The Human Effect Matrix looks at human studies to tell you what supplements affect Ammonia.
Full details on all Ammonia supplements are available to Examine members.
| Grade | Level of Evidence [show legend] |
|---|---|
|
Robust research conducted with repeated double-blind clinical trials |
|
Multiple studies where at least two are double-blind and placebo controlled |
|
Single double-blind study or multiple cohort studies |
|
Uncontrolled or observational studies only |
|
Level of Evidence
?
The amount of high quality evidence. The more
evidence, the more we can trust the results.
|
Supplement |
Magnitude of effect
?
The direction and size of the supplement's impact on
each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
|
Consistency of research results
?
Scientific research does not always agree. HIGH or
VERY HIGH means that most of the scientific research agrees.

Notable
|
Very High See all 4 studies |
A decrease in ammonia has been noted, and appears to influence both hepatic encephalopathy as well as persons with no significant liver damage
|
|
|
|
 
Minor
|
Low See all 3 studies |
Differential effects on ammonia, with decreases being present when glutamine is taken as part of a daily supplement routine and measured during prolonged exercise with a possible increase with high acute doses (which fades with time)
|
|
|
|
Minor
|
- See study |
Human studies suggest time-dependent influences on ammonia (increase after exercise up until 2 hours, a reduction the next day) while animal studies suggest that overdosing BCAAs can reverse a reduction into an increase
