AWhat moves White cells
11 of 27 studied
Moves it3
Human studies found a change. The grade reflects the studies behind it, from A (strongest) to D.
ResveratrolLowersGrade B
Resveratrol lowers white cells.
Human trials · Small effect · 0 studies linked
This result is graded, but no study is linked to it yet. Treat it as unconfirmed.
See leukocyte_count entry. timmers_2011: p=0.03. Merged: wbc and leukocyte_count refer to same biomarker.
Finnish saunaRaisesGrade C
Finnish sauna raises white cells.

NACLowersGrade C
NAC lowers white cells.
Human trials · Small effect · 0 studies linked

Studied, no change8
Studies looked and found no meaningful change. That is a result, not missing data.
NAD+No changeGrade B
Studies of NAD+ found no change in white cells.
Human trials · 1 study linked
Grade corrected from A to B: single source RCT only.
CreatineNo changeGrade B
Studies of Creatine found no change in white cells.
0 studies linked
This result is graded, but no study is linked to it yet. Treat it as unconfirmed.
White blood cell count not altered; anti-inflammatory effect mediated via cytokine suppression (IL-6, TNF-α, hs-CRP), not via immune cell depletion or mobilization
ZincNo changeGrade C
Studies of Zinc found no change in white cells.
Human trials · 2 studies linked
jafari_2022 immune MA (n=1,995) shows immune cell subset improvements. amling_2025 short-term zinc supplementation enhances NK cell functionality. Total WBC count is an insensitive marker for zinc's immune modulatory effects.
- Zinc supplementation and immune factors in adults: a systematic review and meta-analysis of randomized clinical trials (2022)
- Short-term oral zinc supplementation enhances Natural Killer cell functionality and decreases circulating Innate Lymphoid Cell counts and frequencies in healthy young adults. (2025)
AshwagandhaNo changeGrade C
Studies of Ashwagandha found no change in white cells.
Human trials · 1 study linked
Ubiquinol (CoQ10)No changeGrade C
Studies of Ubiquinol (CoQ10) found no change in white cells.
Human trials · 1 study linked
Omega-3No changeGrade C
Studies of Omega-3 found no change in white cells.
Small effect · 0 studies linked
This result is graded, but no study is linked to it yet. Treat it as unconfirmed.
No consistent effect on total WBC; differential shift (reduced neutrophil:lymphocyte ratio) reported in some inflammation studies at C-grade.
IronNo changeGrade D
Studies of Iron found no change in white cells.
0 studies linked
This result is graded, but no study is linked to it yet. Treat it as unconfirmed.
Iron supplementation does not directly affect WBC count. Severe IDA may cause mild leukopenia that normalises with treatment, but this is not a primary iron effect.
MagnesiumNo changeGrade D
Studies of Magnesium found no change in white cells.
0 studies linked
This result is graded, but no study is linked to it yet. Treat it as unconfirmed.
WBC count not directly modulated by Mg supplementation. Inflammatory NF-κB effects do not translate to WBC count changes.
Not studied16
No usable human study has measured White cells with these. A gap is not a negative result: nobody has looked.
