Frequently Asked Questions

General FAQs

Honey and arabic gum are used in our tablet manufacturing process. Cellulose is often used to give body to the powders. Calcium stearate, derived from vegetable sources, is used as a lubricant to help products release from the tooling of the tablet and capsuling machines. No artificial flavoring is ever used.

Because of the variability in sources of natural and organic ingredients, color, texture, and odor may vary from batch to batch. However, the basic formula remains constant, and quality is ensured by repeat testing.

The calcium stearate we use is derived from palm oil, which is a saturated fat, like cocoa butter, dairy fats, etc. It is approved by the FDA to be used as a lubricant and is approved for use in food products.

Yes. The gelatin is derived from bovine and/or porcine sources. Cellulose is used to make vegetarian capsules.

Yes. All of our gelatin capsules are certified kosher or pareve/parve. Pareve/parve is a classification under Jewish dietary law meaning the product has been processed so extensively that it can be considered to have been prepared without meat, milk, or other derivatives.

Yes. Some patients open the capsules and mix the contents into a food or beverage source, such as applesauce, yogurt, or a nutritional shake.

Zypan, Betaine Hydrochloride, and Cal-Amo should never be chewed because the acids may cause potential damage to tooth enamel. Chlorophyll Complex softgels will temporarily stain the teeth and turn the tongue green.

Some Standard Process supplements are designed as chewables for those who cannot swallow capsules or tablets. After chewing, taste-bud receptors tell the brain what is entering the digestive system. Tasting is considered the first stage of digestion, when salivary secretion enzymes are activated.

Our products are processed in a facility that manufactures other products containing soy, milk, eggs, wheat, peanuts, tree nuts, fish, and shellfish. The preceding statement is printed on every product label to alert extremely sensitive patients. Please read our labels carefully for any possible ingredient allergens before recommending supplements to patients who are sensitive to certain foods. While we take precautions to avoid cross-contamination by thoroughly cleaning and sanitizing equipment and cleaning production suites, it is possible that some allergen residue may be present.

Nutritional yeast, S. cerevisiae, is not pathogenic and does not cause candida or other yeast infections.

For 90 years, Standard Process has been committed to making high quality whole food-based supplements that change lives. Please refer to the “Best By” date on all product boxes and bottles to determine how long a product maintains optimal quality and/or flavor. Standard Process only guarantees product potency through the “Best By” date.

Additionally, Standard Process no longer advises healthcare practitioners and patients to use product lot codes to verify when a product was produced. In early 2019, the company implemented a new Enterprise Resource Planning system that randomly generates lot codes for internal production traceability only. Due to varying degrees of potency, quality and/or flavor of product ingredients overtime, the “Best By” date continues to serve as the best reference for customers.

Below is an example of the different parts of our label and what they refer to.

Only Peanut Butter Standard Bars continue to be made with peanut butter. Recognizing the severity of peanut allergies, Standard Process has removed peanut bran from its products and replaced it with rice bran.

The sucrose found in our products comes from natural sources such as beets and sugar cane. Sucrose, along with starch and arabic gum, is used to coat vitamin A and vitamin D (cholecalciferol), making them into a powdered form that helps prevent oxidation of these vitamins. The amount of sucrose in the actual product is very minimal.

Nutrimere and Iodomere contain green-lipped mussel. Glucosamine Synergy contains glucosamine sulfate that is derived from crab and shrimp. While not a shellfish, calamari (the source of oil in Calamari Omega-3 Liquid) is in the same family and may trigger a reaction in those who are allergic to shellfish. Please consult the product labels for the complete ingredient listing on each product.

Some products contain soybean ingredients, such as soy powder, soy nuggets, and soy protein. Soybean lecithin, a source of choline and B vitamins, is found in other Standard Process products. It acts as an emulsifier, keeping water and fats from separating in foods. Individual sensitivities to soy protein should be discussed with your patients.

The body processes most compounds based on concentration; so the more there is, the faster your body works to process it. The key is getting the right concentration at the right time. Taking smaller amounts throughout the day allows the body to maintain a lower but more consistent amount for a longer period of time. It is more efficient for your body and more effective in sustaining the molecular mechanisms supported by the compounds in our supplements.

Consistent with our commitment to produce and sell only the highest-quality dietary supplements, each batch of marine oil is tested for potential oxidation, mercury, polychlorinated biphenyls (PCBs), and dioxin. The product is also tested for bacteria and to verify our label claims. These tests are carried out by Standard Process and third-party labs. We use this process for testing Tuna Omega-3 Oil, Tuna Omega-3 Chewable, and Calamari Omega-3 Liquid.

During manufacturing, our marine oils are processed to retain their natural triglyceride structure.

We also take great care in sourcing our marine-oil products. Tuna comes from the abundant skipjack and/or yellowfin tuna populations. Our calamari oil is certified as sustainable by a nonprofit, nongovernmental organization, Friend of the Sea®.

All products do meet the standard disintegration levels set forth by the United States Pharmacopeia (USP). Water and vinegar are not good models for how the stomach digests foods.

