Questions.

IGNITE is built for the 30–60 minute window before training. REBUILD is built for the 30-minute window after. Different ingredients, different timing, different purpose. They're designed as a system.

No. Both bars are around 175 calories and 12–15g protein. This is not enough to replace a meal. They're functional supplement bars designed for specific windows around training. Eat real food before and after.

No. Protein bars compete on grams of protein per calorie. Thirdwind Fuel competes on timing and micronutrients. Protein is in both bars as a functional bridge, not the headline ingredient.

Yes, but you're leaving half the system unused. IGNITE handles the pre-training window, REBUILD handles recovery. The Window Bundle gets you both — see pricing on the product page.

Store cool and dry. Water activity tested in a laboratory at 0.55. Shelf stable without refrigeration. Avoid extended exposure to heat above 85°F. Best within 90 days of purchase.

Exercise physiology research has identified specific windows around training where the body is most receptive to certain nutrients. Before training, blood flow increases and electrolytes are most efficiently absorbed. After training, a short window exists where anti-inflammatory compounds and protein are most effective for recovery. Miss the window and those nutrients work at a fraction of their potential.

Most bars include micronutrients as label decoration — trace amounts that don't reach functional doses. Every ingredient in IGNITE and REBUILD is dosed for effect, not appearance. See The Science page for the full breakdown and citations.

No, we use a decaf espresso blend for athletes with later games and training schedules.

The Science page has the full ingredient breakdown with peer-reviewed citations for each compound. Every formulation decision is referenced.
