Ingredient profile
Potato Resistant Starch in SodaTide: 100 mg, the Research and the Cautions
Potato resistant starch is the second ingredient on the SodaTide label, at 100 mg per capsule, which is 0.1 g. Resistant starch is starch that skips digestion and is fermented in the large intestine. Studies used about 1 to 66 g a day, mostly maize starch. Weight evidence is weak, and no study tested SodaTide.

The ingredient01
What is potato resistant starch in SodaTide?
Potato resistant starch is starch from potato that resists digestion in the small intestine. SodaTide prints it as "Potato (Resistant Starch) (tuber)", 100 mg per capsule.
Resistant starch travels mostly intact to the colon, where gut bacteria ferment it into short-chain fatty acids (Harvard Health, Resistant starch). Because it feeds those bacteria, it counts as a prebiotic (Harvard Nutrition Source, Fiber).
The label does not say which type of resistant starch the powder is, or whether the starch is raw. We cannot say either.
| Name on the label | Potato (Resistant Starch) (tuber) |
|---|---|
| What it is | Potato (Solanum tuberosum) starch that resists digestion in the small intestine |
| Place on the panel | 2 of 3 |
| Amount per capsule | 100 mg per capsule (printed) |
| What research looked at | Trials of resistant starch (often raw potato starch in gram doses) on blood sugar, fullness and gut bacteria |
| Evidence level | Limited: small trials at gram doses; weight evidence limited |
| What it is called | Prebiotic starch |
| Main caution | Gas and bloating, mostly when the dose is large or started fast; the printed 100 mg is 0.1 g. |
The amount02
How much resistant starch is in one SodaTide capsule?
One capsule holds 100 mg, which is 0.1 g. That is the middle line on the panel, between 211 mg of inulin and 36 mg of probiotic blend.
People in the United States eat about 5 g of resistant starch a day by one estimate (Cleveland Clinic, Resistant starch), and about 4 g by another (Harvard Health, Resistant starch). Studies have used about 1 to 66 g a day (Baptista 2024, Resistant starch narrative review). The table sets the label next to those numbers. It does not compare SodaTide to a study dose, because the label amount is milligrams and trial doses are grams.
| Item | Grams a day |
|---|---|
| SodaTide, 1 capsule (printed) | 0.1 g |
| Typical US intake | About 4 to 5 g |
| Range used in studies | About 1 to 66 g |
| Starch type, source form and grade in the capsule | Not printed |
That gap does not make the capsule safe or unsafe. It means study results cannot be copied onto it.
The types03
Is potato starch a resistant starch, and which type is it?
Raw potato starch is a resistant starch of the type called RS2. A potato that is cooked and then cooled holds a different type, RS3.
Researchers sort resistant starch into five types, RS1 to RS5. RS2 is raw granular starch, found in raw potatoes and green bananas (Baptista 2024, Resistant starch narrative review). Cleveland Clinic describes type 3 as formed when starchy foods are cooked, then cooled, and says most people do not eat raw potatoes or unripe bananas (Cleveland Clinic, Resistant starch).
Cooling gives only a small lift. Russet potato goes from 3.1 to 4.3 g per 100 g when chilled, and a dietitian quoted by Harvard Health calls the effect "probably modest at best" (Harvard Health, Resistant starch). Our potato starch guide covers raw, cooked and capsule forms.
The research04
Does potato resistant starch help blood sugar or weight?
Some research points to lower blood sugar, and the weight evidence is weak. Neither was tested on this capsule.
Harvard Health says some research suggests more resistant starch may lower blood sugar and insulin, particularly in people with diabetes or obesity, and describes no studies (Harvard Health, Resistant starch). A narrative review found lower after-meal glucose and, from about 6 to 40 g a day, lower fasting glucose. It also found a small weight drop in one analysis, mainly in people with type 2 diabetes, and no significant BMI change in another (Baptista 2024, Resistant starch narrative review).
That review says most of the evidence is RS2 from high-amylose maize, not potato. It also notes high heterogeneity, and two authors work for a starch-ingredient company (Baptista 2024, Resistant starch narrative review). The NIH weight-loss supplement review has no section on resistant starch (NIH ODS, Dietary Supplements for Weight Loss (health professional)).
- Chicory Root InulinLimited
Limited: small trials at gram doses; weight effects small or mixed. Small trials of inulin-type fibre on appetite, weight and gut bacteria; most used several grams a day. (Cleveland Clinic, Inulin) (WebMD, Inulin: Uses and Risks) (Harvard Nutrition Source, Fiber) (Kunnackal John 2018, Gut microbiome diet and weight meta-analysis)

