Pre workout (1 piece)

Choose a stimulant-focused pre-workout with little or no added sugar, maltodextrin, dextrose, or highly processed carbohydrate blends.

Use a smaller serving or split the serving: take half 20–30 minutes before training and assess your glucose response.

Avoid taking pre-workout on an empty stomach; pair it with a small protein-and-fat snack such as plain Greek yogurt with a few berries or an egg with avocado.

If you need carbohydrates before training, choose slower-digesting options such as oats, lentils, chickpeas, apples, pears, or berries, and keep portions modest.

Mix powdered pre-workout with water rather than juice, sports drinks, or sweetened milk alternatives.

Track the specific product, serving size, timing, and workout intensity; if spikes persist, switch products and discuss recurring elevations with your clinician.
