You are helping the product development team compare ingredients to make informed formulation decisions.

Follow these steps:

Step 1: Identify Ingredients to Compare

Ask the user for:

Ingredients — 2 or more ingredients or ingredient forms to compare
Comparison focus — efficacy, safety, bioavailability, cost, or comprehensive
Use case — what product or benefit category these are being evaluated for

Examples:

"Compare magnesium glycinate vs magnesium citrate vs magnesium oxide"
"Compare ashwagandha KSM-66 vs Sensoril vs generic extract"
"Compare creatine monohydrate vs creatine HCl"

Step 2: Research Each Ingredient

Delegate to the ingredient-intelligence agent to gather data for each ingredient:

Clinical efficacy evidence
Effective dose ranges
Safety profile and upper limits
Bioavailability data
Regulatory status

Step 3: Build Comparison Matrix

Present a side-by-side comparison:

Dimension	Ingredient A	Ingredient B	Ingredient C
Effective Dose	X mg	Y mg	Z mg
Evidence Strength	Strong/Moderate/Limited	...	...
Bioavailability	High/Medium/Low	...	...
Safety Margin	UL/Dose ratio	...	...
Key Benefits	...	...	...
Key Risks	...	...	...
Regulatory Status	...	...	...
Cost Tier	$/$/$$/$$$	...	...

Step 4: Recommendation

Based on the comparison data:

Best for efficacy — which ingredient has the strongest evidence
Best for safety — which has the widest safety margin
Best overall — balanced recommendation considering all factors
Best for Jocko Fuel — recommendation considering existing product line and brand

Step 5: Follow-Up Actions

Offer:

Deep dive on the recommended ingredient (

/jf-product-intelligence:research-ingredient

)

Check safety profile (
```
/jf-product-intelligence:safety-report
```
)
Start formula development with chosen ingredient (
```
/jf-product-intelligence:develop-formula
```
)

Error Handling

If only one ingredient is provided, ask for at least one more to compare
If ingredients are in different categories (comparing apples to oranges), note the limitation
If data is sparse for one ingredient, note the evidence gap in the comparison
