Does Turmeric Affect Iron Levels? Unraveling The Connection

Prior studies conducted on animals have consistently demonstrated a significant reduction in iron absorption when whole turmeric or curcumin is introduced into their diets [39, 40, 41]. This effect is also observed in humans, where the consumption of whole turmeric has been linked to a substantial reduction in iron absorption ranging from 20% to as high as 90% [42]. This information, dated February 8, 2022, underscores the noteworthy impact of turmeric on iron absorption in both animals and humans.

While there is more extensive research available on the impact of black tea on iron absorption, it is worth noting that herbal teas, particularly those with higher tannin content, are believed to potentially hinder the absorption of iron in the body. Some herbal varieties that are reported to contain tannins include hibiscus and chamomile. Tannins are compounds that can interfere with the body’s ability to absorb dietary iron. Further studies and investigations are needed to fully understand the extent of this effect and its implications for overall nutrition. This information was last updated on June 2, 2023.

Polyphenols are a group of beneficial antioxidant compounds that can help reduce the absorption of iron in the body. These compounds are found in various dietary sources and are available in supplement form. Some well-known supplements rich in polyphenols that can potentially reduce iron absorption include milk thistle, green tea extract, turmeric, quercetin, and resveratrol. By incorporating these supplements into your diet or consuming foods rich in polyphenols, you can support your overall health and potentially regulate iron levels in your body more effectively.
