You’ll want to aim for 75-90 mg of vitamin C daily for basic immune function, but increasing to 1,000-2,000 mg during stress or illness can greatly boost your white blood cell production. Focus on bioavailable sources like red bell peppers (190 mg per cup), strawberries, and broccoli rather than relying solely on citrus fruits. When whole foods fall short, consider liposomal vitamin C supplements taken with meals for superior absorption and maximum immune protection throughout your day.
Optimal Daily Vitamin C Dosage for Maximum Immune Protection
While most adults know they need Vitamin C for basic health, you’ll want to understand the specific dosages that provide peak immune protection.
The recommended daily intake starts at 75 mg for women and 90 mg for men, but ideal immune system support requires higher amounts. You can safely increase your daily intake up to 2,000 mg during stress or illness periods.
During times of stress or illness, boosting your vitamin C intake to 2,000 mg daily provides superior immune protection beyond basic requirements.
High doses enhance white blood cells production, strengthening your body’s infection-fighting capabilities. Focus on bioavailable sources through fresh fruits and vegetables, consuming them raw when possible.
Consider supplements like liposomal Vitamin C for enhanced absorption, especially during cold seasons when your immune system needs extra support.

Smart Supplementation Strategies When Food Sources Fall Short
Although natural food sources provide the ideal foundation for vitamin C intake, your busy lifestyle or dietary restrictions might prevent you from consistently meeting your daily requirements through whole foods alone.
When food sources fall short, smart supplementation becomes essential. The recommended daily intake varies—75 mg for women and 90 mg for men—but you’ll often need more during stress or illness.
Take vitamin C supplements with meals to enhance absorption and minimize gastrointestinal discomfort. Liposomal vitamin C offers superior bioavailability for optimal immune system support.
During challenging periods, you can safely increase daily supplementation to 1,000 mg or more, but never exceed the upper limit of 2,000 mg to avoid adverse effects like diarrhea.
