Other Ingredients (7)
FructoseSweetener
Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.
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.
CreamerTexturizer
Composition varies; may contain hydrogenated oils, added sugar, and emulsifiers.
Decaffeinated Coffee PowderFlavor
Ground decaffeinated coffee used as a natural flavoring
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.
Soy Protein IsolateFood
Purified protein isolated from soybeans.
Calcium CarbonateBuffer
Common calcium salt used as a buffering agent, filler, or mineral fortification in supplements
How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins D and E in it absorb poorly without one.
With a meal containing fat
Keep it away from high-oxalate foods like spinach, medication and mineral supplements
Space it a couple of hours from Iron
On the label
Mix one scoop (just over two tablespoons) of Secure in 6 to 12 ounces of water, juice, non-fat milk, smoothie, etc. Use more or less liquid to achieve the desired flavor intensity.
General guidance based on the ingredients, not a substitute for the label or your doctor.
