California Gold Nutrition Vitamin D3 delivers a high-potency dose of the "sunshine vitamin" that many of us lack, especially in winter months or indoor lifestyles. This essential nutrient doesn't just support bones — it's crucial for immune function, mood regulation, and yes, even gut health through its role in maintaining intestinal barrier integrity.

Vitamin D deficiency affects up to 42% of adults and can impact everything from immune response to gut barrier function. Research shows vitamin D plays a critical role in maintaining intestinal integrity, modulating inflammation, and supporting the growth of beneficial bacteria. For those healing their gut through fermented foods, adequate D3 levels ensure your body can properly utilize the nutrients and probiotics you're consuming. At 5,000 IU, this provides a therapeutic dose that can correct deficiencies within 2-3 months.

☀️ The foundational supplement that amplifies every other health intervention you make.
