Maintaining a strong immune system is essential for fighting off and preventing illness. Luckily there are simple ways to improve your immune system, like with getting enough vitamins and minerals. Vitamin C is an example of an essential vitamin for promoting immunity. In this post, we’re going over what vitamin C is, natural sources, popular supplements, and more!
What Is Vitamin C?
Vitamin C (ascorbic acid) is a water-soluble vitamin, which means it dissolves in water and is excreted from the body. Whereas fat-soluble vitamins are stored within the body. Because of this, you will need to replenish this daily through your diet.
Benefits:
This vitamin plays a role in fighting infections, promoting healing of wounds, and is a powerful antioxidant. Additionally, it’s also important for maintaining the health of collagen; collagen is a connective tissue that holds muscles, bones, and other tissues together. Vitamin C may also support absorption of iron and help reduce the risk of chronic diseases, like heart disease. And is essential for carnitine and neurotransmitters biosynthesis.†
Vitamin C Sources:
Not surprisingly, oranges are rich in this vitamin! But, if you’re not a fan of oranges, there are other fruits and veggies that are a great source for vitamin C.
Fruits:
- Oranges
- Kiwi
- Lemon
- Grapefruit
- Strawberries
- Tomatoes
Vegetables:
- Broccoli
- Brussels sprouts
- Cabbage
- Cauliflower
- Bell peppers
- White potatoes
And, if you struggle to meet the recommended daily allowance (RDA) through food there is also supplements. The current RDA for adults is 75mg for females and 90mg for males. However, there are times you may want to consider taking more, such as during illness or pregnancy.†
Vitamin C Deficiency:
One of the most recognized signs of this vitamin deficiency are symptoms of scurvy. Scurvy is a disease that can cause other issues such as anemia, bleeding gums, bruising and poor wound healing. Luckily, this deficiency isn’t common in developed countries. But, if you believe you may not be meeting the RDA, there are signs and symptoms of a vitamin c deficiency to look out for.†
Signs of a Deficiency:
- Scurvy†
- Fatigue†
- Malaise†
- Gum Inflammation†
- Joint Pain†
- Poor Wound Healing†
- Iron-deficiency Anemia†
Popular Products:
In this section, we’re going to introduce some of our popular products:
But these aren’t the only popular options available. You can view other products on our website.
Hi-Tech Pharmaceuticals:
Hi-Tech Pharmaceutical’s Vitamin C comes with bioflavonoids and their advanced Cyclosome Liposomal Delivery Technology, which can improve the absorption of this formula. With the addition of Citrus bioflavonoids, this product may also improve blood flow and ease swelling/inflammation.†
How To Take It:
Hi-Tech Pharmaceuticals’ recommends healthy adults taking two (2) tablets one to two times daily, preferably with food.
Customer Review By Eric: “This is great vitamin option. Normally I just go for gummies because I hate taking pills, but these aren’t bad and help avoid the unnecessary sugars. I didn’t get nausea or heartburn either!”
NOW Foods:
NOW Foods C-1000 tabs is one of their most popular version of Vitamin C. This version features both Rose Hips and Bioflavonoids, where Rose Hips are high in vitamin C. Rose Hips may be help in preventing and treating colds, flu, and vitamin C deficiencies. Because this line doesn’t contain any additional ingredient or delivery system, it may not be as bioavailable as Hi-Tech’s. Meaning, while there is 1000mg of ascorbic acid, your body won’t be able to to absorb 1000mg.†

Vitamin C FAQs:
Is Vitamin C The Same As Ascorbic Acid? |
|---|
| Yes! Though some research articles say ascorbic acid is vitamin c in its purest form, most articles use them interchangeably.† |
Can I Take It With Zinc? |
| Yes! Some studies suggest taking both these nutrients may help reducing symptoms of colds and other respiratory infections. However, more research is needed to confirm this.† |
Vitamin C For Periods? |
| It’s possible for vitamin c to elevate estrogen levels (especially when taken with these oral contraceptives) and lower progesterone levels. This may cause the uterus to contract and the lining of the uterus to break down, leading to the onset of menstruation. † However, more research is needed to confirm this.
Outside of this, studies show variations in serum antioxidant levels throughout the menstrual cycle, higher levels during ovulation and lower during the first day of menstruation. Yet studies did not find supporting evidence that supplemental vitamins could alleviate PMS symptoms.† |
Is It Good For Skin? |
| Ascorbic Acid does play an important role in maintaining skin health. But should you supplement it or apply it topically? Studies show that this vitamin in the form of a serum is proportionally effective to its concentration. But this studies also shows this concentration is only maxed out at 20% for efficacy. Meaning a serum that claims 50% concentration is no more effective than 20%. However, serum featuring a combination of tyrosine, zinc, and vitamin c may increase the bioavailability for your skin 20-times. Yet, magnesium ascorbyl-phosphate (MAP) may be the most stable and preferred ascorbyl-ester. This is because it is easily absorbed into the skin, can promote hydration, and increase collagen production.† |

- Nausea, vomiting and diarrhea
- Heartburn
- Stomach cramps or bloating
- Fatigue and sleepiness, or sometimes insomnia
- Headache
