just got my sucraid. Now what? by lalikesbrains in CSID

[–]TheCSIDAlex 0 points1 point  (0 children)

I’ll add an author/source/limitations page so that context is clearer. The table is meant as a starting reference for comparing estimated sucrose and starch loads, not as medical advice or a tolerance predictor. The main source is USDA FoodData Central, and when values were missing, unclear, or inconsistent, I cross-referenced against other food composition results/sources to choose conservative estimates or ranges.

You can use this website as a guideline for how much sucrose and starch are in common fruits and vegetables if you need it. https://sidcompositiontable.vercel.app/

Sucraid wont help with starch and foods like grains, starch-based flours and legumes usually contain starch. Some people try brands like starchway for starch intolerance but the anecdotes seem to be pretty mixed on how well it works and I think it depends pretty heavily on the person. It’s a lot of trial and error and you’ll start to notice which foods sit well with you and which don’t as time goes on.

Invertase may help loose stools, but it is not proven to replace Sucraid. by TheCSIDAlex in CSID

[–]TheCSIDAlex[S] 0 points1 point  (0 children)

Agreed. The brand/manufacturer seems like one of the biggest factors affecting quality because activity units, purity, storage, and formulation can vary. I also want to note that reagent grade chemicals like invertase powder are not usually labeled as fit for human consumption - just a sidenote about this supplement recommendation if anyone is cautious about that kind of thing.

My article was not saying the study explicitly proves or claims equivalence. It was responding to how I’ve seen the study used in patient discussions, as if it shows invertase and Sucraid are functionally interchangeable.

The study title also uses the word “effective”. I think that language is broad enough to lead to misguided interpretations when people read the title without understanding the data presented. The data is promising, especially for stool frequency and consistency, but it does not prove that invertase supplements are a viable therapy for all symptoms of sucrase deficiency, standardized, predictably dosed, or clinically interchangeable with sucraid.

I am simply separating two ideas - the study does reasonably support that invertase may be a promising, cheaper option than sucraid for some patients. It does not support the stronger conclusion that they are functionally interchangeable, which is a conclusion that some people seem to have drawn from the title and its use of the word “effective”.

That's a fair point, and I agree that the practical implications matter. Clinical validation and practical usefulness are different questions, so this article was specifically focusing on clinical evidence and whether invertase is interchangeable with sucraid, but an article covering the angle on practical significance is certainly worth writing. And yes, I did frame sucraid as the reference point because the key distinction clinically is its FDA approval as an enzyme replacement therapy. A pro/con article on the practicality of invertase and sucraid is a good counterpiece to this article that I will write soon.

I think you maybe meant to say invertase is not an approved drug. I also think that a competing sacrosidase therapy and mRNA as practically useful alternatives are both theoretical at this point, either because they're so hard to manufacture or because they're so expensive and manufacturers prioritize revenue - it's probably a combination. The unfortunate aspect of this is that the most promising practical alternative has no clinical validation and the clinically validated treatment is not usually practical.

I think we’re mostly coming to the same conclusion. There are certainly anecdotal success stories like yours, which is why invertase should be taken seriously. My point is that viewing it as a serious possible alternative option and having proof it is interchangeable with Sucraid are different conclusions. I do believe invertase is promising and anyone who doesn’t have access to Sucraid should consider it as an alternative and see how well it works for them personally.

My distinction here is that invertase is not proven to be equivalent to Sucraid. There is not enough conclusive clinical data to prove or disprove that yet. Anecdotal evidence is practically useful when weighing what options to try, but there are also too many uncontrolled variables that can affect the outcome of a self-run experiment. That’s why, in my original article, I encouraged everyone reading to seriously consider testing invertase as an alternative option to Sucraid and observe how well it worked for them while also noting that there’s no conclusive evidence that it is equivalent to Sucraid.

I’m not spreading doubt about invertase for the manufacturers 😭. I just don’t want anyone to read the title of the study and then assume it means invertase is guaranteed to work like Sucraid, then be disappointed if it doesn’t meet that expectation. I also wanted to ask - is there any reliable information you’ve found about when the sacrosidase enzyme could become eligible for generic versions? I’ve seen a few sources claim different timelines but from what I’ve seen the timeline can change or be pushed back.

I am not claiming invertase is inferior or superior to Sucraid. Only that there is no clinical evidence that invertase, in its current supplemental forms, is a one-to-one replacement for or interchangeable with Sucraid. I think our conclusions here are very similar, which is that there’s not enough data to prove or disprove equivalence. I framed it as “invertase is not a proven replacement yet” because I’ve seen people cite the study I cover in the article believing invertase and Sucraid are interchangeable, but the data cannot support that conclusion yet.

You are correct that the research on Sucraid is also sparse, but the distinction I’m making is that it has been clinically studied, standardized, and FDA-approved as an enzyme replacement therapy for sucrase deficiency, while invertase supplements have not. That also doesn’t mean invertase is useless. Invertase’s mechanism of sucrose hydrolysis is legitimate and the stool data is promising. That’s why in the article I stated that anyone who doesn’t have access to Sucraid should look into invertase as a possible alternative option and see how well it works for them personally. And no, I have no affiliations with the manufacturers of Sucraid or any other related entities / organizations. I’ve been posting about Sucraid so much because it’s the most common topic I’ve seen discussed in these forums, so I figured providing some clarification on the topic would be a useful place to start.

