Human Effect Matrix
The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect natural killer cell content.
| 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.
|
Notes |
|---|---|---|---|---|
|
|
- | High See all 3 studies |
Although one increase in NK cell content has been noted after exercise, the two studies using similar doses at rest have failed to find a significant influence on NK cell content
|
|
|
|
Minor
|
- See study |
An increase has been noted, but there is insufficient evidence to assess the magnitude of increase or the reliability
|
|
|
|
Minor
|
Very High See 2 studies |
There is an increase in NK cell levels seen in both healthy controls as well as cancer patients, and this is thought to be due in part to both immunostimulatory and anti-immunosuppressive effects.
