Exellent product
Verified purchase
A basic B-vitamin complex is a convenient way to support energy, the nervous system, and overall metabolism. It usually includes all the key B-vitamins that work better together than individually. The capsules are easy to absorb and great for daily use, especially for people dealing with stress or irregular eating habits. A solid choice for maintaining essential B-vitamin levels.

The nice choice of vitamin B complex
Verified purchase
I bought it because it was prescribed by my doctor. I’m satisfied with the product’s quality. I like the ingredients because, as far as I know, these types of vitamin B can be taken together. I also liked the size of the package - it was enough for a month and a half. The taste was nice

I’ve been taking Thorne Basic B‑Complex for a while now and it’s become my go-to B vitamin. The capsule is easy to swallow, and the quality stands out—it delivers a well-balanced blend of all eight B vitamins plus choline, all in active forms for better absorption

My go-to General B Vitamins
Verified purchase
Thorne is top notch quality and testing. Their packaging and dosage is always correct. This is no different. When I need specific B-Vitamin supplementation, this is my go-to product. I feel great while taking, it's a single capsule and very effective. The dosage amounts are common for B-Vitamin complexes and I trust Thorne to deliver a high quality, tested product that delivers on its claims. If you need B-Vitamins, try this.

Little bit expensive!
Verified purchase
Thorne makes great supplements, and this B Complex is no exception—clean ingredients, well-absorbed forms, and gentle on the stomach. Quality is great. That said, it’s on the expensive side compared to similar options. If budget’s not a big deal, it’s a solid choice for daily energy and stress support. There was no flushing as some people say.

Clean, effective B complex with noticeable impact on energy and mood.
Verified purchase
I’ve tried several B-complex supplements and this one stands out. The forms are well absorbed (you can feel the difference), and it gives a steady boost in energy without jitters. I also noticed better focus and less mental fatigue during the day. No stomach issues when taken with food. Quality feels high, consistent with Thorne’s reputation. Only note: it can be slightly stimulating, so best taken in the morning. Overall, a solid and reliable B complex. Would repurchase.
