Catalyn is a whole food multivitamin for general well-being specially formulated to promote healthy cell function, bridge nutritional gaps in the diet, and improve overall health.

The formula is rich in vitamins (Vitamin D, Vitamin C, Vitamin A, Thiamine, Riboflavin, and Vitamin B6), minerals, enzymes, and trace minerals in

combination with their naturally occurring synergistic cofactors.

According to Standard Process, the extracts from bovine and ovine tissues provide nutrients and support to the corresponding tissues in humans. In contrast, vitamins, minerals, and nutrients from plants and animal tissues work synergistically for maximum effect.

Catalyn has amassed an extraordinary number of stellar reviews on Amazon, and it’s one of the best Standard Process selling supplements.


Catalyn, launched in 1929, is advertised as an exceptional whole food multivitamin supplement consisting of various phytonutrients, vitamins, and minerals, from approximately 15 different whole food sources. 

The product is the first product developed by Dr. Royal Lee. Rather than using the common megadose approach plus incomplete isolated nutrients, he formulated Catalyn with several whole food ingredients completed with complex nutrients. 

Furthermore, Catalyn includes specific glandular tissue to complement the whole food ingredients to stimulate tissue and cell repair. 

As a result, the complex of whole food ingredients and other minerals and vitamins that make up Catalyn broadly support both the human body’s biological and physiological processes.

Read our full Standard Process Catalyn review below for an in-depth analysis of this dietary supplement’s key features.

Who makes it?

Catalyn is produced and sold by Standard Process, a Wisconsin-based family-owned company dedicated to offering nutrient-dense and high-quality therapeutic supplements for three generations.

The company is widely known for using a holistic approach to how they farm, manufacture, and preserve the quality of their supplements. Standard Process is going to great lengths to guarantee all its ingredients are sourced from a healthy ecosystem. 

A healthy ecosystem is created by using organic farming techniques, such as crop rotation, fertilizing the soil with nutrient-rich cover crops and byproducts from the manufacturing process, practicing strict weed-control standards, and continually monitoring plants’ health.

Furthermore, all Standard Process supplements go through stringent testing. Degreed microbiologists and chemists in their on-site laboratories continuously carry bacterial and analytical tests on raw materials, product batches, and finished products.

Some of Standard Process’s best selling products include:

Are the ingredients effective?

This next part of our Standard Process Catalyn review will analyze some core active ingredients in the formula, starting with the vitamins. 

Vitamin A (360 mcg)

Even in small doses, vitamin A (also known as retinoic acid or retinol) is a nutrient essential for your health, supporting the immune system, cell growth, fertility, and fetal development.

However, perhaps one of the best-known functions of vitamin A is its role in vision and eye health. Sufficient dietary intake of vitamin A benefits vision and protects against some eye diseases, such as age-related macular degeneration (AMD).

According to clinical data, higher blood levels of beta-cryptoxanthin, alpha-carotene, and beta-carotene may reduce your risk of age-related macular degeneration by up to 25%.

Vitamin A also has antioxidant properties. Antioxidants are substances that defend cells against the effects of free radicals – molecules created when your body is exposed to radiation and smoke or breaks down food. 

Free radicals generate oxidative stress, which has been connected to many chronic illnesses, like heart disease, diabetes, cognitive decline, and cancer.

Vitamin C (4 mg)

Vitamin C (ascorbic acid) is an important vitamin that keeps the body functioning. Found in dietary supplements and many foods, it aids in multiple biological functions, including wounds healing, collagen synthesis, and the maintenance and repair of bones, cartilage, and teeth.

But perhaps vitamin C’s best-known benefit is the positive effect it has on the immune system. 

In a study published in Nutrients in 2017, vitamin C was found to strengthen the immune system by shielding against oxidative stress, minimizing the potential for tissue damage, and aiding in microbial killing. A deficiency in vitamin C has been correlated to an increased rate of viral infections. 

Vitamin D (7.8 mcg)

Despite its name, vitamin D is not a vitamin, but a prohormone (a hormone precursor).

Vitamins are nutrients that the body can’t make independently, so we must obtain them through diet. However, the body can produce vitamin D as a response to sun exposure.

Vitamin D has multiple roles in the body. It assists in:

  • Supporting brain, immune, and nervous system health
  • Promoting healthy teeth and bones
  • Supporting cardiovascular health and lung function 
  • Regulating insulin levels and supporting diabetes management
  • Influencing the expression of genes involved in cancer development

Thiamine (0.2 mg)

Thiamine (vitamin B1) helps prevent complications in the nervous system, muscles, brain, intestines, stomach, and heart. It is also involved in the flow of electrolytes into and out of nerve cells and muscle.

