Most people think of vitamin C as the “cold and flu” vitamin. And while that’s true—it’s also just the tip of the iceberg.
At Ask Dr Olz, we use vitamin C therapeutically to support hormones, adrenal health, skin, immunity, collagen, and even detox pathways. But not all vitamin C supplements are created equal.
Let’s explore the top advantages of vitamin C, and why Ultra Potent-C® is the gold standard we recommend.
1. Boosts Your Immune System
Vitamin C strengthens immune function by:
- Enhancing white blood cell activity
- Supporting antibody production
- Shortening the duration of colds and flu
- Reducing the severity of infections
If you’re constantly sick or rundown, vitamin C could be your frontline defense.
2. Powerful Antioxidant Protection
Vitamin C is one of the body’s most important antioxidants. It protects cells from oxidative stress, which contributes to:
- Premature aging
- Chronic inflammation
- Hormonal imbalance
- Tissue damage
- Brain fog and fatigue
3. Supports Collagen & Skin Health
Vitamin C is required to make collagen, the protein that gives structure to your:
- Skin
- Joints
- Blood vessels
- Bones
- Gums
It promotes skin elasticity, reduces fine lines, and helps heal wounds—making it a top choice for glowing, youthful skin.
4. Adrenal & Stress Support
Your adrenal glands use extra vitamin C during stress. It helps:
- Regulate cortisol levels
- Improve energy
- Support mood and brain function
- Prevent burnout
If you’re always tired or wired, your body might be screaming for more vitamin C.
5. Improves Iron Absorption
If you’re dealing with low iron or anemia, vitamin C can enhance non-heme iron absorption (from plant-based or supplemental sources). It pairs especially well with iron-rich foods or iron supplements like Hemagenics®.
6. Supports Detoxification
Vitamin C helps neutralize toxins, reduce histamine, and aid in liver detoxification—especially when used alongside antioxidants like glutathione and nutrients like SulforaClear®.
Not All Vitamin C Is Equal
The problem? Most store-bought vitamin C pills are:
- Poorly absorbed
- Too acidic for sensitive stomachs
- Low potency or low bioavailability
- Lacking synergistic nutrients
That’s why we recommend Ultra Potent-C® 1000.

Ultra Potent-C by Metagenics is:
- Buffered (gentle on digestion)
- Clinically formulated for high bioavailability
