Can I take Vitamin C and Turmeric with black pepper together?

Why this happens

Turmeric can slow blood clotting, and vitamin C helps maintain blood vessel integrity but can have an additive effect on bleeding risk at high doses. Regarding kidney stones, vitamin C is broken down into oxalate, and turmeric contains high levels of soluble oxalates; together, they increase the 'load' on the kidneys.

This combination is generally safe for most healthy people at standard supplement doses. However, if you take blood-thinning medication (like warfarin or aspirin), have a scheduled surgery, or have a history of kidney stones, you should speak to your doctor before taking these together. Do not exceed the recommended daily dose on the packaging.

Bleeding disorders

Both vitamin C and turmeric can thin the blood and increase the risk of bleeding. You must stop taking these at least 2 weeks before any planned surgery and use caution if you take other blood-thinning medicines like warfarin or aspirin.

Kidney stones (renal calculi)

High doses of vitamin C can increase the amount of oxalate in your urine, which significantly raises the risk of developing kidney stones, especially if you have had them before.

Gallstones or bile duct obstruction

Turmeric can cause the gallbladder to contract, which may worsen symptoms or cause pain if you have gallstones or a blocked bile duct.

G6PD deficiency

Very high doses of vitamin C can cause oxidative stress and lead to the breakdown of red blood cells (haemolysis) in individuals with G6PD deficiency.

Alcohol

It is best to avoid or strictly limit alcohol when taking rosehip supplements. While there is no direct interaction, both alcohol and high doses of vitamin C can put strain on the liver or kidneys in certain individuals, and alcohol may worsen the inflammatory conditions rosehip is often used to treat.

It is best to avoid or strictly limit alcohol when taking turmeric supplements. Both alcohol and high doses of turmeric can put strain on the liver; combining them may increase the risk of liver irritation or damage.

Grapefruit juice

Grapefruit juice can interfere with the enzymes that break down certain compounds in your body. Because black pepper (piperine) is specifically added to turmeric to slow down its metabolism, adding grapefruit juice may further increase levels of the supplement in your blood, potentially increasing the risk of side effects.

Caffeine

Piperine (found in black pepper) can slow down the rate at which your body rids itself of caffeine. This may increase the effects of caffeine, leading to jitters, heart palpitations, or insomnia.
