The main active ingredients in 4Life Immune Boost are 4Life Transfer Factor, vitamin C, vitamin D, and zinc. The current official product description lists 1,000 mg of Transfer Factor and 1,000 mg of vitamin C per serving.

Because it is a flavored fizzing powder, the complete product also includes ingredients needed for taste, acidity, mixing, stability, and hydration.

Main ingredients

4Life Transfer Factor

The product uses 4Life’s proprietary immune-support ingredient category. The exact source and current formula should be confirmed from the package.

Vitamin C

Vitamin C is an essential nutrient with antioxidant and normal immune-function roles. A 1,000 mg serving is much higher than the adult Daily Value, so total intake and tolerance matter.

Vitamin D

Vitamin D supports normal immune and bone function. The exact amount should be checked on the current label.

Zinc

Zinc is an essential mineral involved in normal immune function. It can cause nausea at higher intakes, and prolonged excessive intake can interfere with copper.

Powder-format ingredients

A fizzing packet may also contain:

  • acids;
  • sweeteners;
  • flavors;
  • electrolytes;
  • anti-caking agents;
  • color ingredients.

These may matter for people monitoring sugar, sodium, artificial sweeteners, or digestive tolerance.

Duplicate nutrient risk

Do not combine the packet automatically with:

  • high-dose vitamin C;
  • zinc lozenges;
  • vitamin D supplements;
  • multivitamins;
  • other immune powders.

The responsible conclusion

Immune Boost is not only a Transfer Factor product. It is a high-nutrient powder formula.

The label should be reviewed as a complete system, especially for vitamin C, vitamin D, zinc, other supplements, and the short use directions.
