Vitamin C or ascorbic acid helps boost your immunity.

Vitamin C can increase antioxidants in your body[1],[2]. More antioxidants are an excellent defense against inflammation. Chronic inflammation can lead to cardiovascular disease, type 2 diabetes, arthritis, chronic kidney disease, cancer, and other autoimmune disorders[3]. Inflammation-related conditions are responsible for more than half of all the deaths in the world.  

Vitamin C promotes healthy skin, bones, teeth, and cartilage by enhancing collagen formation[4],[5]. It helps in wound healing[6] and can reduce fatigue[7].

Vitamin C also boosts iron absorption[8]. Iron is needed to carry oxygen in our bodies. Because plant-based iron is not easily absorbed in our bodies, getting enough Vitamin C is significant for a vegan or vegetarian diet.


How Much Vitamin C Do You Need?

According to the NHS, adults aged 19 to 64 need 40 mg of vitamin C a day[9]. However, many people prefer higher amounts in their food or as supplements. Any excess is flushed out in our urine. More than 2,000 mg a day is not recommended as it may lead to digestive issues.


Best Sources of Vitamin C

Vitamin C is water-soluble, and our bodies cannot store it. So, you need the right amount every day to reap its benefits.

Many foods are rich in Vitamin C, including rosehip, orange, papaya, strawberries, chili peppers, red and green peppers, broccoli and cauliflower, pineapple, and mango.

Since Vitamin C is heat-sensitive, you must eat Vitamin C-rich foods raw or cooked lightly[10]. Try a Vitamin C Superfruit Salad or a Broccoli Pasta Salad with Red Pepper Pesto. Canned food is not a good source of Vitamin C due to the high heat involved. Dried fruits do not work either since the drying eliminates the Vitamin C[11].

Some may find it tough to eat fresh fruits and vegetables at every meal due to a lack of time, resources, or availability. You may consider all-natural Vitamin C supplements to help you meet your Vitamin C needs.


Why Slow-Release Vitamin C?

Timed-release or slow-release Vitamin C supplements are designed to be longer-lasting. Since Vitamin C is water-soluble, any excess is quickly excreted. A slow release helps your body absorb the amount it needs in smaller doses. This process may also be easier on your digestive system.


Are Vitamin C Supplements Vegan?   

Vitamin C is vegan. But many Vitamin C gummies may have gelatine . Make sure you buy from a reputed source or check the ingredients carefully. 


What are Bioflavonoids? Why Do We Need Them?

Bioflavonoids are plant-based antioxidants found in various fruits, vegetables, nuts, and green and black tea. Bioflavonoids can help reduce damage from oxidative stress[12],[13] which slows aging, cancer, help lower the risk of coronary artery disease, and boost brain function[14]. Some research suggests that bioflavonoids may help fight allergy-related conditions like allergic rhinitis and atopic dermatitis[15]

Bioflavonoids boost the transport and effect of Vitamin C in your body[16]. So, you may prefer Vitamin C supplements with bioflavonoids
