Short answer: the evidence is mixed and limited, and these products do not replace training. Talk to your vet before giving your dog any supplement.
What VCA says
VCA lists some calming products, such as supplements with L-theanine, which it says may have a calming effect based on initial studies, and synthetic pheromones sold as diffusers, sprays or collars. It also lists Bach flower remedies and a probiotic diet. It describes them as options to discuss with a vet, not as cures.
What the AKC says
The AKC explains that calming diffusers and sprays work by copying certain scents, such as the mother dog's, and notes that this is a fairly new area.
What actually changes behavior
Fear and anxiety respond best to a plan: a vet check, management and gradual training. See a safe space for fireworks and the reactive dog threshold.
Get the right help
Do not give any supplement or product without asking your vet first, especially if your dog takes medicine.
This article is general education, not veterinary advice. If your dog seems unwell, is in pain, or something changed suddenly, call your vet. If it could be an emergency, do not wait.

What actually changes behavior?
A vet check, management of the setup, and gradual training. Products are at most one small part of that.
