Cyanidin 3-Glucoside Supplementation

Cyanidin 3-glucoside

Cyanidin-3-glucoside, often abbreviated as C3G, is a natural plant pigment and antioxidant belonging to a group of compounds known as anthocyanins. Anthocyanins are responsible for the red, purple, and blue colors in many fruits, vegetables, and flowers.

This pigment gives foods like blackberries and blood oranges their bright red and purple hues. Structurally, the attached sugars make cyanidin 3-glucoside more stable and bioavailable than other anthocyanins. It can be readily absorbed intact in the small intestine and circulate in the bloodstream.

Once absorbed, cyanidin 3-glucoside accumulates in certain tissues such as the eyes, heart, prostate and kidneys, which are all sites where its antioxidant effects can be beneficial. Studies show it exhibits strong antioxidant activity, which helps quench damaging free radicals and reduce inflammation.


  • Enhanced cognitive function and neuroprotection
  • Lowered risk of cardiovascular disease
  • Anti-cancer effects against certain types of tumors
  • Improved vision and eye health
  • Increased insulin sensitivity and anti-diabetic effects
  • Enhanced skin protection against UV radiation

Get the most out of it

While eating whole foods rich in cyanidin 3-glucoside can provide benefits, supplements offer a more concentrated source. If you’re considering taking a cyanidin 3-glucoside supplement, here are some tips to get the most out of it:

Look for a reputable brand providing high purity cyanidin 3-glucoside without unnecessary fillers. A supplement standardized to contain a specific amount of cyanidin 3-glucoside is ideal.

Follow dosage recommendations on the label, usually in the range of 30-120 mg per day for general antioxidant support. Consult a healthcare provider to determine the right dosage for your individual needs.

Take supplements consistently with food to enhance absorption. Some fat in a meal can also help increase absorption of this water-soluble compound.

Drink plenty of water when taking cyanidin 3-glucoside to support systemic circulation and delivery to tissues.

Cyanidin 3-glucoside works best alongside a healthy diet high in fruits, vegetables, lean proteins, whole grains and healthy fats. A supplement cannot replace good nutrition.
