About this item

Thornes 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. Thornes Stress B-Complex contributes to a healthy cortisol response to stress, 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. Thornes Stress B-Complex delivers B vitamins in their active, tissue-ready forms means your body gets the highest benefit with the least additional work; the methylated forms of B12 and folate (5-MTHF) benefit individuals with certain gene mutations; and choline promotes healthy brain and nervous system function.
