I had covid 19 last June, but after 2weeks of quarantine, I was tested negative. But, I am now experiencing the same post-covid symptoms as with ineedanswers38, although I never had diahrea. I've been drinking powdered turmeric dissolve in hot water, but I don't feel any improvement, although I always discharge gas(fart). I guess I'll try this flax & Chia seeds with yogurt. I also tried omeprazol but still same.

Make sure the flax and chia seeds are not from China, Turkey, Africa, etc. They are contaminated with heavy poisonous heavy metals (cadmium-contamination-in-flax). You can NOT trust packaging! They will say "packaged in US", that is not the source of the item. I had to throw out 2 lbs. of flax seed from Amazon, even though it stated non-GMO, Organic, etc. Amazon does not give a rats-ass about you, only about corporate profits. You can check online regarding each countries heavy metals levels. Stay away from products from those countries.
Some of the most common food ingredients may be depositing toxic heavy metals into your body, contributing to the development of disease. Vegetable oils, food colors, corn syrups, and preservatives are the top sources of these ingredients—found mostly in processed food products—that will contribute to your body’s burden of heavy metal exposure. Although few studies have been conducted to determine the concentrations of heavy metals in food products, there seems to be some evidence to suggest the most common toxic heavy metals found in the food supply are inorganic mercury, lead, cadmium, and arsenic.
Why would FDA only look for organic mercury and not inorganic mercury, when the evidence suggests inorganic mercury is a widespread contaminant in the food supply?
Inorganic mercury in the food supply is an inconvenient truth. Fixing exposure to inorganic mercury is harder than simply reducing your intake of certain foods; however, reducing your exposure is still extremely important.
There are certain amounts of heavy metals, such as arsenic, lead, and mercury, that are allowed in these food ingredients. This does not eliminate the significant risk of heavy metal exposure—these metals are able to displace zinc from the metal carrier protein metallothionein (MT), and this can lead to zinc losses from the body. Zinc losses adversely impact health by creating inflammation and stress. Heavy metal exposures and/or low zinc status are associated with Alzheimer’s disease, autism, hyperactivity, pica, type 2 diabetes, insulin resistance, and heart disease conditions.
The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests. Most of the tests took place at the Nevada Test Site (NNSS/NTS) and the Pacific Proving Grounds in the Marshall Islands and off Kiritimati Island in the Pacific, plus three in the Atlantic Ocean. Ten other tests took place at various locations in the United States, including Alaska, Nevada other than the NNSS/NTS, Colorado, Mississippi, and New Mexico.
Unfortunately our soils and oceans are heavily contaminated!