Yes, visit here for products organized by dietary restrictions. Patients and health care professionals should know that we follow the FDA guidelines, which state that products that contain less than 20 parts per million (ppm) of gluten can be labeled as gluten-free. All of our products that are designated as gluten-free contain less than 20 ppm and are tested every time they are manufactured to be sure that they meet this standard.

Standard Process is committed to the health-giving properties of whole food nutrition and using ingredients that have not been genetically modified. As part of this commitment, we first source ingredients from our own 623-acre certified organic farm. Certified organic farming does not allow for genetic engineering. A great majority of all raw plant ingredients used to make our products are grown on our farm. When sourcing ingredients we can’t grow on our farm, we are committed to selecting partners who offer ingredients that have not been genetically engineered. We rigorously evaluate all outside vendors and validate the raw ingredients they supply.

Standard Process products are thought to work synergistically and support multiple aspects of health. In some cases, combined products can result in very high levels of certain vitamins or minerals. Where warranted, guidance is provided for individual products on the label and in this catalog via warnings and cautions. Additional information about vitamin and mineral levels is provided through the “daily values” reported on the label. These values, set by the Food and Drug Administration, indicate how much of the recommended daily consumption of the nutrient is found in a serving. Several excellent resources detailing vitamin/mineral action and current knowledge regarding recommended levels are available online.

  • Linus Pauling Institute
  • Food and Nutrition Information Center
  • Mayo Clinic

Manufacturing Questions

Honey, arabic gum, cellulose gum, and cellulose are used as binders. Calcium stearate, derived from vegetable sources, is used as a lubricant to help the products flow into the tablet machines.

No, they are derived from vegetable sources.

The three types of yeast used in some of our products are:

Nutritional yeast

High chromium yeast

High selenium yeast

Most are made of gelatin, derived from animal sourced collagen. The others are made from vegetarian cellulose. The capsule itself is manufactured to result in a strictly kosher gelatin product.

Yes; however, some products include ingredients that may be harmful to teeth so it would be best to check with your health care professional.

Yes; it is not necessary to leave the product in the capsule if you prefer to take the product in the powder form.

The shelf life on most of our products is between 1½ and 2 years. The "Best Used By" information, located on all product boxes and on the shoulder of all product bottles, represents the date by which the product is best used by and the product code. Standard Process only guarantees product potency through the “Best Used By” date. Products are continuously tested to determine their shelf life. This testing has shown that certain products tend to have shorter shelf lives, which is reflected in the "Best Used By" date.

Do products have a longer shelf life if they are unopened?

No, the shelf life is the same.

Unlike what the pharmaceutical industry and some news media would have you believe, the supplement industry is indeed regulated and inspected by various governmental agencies. Standard Process Inc. is regulated and inspected by:

  • The Food and Drug Administration (FDA)
  • The United States Department of Agriculture (USDA)
  • Wisconsin Department of Agriculture (WI-DA)
  • Occupational Safety and Health Administration (OSHA)
  • Midwest Organic Services Association (MOSA)
  • Wisconsin Department of Natural Resources (DNR)

As a precaution, Standard Process will be adding the following warning statement to all product labels: This product is processed in a facility that manufactures other products containing soy, dairy, egg, wheat, peanut, tree nuts, fish, and shellfish. Standard Process has also added a similar warning on MediHerb products that are packaged in our facility. This warning is meant for people who may have severe allergies to these foods.

Standard Process follows good manufacturing practices to avoid cross-contamination--practices such as taking apart and cleaning all equipment between production runs. It's just one way we can make our products safer for consumers.

Standard Process is committed to the health-giving properties of whole food nutrition and using ingredients that have not been genetically modified. As part of this commitment, we first source ingredients from our own 623-acre certified organic farm. Certified organic farming does not allow for genetic engineering. More than 80 percent of all raw plant ingredients used to make our products are grown on our farm. When sourcing ingredients we can’t grow on our farm, we are committed to selecting partners who offer ingredients that have not been genetically engineered. We rigorously evaluate all outside vendors and validate the raw ingredients they supply.

Between each separate product run, any equipment that comes in contact with ingredients or finished product is disassembled and washed.

Cleaning agents are rotated monthly to avoid bacterial resistance.

Swab samples are taken from several areas of each piece of equipment.

These samples are exposed to a luminometer, which fluoresces in proportion to the amount of adenosine triphosphate (ATP) in the sample.

ATP is found in and around all biological matter and would indicate a possible bacterial presence.

If the luminometer measures ATP results beyond an acceptable level, the cleaning process is repeated and additional ATP tests are conducted.

This is done as many times as needed to obtain acceptable samples.

After the cleaned equipment passes the ATP testing protocol, the equipment is sanitized.

Only then is the equipment reassembled for use with a new batch of product.

If a clean piece of equipment is unused for more than 24 hours, it is resanitized prior to use.

In addition to the equipment itself, the surrounding production suite, including the floors, walls, and vent covers, is cleaned.
