The verdict
L-Glutamine by Women's Best scores 100/100 in PlainFoodSafe's ingredient screening. We compared its 2 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 0 ingredients are flagged for caution. Its short parsed label begins L-glutamine, Kyowa Quality, so the useful next step is to inspect those few components directly rather than infer from the composite score. This is not a recall, allergy, medical, or dietary-safety determination.

Screening model notes
How Nutri-Score, NOVA, and list length read this record
Within the four-tier shelf-label framework this site publishes, the composite for this product falls in the highest band. That band is defined by a threshold on the derived score alone: it is where labels land once components carrying caution-or-worse registry ratings contribute little or nothing to the deduction. The band is a summary of what the screened registries return for the components that were parsed, so it inherits their coverage gaps — a component absent from both registries neither raises nor lowers the figure. The threshold and the weighting behind it are set out on the methodology page.
Nutri-Score is not defined for this product's category. The model excludes certain categories by design — among them plain waters, herbs, teas and coffees, and some single-ingredient products — rather than attempting a grade and failing. No nutritional band therefore accompanies the additive screen on this page, and its absence is a property of the category rather than a finding about this particular label. The registry screen below is unaffected by the exclusion and covers additive ratings as normal.
The declared list parsed into a small number of components. On a short list the registry screen covers close to everything the packaging declares, and any single matched component accounts for a correspondingly large share of the composite. Short lists also leave less room for parsing error, since there are fewer separators and qualifiers for the extraction to resolve.

How It Compares to Its Category
Among the 3,895 products we've scored in the Dietary supplements category, the average safety score is 93.5/100. L-Glutamine scores 6.5 points above that category average (100/100 vs. 93.5/100), so it is a comparatively strong pick for shoppers screening within that category specifically, rather than against the product catalog as a whole.

Ingredient-list length is a descriptive property of the label, not a safety rating. A longer list is not automatically worse and a shorter one is not automatically better; the count is shown so the label can be placed against a comparable population. The comparison here runs against the 2,658 Dietary supplements products we publish with a parsed label, not against the whole catalogue, because list length varies far more between categories than within one.
