Broccoli and cauliflower are members of the Brassica oleracea species, a diverse family of vegetables that also includes cabbage, kale, and Brussels sprouts. Despite their similar genetic background and low-calorie nature, a deeper look at their nutritional profiles reveals notable differences in their vitamin content. Understanding these distinctions can help you make informed decisions to best meet your dietary needs.
The Vitamin Face-Off: Broccoli vs. Cauliflower
While both vegetables are packed with nutrients, a head-to-head comparison shows that broccoli often takes the lead in many key vitamin categories. However, cauliflower has its own nutritional strengths that should not be overlooked.
Ascorbic Acid (Vitamin C)
When it comes to vitamin C, broccoli is the clear winner. A single cup of raw broccoli offers a massive 90% of the Daily Value (DV), while the same amount of raw cauliflower provides around 57% of the DV. Vitamin C is a powerful antioxidant essential for immune function, collagen production, and skin health.
Vitamin K
Another significant victory for broccoli lies in its vitamin K content. Broccoli offers a remarkable 77% of the DV for vitamin K in one cup, which is crucial for blood clotting and bone health. In contrast, cauliflower contains only 14% of the DV for vitamin K.
B-Vitamins
This is where cauliflower shines slightly brighter. A cup of raw cauliflower contains more vitamin B6 and pantothenic acid than an equal serving of broccoli. Both vegetables, however, provide similar amounts of folate (vitamin B9), which is important for cell growth and metabolism.
Vitamin A
Broccoli contains a notable amount of vitamin A, particularly in the form of beta-carotene, which is vital for vision and skin health. White cauliflower contains very little vitamin A.
More Than Just Vitamins: Minerals and Antioxidants
Beyond their vitamin content, both cruciferous vegetables are rich in other beneficial compounds. They are low in calories and high in fiber, contributing to digestive health and weight management. They also contain powerful antioxidants, such as sulforaphane, which have been studied for their potential anti-cancer properties.

Benefits of Choosing Broccoli
- Superior vitamin C and K: Excellent for immunity and bone health.
- Higher fiber content: Better for digestive health and satiety.
- Antioxidant richness: Contains beneficial compounds like lutein and zeaxanthin for eye health.
Benefits of Choosing Cauliflower
- Rich in choline: An essential nutrient for brain development and cell membrane integrity, which is more abundant in cauliflower.
- Lower carb count: A popular, low-carb alternative for dishes like rice and pizza crust.
- More pantothenic acid and B6: Contributes to energy metabolism.
The Final Verdict
So, does cauliflower have more vitamins than broccoli? Overall, broccoli contains a higher concentration of several key vitamins, particularly vitamins C and K. However, cauliflower is not nutritionally inferior; it is a richer source of choline and certain B-vitamins. Both are low in calories and high in fiber, and their unique antioxidant profiles make them both valuable additions to a healthy diet. The ultimate winner is the one you enjoy eating, as incorporating either into your regular meals will boost your nutrient intake.
If you're looking for a higher dose of immune-boosting vitamin C and bone-strengthening vitamin K, broccoli is the better choice. If you're on a low-carb diet or seeking more choline for brain health, cauliflower is the ideal vegetable. The best strategy is to enjoy both regularly to get the widest range of vitamins and nutrients. For further nutritional details on both vegetables, check out the information provided by Healthline.
