National Vitamin C Day: What You Need to Know

We won’t drown you in boring scientific shenanigans, but here’s the inside scoop on vitamin C!

Historically, the widespread recognition of vitamin C's benefits grew significantly in the 1970s, partly influenced by notable advocates like Linus Pauling, as noted by the Harvard School of Public Health.Historically, the widespread recognition of vitamin C's benefits grew significantly in the 1970s, partly influenced by notable advocates like Linus Pauling, as noted by the Harvard School of Public Health.

Vitamin C is considered a “water-soluble vitamin,” which means it can dissolve in water. Since our bodies are 60% water, we cannot store it in our cells and tissues, so regular consumption is needed to maintain proper levels!

Vitamin C is recognized for its role in supporting immune function and is also involved in various metabolic processes, according to research. On top of this, it’s a potent antioxidant and acts as a critical component in collagen production.

So yes, there are many reasons why vitamin C is the queen bee. And now that we know the backstory, let’s delve into the best ways to consume it!

Best Ways to Consume Vitamin C

If you’re feeling inspired to add more vitamin C to your routine, here are the most effective ways you can get started right away!

Vitamin C Day

Choose a High-Quality Supplement

We get it, there are so many vitamin C supplements whirling around the market, typically either in gummy, powder, liquid, or tablet form. With packaging that pops, you might be inclined to pick the first product that catches your eye.

But don’t act so quickly.

It's important to choose vitamin C supplements carefully, as some may contain added sugars and artificial flavorings. Many vitamin C supplements today are filled to the brim with added sugars, artificial flavoring, and mystery ingredients. So when choosing one, check the label to see that the ingredients are as pure as possible, and follow the Good Manufacturing Practices 2. Any brand that follows these guidelines is likely trustworthy. Also when perusing supplements, make sure you follow the recommended daily amount, according to the Mayo Clinic3.

Sip on a Cold-Pressed Vitamin C Drink

Although a stand-alone supplement might get the job done, we think it’s a bit more fun when more flavor and nutrients are involved! And yep, you guessed it. Suja Organic can certainly help in this department.

As you might know, all of our cold-pressed juices are crafted with real, organic ingredients, making wellness 100% accessible. All of our juices and shots are also USDA Certified Organic, Vegan, Gluten-Free, and Soy-Free!

"I love that this comes in a huge bottle! The flavor is crispy and has a tiny hint of spice at the end. Not as strong as the lemon or ginger so I can drink it on more of a regular basis without irritating my throat from the Cayenne pepper. The coconut water makes this a drink perfect for breakfast! Pour it over crushed ice and enjoy!" - Suja Verified Buyer, Citrus Immunity Vitamin C Juice, Trluckey
