles and is known as a cardiovascular nutrient. The l-form of this amino acid can be used safely and effectively with many positive benefits.

What Is It?

l-Carnitine is an amino acid found abundantly in skeletal and heart muscle. It functions primarily to support fat utilization by acting as a carrier of fatty acids into the mitochondria, where they are oxidized and converted to energy. l-Carnitine also facilitates the removal of short and medium chain fatty acids from the mitochondria that accumulate during normal metabolic processes. In studies, l-carnitine has demonstrated the ability to promote oxygenation of heart muscle and maintain healthy enzyme activity, support cardiovascular energy, enhance exercise recovery, and maintain healthy lipid metabolism. Fumarate, or fumaric acid, is an important compound, which is also naturally present in the body. As a component of the Krebs cycle (Citric Acid Cycle), fumaric acid plays a key role in generating energy. Combined, l-carnitine and fumarate provide dual support for energizing the heart and skeletal muscles.*

Uses For l-Carnitine Fumarate Cardiovascular Support: A randomized double-blind placebo-controlled trial involving 101 volunteers indicated that l-carnitine maintained healthy lipid peroxide and lactate dehydrogenase cardiac enzyme activity. l-Carnitine may also support ventricular function and superoxide dismutase enzyme activity. Long-term l-carnitine supplementation has demonstrated positive support for cardiovascular health after a 3-year follow-up in adult subjects. In a recent six-month, randomized, double-blind placebo-co trolled trial, l-carnitine supplementation supported healthy lipid metabolism in volunteers. In a metabolic analysis performed at George Washington University Medical Center, carnitine and fumarate provided synergistic cardioprotective support.*

Support For Exercise Recovery: In a prospective doubleblind placebo-controlled trial, carnitine supplementation supported training for elite athletes. Additional studies suggest that l-carnitine promotes exercise recovery by moderating tissue damage, decreasing production of free radicals and reducing muscle soreness following exercise.*

What Is The Source?

l-Carnitine fumarate is synthetically produced. It is patented worldwide by BIOSINT SpA (58.5% l-carnitine, 41.5% fumaric acid, US patent number 4,602,039). Vitamin C (ascorbyl palmitate) is derived from corn dextrose fermentation and palm oil. Hypo-allergenic plant fiber is derived from pine cellulose.
