Ginger shots and immunity: how to boost your natural defenses in winter

Why your immune system needs ginger in winter

Every winter, 5 to 20% of the population contracts the flu (WHO, 2023). Respiratory infections cost 25 billion euros per year in Europe. Instead of waiting until you get sick, science shows that a preventative approach using ginger's bioactive compounds can significantly reduce the frequency and duration of infections.

Ginger: a natural immunomodulator

Gingerol (main active compound of fresh ginger) and shogaol (dehydrated form) stimulate several immune pathways simultaneously:

• Macrophage activation — Sentinel cells of the immune system. Gingerol increases their phagocytic activity by 35% (Tripathi et al., Journal of Ethnopharmacology, 2008)
• Stimulation of NK cells — “Natural killers” which eliminate cells infected by viruses. 6-shogaol increases their cytotoxicity (Park et al., International Immunopharmacology, 2013)
• Modulation of TNF-α — Reduces excessive inflammation (cytokine storm) while maintaining an effective immune response (Grzanna et al., Journal of Medicinal Food, 2005)
• Direct antiviral effect — Fresh ginger (not dry) inhibits respiratory syncytial virus (RSV) by blocking viral attachment (Chang et al., Journal of Ethnopharmacology, 2013)

Turmeric and black pepper: the synergistic trio

Curcumin (turmeric) is a powerful anti-inflammatory, but its bioavailability is naturally low (< 1%). Piperine from black pepper increases its absorption by 2000% (Shoba et al., Planta Medica, 1998). This ginger-turmeric-black pepper trio creates an immunomodulatory effect that each ingredient alone cannot achieve.

Comparison: market shots vs. INTI

Criterion	Classic shots	INTI
Sugar per 100 ml	15-34g	1.19g
Impact on immunity of sugar	Inhibits neutrophils for 5 hours (Sanchez et al., 1973)	Negligible effect
Ginger	Often in powder/flavor	Fresh organic ginger
Turmeric + black pepper	Rarely combined	Synergistic trio
Certification	Varies	Certified organic

The sugar paradox : Linus Pauling Institute showed that 100 g of sugar reduces neutrophil activity by 40% for 5 hours. An “immunity” shot with 34g of sugar literally sabotages the immune function it claims to strengthen.

FAQs

Does ginger replace the flu vaccine?
No. Ginger is a supplement, not a substitute for vaccination. It strengthens general defenses but does not target a specific virus like a vaccine does.

How much ginger per day for immunity?
Studies show effects from 1 to 2 g of fresh ginger per day. An INTI shot contains the equivalent of this dose in organic concentrate.

Does sugar really weaken the immune system?
Yes. Research by Sanchez et al. (1973) shows that 100 g of sugar reduces the phagocytic activity of neutrophils by 40% for 5 hours. More recent studies confirm that high glucose inhibits the innate immune response.
