Hi. I just received the products. There's a lot of Vitamin A in there. That won't be toxic if I take 6 scoops a day?
Vitamin A, one of my favorite subjects. The reports of its toxicity are greatly exaggerated, perhaps because vitamin A competes with many cancer chemotherapies - and studies have shown vitamin A works better to halt cancers.
Linus Pauling recommended 25,000 iu daily of vitamin A, and the World Health Organization gives large shots to kids in the third world, i.e., between 100,000 and 300,000 iu of vitamin A (sometimes more). These shots keep these kids from going blind before they die from infection.
In this wonderful book by Roger J. Williams, https://riordanclinic.org/wp-content/uploads/2014/12/The_Wonderful_World_Within_You.pdf Williams reveals the finding that we require 20 times more vitamin A during reproduction than is required for ordinary growth and maintenance.
Most of the attacks on vitamin A are based on the facts that the vitamin is fat soluble (true) and is retained in the liver (true), but neither of these truths make it toxic. Vitamin A is needed daily. Mammals have evolved such that their livers store the vitamin for times of shortage (say when Bears hibernate) and during times of shortage the vitamin is slowly dripped into the blood stream from the liver.
A close associate of Roger J. Williams wrote this article on vitamin A toxicity - there really isn't any. The only death from a vitamin A overdose that can be found in the medical literature was a person who drank gallons of carrot juice (Beta Carotine!). https://www.vitamincfoundation.org/journal/mega2.1.html
But your question does beg another question: Why would you be wanting six scoops of Pauling's therapy - six servings - per day? We recommend 2 or 3, and if you are looking for these higher dosages of vitamin C and lysine, then it might be wise to take the extra servings be from Cardio-C (with no extra ingredients)
