Scientists reviewed 26 studies involving over 1,500 children with fatty liver disease to see which medications work best. They found that vitamin D was the top performer, helping reduce liver inflammation and improving cholesterol levels. Vitamin E also showed benefits by helping more kids recover from liver inflammation. This research is important because fatty liver disease is becoming more common in children as childhood obesity rises, and doctors need better treatment options.

The Quick Take

  • What they studied: How well different medications work to treat fatty liver disease in children and teens
  • Who participated: 1,503 children and teens (ages 7-14) from 26 different studies who had fatty liver disease
  • Key finding: Vitamin D ranked as the best overall treatment, reducing liver inflammation scores and improving cholesterol levels
  • What it means for you: If your child has fatty liver disease, vitamin D supplements may help, but always consult with your doctor before starting any treatment

The Research Details

This was a network meta-analysis, which means researchers gathered data from 26 separate studies and combined the results to get a bigger picture. They only included high-quality randomized controlled trials, where some kids got real medicine and others got fake pills, and neither the families nor doctors knew which was which until the end. The children’s fatty liver disease was diagnosed using medical scans like ultrasounds or MRI machines, or sometimes with liver biopsies.

By combining results from many studies, researchers can spot patterns that might not show up in smaller individual studies. This gives doctors more confidence in the results and helps them make better treatment decisions.

The study only included randomized controlled trials, which are considered the gold standard for medical research. However, the individual studies varied in size and length, and some treatments were only tested in a few studies, which limits how confident we can be in some results.

What the Results Show

Vitamin D came out as the clear winner across multiple measures. It significantly reduced the NAFLD Activity Score, which is like a report card for how inflamed and damaged the liver is. Kids taking vitamin D also saw improvements in their cholesterol levels - their ‘bad’ LDL cholesterol and total cholesterol went down, while their ‘good’ HDL cholesterol went up. When vitamin D was combined with DHA (a type of omega-3 fat), it was especially good at lowering triglycerides, another type of blood fat. Vitamin E showed different strengths - it was the best at helping kids achieve complete resolution of liver inflammation, meaning their liver inflammation went away entirely.

A medication called Cysteamine Bitartrate Delayed Release (CBDR) was most effective at reducing liver enzyme levels (ALT and AST), which are markers of liver damage. It also showed the strongest effects on reducing liver scarring scores. However, this medication was only tested in a few studies, so we need more research to be sure of these benefits.

This analysis confirms what some previous studies suggested about vitamin D and vitamin E being helpful for fatty liver disease. However, it’s the first comprehensive comparison of multiple treatments specifically in children, giving doctors better guidance than they’ve had before.

The studies varied quite a bit in how long they lasted, what doses were used, and how they measured success. Some promising treatments were only tested in one or two studies, making it hard to be completely confident in those results. Also, most studies didn’t combine medication with lifestyle changes like diet and exercise, which are usually recommended together.

The Bottom Line

Based on this research, vitamin D appears to be the most consistently beneficial treatment for children with fatty liver disease, with moderate confidence in the results. Vitamin E may also be helpful, particularly for reducing liver inflammation. However, these should always be used under medical supervision as part of a comprehensive treatment plan.

Parents of children diagnosed with fatty liver disease should discuss these findings with their child’s doctor. These results may not apply to children with other liver diseases or those taking certain medications.

The studies in this analysis typically lasted 3-12 months, so families should expect to wait at least several months to see meaningful improvements in liver health markers.

Want to Apply This Research?

  • Track daily vitamin D supplement intake and monthly liver enzyme levels (ALT/AST) if prescribed by your doctor
  • Work with your healthcare provider to establish a consistent vitamin D supplementation routine alongside dietary improvements
  • Log supplement adherence daily and schedule regular blood tests every 3-6 months to monitor liver function improvements
