This is really a concern. The darjeeling is so good I'm getting addicted but
Tea in general has more fluoride than coffee which has none, but may be worth the risk for me
Get tired of coffee sometimes
Probably depends on tea growing region too
Fluoride In Tea: Risk, Ranking & Guide (Search 329+ Teas)

Fucking bummer, says all black teas tend to have more fluoride
I'm not gonna drink chamomile, fuck that
God dammit. Need to research and finr good looseleaf that doesnt have
Fluoride
Might have less fluoride in it than
Indian or chinese teas
The amount I drink is crazy makes me think I should actually look for a low fluoride tea
Tea may contain more fluoride than once thought, research shows -- ScienceDaily

A Risk of Fluoride Toxicity
In recent years, there have been a number of reports documenting skeletal fluorosis in the United States among heavy tea drinkers. Dr. Michael Whyte, who has authored several of these studies, cautions that “many” tea drinkers are currently receiving fluoride doses that put them at risk for skeletal fluorosis. (Whyte 2008). In Whyte’s studies, the tea drinkers who developed skeletal fluorosis had been misdiagnosed for years as suffering from arthritis and/or fibromylagia. In Whyte’s most recent study, a Georgia woman had crippling skeletal fluorosis for up to 18 years before being correctly diagnosed. (Whyte 2011). As some authors have noted, “it is certain that some heavy-tea drinkers suffering from fluorosis from tea-drinking might not be diagnosed.” (Yi & Cao 2008

Newby Teas, predominantly owned by a British registered charity, conducted an independent study to test their own product and to enlighten tea drinkers by focussing on community health and the welfare of society. They commissioned “Eurofins”, a globally recognized laboratory, to conduct lab tests for fluorides at their laboratory in Wolverhampton, UK. 31 samples of teas from various popular international brands were tested to assess the fluoride levels in their teas.
Out of the samples tested, 95% of Newby Teas were recorded to have the lowest fluoride levels from 0.25 – 0.35 mg of fluoride per cup of 200 ml. Tests further revealed some of the most known & premium tea brands consisted of up to 1.06 mg fluoride content per cup, which if consumed regularly, could severely compromise bone health, especially of children, women and elderly people.
When Newby Team was questioned about how they maintain low fluoride levels, Mr. Nirmal Sethia, Founder of Newby Teas stated, “Matured tea leaves absorb the most fluoride. It is essential to use the first or second flush teas only. As the tea leaf matures over the time, the fluoride content increases.”
Sethia further added, “While the figures don’t look too bad for someone drinking the occasional cup of tea, if several cups are consumed per day, this could have a significant negative effect on an individual’s health. We will continue to monitor the situation for our product control and comparative reasons. While this is not compulsory by law, we believe it is our ethical duty to do so.”
The tea plant (Camellia Sinensis) extracts fluoride from the soil which accumulates in its leaves. Tea is a rich source of fluoride, which is healthy in moderation. A report published by the University of Derby and the then HPA (Health Protection Agency) showed that some so-called economy teas, which are made from older leaves containing increased levels of fluoride, had dangerously high levels of fluoride, ranging up to 1.59 mg per cup.
World Health Organisation (WHO) estimates the popular beverage, tea, can trigger risk of bone damage in its consumers due to its fluoride content. A daily consumption of over 4 mg for minors and 6 mg of fluoride for adults can cause deadly ailments such as skeletal fluorosis, osteoporosis, an overall deterioration of bone health, and other consequential illnesses.
But they have black tea too
Idk
Everybody says black tea has more fluoride but nobody is comparing
Different types of black tea from different regions
White tea is supposedly great for antioxidants and japanese green tea has less fluoride than chinese
It's not the most important thing but do u think we can research which black teas are safer fluoride wise and
What ray peat says about mitigating that stuff
It seems like there should be a way to test fluoride in various teas and find black tea without it
Since it comes from the soil in an area and wasnt a problem inherent to tea
But india and china is main black tea producers so fuck
Idk tho this is like almost as necessary for me as a good cigarette used to be so I'm not giving up tea
There is a charleston sc black tea plantation

Risk Assessment of Fluoride Intake from Tea in the Republic of Ireland and its Implications for Public Health and Water Fluoridation
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4808922/
Skeletal fluorosis is a reversible effect characterized by deficient mineralization of the bone, leading to changes in bone structure and increased risk of fractures. Skeletal fluorosis is endemic in several countries where the potable water sources naturally contain high fluoride levels (> 4 mg/L), and where water consumption is high due to hot climates (EFSA 2013). Fluoride intakes of above 6–8 mg/day may increase the risk of bone fractures (EFSA 2013; NHMRC 2017a; WHO 2011, 2017).
Soils are clearly the
main source of fluoride and other trace elements
for the tea plant. However, in order to boost tea
yields, most tea growers use nitrogenous
fertilisers, which may further increase the fluoride
content in tea by (a) contributing additional
fluoride, and (b) making the soils acidic by
producing hydrogen ions (H+
) via nitrification
(NH4
+
+ 2O2 g NO3
-
+ H2O + 2H+
) induced by
bacteria present in the soil (Ishibashi et al., 2004).
This in turn increases the mobility and
consequently the bioavailability of fluoride for
uptake by the plants (Fung and Wong, 2002).
Other factors that may influence the fluoride
content in tea infusions include leaf age (Shu et
al., 2003) as well as genetics factors.
The World Health Organisation (WHO), in
light of the associated health effects of fluoride
has set the guideline for fluoride in drinking water
at 1.5 µg F- ml-1 (WHO, 2011). However, the upper
limit for fluoride uptake from tea is not included
in the current Kenyan black tea quality standard
(KS 65: 2009). Based on the guideline for drinking
water, black CTC tea may be regarded as safe for
consumption with respect to fluoride conten
Found a citation somewhere saying highland teas also have less fluoride than lowland teas
Which makes sense in terms of watersheds
Anyway if you combine maps of watersheds, altitudes, and this map of global fluoride concentrations , it should be possible to find
did you see this already? site looks sketchy overall but they have a searchable DB on this page: https://truthaboutfluoride.com/fluoride-in-tea/
Yes, I did. But the sample seems large but they dont look for black teas from america , africa, Japan or just highland areas that may have lower fluoride so
It mostly seems like the evidence is just saying that in general white or herbal teas are best which I already knew but it's not a large enough sample of black yeas from different regions to find a safe one
Can one chelate fluoride I wonder
Also they set a different cutoff from the who one
So the table is actually a bit helpful if you take that into account. But I'm gonna ask them to test or add other brands to it
They say you can contact them to add other brands
Maybe for health reasons tea needs to be in moderation and rotates just in case one brand high fluoride

No, I want low fluoride black tea
It's about something that's a small pleasure for me where I dont have much
Honestly I wouldn't sperg out about the fluoride except for the fact that I already may have problems with my bone fusing
So Nepal, bhutan and a variety of the eastern and southern regions look good for tea with less fluoride
