Berberine 5x

Description

LifeSpa’s Berberine 5x features dihydroberberine (DHB), a highly bioavailable metabolite of berberine with demonstrated benefits for blood glucose metabolism. Berberine naturally occurs in several plant species used extensively in traditional Ayurvedic and Chinese herbal practices; DHB is the natural bioactive form of berberine

LifeSpa’s® Berberine 5x contains DHB originating from berberine sourced from Berberis aristata and naturally extracted through an enzymatic process similar to that which occurs in the human gut. With a 5-fold relative increase in absorption rate, supplemental DHB at much lower doses than berberine has comparable beneficial metabolic effects.*

LifeSpa’s medical-grade supplements are designed to support specific bodily functions. Each LifeSpa formula has been carefully researched, developed and clinically tested, using a combination of science and innovation to create a thoroughly effective product.

Discussion: Berberine is a plant alkaloid derived from several different plant species customarily used in Ayurveda and traditional Chinese medicine for various therapeutic applications. Modern clinical use and published in vivo, in vitro, and animal research studies
demonstrate that the berberine metabolite dihydroberberine (DHB) is more bioavailable than berberine and offers enhanced support
for healthy blood glucose metabolism.*1-5

Although the mechanisms underlying the beneficial effects of berberine are not entirely clear, it is hypothesized that the modulation
of gut microbes may be one mechanism by which berberine affects blood glucose metabolism.6 Results from animal and in vitro studies suggest that berberine moderates glucose and lipid metabolism through a multi-pathway mechanism, including the adenosine monophosphate–activated protein kinase (AMPK), c-Jun N-terminal kinase (JNK), and peroxisome proliferator-activated
receptor (PPAR)-alpha pathways.2,7 Separate research on AMPK reports activating the AMPK pathway stimulates glucose uptake
and fat oxidation while suppressing lipogenesis and gluconeogenesis.8 Berberine is also believed to be involved in the regulation of
pancreatic beta cell function, and it has been observed to inhibit the expression of disaccharidases in the duodenum, resulting in less
glucose formation from carbohydrate digestion.*9

Increasing evidence indicates that gut microbiota are also crucial mediators that regulate berberine’s pharmacokinetic and biological
effects. Berberine induces compositional alterations in gut microbiota and regulates gut microbe–dependent metabolites, factors that contribute to its biological effects on lipid and glucose metabolism.10,11 Additionally, gut microbiota reduce berberine to DHB, its
intestine-absorbable form, which then oxidizes back to berberine after it has been absorbed into intestinal tissues and entered the
blood.*4

Berberine absorption across the intestinal epithelia is suggested to be compromised because of its “flat” chemical configuration. Berberine displays poor bioavailability and increased potential for GI distress at the oral doses required to improve biomarkers associated with glucose homeostasis.3 The structure of the DHB derivative of berberine is comparably open, making it more amenable to uptake. To further explore the absorbability of berberine and DHB, researchers investigated the mechanism of action by which AMPK is activated and if using DHB at lower doses than berberine could potentially improve the effect on adiposity and glucose metabolism in rodents fed a high-fat diet.

Berberine had to be administered at a nearly 5-fold increased dose of 560 mg/kg/d to establish the same effects demonstrated by DHB at
100 mg/kg/d. The rodents treated with the substantially lower dose of DHB showed markedly reduced adiposity and improved glucose
tolerance. Additionally, insulin sensitivity was increased in the DHB-treated animals. These results led researchers to suggest that
the difference in effects between berberine and DHB is due to the enhanced bioavailability of DHB. The findings of this study indicate
that DHB delivers the beneficial metabolic effects of berberine in a more absorbable form and at a lower dose.*5

A small, randomized, double-blind, crossover pilot study (N = 5) investigated the absorption kinetics and compared the dosing of
berberine and DHB required to achieve peak plasma concentrations. Subjects completed a 4-dose protocol of placebo, 500 mg of
berberine, 200 mg of DHB, and 100 mg of DHB. Participants ingested the first 3 doses with breakfast, lunch, and dinner, followed
by an overnight fast, then a standardized test meal accompanied by dose 4. Blood samples were collected at regular intervals
after ingestion and analyzed for berberine, glucose, and insulin. Four doses of 100 mg and 200 mg of DHB produced significantly
greater concentrations of plasma berberine across the 2-hour measurement window than a 500-mg dose of berberine or placebo.
Results suggest that irrespective of dose, DHB achieves a greater area under the curve and peak berberine concentrations when
compared with oral ingestion of berberine.*12
