Tribulus

Fruit powder is the ground plant material, and the label states its weight. An extract is concentrated from the plant, so the label may also give an extract ratio or the percentage of a marker compound it is standardised to. Milligrams of powder and of extract are not the same amount of raw material, so compare strengths within the same type.

Not necessarily. A number in a product name may refer to a daily serving, a blend or the whole pack. The nutrition table states the amount per serving and the number of capsules in a serving, which is what to compare. Dividing the capsules in the pack by the serving shows how many servings a pack holds.

Both ingredients appear in the ingredient list in descending order of weight, and the nutrition table usually gives an amount for each. To compare the tribulus alone, look at its line rather than the total weight of the capsule. Titles marked vegan name a plant-based capsule shell.
