Bioflavonoids are natural pigments that give plants their bright colors and are bursting with health benefits. Citrus bioflavonoids are mainly found in the edible pulp of citrus fruits, and they have many health promoting benefits. Bioflavonoids are natural pigments that give plants their bright colors and are bursting with health benefits.
Citrus bioflavonoids, including rutin and hesperidin , are part of a group that function synergistically with vitamin C to maintain healthy capillaries, encourage wound healing via the formation of collagen in connective tissue, and support a healthy immune system.
More and more research shows the bioflavonoid benefits of citrus. Here are some of those benefits.
Antioxidant Benefits
Why is citrus bioflavonoids good for you?
Research has found that citrus flavonoids prevent your body from producing free radicals, deactivate free radicals, and increase your body’s antioxidant defenses.
Anti-Allergy Benefits
The antioxidant effects of bioflavonoids appear to be especially potent against allergic conditions.
Research suggests flavonoids may help support the body's response to asthma, rhinitis, and dermatitis. Oxidative stress is associated with allergic conditions. The antioxidant power of bioflavonoids may be able to stop the process of an allergic reaction at its root.
Rutin and hesperidin are two of the more common citrus bioflavonoids that are associated with this effect.
As these ingredients reduce oxidative stress, studies have investigated if they also can help reduce the inflammatory response associated with seasonal allergies. For these citrus bioflavonoid complex benefits, it is thought to be the interaction between all the citrus bioflavonoids, not just one specific ingredient.
Neurological Benefits
Scientists believe that certain neurological conditions, such as dementia, Alzheimer’s and Parkinson’s disease, may be caused by oxidative stress. Since bioflavonoids reduce oxidative stress throughout the body, these compounds may help in preventing or reducing symptoms of these neurological problems. Research has studied bioflavonoids for their potential role in supporting brain health as we age. Other studies conclude that reducing oxidative stress protects your nervous system from damage, and antioxidants may even help your brain repair itself.
Cardiovascular Benefits
Scientists link coronary artery disease to oxidative stress and inflammation. Research has found that bioflavonoids are associated with cardiovascular health, and these compounds may help support your heart, veins, and arteries. Research suggests bioflavonoids may help support healthy blood flow and cardiovascular function.
One of our new products, Pathway Citrus Bioflavonoid Complex, features a spectrum of powerful compounds including, eriocitrin, narirutin, naringen, hesperidin, diosmin, didymin and hesperitin. Check it out!

Hesperidin is one of the most studied of these compounds for heart and vessel health. Research has looked at how it may help support soothethy blood flow. It may also reduce oxidative stress in the cardiovascular system. Naringin is another citrus flavonoid. A review points to its anti-inflammatory and antioxidant activity, which researchers continue to investigate.
The Skin and Vitamin C Connection
Choosing and Taking Citrus Bioflavonoids
Looking for the best citrus bioflavonoids supplements? Read the label for the actual compounds inside, not just a vague "complex" name. Quality citrus bioflavonoid supplements list their ingredients, like hesperidin and rutin, so you know what you're getting. Most people take them with a meal. If you take prescription medication, check with our pharmacists first, since grapefruit-derived compounds can interact with some drugs.
As far as citrus bioflavonoids dosage goes, there’s no recommended daily allowance since they’re not considered an essential nutrient. Supplement manufacturers provide different quantities in their formulations, so it’s really up to you and what the supplement label states to determine how many capsules or chewables you should take. Citrus bioflavonoids side effects are generally rare. When they do occur, they tend to be mild, such as temporary gastrointestinal discomfort, which may be reduced if the supplement is taken with food. You can find citrus bioflavonoid supplements in gummy form, but capsules and tablets will typically have more ingredients in them. A pharmacist can advise you on the best product, form and amount based on other supplements or medications you take.
Frequently Asked Questions
Are citrus bioflavonoids safe?
Citrus bioflavonoids side effects are minimal, and they are well tolerated for the majority of individuals. Grapefruit components may be problematic with certain medications, however. If you take any prescription medication, ask your physician or one of our pharmacists about possible interactions. We at Village Green Apothecary can help guide you through all of your current medications to see which ones work best for you.
When to take citrus bioflavonoids?
Most people take their citrus bioflavonoids dosage with a meal. Pairing them with food, especially a source of vitamin C, may help support absorption and ease digestion. There's no single "right" hour of the day. Pick a time you'll remember and stay consistent.
Are citrus bioflavonoids vitamin C?
No. Bioflavonoids from citrus fruit are not vitamin C, but they are related. The bioflavonoids belong to a different group of phytochemicals, and because they work with vitamin C, it’s not surprising that both may be found together in some supplements.
Are citrus bioflavonoids acidic?
The fruit itself is what makes it citrusy and acidic. The bioflavonoids are not the acidic part. That's the ascorbic acid, aka vitamin C. If a pure vitamin C supplement hurts your stomach, you might find that the bioflavonoid complex with meals is easier on your system. One of our pharmacists can help you figure out which type of vitamin C is best for you.
What Citrus Bioflavonoids Actually Are?
Citrus bioflavonoids are phytonutrients in the pith and flesh of oranges, lemons, and grapefruits like hesperidin, rutin, naringin, and diosmin. Bioflavonoids belong to the broader category of flavonoids and polyphenols, which have been widely investigated for their antioxidant capacity. Put simply, the bioflavonoids meaning in this case is: These are the pigmented antioxidants that fruits produce to protect themselves, and they’re typically accompanied by vitamin C.
