Why Is Vitamin C Important? | The Role of Vitamin C in Beauty and Health
Not feeling your best lately—skin or body-wise? It might be due to a lack of vitamin C.
This essential nutrient plays a vital role in many bodily functions and is crucial for both beauty and health.
For example, collagen—responsible for skin’s firmness and hydration—requires vitamin C to be synthesized. It also helps suppress melanin production, which causes dark spots after sun exposure, contributing to clearer, brighter skin.
Vitamin C also helps eliminate reactive oxygen species (free radicals), often referred to as “rust” in the body, and supports the immune system and stress response.
Since it’s hard to get enough from diet alone, supplementing daily is ideal.
DHC Vitamin C products introduced in this article can help resolve these common concerns.

How to Take & Possible Side Effects
Vitamin C is generally a safe nutrient, but excessive intake may cause:
- Temporary diarrhea or stomach pain (especially above 2,000mg/day)
- Stomach discomfort from acidity (especially with powders or empty stomach)
If pregnant, breastfeeding, taking medications or with health conditions, consult a healthcare provider. Be cautious with iron or antioxidant supplements.
Nutrients That Work Better When Taken with Vitamin C
Vitamin E｜The Ultimate Pair for Enhanced Antioxidant Power
Vitamin E is a fat-soluble antioxidant. When taken with vitamin C, they protect each other from oxidation and enhance their effectiveness.
It's an ideal combination for UV protection, anti-aging, and skincare.
Recommended DHC Product: DHC Natural Vitamin E 60 Days
Iron (Non-Heme)｜Improves Absorption and Prevents Anemia
Vitamin C boosts iron absorption, especially plant-based non-heme iron.
This combo is especially recommended for women or those concerned about anemia.
Recommended DHC Product: DHC Heme Iron 60 Days
Collagen｜Synergistic Effect for Radiant Skin
Vitamin C is essential for collagen production.
Rather than taking collagen alone, pairing it with vitamin C helps boost elasticity and firmness in your skin.

Frequently Asked Questions
Should I take vitamin C in the morning or at night?
Answer:
Either is fine, but if you have a sensitive stomach, it’s best taken after meals.
Time-release types are ideal in the morning, while regular types can be split between morning and night.
Since vitamin C is water-soluble, taking it in small amounts throughout the day is more efficient.
Is it okay to take it on an empty stomach?
Answer:
Because vitamin C is acidic, it may cause stomach discomfort when taken on an empty stomach—especially in powder form.
Taking it after meals is recommended.
Can I take it with other supplements or medications?
Answer:
Generally yes, but caution is advised if you’re taking iron, antibiotics, or blood thinners.
Consult your doctor or pharmacist if you're unsure.
Can I take it during pregnancy or breastfeeding?
Answer:
It's generally safe, but excessive intake should be avoided during these periods.
Stick to the recommended dosage and consult your doctor if needed.
Can children or elderly people take it?
Answer:
These supplements are designed for adults, but those of junior high school age or older may take them depending on their health and body size.
Adjust the dosage accordingly or consult a physician if concerned.
Why does my urine turn yellow?
Answer:
This is due to Vitamin B₂ (Riboflavin) and is harmless.
DHC’s Vitamin C supplements contain B₂, which can color your urine when excreted.
Can I take more than one type of Vitamin C supplement in a day?
Answer:
Be careful not to exceed the recommended total intake.
The Tolerable Upper Intake Level (UL) is about 2,000mg/day.
DHC products are formulated to meet your needs with one type, so monitor your combined dosage if using more than one.
