Great quality and noticeable results Very happy with this product! The quality is excellent and the ingredients feel clean and natural. After a few weeks, I noticed better energy and overall well-being. Easy dosage, good value for money, and no side effects so far. The package was secure and delivery was fast. Definitely recommend this supplement if you’re looking for something effective and reliable.
Thorne is a brand we trust for quality. I bought this B-Complex for my husband to help support his nervous system and energy levels during a very busy time at work. It contains the active, methylated forms of B12 and folate, which are much easier for the body to use. We’ve noticed he has more sustained mental energy throughout the day. It’s definitely a premium supplement that delivers results.
Thank you for an outstanding product! I only trust the quality when I order thru IHerb. It's scary to order elsewhere since there are so many fake products online. This offered remarkable benefits. I also appreciate the secure and reliable packaging. Thanks iHerb!
Thorne B-Complex is a high-quality supplement that delivers excellent results. The formulation is comprehensive with all essential B vitamins including B12, niacin, and folate. I've noticed increased energy levels and improved mental clarity since taking this supplement. The capsule form is easy to swallow and well-tolerated. No niacin flush experienced, which is a plus. Thorne is a trusted brand and this product lives up to their reputation for quality and efficacy. Highly recommended for anyone needing a reliable B-complex supplement.
Quality: High-quality B-complex formula with B12 for energy and nerve support. Size: Standard capsules. Dosage: Once daily. Benefit: Supports brain function, nerve health, and energy production. Package: Secure Thorne packaging with easy-open bottle. Taste: No taste or smell. Other Aspects: I used to get B12 shots from my doctor, but due to new medication changes, I no longer receive them. This supplement helps serve as an alternative. I bought it during a sale and want to continue using it longer to see full effects. It's also suppose to support energy metabolism and endurance so I'm looking forward to that boost~
I'm taking this B12 with other b vitamins in it. I'm a vegetarian so took this version. It's good to see they've made products for customers preference. One can also buy the only b12 too. Thorne products are really good tbh. I can see improvement in my energy levels my tongue also healed which was prone to canker sore. Let's see how long it will help me
Just started this in addition to my multivitamin as I feel life is adding more stress these days. We burn through B vitamins the more stress we have. I feel like I've seen an improvement in my stress levels as well as my sleep quality. Love the Thorne brand.

I’ve tried different B-complex supplements before, but this one from Thorne really stands out. The formula feels clean, gentle on the stomach, and gives a noticeable boost of natural energy without any crash or jitters. After a few weeks of use, I noticed more stable mood, better focus, and less fatigue during the day. I also like that it contains methylated forms of B vitamins, which makes them easier to absorb and more effective. The capsules are small, easy to take, and there’s no strange aftertaste. Overall, this is a high-quality B-complex that truly supports energy, nervous system, and overall well-being.
