The best source of vitamin C isn't an orange.
Oranges are the default answer. They're nowhere near the best. Here's the honest ranking of where vitamin C actually comes from — and the berry that towers over all of it.
Far less, gram for gram.
The orange myth
We were taught the wrong fruit
Somewhere along the way, "vitamin C" became shorthand for "orange juice." It stuck — but the orange is a middling source at best. Bell peppers beat it. Kiwis beat it. Strawberries beat it. And a small orange berry from the mountains carries several times more than any of them.12
The orange: famous, not exceptional
At ~53 mg per 100 g, one orange roughly covers a day's vitamin C — useful, but unremarkable. It earned its reputation through marketing and availability, not because it's the richest thing on the shelf.2
The ranking
Vitamin C, by food — the honest chart
Milligrams of vitamin C per 100 g
Approximate values · USDA FoodData Central and peer-reviewed analyses
A couple of obscure tropical fruits — acerola and camu camu — test even higher, but you won't find them fresh at a Canadian or US grocer, and they're far too sour to eat by the handful. Among foods you can actually buy and enjoy, sea buckthorn leads.1
One serving
A single serving, several days of vitamin C
Well past your daily target — in one go
The recommended daily intake of vitamin C sits around 75–90 mg.3 At roughly 400 mg per 100 g, sea buckthorn clears that several times over. You're not topping up — you're filling the tank, with room to spare for the days you forget.
Why it matters
What vitamin C actually does
Immune support
Contributes to the normal function of the immune system — one of vitamin C's best-established roles.
Collagen and skin
Required for the body to synthesise collagen — the structural protein behind firm, resilient skin.
Antioxidant defense
Helps protect cells from oxidative stress caused by everyday free-radical exposure.
Iron absorption
Improves how well your body absorbs plant-based (non-heme) iron from the same meal.
These are physiological roles backed by major nutrition authorities — not health cures. Vitamin C supports these systems; it doesn't treat disease.3
Beyond the number
It's not just milligrams — it's the company it keeps
Whole food beats a single isolated nutrient
A vitamin C tablet gives you vitamin C and nothing else. A whole berry delivers it alongside the antioxidants, carotenoids and fatty acids it naturally travels with — the way your body evolved to take it in. Sea buckthorn is unusual because that "company" is exceptionally rich:
The everyday way to get it
Skip the supplement aisle
You don't need a synthetic tablet or a pile of oranges. A cold-pressed sea buckthorn purée keeps the vitamin C and its cofactors intact in a single daily pouch — the whole berry, nothing stripped out.
Human Renaissance Sea Buckthorn Purée
One wild berry, cold-pressed into single-serve pouches — high vitamin C with the omega-7, vitamin E and antioxidants it naturally comes with. 60 pouches = a 2-month supply, free shipping to Canada and the US, 60-day guarantee.

FAQ
Common questions
What food has the most vitamin C?
Among everyday foods you can actually buy, sea buckthorn leads at roughly 400 mg per 100 g — far above oranges (~53 mg), kiwi (~93 mg) or red pepper (~128 mg). A few rare tropical fruits like camu camu test higher but aren't sold fresh.12
Is sea buckthorn higher in vitamin C than oranges?
Considerably more, gram for gram. It's one of the richest accessible plant sources of vitamin C.1
How much vitamin C do I need a day?
Most adults need around 75–90 mg daily. A serving of sea buckthorn provides several times that amount.3
Is whole-food vitamin C better than a tablet?
Whole foods deliver vitamin C alongside the antioxidants and other compounds it naturally occurs with, which a single-ingredient tablet can't replicate.4
