When it comes to your health and wellness, trust is everything. You want to know that the supplements you take are safe, effective, and made with the highest standards. At Earth’s Splendor, we understand this deeply. That’s why every bottle, packet, and gummy we produce is backed by over 53 years of expertise and cutting-edge science at Contract Pharmacal Corp. (CPC), a leader in pharmaceutical and supplement development.

But what exactly happens behind the scenes? How do we guarantee the quality and potency of every product that carries our name? Step inside our lab to see the rigorous processes and dedication that ensure your supplements deliver real benefits, every time.

At Earth’s Splendor, we don’t just follow industry standards—we set them. Our commitment to quality, safety, and potency is built into every step of the journey, from raw material sourcing to the final product you hold in your hands.

Here’s how we ensure that every supplement meets the highest standards of excellence.

1. Raw Material Identification

Where quality begins.

Every ingredient is tested the moment it enters our Long Island, NY facility. In our in-house labs, analytical chemists carefully verify the identity, purity, and potency of raw materials. Each batch undergoes screening for contaminants such as heavy metals, pesticides, and harmful microbes before it ever makes it to the production line. This thorough process ensures that only verified, high-quality materials are used in your supplements, providing you with the confidence that every product meets the highest safety and quality standards.

2. In-Process Validation

Precision at every stage.

During manufacturing, we conduct ingredient accuracy checks, validate formulations, and inspect every batch for capsule, label, or packaging inconsistencies. This means that every step of the production process is closely monitored by our dedicated quality assurance team. From color and consistency to blend uniformity and fill weights, nothing is left to chance. We ensure that the ingredients are measured correctly, that the blend is even throughout, and that each capsule or packet meets the strict specifications we set. Our stringent quality assurance protocols uphold our cGMP certification, providing you with confidence that every product you use has been manufactured with precision and care.

3. Finished Product Testing

The Final Seal of Quality

Before a product is approved for sale, we test the final batch for identity, potency, purity, and microbiological safety. This crucial step ensures the product is safe, effective, and that all ingredients meet label claims. Our thorough testing includes multiple stages of analysis to detect any potential contamination, such as traces of lead, arsenic, yeast, mold, and more. Every finished lot receives a Certificate of Analysis (COA), a formal document that confirms its safety, quality, and consistency. This process provides you with peace of mind, knowing that what you see on the label is exactly what’s in the bottle.

Bonus: Stability Testing

Consistency you can count on.

Every first production lot goes through 11 comprehensive tests, including 3 tests for release and 8 additional tests for stability. These rigorous evaluations ensure that your supplements maintain their strength, safety, and effectiveness throughout their entire shelf life, all the way to the expiration date. The testing process follows established ICH guidelines, a global standard for pharmaceutical quality control, to guarantee accuracy and consistency. This detailed approach ensures that what’s listed on the label is exactly what you’ll get from the first dose to the last.

Innovation That Sets Us Apart

At Earth’s Splendor, innovation happens at every level, from the thoughtful design of our product formulations to the rigorous testing performed in our state-of-the-art labs. Our team of analytical chemists plays a central role in this process, applying advanced techniques and scientific expertise to ensure every product meets the highest standards of quality and safety.
