Taking this supplement for 12 weeks in middle-aged women with low nutrient levels is linked to a rise in lymphocytes — a type of immune cell involved in long-term defense — but does not change other immune cells like neutrophils or IgM antibodies.
Claim Context
In middle-aged women aged 45–63 with suboptimal micronutrient intake, 12 weeks of daily supplementation with vitamin D3 (5000 IU), vitamin K2 (100 μg), vitamin B6 (2.5 mg), vitamin B12 (1000 μg), and magnesium (75 mg) is associated with a significant increase in lymphocyte percentage and no change in IgM or neutrophil percentage, suggesting a selective effect on adaptive immunity rather than innate immunity.
“Total WBC count showed a modest, non-significant upward trend, but the percentage of lymphocytes rose significantly. In contrast, serum IgM levels and neutrophil percentage remained stable with no significant changes”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether this supplement consistently increases lymphocyte percentage without altering neutrophils or IgM across multiple RCTs in middle-aged women.
A systematic review and meta-analysis of at least 8 RCTs comparing the same supplement regimen to placebo in middle-aged women (45–65) with low micronutrient status, measuring lymphocyte, neutrophil, and IgM percentages as primary immune outcomes.
Whether the supplement directly causes selective lymphocyte increase without affecting innate immune markers.
A double-blind RCT with 150 middle-aged women (45–65 years) with low vitamin D and B12, randomized to supplement or placebo for 12 weeks, with flow cytometry-based lymphocyte and neutrophil percentages measured at baseline and endpoint.
Whether long-term use of this supplement is associated with sustained selective lymphocyte elevation in real-world settings.
A prospective cohort study following 400 middle-aged women (45–65 years) over 2 years, tracking supplement use and measuring lymphocyte and neutrophil percentages quarterly, adjusting for infection history and stress levels.
Whether women currently taking this supplement have higher lymphocyte percentages and stable neutrophils/IgM compared to non-users at a single point in time.
A cross-sectional analysis comparing lymphocyte, neutrophil, and IgM percentages in 800 middle-aged women (45–65 years) who have taken this supplement daily for ≥12 weeks versus matched controls who have not.
Whether individual cases show selective lymphocyte increases after taking this supplement.
A case series documenting lymphocyte, neutrophil, and IgM changes in 20–30 middle-aged women who self-initiated this supplement and had pre- and post-supplementation complete blood counts available.
