insights Analysis
California Gold Nutrition's Immune 4 is a direct and well-received supplement designed to support the body's natural defenses and overall wellness. It combines 500mg of Vitamin C (as Ascorbic Acid) with 50mcg of Selenium (as L-Selenomethionine), two key nutrients widely recognized for their antioxidant and immune-modulating properties. This formulation targets general health and anti-aging benefits by combating oxidative stress and supporting cellular function. The product's large serving size per bottle offers good value over time, making it a convenient option for daily supplementation.
- Contains two crucial immune-supporting ingredients: Vitamin C and Selenium.

- Offers a good dose of Vitamin C (500mg) for daily support.
- Excellent value with 180 servings per bottle at a competitive price per serving.

Vitamin C 85
The product provides 500mg of Vitamin C as Ascorbic Acid, which is a standard and effective daily dose for maintaining adequate levels and supporting immune function. Ascorbic acid is a widely recognized and well-researched form of Vitamin C.
Selenium 65
It contains 50mcg of Selenium in the L-Selenomethionine form, which is highly bioavailable and well-utilized by the body. While beneficial for general maintenance and antioxidant support, the dosage is on the lower side compared to common standalone Selenium supplements, which often offer 100-200mcg for more targeted benefits.
Goals
Both Vitamin C and Selenium are fundamental for a healthy immune system, supporting various cellular functions involved in defending against pathogens. Vitamin C is a powerful antioxidant that enhances white blood cell function, while Selenium plays a role in the production of immune cells and the regulation of immune responses.
Vitamin C is vital for collagen formation, iron absorption, and overall tissue repair, contributing broadly to general well-being. Selenium supports thyroid function and acts as a crucial antioxidant, which helps protect cells from damage, underpinning overall health.
Both Vitamin C and Selenium are potent antioxidants that combat oxidative stress, a primary driver of cellular aging. By neutralizing free radicals, they help preserve cellular integrity and reduce damage to DNA, proteins, and lipids, thus supporting anti-aging processes.
