For vitamins, as directed (on the dosage information that comes with the product) - especially vitamins A & D, which are fat soluable. It is possible to overdose on A & D (not deadly but can cause illness). As for pine needle tea, considering that First Nations people used it as a treatment for scurvy, it’s biggest benefit is a boost of vitamin C & therefore immune system support - so one cup a day. These are all recommended as prophylaxes against “COVID” (which has never been isolated as a unique pathogen), but also treatment of infection to help the body fight. The injections cause genetic modification of cells in order to get them to produce the same proteins as the “virus”; the resulting immune response will be similar to actual infection (other adverse affects are more related to other dangerous ingredients - not everyone has immediate adverse effects. These treatments cannot reverse the genetic changes. I’m sorry, I cannot lie & give you false hope.
