Standard Process is one of the oldest supplement companies in the U.S., having been founded in 1929. The brand sells products through health care practitioners as well as online, and describes their products as “high-quality, whole food-based nutritional supplements.”
But does Standard Process contain supplements with research-backed ingredients, or are these just marketing claims? Does the brand use any questionable additive ingredients? What retailer sells Standard Process for the best price? And how do real users rate and describe the effects of Standard Process supplements?
In this article we’ll answer all of these questions and more as we analyze the ingredients in two of Standard Process’ most popular supplement categories: their cleanse and their vitamins.
We’ll also explain what retailer sells Standard Process for the best price and feature real, unsponsored Standard Process customer reviews.
Standard Process Cleanse Analysis
Arguably the most popular supplement sold by Standard Process is the brand’s cleanse, called “SP Cleanse.” Its ingredients are shown above.
This supplement is composed of a proprietary (prop) blend of 21 different botanical ingredients, with a total dose of 2,680 milligrams (mg). This equals an average ingredient dose of only 128 mg, which may be underdosed for any specific health effect.
To provide an example of how low a 128 mg dose is of a raw plant powder, consider the ingredient broccoli. We know that broccoli is a nutrient-rich vegetable that’s part of a healthy diet, but 128 mg of broccoli is equivalent to less of a dose than 0.1% of one single stalk of broccoli, according to the USDA.
While we consider all of the active ingredients in this formulation to be safe, and these plant ingredients may provide some nutritional benefits, we haven’t come across any clinical evidence that healthy individuals benefit from external “detoxification” supplements.
The entire concept is relatively unscientific in our opinion, because the liver and kidneys already detoxify the body, as discussed in our Rescue Detox reviews article.
On the product page on Standard Process’ website, the brand doesn’t cite any clinical trials proving this supplement or any of its active ingredients effectively detoxify the body, so we don’t understand the purpose of this supplement and consider it a waste of money.
The good thing about this product is that it’s free of any unhealthy additive ingredients.
For consumers looking to support the body’s natural detoxification processes, we recommend considering resistant starch supplementation. A medical review published in the Advances in Nutrition journal found that resistant starch supplementation “demonstrated many health benefits” and supported gut health, which is relevant given that “the gut plays a major role in detoxifying agents from food and microbes.”
Supergut Fiber Mix is our resistant starch supplement pick, because it’s formulated with a blend of fiber powders including green banana powder resistant starch and resistant potato starch.
Interested consumers can check out Supergut Fiber Mix at this link to the product page on the brand's official website.
But how do real users rate and describe the effects of Standard Process supplements? We’ll review in the next section.

Standard Process Vitamins Analysis
Vitamins are one of the more popular categories of supplements sold by Standard Process.
Rather than selling single-ingredient vitamins, the brand primarily sells vitamin and mineral blends such as “Cataplex D;” ingredients shown below:
We don’t understand why these specific nutrients are combined in this supplement, and we would recommend that consumers speak with their doctor prior to taking any vitamin blend. It may be illogical to take supplemental vitamins without a documented deficiency in those vitamins, because overconsumption of vitamins and minerals from fortified foods can cause toxicity as documented by a 2022 recall of another vitamin-fortified consumer health brand.
Sucrose (table sugar) is included as an inactive ingredient in this supplement but the sugar content is not published. We know from medical research that consuming refined sugar in excess is associated with a host of negative health effects including increased risk of cardiovascular disease and obesity, and it seems logical to avoid added sugar in supplements.
Standard Process vitamins are also relatively expensive.
Zinc chelate sold by the brand currently costs $33.48 on Amazon and contains 180 capsules providing 10 mg zinc. The capsules contain other active ingredients but we can’t find any evidence these ingredients make them more effective than zinc alone.
This is a cost of $0.19 per 10 mg dose of zinc.
Nature Made sells 100 zinc capsules for $5.79 that contain 30 mg of zinc each.
This is a cost of $0.02 per 10 mg dose of zinc, or more than 9x cheaper than Standard Process for the equivalent zinc dose.
Here’s another example:
Magnesium sold by Standard Process currently costs $40.30 on Amazon, or $0.64 per 100 mg magnesium dose.
Future Kind sells 30 vegan magnesium capsules for $21.95 that contain 200 mg of magnesium each.
This is a cost of $0.37 per 100 mg dose of magnesium, or around 2x cheaper than Standard Process for the equivalent magnesium dose.
Overall, we do not see any reason to use the unique vitamin formulations sold by Standard Process, nor does the brand appear to have funded any clinical trials proving their vitamins are more effective than vitamins of different formats that provide an equivalent dose.
Where to Buy Standard Process for the Best Price
Standard Process supplements are not sold on the official brand’s website, because the brand retails through health practitioners.
They are sold online at various third-party retailers, including Amazon.
We would recommend that consumers intent on purchasing Standard Process supplements use Amazon, because the other third-party retailers are smaller sites that we cannot verify the legitimacy of (and have never heard of prior to publishing this review), such as “Journeys Holistic Life,” “Pine Street Clinic” and more.
The risk of counterfeit products may be higher when purchasing from unverified third-party retailers.

Real Customers Review Standard Process
Amazon is a better resource for honest customer reviews than a brand’s website in our opinion.
Standard Process’ purification kit has been reviewed over 120 times at the time of publishing this article, with an average review rating of 4.5 out of 5. To the credit of the brand, the average review rating for all of their supplements appears to be quite high.
The top positive review from a verified purchaser of the purification kit comes from a user named “Tom” who claims to have experienced weight loss:
“So I completed the 21 days and have carried through the good habits for 28. I am 16 lbs. lighter and feel great. My body processes are more efficient and I started doing some short runs, the first time in a decade.”
The top negative review from a verified purchaser comes from a user named “Chev Chelios” who claims to have experienced no benefits:
“Girlfriend and I both did this 21-day cleanse…We followed the instructions exactly: no stimulants, no dairy, no gluten, no carbs, no meat, etc…Did nothing for us. Didn't lose weight, feel better, reduce gastrointestinal issues -- nothing! Truly a waste of hundreds of dollars.”
