It is very surely not. Too high doses cause kidney problems in fish and humans alike.I'm curious, why is this high vit C content is required by your fish in the first place?
What amount of vitamin C would be too high of a dose for guppies? When I research on them they find that 1000 mg/kg is required for optimal growth. Sometimes even 2000 mg/kg of vitamin C.It is very surely not. Too high doses cause kidney problems in fish and humans alike.
Fish vitamins like JBL Atvitol or Sera Fishtamin added to the food or only some drops directly to the tank 1-2x a week is enough.
Guppies.What kind of fish are we feeding?
Tetra's Goldfish Flakes says they are enriched with Vitamin C, haven't seen amounts or anything.
Pass. I always only bred cichlids and while yes, providing Vitamin C is an essential, I am very sure unless your livelihood depends on mass-producing (5000 specimens/week) guppies you are overdoing it when you go into such details.What amount of vitamin C would be too high of a dose for guppies?

Could you please give a specific source of the lethal dose of vitamin C for fish? When I look up LD50 I get different results depending on the animal that are a little more than 10 times the amount I’m looking for.Pass.

A good quality multivitamin mix additional to high quality live and frozen food will do more for your fish than deciding whether you need 1 or 2 grams of Vitamin C per kilogram of fish food.
If you want to know how much is too much, look up the LD50 for Vitamin C. That's the dose at which 50% of animals die from overdosing.
The species is irrelevant. The LD50 of Vitamin C is 11.5grams per kilogram body mass. Calculate it yourself for a 5 gram fish.Could you please give a specific source of the lethal dose of vitamin C for fish?

RayClem: I did not. You copied the wrong user name. It was the OP.MacZ referenced a study based on guppies, but looking at requirements for optimal growth.
MacZ quoted a dosage rate of 1000 mg per 1 kg.
Sorry, sometimes I get confused by the multiple quotes.RayClem: I did not. You copied the wrong user name. It was the OP.
My point was that this approach is pretty useless, as one single vitamin alone is not going to make or brake a breeding project, especially not on a non-commercial level.
I’m currently giving New Life Spectrum Optimum Flakes with Ocean Nutrition Spirulina Flakes. New Life Spectrum because of its high fiber content, carbohydrates, and vitamin C content. Ocean Nutrition as a source of probiotics. Seachem NutriDiet did have probiotics and an even higher vitamin C content than NLS, but they seem to have less of a broad amount of probiotics for different purposes compared to Ocean Nutrition.It's been a very long time since I kept fancy Guppies. About the only fish foods available to me at the time were flake foods manufactured by Wardley & Tetra.
I really didn't pay a lot of attention to the nutritional content.
Despite my fishkeeping inexperience and lack of quality food choices, the Guppies flourished & reproduced at the usual hyper accelerated rate.
Decades later, with the modern availability of numerous brands of nutrient rich fish foods, I've become somewhat of a food snob feeding only NLS, Omega One & Tetra Min.
My point to the OP is, your Guppies are likely going to do just fine & produce multitudes of babies, if you provide the proper water parameters & feed a quality commercial fish food. No need to be overly concerned about vitamin C.
My food recommendation for your Guppies would be New Life Spectrum Thera +A.