Other conditions in which vitamin B1 supplements may help include:

  • Canker sores
  • AIDS
  • Glaucoma and other vision problems
  • Cataracts
  • Cervical cancer
  • Cerebellar syndrome, a type of brain damage
  • Stress
  • Diabetic pain
  • Kidney disease in patients with type 2 diabetes
  • Heart disease
  • A weakened immune system
  • Motion sickness

However, not all of these potential benefits have been definitively confirmed by clinical data.

In the United States, the recommended daily allowance (RDA) of thiamine is 1.4 mg for pregnant or breastfeeding mothers of any age, 1.2 mg for males, and 1.1 mg for females over 18 years.

Riboflavin (0.2 mg)

Riboflavin (vitamin B2) is an important nutrient needed for growth and overall good health. It allows oxygen to be used by the body, and it helps the body break down fats, proteins, and carbohydrates to produce energy.

Riboflavin is also essential for forming new antibodies and red blood cells in humans, which increases oxygenation and circulation to various organs of the body.

Furthermore, vitamin B2 is required for ensuring proper growth and development of the reproductive organs, and the growth of body tissues such as the connective tissue, skin, mucous membranes, eyes, immune system, and nervous system.

Vitamin B6 (1 mg)

Vitamin B6 is a vitamin that benefits metabolism and the central nervous system. Its roles include turning food into energy and helping create neurotransmitters, such as dopamine and serotonin. 

Vitamin B6 helps regulate energy use in the brain. It also plays a vital role in creating new neurotransmitters, essential chemical messengers in the brain.

In fact, multiple clinical studies indicate that vitamin B6 deficiency may be linked with dementia and cognitive decline.

According to the Office of Dietary Supplements, available research data suggests that older adults with higher blood levels of vitamin B6 have better memory.

Because of these properties, vitamin B6 is one of the most commonly used vitamins in dietary supplements for cognitive health, stress, anxiety, ADD/ADHD, calm, and focus.

Proprietary blend (766 mg)

The most important part of the Catalyn formulation is the 766 mg proprietary blend consisting of crucial ingredients such as bovine adrenal extract, organic shiitake mushroom, organic reishi mushroom, organic dried alfalfa, magnesium citrate, and sunflower lecithin.

Many people perceive shiitake mushrooms as superfoods, the reason why they have gained so much attention from the dietary supplements industry. 

Shiitake mushrooms (Lentinula edodes) have been a known herbal remedy in alternative medicine for centuries. Some of their claimed benefits include:

  • Support the immune system
  • Improve heart health
  • Decrease the risk of prostate cancer
  • Help prevent gingivitis

Reishi mushrooms are acknowledged for their purported effects in improving the efficacy of specific cancer treatments and promoting the immune system. However, more research data and human trials are needed to assess all the potential benefits of reishi mushrooms thoroughly. 

For example, limited evidence from in vitro and animal studies showed that reishi mushrooms might support the immune system. Still, high-quality studies in humans are necessary before researchers draw any conclusions.

Alfalfa (Medicago sativa) is a perennial plant belonging to the Fabaceae family that has long been used in traditional medicine to treat various health conditions. 

Alfalfa has been shown to help lower cholesterol, and may also have benefits for blood sugar control and relieving symptoms of menopause.

People also take it for its high antioxidants content, vitamin K, vitamin C, folate, copper, and magnesium. Alfalfa is also extremely low in calories.

Recommendations, adverse effects, and warnings

Catalyn (as all Standard Process supplements) is advertised as safe to use. All ingredients used in this formulation have been carefully selected to work together synergistically and be safe and well-tolerated by all users.

Some individuals may still need to avoid alfalfa, including people taking blood-thinning medications, pregnant women, or individuals with an autoimmune disorder.

Another good example is the reishi mushroom. While likely safe in most users, reishi mushrooms can cause dizziness, nausea, itching, dry mouth, rashes, and stomach upset when taken daily for up to three months.

As always, we recommend consulting the product packaging label for the most accurate product information.


As a dietary supplement, take three (3) tablets daily with food. Following their healthcare provider’s advice, some users take one tablet per 50 pounds body weight instead of the three daily tablets suggested by the manufacturer.
