I've used it plain and mixed with other drink mixes. This stuff easily dissolves in water and I have never had a problem with "sediment". I currently use Carbopro mixed with Gatorade (Gatorade used sparingly as to just add some flavor). There is no protein content, so if you're one who also supplements as such, you'll need to use a product that offers some (along with the Carbopro).
As per the SportsQuestDirect.com web sight:
CARBO-PRO: (C6H10O5)n.H2O
CARBO-PRO is a nonsweet (nuetral flavor) glucose polymer that consists of D-glucose units linked primarly by alpha-1-4 bonds, having a Dextrose Equivalency of less than 16 (high molecular weight). It is low on the Glycemic Index (20) in comparison to sugar (100).
Its a white powder prepared by enzymatic hydrolysis (patented process) of grains (corn/barley/rice) with safe and suitable enzymes. Its safe for direct human consumption.
CARBO-PRO is agglomerated to create dustless, low-density granules with good physical strength and free flowing properties. It exhibits excellent dispersibility and dissolution characterisitcs.
High-performance liquid chromotograpy analysis determines that the average degree of polymerization, i.e., the number of glucose units joined in the molecule is 6.2. The average theoretical molecular weight is 1,000. The high molecular weight helps in quick absorption.
Low Solution Osmolality: CARBO-PRO has a perfect balance of caloric concentration and osmolality. The dextrose equivalency of CARBO-PRO is 16 therefore it is low in osmolality even up to 15% to 20% solution in water (200 to 220) lower than body fluid osmolality (280 to 300). For example the osmolality of sugar at 15% to 20% solution in water is approximately 800. Therefore sugar at this concentration is too hard on the stomach. Relative to sugars, CARBO-PRO provides higher caloric density without exceeding osmotic balance.
The total complex carbohydrate content of CARBO-PRO is 94.5%.

Recommended Use:
As a dietary supplement, mix two scoops (2 oz.) or (57 gm) in 20-24 oz. of water and drink it during exercise activity.
Note: Diabetics should consult their physician before use.
As for Vantage, I have found it helpful as a "phosphate loading" supplement, leading up to a major race (1/2 IM or IM).
Hope this helps...
