Lean On, a new supplement brand co-founded by sisters Alesha and Natalie Peluso, is entering the GLP-1 companion nutrition space with two debut SKUs — DeepSculpt and LiquidGold — formulated to address the nutritional deficits that frequently accompany rapid, medication-assisted weight loss.
The launch places Lean On inside one of functional nutrition's most crowded and fast-moving emerging segments. As GLP-1 receptor agonists such as semaglutide and tirzepatide drive significant caloric restriction, clinicians and dietitians have flagged downstream risks including lean-muscle loss, micronutrient insufficiency, and inadequate protein intake — gaps that a targeted finished formulation strategy is well-positioned to fill.
The Products
DeepSculpt appears positioned around muscle preservation, a critical clinical endpoint for GLP-1 users whose rapid weight loss can carry a disproportionate loss of lean body mass alongside fat. LiquidGold's naming convention suggests a bioavailability-optimized, liquid-delivery micronutrient or omega-based formula — a format increasingly favored in GLP-1 companion nutrition because reduced appetite and altered gastric motility can impair absorption of standard tablet or capsule supplements. Neither the specific ingredient deck nor dosage specifications were disclosed in the announcement.
Market Context
The GLP-1 companion supplement category has attracted significant industry attention over the past 18 months, with established ingredient suppliers, contract manufacturers, and emerging indie brands racing to establish structure-function claims around muscle retention, gut comfort, and micronutrient repletion for this patient population. Market analysts tracking the weight-management supplement segment have noted that GLP-1 adjacency is reshaping product development roadmaps across protein powders, electrolytes, and multivitamin formats alike — trends covered in depth in Functional News's weight management and sports nutrition coverage.
For operators and buyers, the category dynamic is compelling but crowded: differentiation increasingly hinges on clinical substantiation, transparent labeling, and delivery formats suited to users with significantly reduced food and pill burden. Brands that can anchor structure-function claims to peer-reviewed evidence or at minimum to well-characterized ingredient science will hold an advantage over those relying solely on GLP-1 trend positioning.
Lean On's founder-led, women-focused positioning may also resonate with the demographic skew of GLP-1 adoption, which, per prescribing data, trends female. Whether the brand pursues direct-to-consumer, specialty retail, or clinical/telehealth channel distribution has not yet been disclosed.

Frequently Asked Questions
What specific nutritional gaps are Lean On's formulas targeting in GLP-1 users?
DeepSculpt addresses lean-muscle loss, which clinicians flagged as a major risk when semaglutide and tirzepatide drive rapid caloric restriction. LiquidGold tackles micronutrient insufficiency and bioavailability challenges created by reduced appetite and altered gastric motility in GLP-1 patients.
Why is Lean On using liquid delivery for LiquidGold instead of tablets or capsules?
GLP-1 users experience suppressed appetite and compromised gastric motility, which impairs absorption of standard tablet and capsule formats. Liquid delivery systems optimize bioavailability in this population, making them the preferred delivery mechanism emerging across the entire GLP-1 companion nutrition category.
Who are Alesha and Natalie Peluso, and what's their background in functional nutrition?
The article doesn't disclose their backgrounds, only that they co-founded Lean On together. You'll need to request their founder bios directly from the company for investor or partnership discussions.
How crowded is the GLP-1 companion supplement market right now?
Ingredient suppliers, contract manufacturers, and indie brands have all entered the space over the past 18 months, racing to claim structure-function territory around muscle retention, gut comfort, and micronutrient repletion. It's one of functional nutrition's fastest-moving emerging segments, making early differentiation critical.
When will Lean On disclose the specific ingredient decks and dosage specs for DeepSculpt and LiquidGold?
Those details weren't included in the launch announcement. Contact Lean On directly for full ingredient transparency, COA data, and clinical substantiation before committing to shelf space or formulation partnerships.
