Everyone's body is different, but most people start to see a noticeable impact after 14 days of daily use and larger changes after 30 days. Consistency is key to seeing benefits since it takes some time for the MSM to build in your system!

The taste is fairly bitter but it washes it right away with water, juice, coffee, or whatever beverage you want. To make the cellular detox as pure and effective as possible, we did not use any additional flavoring or ingredients.

It takes a little bit of time to get used to it but lots of people end up craving it after taking for a few weeks!

There is a ton of misinformation out there on silicon dioxide which can make things confusing! Silicon dioxide is a natural compound found in many foods and even naturally inside the body.

There are two types, amorphous, which is what is generally found in food products and crystalline which is found in materials like quartz and sand.

Amorphous silicon dioxide, which is what we use, is well studied and classified as safe in foods.When ingested, amorphous silica is poorly absorbed by the gut and is typically excreted without significant metabolism or accumulation in the body.

Crystalline silicon dioxide, on the other hand, is what can pose some health risks but that is when it is inhaled. Furthermore, that concern primarily applies to industrial or occupational exposure (e.g. grind mortar, saw, drill concrete, or manufacture brick, concrete, stone, or ceramic) by breathing in dust, not oral ingestion.

So when people start talking about the dangers of silicon dioxide, they are most often mixing up the two and talk about the health risks of inhaling crystalline silicon dioxide, not ingesting amorphous silicon dioxide.

Silicon dioxide makes up less than 0.5% of a serving in the MSM Cellar Detox and it makes it significantly smoother and helps it dissolve in water. Without that, it is very crystalline and is difficult to dissolve which a lot of customers complained about plus it tastes way worse!

Yes you can! MSM does not contain sulfonamides, so it is generally safe for those with sulfa allergies. MSM is an organic sulfur compound, but it is not a sulfonamide. There is no known cross-reactivity between sulfonamide drugs and MSM. That being said, it is always good to start with a low dose and work up from there!

Many people with MTHFR variants take MSM without issue. However, because of potential differences in sulfur metabolism and detoxification, we always suggest people with MTHFR variants start with smaller doses and work their way up!

MSM contains sulfur which is involved in detoxification pathways in the liver. Because of this, some people with MTHFR (or other genetic variations) who have impaired detoxification or sulfur-processing pathways may find sulfur-containing supplements beneficial—or, in some cases, they may be more sensitive to them.

While MSM does contain a “methyl” component in its name (methylsulfonylmethane), its primary function in the body is not tied to the same folate- and B-vitamin–dependent methylation pathways as 5-MTHF or methylcobalamin (methylated B12).

No you don't! MSM supports detoxification by enhancing cellular function and promoting the body’s natural elimination pathways—like liver, kidneys, and lymph—not by forcefully mobilizing large amounts of toxins like some aggressive detoxes. That said, if someone is doing a more intense or targeted detox protocol, adding a binder could be helpful. But for daily cellular support and detox, most people do well with MSM on its own.

While there’s no official cure for long COVID, MSM may help support your recovery—especially if you’re dealing with fatigue, brain fog, muscle aches, or inflammation.

MSM is known for its powerful anti-inflammatory and antioxidant effects. It helps reduce oxidative stress, supports your body’s natural detox pathways, and promotes a more balanced immune response—all of which can be disrupted in long COVID.

It’s not a magic bullet, but for many people, MSM can be a valuable part of feeling like themselves again.

The vast majority of people tolerate MSM extremely well—with no side effects at all. But because MSM supports your body’s natural detox pathways, a small subset of users may experience some mild, temporary discomfort when they first start taking it.

This can include things like slight fatigue, mild headaches, or digestive changes—all signs that your body is beginning to release and process stored toxins. These effects typically fade quickly as your system adjusts. Staying hydrated and consistent with your daily dose can help ease the transition.

You can take as long as it continues to make you feel good! Some people take it for a few months to clean out their cells and reduce systemic inflammation but most people continue to take it because it makes them feel so good!

MSM is generally well-tolerated and has a very low risk of interacting with prescription medications. It’s not known to interfere with most drug pathways, and there are no widely documented interactions with common medications.

That said, because everyone’s health and medication profile is unique, we always recommend checking with your healthcare provider before starting MSM — especially if you’re taking blood thinners, diabetes medications, or undergoing treatment for a specific condition.

When in doubt, it’s best to start with a lower dose and see how your body responds.

No you don’t but you certainly can! The most important thing is to take it consistently. The MSM has a short half life in your system and it takes time to build up so make sure to take it daily to see the best results.

Start with ½ tsp (½ scoop) twice a day and work up to 1 tsp (1 scoop) twice a day or as directed by your healthcare provider.

Put the MSM directly on your tongue and swallow with water or dissolve directly into 2oz of water. For the best experience, use hot water when dissolving. Many people also like to use coffee or juice since they have a stronger flavor to wash out the taste of the MSM.

MSM contains approximately 34% organic sulfur by weight, making it one of the most efficient ways to deliver this essential mineral to your cells.

Sulfur is the 3rd most abundant mineral in your body and involved in over 150 vital bodily functions. Unfortunately, due to current farming practices and our food systems, many people are currently deficient.

Creatine has almost no flavor and blends easily into any liquid. We recommend using over 8 ounces though because anything less than that can end up being chalky.

Yes! It is incredibly important to take creatine daily because it takes time to build up in your system so you have enough to experience the full benefits.

Not necessary. The old-school approach of taking 20g/day for a week will saturate your muscles faster, but may cause bloating and stomach issues. 3-5g daily will get you there within a few weeks. Skip the loading unless you're in a hurry.

3–5 grams of creatine monohydrate daily. Is the recommended dosage. You can take more, but there's no proven benefit for most people. Studies show muscle saturation occurs at around 3-5g daily for the average person. Taking more doesn't improve results and may cause digestive discomfort. The only exception might be larger individuals (200+ lbs) who could benefit from 5-7g daily.

No. Your body produces creatine naturally, and supplementing consistently maintains optimal levels. There's no benefit to cycling off, and you'll lose the accumulated benefits if you stop.

Post-workout is slightly better for muscle building, but consistency matters more than timing. Take it when you'll remember to take it every day.
