## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth it! Helps a ton!
*by  on Reviewed in the United States June 12, 2026*

We have been using these for years. They help quite a bit. They help me and my daughter focus. No side effects only positive results. Well worth the price.

### ⭐⭐⭐⭐⭐ Great product, but Amazon's price is cray-cray
*by  on Reviewed in the United States February 28, 2023*

I bought Focus DL regularly for years on Amazon; unfortunately, Amazon jumped the shark a few years ago and now their price is 55% higher than competing supplement sources. Otherwise the product works wonderfully for me in every way. I've been using Focus DL for over 12 years, thanks to neurotransmitter testing by my naturopathic doctor (ND). This was recommended as part of a pharmaceutical and supplement plan, which has greatly improved my executive functioning with zero side effects. My ND especially liked Neuroscience for their pharma-grade production facility, which she toured and said is run head-and-shoulders above many other supplement brands. I wish Amazon hadn't jacked up its prices, charging through the nose for a supplement that goes for $24.50 elsewhere.

### ⭐⭐⭐⭐⭐ Helps!!!
*by  on Reviewed in the United States December 18, 2025*

This has honestly helped me. I have gone from what seemed like a chaotic state to being prepare and able to complete a task without getting way off task. It took a couple of weeks taking it regularly before I noticed a real difference but it has been well worth it!
