Thorne, B-Complex #12, 60 Capsules. The capsules are medium-sized and white, making them easy to swallow. After taking them, my urine turns bright yellow. The price is above average. This is my first time taking them.

I'm delighted

Verified Purchase

The purest quality and ingredients. There's no taste; I drink it with food and don't notice any. The capsule size is larger than average. The packaging lasts for two months, but that's not enough; you need to take two bottles at once. Your energy will increase, and the results will be noticeable.

Convenient for maintaining your condition when you're busy.

Verified Purchase

I take this in the morning to combat fatigue. It's easy to manage because it contains multiple B vitamins in one supplement. It gives me peace of mind even when my diet is irregular. The unique supplement smell is a bit strong, so it might bother some people.

Great

Verified Purchase

Excellent, high-quality vitamin B12. I chose Thorne's vitamin B12 because of its excellent composition and active form of methylcobalamin. The capsules are small, easy to swallow, and don't cause stomach discomfort. With regular use, I've noticed more energy, improved overall well-being, and improved stress resistance. I like that there are no unnecessary additives; the premium quality of the brand is evident. This vitamin is great for supporting the nervous system and replenishing B12 deficiency. The effect is gentle and cumulative. The package lasts a long time, and it's economical to use. I'll be ordering again 👍

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!

Excellent complex.

Verified Purchase

I purchased this product for myself because I was experiencing energy loss and fatigue. Immediately after taking it, I felt a surge of energy and increased productivity. My nervous system became more resilient. I liked the product's composition, as it contains active, bioavailable forms of vitamins, which guarantee maximum absorption. The packaging was high-quality, the capsules are easy to swallow, and odorless, which is very good. Overall, I'm happy with the product.
