We have been very pleased with this product. My school-age boys take it for added mental clarity & to help calm the nervous system. It’s a good price with no negative side effects.

Great for me ... intolerant to other forms

Verified Purchase

I am intolerant to methylfolate, but I wanted to help my methylation. This I can tolerate just fine. I appreciate having this alternative.

Great for autistic children.

Verified Purchase

Excellent quality and meets all expectations. My son has been using it for a year and it has greatly improved his stereotypies and hyperactivity. He's saying many new words. I recommend it.

Great Product!!!

Verified Purchase

This supplement is truly superb. I have a daughter with ASD and a speech delay, and within just one week, I noticed improvement. Although she still cannot express her thoughts in full sentences, she is now able to say what she wants more often. She is actively trying to communicate. She speaks more frequently, even if only in short words, and can better express her needs. She is now able to answer simple questions, and her therapist has also noticed reduced echolalia and improved responsiveness. The improvement may be gradual, but it is noticeable. This product is definitely worth the money. 💖🥰🥰🤩🤩🤩

An excellent active form of folic acid. I chose this product because of the good dosage and the reputation of the Source Naturals brand. The tablets are small and easy to swallow. It's an excellent choice in terms of price and quality.

For those who are sensitive to caffeine

Verified Purchase

I heard it's good for people with autism, so my family and I, including my child who has been diagnosed with ASD and ADHD, are taking it. It seems to vary from person to person; my husband (who has a tendency to be irritable) has become a little more mellow, while I (who tend to suffer from insomnia and anxiety) have developed a tolerance to caffeine. I haven't noticed much change in my child, but folic acid is a necessary nutrient, so I'm thinking of continuing to give it to him. It's really helpful that he doesn't lose sleep due to caffeine, so it's become a regular in our household.
