Agave NectarSweetener

Agave nectar is ~70–90% fructose by composition (vs sucrose's 50% and high-fructose corn syrup's 55%). Low glycemic index is a fructose artifact — fructose bypasses insulin-mediated metabolism and is preferentially shuttled to hepatic de novo lipogenesis. Chronic high-fructose intake is associated with hepatic steatosis, insulin resistance, and adverse lipid changes (Stanhope 2009 RCT). The 'natural' / 'healthier than sugar' marketing positioning contradicts the metabolic profile. Per brand voice: this is a clearer case than most of marketing-vs-science divergence.

Rice FlourFiller

Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.

Rice ExtractFiller

Rice-based ingredients carry risk of inorganic arsenic contamination. Vague labeling — 'rice extract' does not specify what is extracted or standardized. Used as a cheap filler with no supplemental benefit.

Tapioca DextrinCarrier

A starch hydrolysate from tapioca used as a carrier and flow agent

Guar GumThickener

Natural thickener derived from guar beans

Gum AcaciaBinder

Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