Limited: small trials at gram doses; weight evidence limited. Trials of resistant starch (often raw potato starch in gram doses) on blood sugar, fullness and gut bacteria. (Cleveland Clinic, Resistant starch) (Harvard Health, Resistant starch) (Baptista 2024, Resistant starch narrative review)
- Probiotic BlendVery limited
Very limited for these three names and for weight. Probiotic effects depend on the exact strain; studies of other strains looked at weight and gut symptoms. (NCCIH, Probiotics: Usefulness and Safety) (NIH ODS, Probiotics (health professional)) (ISAPP, Decoding a Probiotic Product Label) (Kunnackal John 2018, Gut microbiome diet and weight meta-analysis) (Cleveland Clinic, Probiotics and weight loss)
Bubbles show how much human research the linked sources describe for the uses the front of the bottle implies: appetite, metabolism and digestion. From 0 (none found) to 5 (strong). None of it tested SodaTide, and research on an ingredient is not proof that a product works at the printed amount.
Side effects05
Does resistant starch cause gas and bloating?
It plausibly can, because it is a fermentable fiber, but the resistant starch sources we read did not measure it. Treat it as the general rule for fiber, not a finding about this capsule.
Gas forms when bacteria break down carbohydrate that reaches the large intestine, and too much fiber can increase gas for some people (NIDDK, Gas in the Digestive Tract: eating, diet, nutrition). A sudden big rise in fiber can cause bloating and cramping, and Mayo Clinic says to add fiber slowly over a few weeks with plenty of water (Mayo Clinic, Dietary fiber).
Take the capsule with the 8 oz. glass of water the label asks for. Stop and call a clinician for severe belly pain, blood in the stool, black stools or repeated vomiting.

Can you take potato resistant starch with diabetes medicine?
Ask your doctor or pharmacist first. We could not find a source on resistant starch with diabetes medicine, so we cannot say how the mix behaves.
Insulin, sulfonylureas and meglitinides can cause low blood sugar, and skipped meals and fasting are causes (NIDDK, Low Blood Glucose (Hypoglycemia)). For most supplements there is no evidence of benefit for diabetes, and a supplement should never replace medical care (NCCIH, Diabetes and Dietary Supplements).
Pregnant or nursing, under 18, a known condition, or any medicine: the label says to consult a physician. Keep taking every prescribed medicine, and tell every provider about supplements before surgery (ASA, Herbal and Dietary Supplements and Anesthesia).
The FDA warns that weight-loss products are often found with hidden drugs (FDA, Weight Loss Product Notifications). We found no public test, FDA notice or warning letter for SodaTide. Absence from a list proves nothing.
Reading the bottle07
What should you check about the potato line on your bottle?
Check the name, the milligrams and the missing details. The line reads Potato (Resistant Starch) (tuber), 100 mg, with no Daily Value.
- No starch type (RS2, RS3 or other) is named.
- No statement of raw, heated or processed starch appears.
- The other ingredients are hypromellose, microcrystalline cellulose, magnesium stearate and silica.
The label facts page types out the panel. The other two lines are chicory root inulin and the probiotic blend.

SodaTide questions people ask
How many grams of resistant starch are in SodaTide?
One capsule holds 100 mg, which is 0.1 g, as the label prints it. That is far below the 1 to 66 g a day used in studies, though a gap alone says nothing about safety.
Is the potato starch in SodaTide raw?
The label does not say. It prints Potato (Resistant Starch) (tuber) and no starch type or processing. Raw potato starch is RS2, but we cannot tell which type the capsule holds.
Can resistant starch lower blood sugar?
Some research suggests it may, mainly in people with diabetes or at risk, at grams a day. Those studies did not test SodaTide, and nobody should adjust diabetes medicine because of a supplement.
Is potato resistant starch a prebiotic?
Yes, in the usual sense. It reaches the large intestine, where bacteria ferment it into short-chain fatty acids, so it feeds gut bacteria. Harvard calls it a soluble, fermentable fiber.
Is there a recommended daily amount of resistant starch?
No. Harvard Health says there is no official recommendation. US intake is around 4 to 5 g a day, and one 2020 study's authors suggested 15 g a day.
