Glucose SyrupSweetener
High glycemic load; source typically corn (generally gluten-free)
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.
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.
How to Take It
Best taken in the morning
The Tyrosine in it is what pulls this toward the morning. Take it with food — the potassium in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Tyrosine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from protein-heavy meals and high-oxalate foods like spinach
Space it a couple of hours from Iron and Zinc
On the label
As a dietary supplement, take 1 scoop mixed in 8–10 oz water, 20 minutes before intense exercise, or as directed by a health professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
