Cataplex® B2 by Standard Process - Formally Known As Cataplex G

By Dr. Candy Akers

Standard Process Cataplex B2 is a whole food supplement that used to be called Cataplex G. It provides a balanced blend of nutrients to support the body's natural healing processes. As a holistic practitioner, I recommend this supplement to my patients who are looking to improve their overall health and well being. Its also important for heart health and mental health.

Cataplex B2 contains a synergistic combination of B vitamins and other important micronutrients that work together to support optimal health. Just some of the examples of use are to promote healthy energy levels, support the nervous system, and maintain healthy skin, hair, and nails.

The following information is a summary and review based on Dr. Candy’s professional experience and recommendations. Any summary or statement has not been provided nor influenced by the manufacturer.

Cataplex B2 Side Effects: 

Little to no side effects are reported for the majority of users. A few users mentioned a stomach ache when taken on an empty stomach or with multiple supplements at the same time. I recommend starting with just one supplement at a time, to let your stomach get used to it. Additionally, this specific product is recommended to be taken with a meal.

What Happened to Cataplex G?

At the end of the year 2022, Standard Process changed the name of Cataplex G to Cataplex B2. Vitamin “G” stands for “growth factor” and in the early 1900’s it was discovered that Vitamin G was actually a combination of Vitamin B2 and B3. Over time doctors and patients have switched to calling this Vitamin B2. So the name was changed to fit the modern term in the science of vitamins.

The 'calming side of B' is great for taking before bedtime to help to relax & sleep. I use Cataplex B during the day & Cataplex G at night. Standard Process is very reliable & is easy to take just the right amount because the tablets are tiny, dissolve quickly & dosage can be adjusted to suit the individual....FOOD...nothing added, nothing removed!
