Hydrogen Water and ALS: What 2024 Research Shows
# Could Hydrogen Therapy Slow ALS? New Mouse Study Offers Hope
ALS is one of the most devastating diseases known to medicine. Now, a new study suggests that hydrogen therapy may help slow its progression — at least in mice.

## What the Researchers Did
[Amyotrophic Lateral Sclerosis (ALS)](/explore-by-condition/amyotrophic-lateral-sclerosis-als-) is a disease that destroys the nerve cells that control movement. These cells are called **motor neurons**. When they die, people lose the ability to walk, talk, and eventually breathe. There is no cure.
Scientists wanted to know if molecular hydrogen (H₂) — a tiny, invisible gas — could protect these motor neurons from damage.
But there was a problem. Getting enough hydrogen into the body is hard. Hydrogen gas escapes quickly. Hydrogen water doesn't carry much of it. So the researchers built something new.
They created tiny particles called **Mg₂Si nanosheets**. Think of them as microscopic wafers — far smaller than a grain of sand. When these particles reach the stomach, they react with stomach acid and slowly release hydrogen gas. This gives the body a longer, steadier supply of H₂.
The team tested these nanosheet particles in mice that carry a gene mutation linked to ALS. This mutation involves a protein called **SOD1** (superoxide dismutase 1). Normally, SOD1 protects cells. But when it mutates, it starts causing damage instead.
The mice were given the Mg₂Si nanosheets by mouth every day. Researchers then tracked their health, movement, and survival over time.

## What They Found
The results, detailed in the [original research study](/study/mutant-superoxide-dismutase-1-catalyzed-hydrogen-therapy-for-amyotrophic-lateral-sclerosis-achieved-by-intercepting-oxidative-stress-neuroinflammation-crosstalk-1785513615619), were striking for an animal study.
### Hydrogen Therapy Extended Survival in ALS Mice
Mice treated with the hydrogen-releasing nanosheets **lived significantly longer** than untreated ALS mice. Their disease also progressed more slowly. They held onto their motor function — the ability to move and grip — for a longer period of time.
### Oxidative Stress Was Reduced
One of the biggest problems in ALS is **oxidative stress**. This is when harmful molecules called **reactive oxygen species (ROS)** — think of them as tiny sparks of damage — build up in cells and destroy them.
The mutant SOD1 protein actually makes this worse. The researchers discovered something surprising: mutant SOD1 acts like a **Fenton-like agent**. That's a chemistry term for something that speeds up the production of a very harmful molecule called **hydroxyl radical (·OH)**. These radicals tear apart healthy cells.
Here's the twist: the same mutant SOD1 protein can also help hydrogen *neutralize* those radicals. The researchers used this discovery to their advantage. By flooding the area with H₂, they turned a harmful protein into part of the solution.
### Neuroinflammation Was Blocked
The study also found that hydrogen therapy reduced **neuroinflammation** — swelling and immune activity inside the brain and spinal cord. Specifically, it blocked a pathway called the **NLRP3 inflammasome**. This is a molecular "alarm system" in the body. When it gets stuck in the "on" position, it causes ongoing inflammation that damages neurons.
By shutting down this alarm, hydrogen helped protect surviving motor neurons from further attack.

## Why This Matters
[Motor Neuron Disease](/explore-by-condition/motor-neuron-disease) has very few treatment options. The drugs that exist today only slow the disease slightly. Researchers are desperately searching for new approaches.
This study points to a two-part problem in ALS: oxidative stress and neuroinflammation don't just happen separately — they **feed each other**. One makes the other worse. The researchers call this a "crosstalk" between the two processes.
Hydrogen therapy appears to interrupt that crosstalk. It attacks both problems at once. That's a meaningful insight, even at the early mouse-study stage.

## The Bigger Picture
This study fits into a growing body of [hydrogen brain research](/blog/category/brain) showing that H₂ may protect the nervous system in multiple ways. Scientists have studied hydrogen's effects on [Neurodegeneration](/explore-by-condition/neurodegeneration), Parkinson's disease, traumatic brain injury, and more.
What makes this study stand out is the delivery method. Most hydrogen research uses hydrogen water or inhaled gas. This team engineered a slow-release nanoparticle that stays active in the gut for hours. That sustained release may be key to getting enough H₂ to where it's needed most — deep inside the brain and spinal cord.
It's also notable that the researchers found a new role for mutant SOD1 itself. Instead of just seeing it as the villain, they found a way to use its chemistry to help hydrogen work *better*. That kind of creative thinking could open new doors in ALS research.
That said, **this is a mouse study**. Results in animals do not always carry over to humans. Human clinical trials would be needed to know if this approach is safe and effective for people with ALS.

## Key Takeaways
- 🔬 **Animal study only:** These findings come from ALS mice, not humans. More research is needed before any conclusions can be drawn for people.
- 💊 **New delivery method:** Mg₂Si nanosheets release hydrogen slowly in the stomach, giving the body a longer, steadier dose of H₂.
- 🧠 **Dual protection:** Hydrogen appeared to reduce both oxidative stress and neuroinflammation — two processes that drive ALS progression.
- ⏱️ **Survival extended:** Treated mice lived longer and maintained movement for more time than untreated ALS mice.
