Why Many Kanna Products Fall Short

Kanna is a botanical material, and its alkaloid content can vary depending on plant chemotype, cultivation conditions, and processing methods. Without standardization, the labeled milligram amount of “kanna” does not reliably reflect the quantity of active alkaloids present.

When a product does not disclose its alkaloid percentage, it becomes difficult to meaningfully compare that formulation to published human research.

Quality Standards That Matter

1. Alkaloid Standardization on the Label

Look for a clearly stated extract dose and alkaloid percentage, such as: “30 mg Sceletium tortuosum extract, standardized to X% total alkaloids.”

Milligram weight alone does not reliably reflect active alkaloid content without standardization.

2. Third-Party Certificate of Analysis (COA)

A batch-specific COA should confirm alkaloid content and screen for heavy metals, pesticides, and microbial contamination. Independent third-party testing supports transparency and quality control.

3. cGMP-Compliant Manufacturing

Production in a facility that follows current Good Manufacturing Practices (cGMP) helps support consistency, documentation, and quality oversight.

4. Transparent Formulation Oversight

Disclosure of qualified professional involvement in formulation may support appropriate dosing decisions and product integrity.

5. Transparent Sourcing

Clear disclosure of botanical origin and cultivation practices supports traceability and authenticity.

6. No Undisclosed Proprietary Blends

Be cautious of proprietary blends that obscure the exact amount of kanna provided, making it difficult to assess potency.

How SoulBloom Approaches Quality

SoulBloom is formulated with the following quality considerations:

25 mg standardized Sceletium tortuosum extract per serving (5% total alkaloids)
Batch-specific third-party Certificate of Analysis (COA) available
Manufactured in a cGMP-compliant facility
Transparent formulation oversight
Disclosed South African botanical sourcing
Designed for sublingual use to support efficient absorption

Potential Red Flags

Be cautious of products that:

Do not disclose alkaloid percentage
Do not provide a batch-specific third-party COA
Hide kanna within a proprietary blend
Make explicit medical claims (e.g., “treats anxiety” or “cures depression”)
Provide minimal transparency about sourcing or manufacturing

FAQ

Is more expensive always better?

Not necessarily. Price alone is not a reliable indicator of quality. Transparency around standardization, testing, and manufacturing practices is more informative than cost alone.

What does “full-spectrum” mean?

Full-spectrum extracts preserve multiple naturally occurring alkaloids rather than isolating a single compound. Published human trials have evaluated standardized extracts containing a range of alkaloids.

How do I read a COA?

Verify that:

The batch number matches your product
Alkaloid content aligns with the labeled claim
Heavy metals and contaminants are within acceptable limits
The testing laboratory is identified
The report is recent and batch-specific
