Thorne’s Stress B-Complex is an essential choice for individuals seeking nutritional support for an overstressed lifestyle. The nutrients in Stress B-Complex work synergistically throughout the body to promote cellular energy production, healthy red blood cell formation, cognitive function, and mood. The extra vitamin B5 (pantothenic acid), an important nutrient for healthy adrenal, nervous system, and immune function, complements the optimal balance of eight essential B vitamins plus choline.

Benefits of Thorne’s Stress B-Complex:

  • A healthy cortisol response to stress is supported by 250 mg of pantothenic acid (vitamin B5) per serving 
  • Carbohydrate, protein, and fat metabolism is promoted by the enhanced production of coenzyme A with the addition of vitamin B5
  • Enhanced cellular energy production helps fight stress-related fatigue
  • Normal neurotransmitter production supports a balanced mood

Food supplements should not be used as a substitute for a varied diet. Do not exceed the stated dosage. Store in a cool, dry place, protected from light and heat. Keep out of sight and reach of children.


5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.
