A declared dietary-fiber amount and the weight of a prebiotic ingredient blend are different measurements. Core liquid lists 4 g dietary fiber; GI UltraMAX lists a 2,900 mg Prebiotic Fiber Blend. Converting the latter to 2.9 g changes its unit, not its meaning—it remains blend weight. [1] [2]
The conversion is easy; the interpretation is the important part
2,900 mg ÷ 1,000 = 2.9 g. That is a correct unit conversion, but it does not turn the entry into a 2.9 g dietary-fiber declaration. Copy the entire label description beside the number. To compare dietary fiber, find a dietary-fiber entry for each product or ask the manufacturer for the missing information.
Both entries are useful. The trick is to keep the label’s description attached to the amount, especially when comparing a daily multinutrient liquid with a more specialized digestive-support powder.
Put the two entries on the same page
| What to read | Comprehensive Core liquid quart | GI UltraMAX powder |
|---|---|---|
| Serving basis | 1 fl oz (2 tablespoons); 32 servings | 1 scoop; 30 servings |
| Dietary Fiber nutrient line | 4 g, 14% Daily Value | No separate total Dietary Fiber line on the posted panel |
| Specific fiber entry | Organic digestion-resistant prebiotic fiber: 200 mg | Prebiotic Fiber Blend: 2,900 mg |
| Other ingredients within that blend | The 200 mg entry is not the total dietary fiber declaration | Glucomannan 1,000 mg; resistant arabinogalactan 600 mg; organic prune 500 mg; digestion-resistant fiber 500 mg; organic fenugreek 300 mg |
The GI UltraMAX ingredients add up: 1,000 + 600 + 500 + 500 + 300 = 2,900 mg, or 2.9 g of the listed blend. The arithmetic confirms the blend total. It does not establish that every milligram is declarable dietary fiber.
Why blend mass and dietary fiber can differ
Dietary fiber is a defined nutrition-label category. FDA’s definition covers intrinsic plant fibers and qualifying isolated or synthetic nondigestible carbohydrates. A plant ingredient’s entire weight is not automatically its dietary-fiber content. [3]
Think of a fictional ingredient mix containing 1 g of a fruit powder. “1 g fruit powder” identifies how much powder was added. It does not tell you how much of that gram is fiber, sugar, moisture or other material. A named fiber blend can likewise contain ingredients whose full weights should not simply be relabeled as grams of total dietary fiber.
This distinction also explains why Comprehensive Core’s 200 mg prebiotic-fiber entry and its 4 g Dietary Fiber line can coexist. They identify different things. The 200 mg entry is 0.2 g; it is not a substitute for the separately declared 4 g nutrient amount. Nor should it automatically be added to that nutrient line to report 4.2 g.
Use Daily Value only with the matching nutrient amount
The general U.S. dietary-fiber Daily Value for adults and children age four and older is 28 g. Comprehensive Core’s declared 4 g gives 4 ÷ 28 × 100 = approximately 14%, consistent with its posted panel. [4]
Dividing GI UltraMAX’s 2.9 g blend by 28 g would give about 10.4%. That is mathematically possible but answers the wrong labeling question. Without a total dietary-fiber declaration or manufacturer documentation establishing that amount, it should not become a “10% Daily Value of fiber” claim.
Decide what you actually want to compare
For a dietary-fiber total, compare the Dietary Fiber nutrient line on the same serving basis. For a particular prebiotic ingredient, compare its named preparation and disclosed amount. For the complete formula, consider the rest of the ingredients and directions rather than using one blend total as a score.
The GI UltraMAX label instructs mixing a scoop into 4 oz of liquid, drinking promptly because it thickens, and immediately following with 8 oz of water. It also identifies colostrum and contains an allergy caution. Read those directions and your own container before use; they matter more than making the powder’s blend number resemble the liquid’s nutrient line. [2]
