Stress B-Complex
This excellent B-Vitamin product has been specially formulated to provide an extra dose of B5 in addition to an adequate dose of all B vitamins. As a result, it is exactly tailored to the increased vitamin B5 requirements that some individuals have.
Vitamin B5 and stress
Pantothenic acid (vitamin B5) contributes to normal resilience to stress. It provides support in stressful situations.
It is also essential for cell metabolism and the synthesis of neurotransmitters. That is why it contributes to the reduction of tiredness and fatigue and to normal mental performance, and helps to release energy from proteins, carbohydrates, and fats.
Extra vitamin B2 and B3
In addition to extra vitamin B5, the formula also contains higher doses of vitamins B2 and B3. Vitamin B2 has a positive effect on the nervous system, and Vitamin B3 contributes to psychological functioning.
Best form of B-Vitamins
There are factors, such as reduced liver function, poorly functioning enzymes, digestive disorders, aging, or genetic predisposition, that interfere with the conversion of inactive vitamins in the body.
All B vitamins in Stress B-Complex are in their natural, active form. These do not need to be activated, are more effective, and are better absorbed.
Other benefits of Thorne Stress B-Complex
- B vitamins in the most optimal ratio
- 1 capsule per day is sufficient
