About the Product
Marvelous Nutrition's Recharge is a Glucose Disposal Agent (GDA) in HPMC vegetable capsules, formulated with 7 bioactive ingredients that work synergistically to mimic and enhance insulin action, redirecting ingested carbohydrates to skeletal muscle (instead of being stored as fat). Insulin is the most potent anabolic hormone in the human body – it promotes glycogen and muscle protein synthesis and inhibits lipolysis – and Recharge is designed to maximize insulin sensitivity and nutrient uptake by muscle in the context of high-carbohydrate meals. Key ingredients include: Berberine HCl 97% (the most potent natural insulin sensitizer, comparable in efficacy to antidiabetic drugs), Gymnema sylvestre 75% gymnemic acid (reduces sugar absorption and stimulates insulin secretion), Momordica charantia 10% charantin (the "bitter melon" with documented hypoglycemic effects), Cinnamon (Cinnamomum cassia + verum, two types of cinnamon with distinct insulin-mimetic properties), R-ALA (R-alpha-lipoic acid, the natural bioactive form of ALA with effects on glucose transport and vasodilation), and Chromium picolinate (a mineral cofactor for insulin signaling). Vegan.
Benefits
The GDA concept: what is a glucose disposal agent and what is it for:
A GDA (Glucose Disposal Agent) is a supplement that improves the efficiency with which the body processes and utilizes ingested carbohydrates, particularly in the post-meal context. The central mechanism is the improvement of insulin sensitivity in target tissues (primarily skeletal muscle and liver), i.e., the ability of muscle cells to respond to the insulin signal and take up glucose from the bloodstream more efficiently. In athletes and bodybuilders who consume large amounts of carbohydrates (especially during bulking phases), an effective GDA serves two purposes: during the bulking phase, it maximizes muscle glycogen synthesis and the post-workout anabolic insulin response while minimizing fat deposition from excess carbohydrates; during the cutting phase with a low-carb diet, it keeps muscle cells "full" (with glycogen) even with lower carbohydrate intake, by maximizing the efficiency of muscle uptake of available carbohydrates.
Berberine HCl 97% (Berberis aristata): the most potent insulin sensitizer in the plant kingdom:
Berberine has already been described in detail in the Life Pro Berberine 500 mg section. In the context of Recharge, its role as a GDA is central: berberine activates AMPK (AMP-activated protein kinase) in muscle and liver cells – the same metabolic sensor activated by metformin (the first-line drug for type 2 diabetes and the most prescribed worldwide) – which stimulates GLUT4 translocation to the plasma membrane of myocytes independently of insulin, increasing glucose uptake by muscle. Berberine also inhibits hepatic gluconeogenesis (reducing endogenous glucose production by the liver) and improves the sensitivity of insulin receptors. Multiple meta-analyses have documented that berberine (at doses of 1 to 1.5 g/day) reduces fasting glycemia, HbA1c, and triglycerides comparably to metformin in people with type 2 diabetes or pre-diabetes. The extract of Berberis aristata standardized to 97% Berberine HCl is one of the most concentrated and pure forms available on the market, guaranteeing the active dose per capsule.
Gymnema sylvestre 75% gymnemic acid: the Ayurvedic "sugar destroyer":
Gymnema sylvestre (Gudmar, "sugar destroyer" in Sanskrit) is a climbing plant from Ayurvedic medicine used for centuries in the Indian subcontinent for the treatment of diabetes. The gymnemic acids (the group of triterpene saponins standardized in the 15:1 extract to 75%) have two distinct mechanisms of action on glucose metabolism. The first is the reduction of intestinal glucose and sucrose absorption: gymnemic acids have a molecular structure similar to sugars and compete for glucose transporters SGLT1 and GLUT5 in the intestinal mucosa, reducing glucose and fructose absorption. The second is the stimulation of pancreatic beta cells: Gymnema sylvestre stimulates the regeneration and proliferation of beta cells in the islets of Langerhans and increases insulin secretion in response to glucose, which in combination with berberine (which increases peripheral insulin sensitivity) creates a synergistic effect of complete improvement of the insulin axis.
