The Casa de Sante Purity Promise

The Casa de Sante Purity Promise

Because your health deserves proof — not promises.

At Casa de Sante, we believe that wellness starts with trust. That's why we created the Purity Promise — our commitment to full transparency, third-party lab testing, and ingredient integrity in every formula we make.

Our products are tested for heavy metals and purity before they reach your hands — and we share every result publicly.

🧪 Our Testing Process

1

Third-Party Laboratory Verification

Casa de Sante protein powder is tested by independent, ISO-accredited labs (Summit Labs and Merieux NutriSciences). These labs verify levels of lead, arsenic, cadmium, and mercury — ensuring they fall well below Consumer Reports and FDA safety limits.

2

Evidence-Based Standards

We benchmark our results against:

  • Consumer Reports (CR) Daily Lead Limit: 0.5 µg/day
  • FDA Interim Reference Level (IRL): 8.8 µg/day
  • NSF/ANSI Standard 173: ≤10 µg/day

By comparing our lab results directly to these thresholds, we give you a clear view of what "clean" actually means.

3

Ingredient Transparency

We disclose our results because informed customers make better health choices. Each Certificate of Analysis (COA) below includes:

  • Batch number
  • Date tested
  • Heavy metal results (µg/serving)
  • Laboratory name

💚 Our Purity Heroes

🔍 Why Purity Over Popularity

The supplement industry often rewards taste and marketing over safety. Casa de Sante was founded to change that. Our guiding principle is simple:

We don't chase popularity. We prove purity.

We don't use artificial flavors or fillers — only clinically backed ingredients tested for quality and digestibility. Our Low FODMAP and ProHydrolase® enzyme blend ensure every serving supports gut health, not inflammation.
