Let's talk iron for a moment.
More specifically - let's talk red blood cells and hair.
If you'll recall over the past 2 years - this whole hype about ventilators and O2 levels dropping. Ventilators, while great in theory - won't do anything if you don't have the red blood cells to absorb the O2. Iron (hemoglobin) is required to form red blood cells (in the bone marrow) - and without the iron to bind the O2 (ferratin/hemoglobin) you can pump all the air into the lungs you want, but you won't have any O2 in the blood/body because you don't have the iron in the form of hemoglobin to absorb that oxygen (O2).
Iron is one of the most important nutrients for hair growth. If your body doesn't have enough iron to support adequate O2 (oxygen) levels - then your body will prioritize the iron use in the body to make red blood cells, at the expense of hair.
Now, what lately has been dropping O2 levels and causing hair loss in people? You can put 2+2 together here.
Iron also needs Vitamin C to absorb it - and coffee blocks the absorption of Iron in the body (due to its acidity).
Below is a very reasonably priced Iron that is fairly well formulated to be well absorbed, as well as has a natural non-ascorbic acid Vitamin C to help the body utilize the Iron. One of the problems with Iron supplements is that if you don't take Vitamin C with it - you won't get the Iron you take utilized by the body, and that can cause problems with Iron build up that hasn't been utilized in the body. It is also a chelated version that helps to negate the digestive issues that come along with supplementing with Iron that can happen in people. https://amzn.to/3F2u8lR
"Iron is an important component of hemoglobin, a protein in red blood cells that delivers oxygen to tissues throughout the body. It is also a part of myoglobin, a protein that helps muscle cells store oxygen, and ferritin, the body's main iron storage protein found in the intestines, liver and spleen. Iron bound to ferritin is readily mobilized to meet the body's demands. Ferrochel brand iron bis-glycinate was developed using unique patented chemistry, allowing it to be absorbed rapidly from the lumen of the intestines into mucosal cells and then released for transport throughout the body. The intestinal mucosal tissue tightly controls the release of Ferrochel, supporting the safety profile of this iron amino acid chelate. In a double blind, randomized, placebo-controlled trial, iron supplementation supported healthy ferritin levels and enhanced energy and well-being in female subjects. Another report emphasizes the importance of maintaining healthy serum ferritin for optimal performance in elite female athletes. In another randomized trial, iron supplementation or a high iron diet supported cognitive wellness and moderated fatigue in women of childbearing age. Ester-C is a natural, non-acidic water-soluble form of vitamin C that is distinguished by its unique chemical composition and biological activity. It is manufactured in an exclusive, water-based process that results in a mixture of naturally occurring vitamin C metabolites, including ascorbate, dehydroascorbate, and threonate. Vitamin C aids in the absorption of iron and the formation of red blood cells. Research indicates that vitamin C supports healthy hemoglobin levels."
Another supplement to help absorb Iron, Lactoferrin: https://amzn.to/3EYcC28
Nearly all lactoferrin sadly does not contain Iron in the supplement - so while it will help with absorption and utilization and turning it into hemoglobin and red blood cells, it doesn't supply the iron itself to create the hemoglobin and red blood cells. Taking an appropriate Iron supplement along with Lactoferrin will help boost the effects of both - and help negate the build up of unused Iron in the body (as well as the digestive discomfort of the Iron not being able to be absorbed).
Another solution is to juice spinach along with lemons. The spinach provides the Iron, and the lemon provides the Vitamin C to help the iron absorption. The most natural route such as this is obviously the best way to do it, but it's not always the most cost effective or convenient. Commercially farmed (even organic) spinach has a fraction of the Iron content it used to sadly - so getting a more "home grown" or "farmer's market" spinach will be drastically more effective than even organic farmed spinach (due to even organic produce not being bio-regeneratively farmed).
These solutions aren't completely perfect - but they help. You can choose what's best for you, and you'll most likely just have to try a few things to see what works best for you.
Hopefully this is helpful information to you - and can help keep your health at its maximum during these times.
*Side note - an aerosolized poison/toxin of some kind could cause red blood cell rupture and deformation and death which would mimic the symptoms of a virus. This is a longer discussion for a different day - as obviously there is a lot of information (much of it speculative) to cover and discuss that we don't have time for in this post.
This information should not be discounted, but at the same time - the solutions still remain the same to maintain hemoglobin/red blood cell levels*
