At Jool, quality isn't just a promise—it's our foundation. From sourcing to packaging, we obsess over the details so you can feel confident in every capsule.

🌿 Sourced From Nature’s Purest Environments

We source our grass-fed beef liver and nutrient-rich oysters from New Zealand, a country known for its pristine waters, clean air, and rigorous animal welfare standards. New Zealand's remote location and strict environmental regulations make it one of the best places on earth to harvest organs and shellfish free from contaminants and pollutants.

🐄 100% Grass-Fed, Always

Our beef liver comes from cattle raised on open pastures and a 100% grass-fed diet, just as nature intended. This results in a richer nutritional profile, with higher levels of essential vitamins and minerals—and zero shortcuts.

🌊 Oysters from Clean, Cold Waters

Our oysters are harvested from the cold, clean coastal waters of New Zealand, far from industrial runoff and pollution. These waters are rich in natural minerals and nutrients, resulting in oysters that are exceptionally high in zinc, copper, selenium, and other trace elements essential for vitality and hormonal health.

🏭 Manufactured in the USA

While our ingredients come from NZ, we manufacture everything right here in the United States. Our facilities follow the highest standards for safety, purity, and potency. Every batch is tested to ensure what’s on the label is what’s in the bottle—nothing more, nothing less.

🍶 Packaged With Purpose

Most supplements come in plastic. Ours come in recyclable amber glass bottles—better for the planet, and better for preserving the integrity of our ingredients. The amber tint protects sensitive nutrients from light, helping maintain freshness and potency without synthetic preservatives.
