Capabilities

Built for multiple form factors.

From formulation through fulfillment — our 75,000 sq ft facility handles the full production cycle with the speed, precision, and quality your brand demands. Every format. Every scale.

Powder Manufacturing

Bulk and sachet powders for protein, greens, pre-workouts, and supplement stacks. Precision blending, custom flavoring, and fill-to-finish packaging under one roof.

Capsules

Hard gelatin and vegetarian capsules across a range of fill weights and formulations. Consistent weight tolerances and clean encapsulation across every batch.

Tablets

Film-coated, chewable, and extended-release tablet formats. High-speed compression with strict weight and hardness tolerances maintained batch after batch.

Stick Packs

Single-serve stick packs for on-the-go convenience — electrolytes, collagen, and functional blends. Precision filling with print-ready packaging.

Bottling

High-speed bottle filling for capsules, tablets, and powders. Automated counting, cotton insertion, induction sealing, and labeling — retail-ready.

Packaging & Fulfillment

End-to-end packaging design, secondary packaging, kitting, and direct fulfillment. Your product, shelf-ready — shipped to your warehouse or direct to customers.

Custom Formulation

In-house R&D team develops proprietary blends and optimizes existing formulas for manufacturability, regulatory compliance, and efficacy.

Quality Testing

Comprehensive in-house and third-party testing for potency, identity, microbial limits, and heavy metals. Every batch released against a strict COA.

How It Works

From concept to shelf
in four clear steps.

Concept & Brief

Tell us your product vision — format, target dose, market, and timeline. We review your brief and respond within 48 hours with a clear path forward. No jargon, no runaround.

Formulation

Our R&D team develops or refines your formula to exact specification — optimized for manufacturability, regulatory compliance, and the efficacy claims your brand needs to stand behind.

Manufacturing

Full-scale production in our cGMP-certified, FDA-registered facility. Batch records, in-process quality checks, and COA-backed release — every time, without exception.

Delivery

Finished product to your warehouse, retail partner, or fulfillment center. We handle secondary packaging, labeling, and compliance documentation end to end.

Why Kelker

The direct-from-manufacturer advantage.

Most brands work through brokers, intermediaries, and outsourced QA. Kelker Pharma eliminates every layer between you and the people running the floor — faster answers, cleaner accountability, and a partner invested in your outcome, not just your purchase order.
