Instant Coffee (Powder, Half The Caffeine) (1 Tsp Dry)

Avoid consuming the instant coffee powder on an empty stomach; have it after or with a balanced meal instead.

Check the ingredient label and choose plain, unsweetened instant coffee with no sugar, maltodextrin, creamer, or flavored additives.

Use a smaller amount of coffee powder and dilute it with more water; reduce further if your glucose response persists.

Pair the coffee with protein and fat, such as plain Greek yogurt, eggs, cheese, or unsweetened soy milk, rather than drinking it alone.

Add fiber-containing low-starch foods alongside it, such as chia seeds, berries, or a small handful of nuts, if they fit your eating plan.

Try decaffeinated instant coffee or another preparation method, since caffeine itself can raise glucose for some people; compare responses under similar conditions.
