iHerb launches new GLP-1 support products designed to combat common side effects from rapid weight loss

iHerb has launched three new supplements specifically designed to support individuals using semaglutide (GLP-1 agonists) by addressing common side effects such as digestive issues including nausea and pain, loss of muscle mass and skin elasticity, and changing blood sugar levels.

The new GLP-1 support product line, CollagenUP Plus, Berberine Advanced and Digestion Pro, are the latest innovations under California Gold Nutrition, iHerb's house brand of vitamins, minerals and supplements. These dietary supplements were conceived and developed to address key nutrient deficiencies that may occur when a person's appetite is significantly reduced.

Recent research on weight management drugs projects that 93 million adults in the US who are overweight and obese may benefit from a GLP-1 agonist medication. In spite of the rising adoption, a recent report revealed 60 percent stopped using their GLP-1 medication before reaching their targeted duration, with many citing negative side effects as a factor for quitting the medication.

In response to these challenges, iHerb's new dietary supplements are specifically designed to address common side effects from GLP-1 medications and help increase the likelihood of individuals to maintain their weight loss programme.

"Our goal was to create products that addressed the side effects of GLP-1 head on, from improved digestive function, to enhanced metabolism and blood sugar support, and better-retained muscle mass," commented iHerb Chief Scientific Advisor, Dr Michael Murray. "Each of these products was carefully designed using the highest-quality natural ingredients to ensure optimal effectiveness."

Supplements Overview

The launch of California Gold Nutrition's CollagenUP Plus, Berberine Advanced and Digestion Pro are meticulously formulated using premium ingredients to ensure product potency and efficacy. These supplements are only available at iHerb, do not require a prescription and are safe to use by individuals who are not planning to pursue GLP-1 therapy.

  • CollagenUP Plus is designed to prevent muscle loss as well as regulate blood sugar levels and minimize nausea and bloating. When mixed with water, it meets the criteria of a small particle-size meal that supports proper gut function in users of GLP-1 agonists. CollagenUP Plus contains hydrolyzed marine collagen to help keep skin firm, prebiotic fibre blend to further promote digestive health, and essential amino acids to support muscle health.

  • Berberine Advanced features Berbevis, a phytosome formulation that has been proven to effectively support healthy body composition and blood sugar levels, and has a positive effect on body composition. Beyond metabolic support, Berberine Advanced can also support heart health, aid in weight management, and contribute to overall gut health.

  • Digestion Pro features Prodigest, a patented plant-based blend designed to optimize digestive function. Supplementing GLP-1 treatment with Digestion Pro can help safeguard against potential side effects such as bloating, nausea and stomach pain.

GLP-1 patients will also find a curated assortment of beneficial vitamins and minerals such as vitamin B6, iron, vitamin D3+K2, magnesium and folate to help replenish any nutrient deficiencies caused by a reduced intake of fortified and animal source foods.

"After months of preparation, we are proud to introduce our new California Gold Nutrition supplements specifically formulated to mitigate the adverse effects of GLP-1 therapy," said Emun Zabihi, CEO of iHerb. "We have developed products that enhance overall well-being and demonstrate our dedication to addressing our customers' needs.
