According to Standard Process, their Cataplex B supplement is a whole-food formula designed to support the metabolic, cardiovascular, and nervous systems. Learn what does Cataplex B do for your body and how it differs from synthetic B-complex vitamins through its natural ingredient base.

Quick Summary

Cataplex B is a whole-food supplement containing B vitamins that support energy production, cardiovascular health by regulating homocysteine, and nervous system function by aiding neurotransmitter synthesis.

Key Points

Energy Metabolism: Cataplex B aids in converting macronutrients (carbs, fats, proteins) into cellular energy, boosting overall vitality. This supports energy production, especially during activity.
Cardiovascular Support: The supplement helps maintain healthy homocysteine levels already in the normal range, promoting better heart and circulation health. Cataplex B contains B vitamins and choline that assist in the metabolism of homocysteine.
Nervous System Aid: B vitamins in the formula, like B6, assist in the production of neurotransmitters that regulate mood, helping to manage stress and support mental well-being.
Whole-Food Source: Unlike many synthetic B-complex supplements, Cataplex B uses a whole-food matrix with ingredients like bovine liver and beets to deliver nutrients in a more natural, absorbable form.
Synergistic Formulation: The combination of various B vitamins and other nutrients, including B4 (adenine), works together to provide comprehensive support for multiple body systems.

The Importance of B Vitamins for Overall Health

B-complex vitamins are a family of water-soluble nutrients crucial for numerous metabolic processes. As the body doesn't store them, regular replenishment through diet or supplements is necessary. These vitamins act as coenzymes, converting food into energy. Deficiencies can lead to fatigue, nerve problems, and cardiovascular issues. Cataplex B, with its whole-food base, can provide support, especially with modern dietary challenges.

Cataplex B's Core Functions

So, what does Cataplex B do for your body specifically? This whole-food supplement from Standard Process offers a blend of B vitamins from natural sources to support several key functions.

Supports Energy Metabolism: B vitamins are vital for converting food into energy. Thiamin (B1) assists in carbohydrate breakdown, and niacin is crucial for metabolizing protein, carbs, and fats. This supports energy levels, especially during activity.
Promotes Heart and Cardiovascular Health: The supplement helps maintain healthy homocysteine levels that are already within a normal range. B vitamins like B6 and choline are important for homocysteine metabolism, and the product also contains B4, which supports heart nerve conductivity.
Aids Nervous System Function: Several B vitamins are essential for nervous system health. Vitamin B6 helps synthesize neurotransmitters like serotonin and dopamine, impacting mood and appetite. Thiamin provides energy to the nervous system, and niacin contributes to neuronal development. This can be beneficial for managing stress and supporting mental well-being.

A Closer Look at Cataplex B's Whole-Food Ingredients

A key difference of Cataplex B is its whole-food base, utilizing natural rather than synthetic ingredients. The formula includes a proprietary blend from plant and animal sources.

Key B-Complex Vitamins: Provides Thiamin (B1), Niacin (B3), and Vitamin B6.
Choline: Essential for metabolism, neurotransmission, and cell membranes.
Inositol: Supports mood and emotional balance.
Proprietary Blend: Contains whole foods like bovine liver, organic beet root, nutritional yeast, defatted wheat germ, organic carrots, and organic sweet potatoes. This combination aims to provide a rich source of B vitamins and natural cofactors that are readily utilized by the body.
