Six Star Clean Protein Shake
by Six Star
Scores 80/100 on FDA SAFFA + CSPI ingredient analysis , with 2 flagged ingredients identified.
The verdict
Six Star Clean Protein Shake by Six Star scores 80/100 in PlainFoodSafe's ingredient screening. We compared its 41 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 2 ingredients are flagged for caution. The source parser split this into a very long 41-component record, beginning with Filtered Water, Protein Blend, Milk Protein Isolate. That density can include amounts and label fragments, so verify the physical label before relying on ingredient order or completeness. This is not a recall, allergy, medical, or dietary-safety determination.

What the Data Says About Six Star Clean Protein Shake
Six Star Clean Protein Shake by Six Star carries a composite safety score of 80/100, which we classify as "Caution" on our four-tier shelf-label framework.
Of the 41 ingredients parsed from this label, 15 are covered by a regulator or watchdog we screen against (Manganese Sulfate, Potassium Iodide, Sodium Hexametaphosphate and 12 others), with 14 carrying an FDA Substances Added to Food (SAFFA) status and 3 a CSPI Chemical Cuisine rating. The remaining 26 ingredients appear in neither registry, so they neither raise nor lower the score. Each additive rated caution-or-worse penalizes the composite. Product data originates from the OpenFoodFacts collaborative catalog; safety annotations come from federal regulators and the Center for Science in the Public Interest. This score is a transparent derived index we compute from that public data, not an official FDA rating or endorsement; see the Methodology page for the exact weighting.
Our scan identified 2 flagged ingredients in this product, components that at least one official source has classified as requiring caution, targeted avoidance, or further evaluation. Flagged ingredients are the items most likely to surface in FDA inspection findings, state-level ingredient bans, or outbreak-related recall notices, so the per-ingredient breakdown below is the most useful lens for anyone screening this product for a specific dietary concern.
On the NOVA processing scale, Six Star Clean Protein Shake is classified as Group 4 (Ultra-processed). NOVA measures industrial processing intensity rather than ingredient-level safety, so it complements the SAFFA and CSPI ratings: a product can be clean on additive flags but heavily processed, or lightly processed but carry individually flagged ingredients. Combining both lenses gives a fuller picture than either alone. The Nutri-Score grade of B reflects nutritional balance, calories, saturated fat, sugar, sodium versus fiber, protein, and produce content, which again is a distinct dimension from additive safety and worth weighing alongside the scores above.

How It Compares to Its Category
Among the 32,623 products we've scored in the Beverages category, the average safety score is 90.5/100. Six Star Clean Protein Shake scores 10.5 points below that category average (80/100 vs. 90.5/100), so it is a comparatively weaker pick for shoppers screening within that category specifically, rather than against the product catalog as a whole.
