[Product Question] Can you use The Ordinary Niacinamide and Zinc Solution with Vitamin C?

Beauty Tips For Body Care
The Ordinary clearly says to not combine the Niacinamide solution with Vitamin C, but an article I read (https://www.byrdie.com/niacinamide-and-vitamin-c-4845348#so-can-you-use-niacinamide-and-vitamin-c-together) even advices to do so and says this is based on outdated studys. I read that it‘s okay to be used together on other sources as well. Whats the opinion of the SCA community?
