Vitamin supplements are an interesting thing. Some claim their useless, others swear by them. Vitamins are indeed a vital part of our immune system however the best and most reliable way is always through a well prepared, well considered diet. However, in the event of self isolation due to an emerging situation you may need to subsist on a far less nutrient rich diet which is where these will come in. Now one must remember different vitamins will be absorbed at different rates, for instance a solid pill will always be absorbed slower than say a dispersible etc etc, you also need to be aware of dosage. For instance it's next to impossible to overdose on Vitamin C however it is fairly easy to overdose on the oft forgotten Vitamin K. Your best bet is to splurge out a little on a mid range multi vitamin if you fear you are likely to end up in a self isolation scenario (and of course compensate for any who will be relying on you such as children or immediate family). A mid range vitamin usually includes full dosages of the aforementioned Vitamin K, Iron and other oft over looked vitamins as well as the usual suspects of A, B, C, D etc. If operating on a budget however the dollar store cheap ones are a fine alternative, all that matters is that you are at least looking at making sure your system will not suffer from deprivation. As for other supplements there are options such as Allicin (the healthy component of Garlic in a concentrated form), Oregano Oil, Turmeric and so forth which all do similar things in different ways. If you wish to look at these I would sincerely advise doing some research and double checking how they react to what. For instance some were trying to get people to buy Elderberry syrup, a fine item to improve your immune system, however an item that can cause serious issues if one enters a cytokine storm which is a realistic occurrence with this virus in a worst case scenario. Knowledge is key in this area.
Right gentlemen, I've been writing this for a few hours now and need to actually get to sleep. I'll continue with everything tomorrow night, same as tonight. Just remember, you'll likely be fine, just make sure you take care of yourself and your family. If you haven't gotten basic supplies yet now is the time to prioritise, do so quickly before more of the general public notice their little distractions are beginning to buckle. Oh and don't get scalped please. There is a number of vile degenerates praying on people on a number of sites including the usual flea markets such as Ebay and Amazon, keep your head and think about what you definitely do need and work within reason.
