Lead
0.79 mcg per serving
Moderate

A moderate level of lead — elevated enough to be a real sourcing concern; cleaner-tested options exist.

Independent third-party testing.

Cadmium
1.85 mcg per serving
Moderate

Detected at a moderate level — a meaningful fraction of health-based exposure limits. Worth factoring in if this product is used regularly. Cadmium is an IARC Group 1 carcinogen that accumulates in the kidneys over a lifetime.

Consumer Reports January 2024 detected 1.85 mcg cadmium per serving.

Arsenic
0.5 mcg per serving
Low

A low level of arsenic — present but modest; a sourcing-quality note rather than a safety concern at typical intake.

Consumer Reports January 2024 detected 0.5 mcg arsenic per serving.

Mercury
not detected
Not detected

Not detected — below the laboratory's detection limit. This is the strictest possible result: no measurable amount was found.

Consumer Reports January 2024 reported mercury below the lab's threshold of detection — no mercury measurable in this product.

Vegetable Oil (Sunflower, Canola, and/or Soybean Oil)
Very Bad

Refined seed/soybean oil blend high in inflammatory omega-6 linoleic acid. Heavily processed with hexane extraction and the unspecified blend (and/or soybean) hides what's actually in the bottle.

Natural Flavors
Bad

Proprietary flavor blend; can hide dozens of synthetic aroma chemicals and phthalate carriers under FDA trade-secret rules.

Lecithin (Sunflower, Canola, and/or Soy Lecithin)
Bad

Unspecified-source emulsifier; the 'and/or soy' wording allows GMO soy lecithin without disclosure on the front label.

Salt
Neutral

Sodium for flavor balance; minimal contribution to total sodium intake.

Sodium Polyphosphate
Bad

Industrial phosphate emulsifier/preservative. Excess phosphate intake from processed foods is associated with cardiovascular and kidney concerns.

Trisodium Phosphate
Bad

Strongly alkaline pH adjuster (also used as an industrial degreaser). Used here as a stabilizer; raises total phosphate load.

Gellan Gum
Neutral

Microbial-fermentation-derived thickener; inert and safe at typical concentrations.

Sucralose
Bad

Chlorinated artificial sweetener linked to disruption of gut microbiome, potential insulin response issues, and generation of harmful chlorinated compounds during metabolism.

See more about Sucralose →
Invert Sugar
Neutral
