The quality is good. The ingredients are below the product description. The quantity is about two months. Folic acid. Energy. I did not notice a flow of niacin. The package is tight. It affects the color of the urine, may God protect you. The effectiveness of the nervous system and metabolism. The taste has an unpleasant smell, frankly.

Great
Verified Purchase
Thorne is a must-have for people who need nutritional support to cope with a stressful lifestyle. The nutrients in the Anti-Stress B Complex work synergistically throughout the body to support cellular energy production, healthy red blood cell formation, normal cognitive function and an improved mood. Additional vitamin B5 (pantothenic acid), an important nutrient for adrenal, nervous and immune health, is combined with an optimal balance of eight essential B vitamins and choline.

Vitamin B Complex for Energy Metabolism
Verified Purchase
I found that the one with a higher riboflavin B2 content suited me better when exercising or studying (using brain energy). Capsules with a higher riboflavin content are yellower. I purchased both the Basic and Stress varieties and have been taking them very effectively. I am satisfied with the ingredients, quality, and efficacy.

important complex
Verified Purchase
It is important to support your nervous system with B vitamins, especially during periods of difficult physical exertion, stress, and problems. There is no doubt about the quality of this brand, pure composition, good quality, small size, folic acid in a bioavailable formula, a small influx is possible, from a larger amount of niacin, but it passes quickly. Gives energy. The effect is visible almost immediately.

Best product
Verified Purchase
I bought it because my voice is lost, my throat is dry, and I have muscle pain. I hope it helps, honestly. I feel like it gave me good energy and I don’t get tired quickly, but not too much. Maybe I need to take other supplements to improve my extreme fatigue.

I have been taking Thorne Anti-Stress B-Complex for some time now, and it has been a real revelation for my daily balance. I feel that my nerves have become more resilient - minor stresses no longer drain my energy, and the day passes calmer and more productively. My energy in the morning is more stable, there is no sharp “rise-fall”, and in general my brain seems to work more clearly. What I especially appreciate: the feeling of support and balance comes naturally

First time buying this brand
Verified Purchase
I heard this brand has good quality so I decided to try it for B vitamins because the Sports Research brand one is out of stock. The capsules have yellow/orange powder inside it and it makes my urine very yellow. There's no obvious taste/aftertaste. I supplement with this because I'm not sure if I'm deficient in the B vitamins and I am often stressed. I have taken about a week of it and have not noticed any obvious changes or side effects.
