Creatine (Scivation) (1 Serving) and Whey Protein (Ultimate Nutrition) (1 Serving)

Use plain, unflavored creatine monohydrate mixed with water; avoid flavored powders, gummies, or pre-workouts that may contain sugars or fast-digesting carbohydrates.

Choose an unsweetened whey isolate with minimal ingredients and no added sugar; check the nutrition label for carbohydrate content per serving.

Take the shake alongside a meal containing protein, fat, and fiber rather than on an empty stomach; options include eggs, avocado, nuts, or plain Greek yogurt.

Blend the whey with unsweetened milk alternatives, water, chia seeds, or ground flaxseed instead of fruit juice, honey, or sweetened milk.

Reduce the serving size or split it into two smaller servings taken at different times, then compare your glucose response.

Review your glucose readings against the ingredient list and timing; if rises persist with plain creatine and unsweetened whey, discuss the pattern with a clinician or dietitian.
