Thats what the wife and I have been doing. The vitamin D3 is the most important, it is usually created in the body with exposure to sunlight.
That’s what my girlfriend (who incidentally is from Missouri) and I have been doing. We take those three plus Quercetin and Famotidine, daily.
A coworker has a good friend who had contact with Secret Service agents while setting up the stage and lighting for one of Trump’s rallies over the summer. Those five substances are what the Secret Service guys take daily. We call it the “Secret Service Cocktail”.
We even got fancy and bought 14-day pill organizers to simplify taking them in the morning. We’ve been taking it for about four months now, five pills down the gullet every morning, and it isn’t causing us any problems, digestive or otherwise.
We have no proof it’s actually doing any good, but neither of us have been ill in the slightest except for my gf’s bad allergies. But it’s not doing any harm, it’s cheap, and if it’s good enough for the guys who protect our president it’s good enough for us.