Momordica charantia 10% charantin (bitter melon): the herbal hypoglycemic agent with the most clinical trials in diabetes:
Momordica charantia (karela, bitter melon) is a tropical cucurbit with the most extensive ethnobotanical and clinical studies on natural hypoglycemia. Charantin (standardized to 10% in the fruit extract) is a mixture of two glycosidic steroids with insulin-like activity: it increases glucose uptake by peripheral tissues (muscle and adipose tissue), stimulates glycogen synthase (muscle glycogen synthesis), and inhibits glucose-6-phosphatase and fructose-1,6-bisphosphatase (enzymes of hepatic gluconeogenesis). In addition to charantin, Momordica fruit contains polypeptide-P (an insulin-mimetic peptide that directly activates insulin receptors) and vicine (another compound with hypoglycemic activity). The review by Joseph & Jini (2013) compiled data from 15 clinical and preclinical studies on Momordica charantia and glucose, documenting consistent reduction in fasting and postprandial glycemia.
Cinnamon (Cinnamomum cassia + Cinnamomum verum): insulin-mimetic and GLUT4 activator:
The formula uses a combination of Cinnamomum cassia (Chinese cinnamon, the most common cinnamon in supplements) and Cinnamomum verum (Ceylon cinnamon, "true cinnamon," with lower coumarin content and higher concentration of cinnamaldehyde and procyanidins). Cinnamaldehyde (the main aromatic component of cinnamon) and type-A procyanidin polymers from cinnamon bark have an insulin-mimetic effect via activation of the insulin receptor by phosphorylation, stimulation of GLUT4 translocation to the myocyte membrane, and inhibition of protein tyrosine phosphatase 1B (PTP1B, the enzyme that dephosphorylates the insulin receptor and terminates the insulin signal). The meta-analysis by Allen et al. (2013), published in the Annals of Family Medicine with data from 10 randomized clinical trials, documented that cinnamon supplementation reduced fasting glycemia, LDL-cholesterol, and triglycerides compared to placebo.
R-ALA (R-alpha-lipoic acid): vasodilation, glucose absorption, and mitochondrial antioxidant:
R-ALA (the natural R form of alpha-lipoic acid, as opposed to the synthetic R,S-ALA racemate) is a cofactor of the mitochondrial respiratory chain with multiple functions in glucose metabolism. The R form is the only biologically active one: it is synthesized endogenously in the mitochondria and is a cofactor for pyruvate and alpha-ketoglutarate dehydrogenases (central enzymes of the Krebs cycle and the glycolysis/Krebs cycle link). In addition to its mitochondrial function, R-ALA increases glucose absorption by muscles by stimulating GLUT4 translocation to the plasma membrane of myocytes (via activation of PI3-kinase and AMPK), a synergistic effect with berberine and cinnamon. R-ALA is also a potent broad-spectrum antioxidant (water-soluble and fat-soluble) that regenerates oxidized vitamin C, vitamin E, and glutathione, reducing oxidative stress associated with postprandial glucose spikes. The study by Jacob et al. (1999) documented that 600 mg of ALA intravenously increased glucose uptake by muscle by 50% in patients with type 2 diabetes.
Chromium picolinate: the mineral cofactor of insulin sensitivity:
Trivalent chromium (Cr³⁺) is an essential trace element that enhances insulin action at the level of its membrane receptor, probably via chromodulin (or LMWCr, low molecular weight chromium-binding substance), an oligopeptide that is activated by chromium and stimulates the kinase activity of the insulin receptor. Chromium deficiency is associated with reduced glucose tolerance and subclinical hyperglycemia. Chromium picolinate is the form of chromium with the highest oral bioavailability (picolinate forms a chelate with Cr³⁺ that facilitates intestinal absorption and reduces urinary excretion). EFSA has approved the health claim that chromium contributes to the maintenance of normal blood glucose concentrations.
Uses
Recommended dose: Take with high-carbohydrate meals (before or during the meal that includes the largest volume of carbohydrates of the day — typically breakfast or post-workout meal). For use as a post-workout GDA, take immediately before or during the post-workout recovery meal (which usually includes high-GI carbohydrates + protein). Berberine has a short half-life (~3 hours) and its effects are more pronounced when taken before high-carbohydrate meals.
