Vitamin C provides significant stress relief by replenishing levels rapidly depleted by your adrenal glands during stress hormone production. When you're under chronic stress, your body burns through vitamin C at an accelerated rate—the adrenal glands contain the highest concentration of vitamin C in your body and use it to manufacture cortisol and other stress hormones. According to the American Journal of Clinical Nutrition, chronic stress can deplete vitamin C levels by up to 50% within weeks. Most people notice they get sick more often during stressful periods because their depleted vitamin C leaves their immune system compromised. The key is choosing a vitamin C supplement that actually gets absorbed rather than the single-form ascorbic acid tablets that often pass straight through your system unused.

Why Experiencing Chronic Stress Affects Your Immunity
Your adrenal glands are vitamin C powerhouses, storing more vitamin C per gram than any other organ in your body. During stress, these glands rapidly convert vitamin C into cortisol and adrenaline to help you cope with whatever challenge you're facing. This is perfectly normal for short-term stress, but chronic stress creates a constant drain on your vitamin C stores. According to the Journal of Nutritional Science, people experiencing chronic workplace stress show vitamin C blood levels 23% lower than unstressed individuals. When your vitamin C reserves run low, your immune system suffers because vitamin C is essential for white blood cell function, antibody production, and tissue repair. This explains why you might notice you catch every cold going around during particularly stressful periods—your body is prioritising stress hormone production over immune defence, leaving you vulnerable to infections and slower to recover from illness.
What Actually Works for Stress and Immunity Support
1. Prioritise sleep consistency over sleep duration—your adrenal glands recover most effectively with regular sleep-wake cycles, even if you can only manage 6-7 hours nightly.
2. Include magnesium-rich foods like dark leafy greens and nuts, which support healthy cortisol rhythms and reduce vitamin C depletion during stress responses.
3. Practice brief stress-relief techniques throughout your day—even 2-3 minutes of deep breathing can interrupt the cortisol cascade that depletes your vitamin C stores.
4. Choose a triple-form vitamin C supplement that actually gets absorbed. S&J Ultimate C combines ascorbic acid for potency, sodium ascorbate for quick absorption, and calcium ascorbate for stomach comfort—giving you three absorption pathways instead of hoping a single form works for your system.
5. Look for enhanced absorption ingredients like the citrus bioflavonoids and rosehip extract in Ultimate C, which extend vitamin C activity in your body and provide additional adaptogenic compounds that support adrenal function during chronic stress.
Stress and Vitamin C FAQ
Does vitamin C help with stress?
Yes, vitamin C directly supports stress relief by replenishing stores depleted during stress hormone production. Your adrenal glands use vitamin C to manufacture cortisol and adrenaline, so maintaining adequate levels helps your body cope with stress more effectively while protecting immune function.
How does stress deplete vitamin C?
Stress depletes vitamin C because your adrenal glands rapidly convert it into cortisol and other stress hormones during your body's fight-or-flight response. The adrenal glands store the highest concentration of vitamin C in your body specifically for this stress response mechanism.
What supplements help with chronic stress?
Vitamin C, magnesium, and adaptogenic herbs like rosehip extract help with chronic stress. Vitamin C replenishes what's used for stress hormone production, magnesium supports healthy cortisol rhythms, and adaptogens help your adrenal glands function more efficiently during ongoing stress.
