SucraloseSweetener
Dose context matters. As a trace excipient in a tablet coating or capsule, the amount is minimal and not a meaningful concern. The evidence below applies to the gram-level intakes typical of sweetened protein powders, pre-workouts, and drink mixes: a 2022 human trial (Suez et al., Cell) showed sucralose disrupts gut bacteria and worsens blood sugar control in healthy adults, and a 2023 study (Schiffman et al.) found that sucralose-6-acetate — a compound formed when sucralose is digested — was genotoxic to human cells in vitro. It remains an artificial sweetener with no nutritional purpose.
Natural and Artificial FlavorsFlavor
The 'artificial' component means synthetic chemicals are used, but the exact compounds are proprietary and not disclosed on the label. If you have sensitivities or allergies, you cannot verify what's in it. Products using only natural flavors are more transparent.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Citric AcidAcidulant
Natural acid derived from citrus fruits
Malic AcidAcidulant
Naturally occurring organic acid found in apples, used as a flavor enhancer and acidulant in supplements
How to Take It

Space it a couple of hours from SAMe
On the label
As a dietary supplement, mix one (1) scoop of 1st Phorm Essential Amino Acids in eight (8) ounces of water and drink pre-workout, intra-workout, or throughout the day when adequate protein sources are unavailable.
Do not combine with St. John's Wort
Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
General guidance based on the ingredients, not a substitute for the label or your doctor.
