Other Ingredients (8)

Titanium DioxideColorant

Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health 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.

Soy LecithinEmulsifier

Widely used emulsifier derived from soybeans

BeeswaxCoating

Natural wax produced by honeybees, used as a coating and binding agent in softgels and tablets

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

GlycerinHumectant

Sweet-tasting liquid used in soft capsules and liquids

Sodium Copper ChlorophyllinColor

Water-soluble semisynthetic chlorophyll derivative used as a green colorant

Purified WaterSolvent

Water meeting USP specifications used as solvent/vehicle in gummies and liquids

How to Take It

Best taken in the morning

Contains Caffeine, which is stimulating — keep it to the morning. What's in this is easier on the stomach taken with food.

With food
Keep it away from iron-rich meals
Space it a couple of hours from Iron

On the label

Directions: (Adult) As an addition to your reduced calorie diet and exercise plan, take two (2) liquid soft-gels in the morning and one (1) or two (2) in the afternoon 30 minutes before meals with a full glass (8oz) of water. If caffeine keeps you up at night, do not take this product in the evening since it contains natural caffeine.

The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.

General guidance based on the ingredients, not a substitute for the label or your doctor.