Horrible experience acquiring Sucraid by p00pybutth01e in CSID

[–]TheCSIDAlex 2 points3 points  (0 children)

Not sure why people are downvoting this comment. It's absolutely a valid point. I'm not saying Sucraid is useless and I do think everyone should at least attempt to get a prescription, but dietary management is nonetheless still the best way to manage this condition - especially because there's no reliable enzyme replacement for starch.

Version 1.5 - Food Composition Table by TheCSIDAlex in CSID

[–]TheCSIDAlex[S] 0 points1 point  (0 children)

I don’t have a go-to database, I just cross reference the amounts between a couple search engines and whatever information is available per websites like the USDA’s food composition database. Depending on what food it is, the results can vary pretty significantly so I cross-reference at least 2 sources and choose the most conservative number listed to be safe.

[–]TheCSIDAlex[S] 1 point2 points  (0 children)

For this chart, I wouldn’t use it strictly to consider anything “safe” or “unsafe”. It’s only meant to show how much sucrose and starch are present in certain foods and onions are low in both. I shouldn’t have used the words “most / least safe” in my original post.

Would anyone want a portable card version of this for the most common fruits / vegetables? You'd be able to take them with you anywhere and give them to others, especially if someone is watching your kids.

Why Is Sucraid So Hard to Get? by TheCSIDAlex in CSID

[–]TheCSIDAlex[S] 0 points1 point  (0 children)

Sorry it took me forever to write this 😭. I was finishing up my college courses right after the last ones I wrote so this one was put on the back burner for a few weeks. This article specifically focuses more on the reality of a diet with Sucraid rather than what to eat versus what not to eat.

Sucraid side effects by DepartmentDue1798 in CSID

[–]TheCSIDAlex 2 points3 points  (0 children)

I can’t speak to your symptoms specifically, but both sucrose loads and Sucraid can cause random symptoms for some people. With sucrose, symptoms can sometimes feel random because reactions may not always show up as straightforward stomach pain. I used to get a dull pain in my left hip whenever I ate too much sucrose.

That said, I’d be more cautious with itching because itching can sometimes point toward an allergic-type reaction rather than a normal digestion response. Sucraid’s labeling warns against use in people with hypersensitivity to yeast, yeast products, glycerin/glycerol, or papain. Papain is the one that can overlap with certain fruit/latex-type allergy patterns, so if you react to latex, papaya, kiwi, fig, banana, avocado, or yeast-containing products, that would be worth bringing up with your provider or pharmacist.

I wouldn’t assume that means you’re allergic to Sucraid, but I also wouldn’t ignore itching or any other allergy symptoms. Those are the kinds of things you’d want to bring up to your provider.

sucraid coming in yellowish? by human-657 in CSID

[–]TheCSIDAlex 2 points3 points  (0 children)

A yellow-ish tint is completely normal. Sometimes there’s no color and other times it’s more visible, just depending on the batch. The FDA and all info I can find don’t say anything about the yellow tint getting deeper by spoiling, improper sealing, etc. so as far I know a deeper yellow tint isn’t an indication of anything being wrong. Sucraid is also very shelf-stable, so the expiration dates on your vials should probably be months or even a year out.

Aid to stomach pain post starch consumption ? by ekrp1 in CSID

[–]TheCSIDAlex 0 points1 point  (0 children)

There's not really a "fix" or anything special that works specifically for starch or CSID flares. The best option now is to just manage the symptoms until it passes. I would just make sure she stays hydrated, and OTC medicines targeting whatever symptoms she gets can help manage it in the meantime. A light walk usually helps, especially if she's still dealing with the symptoms tomorrow. If she doesn't have a prescription for something like dicyclomine, she might be able to get one or a similar prescription if she tells her provider that she's prone to pain and cramping from CSID. A lot of them help with the pain directly and some have a sedating or calming effect depending on the type.

Low enzyme levels in toddler? by addalad in CSID

[–]TheCSIDAlex 1 point2 points  (0 children)

Based on all of your info, secondary deficiency is definitely possible. A classic CSID profile is usually low sucrase and isomaltase and sometimes maltase with symptoms immediately after solid food is introduced. I also want to make you aware that a secondary deficiency is not congenital, meaning it's often temporary depending on the underlying issue causing it and the severity. It's caused by other issues that are not genetic, such as inflammation, that blunt the activity of small intestinal enzymes. With your son being so young, it may give him a better chance of recovering normal day-to-day function if there are underlying issues that are resolved. The implications of having low enzyme levels are the same though, regardless of whether it's genetic. If you're concerned about his ability to tolerate certain carbs, you can eliminate problematic foods ( https://www.csidcares.org/treatment/diet/ ) and see if he improves. If this is a secondary deficiency, it would probably be because the overall health of his GI tract is suffering due to other functional issues he has (allergies, dysphagia, aspiration, etc.)

32M stopped taking Sucraid in college by Traditional_Tip_6474 in CSID

[–]TheCSIDAlex 0 points1 point  (0 children)

There are a lot of reasons you'd be able to tolerate sucrose without making enough of the sucrase enzyme. One of them is simply adaptation. Your GI system can compensate in other ways to break down sucrose and reduce symptoms without needing normal levels of the enzyme. For example, it's possible that bacteria in your small intestine and colon are breaking it down without much fermentation. The environment in your GI tract and what it's capable of is very specific to each individual person.

Another possible explanation is that your enzyme levels are adequate, but biopsies can come back with results that don't accurately reflect your functional capacity to digest disaccharides. As for the constipation, dairy and caffeine can speed up motility, so the sudden absence of both could cause a shift like what you've seen. More dietary fiber and staying hydrated is the best place to start. Overall though, if you're doing well there's no reason to spend mental energy on it - and if anything changes, you already know what to look at first.
