ErythritolSweetener
Witkowski et al. 2023 (Nature Medicine, PMID 36849732) reported elevated plasma erythritol associated with major adverse cardiovascular events (MACE) in two cohorts (n=4,000+), with in-vitro and ex-vivo evidence of enhanced platelet aggregation. Replication is ongoing; FDA and EFSA have not changed their safety positions, but the signal is real and the additive is purely cosmetic. Better-established concern: GI tolerance — single doses above ~50 g cause osmotic diarrhea. Lower threshold for children.
MaltodextrinBinder
Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.
Beet ColorColorant
Natural red-pink colorant from dehydrated beets or beet juice; the pigment is betanin
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Citric AcidAcidulant
Natural acid derived from citrus fruits
Guar GumThickener
Natural thickener derived from guar beans
Malic AcidAcidulant
Naturally occurring organic acid found in apples, used as a flavor enhancer and acidulant in supplements
How to Take It
Best taken in the morning
Morning or early afternoon only — caffeine within 8 hours of bed measurably disrupts sleep.
With or without food
