Is there an upper limit for Vit C?

An excessive amount of vitamin C is usually harmless – unless the overdose is 1 gram per day or more. The result of this can be nausea, stomach cramps and in rare cases kidney stones.

The daily requirement of vitamin C is approx. 95mg for women and about 110mg for men. In about this amount, the body can also absorb well. The rest is excreted over the urine.

Good luck!

The Federal Institute for Risk Assessment BfR has already published an opinion on this. They say that up to 1000mg a day may not be at risk.

You need a maximum of 100 mg of vitamin C every day. Kidney stones can be formed in a longer-term overdose.

Not everyone gets kidney stones, and with a single-use dose, little to nothing will happen, but “for a longer-term overdose” and people who already have a pre-damage of the kidney. They tend to form kidney stones.
