SupreP (the sodium picosulfate/magnesium citrate/ascorbic‑acid bowel‑prep) comes as a clear liquid that you drink over the course of a few hours. Most people describe it as having a “bitter‑sour” flavor. The bitterness mainly comes from the magnesium citrate, while the ascorbic acid (vitamin C) adds a tart, acidic note. The manufacturer does add a small amount of sugar to help mask the taste, so it can taste a bit sweet at the beginning, but overall it’s still noticeably unpleasant to many people.
Because the taste is often described as “unpleasant” or “bitter‑sour,” some people mix the solution with a flavored drink (like fruit juice, sparkling water, or a sports drink) or even a flavored ice‑cream mix to make it easier to swallow. Others just take it straight up, sometimes using a straw or a large glass to help with swallowing.
If you’re worried about the taste, you might try:
- Adding a splash of lemon or lime juice (just a few drops) to increase the tartness and mask the bitterness a bit.
- Mixing it with a small amount of your favorite flavored drink (but avoid high‑calorie or sugary beverages if you’re trying to keep the prep as light as possible).
- Using a straw or a large glass so you can swallow it in one go.
Ultimately, the taste is pretty typical for bowel‑prep solutions—bitter, sour, with a faint metallic hint. Most people find that once the first sip is down, the rest of the liquid is easier to swallow, especially if you’re mindful of the flavor or use a mixer.
