Methionine/Cysteine restriction increases longetivity AND energy expenditure
-
interesting stuff ,
looks like part of the effect is from that increase of thyroid hormone / signallingThyroid hormone increases the FGF21 (but high dose , though does improve with more time, is tissue dependant) https://pubmed.ncbi.nlm.nih.gov/20236931/
& Thyroid hormone also increases the PEPck seen in cysteine restriction
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1135718/
and thyroid hormone & receptor expression is increased by methionine restriction
https://www.sciencedirect.com/science/article/pii/S1756464620300062
main roles Phosphoenolpyruvate Carboxykinase plays https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2785631/

My goal has been to have the glycine dominate the other aminos, if that makes sense. So I’m taking more of it. I’m trying to minimize the other ones to some degree.
The glycine has tremendously helped me in a number of areas: improved sleep, improved mood, muscles, skin. It makes you kinda chill…at least it does for me.
I have the MTHFR mutation and Chris Masterjohn says it helps with methylation. That’s another reason I take it.
- An interesting side note: I don’t lift weights, but occasionally I will jump on my Total Gym and do a workout. As a result of taking the increased glycine, It appears that my muscles are more toned and firmer. Without much exercize.
Fyi, I don’t always take straight glycine- I use gelatin and collagen as well. I also don’t always get 20 gms. But I do aim for higher amounts. I mix it in my milk.

I’ve read that thru modern farming practices, our soils are depleted of selenium, so supplementation of it is advantageous.
I take 200 mg. of selenium every few days or so. Then I’ll stop for a week or two so as not to overload my system.

@cs3000
T3's FGF21 increase depends on PPARa, so we got another player in the game.This is what Travis wrote on the PPARs:
"The activation of the PPAR receptors can be considered a good thing, and their first described function was to upregulate peroxisomes—small subcellular organelles which metabolize excessive prostaglandins and fats. I get the impression that the activation of these could represent the 'resolution stage' of inflammation—an idea which may depend on exactly which subtype of PPAR is activated. I am aware of four types: PPARα, PPARβ, PPARγ, and PPARδ. Of these four, PPARγ get the most attention . . . by far."

@Mauritio
What’s interesting to me is the foods high in cysteine are high Pufa foods:https://veganalyze.com/foods_high_in_cystine_sources_list.html
So another win for avoiding the Pufas.

Haa anybody tried sodium selenite and selenomethionine and can compare them ?
According to the study I posted sodium selenite should be quite a bit more effective than selenomethionine.
Dare to think.

How about a Brazil nut. 1.2g PUFA but 90mcg of selenium elemental.

@Ecstatic_Hamster I think it's mostly selenomethionine.

*) Forms of sélénium
The forms of selenium exist in 3 major forms:- Yeast
- Sodium (selenite or selenate)
- Amine acid (Selenio-Methionine or Cysteine).
Selenate or seleno-methionine (SM) are generally found on the market. Specialists classify the Se in two main categories: organic and inorganic. The inorganic salts would be supposed to be less well absorbed by the tissues. If we only refer to SM and Selenate, this is not really true, as several studies have shown it. (4)
*) Biodisponibility
The degree of absorption of selenite is less, but sufficient, of the order of +/ 50 to 60 % against 75 % for selenomethionine. (2)
What form is the best?
Selenium in any form whatsoever, that it comes from food or supplements, organic or inorganic, is used by the body for the synthesis of selenoproteins after being first metabolized in hydrogen selene, selenium cellular storage. The surplus of selenium is converted into methylated metabolites and excreted by urine and breath. Excessive accumulation of hydrogen selenial can cause its oxidation, resulting in the production of reactive oxygen species (ROS) resulting in oxidative toxic effects in the body. (o)
All forms of selenium are well absorbed, but the absorption of selenomethionine is the best. They use the same active transport mechanism as for methionine, one of the 9 essential amino acids which can only be obtained by food, which increases the effectiveness of absorption of selenomethionine compared to the inorganic forms of the selenium.
*) Recommended Daily Supply
Currently recommended nutritional supply (RDA) in adults is 55 micrograms/day. - Daily needs are 55 mcg (AJR). 1 mcg /kg of weight is optimal.
- Diet (1) provides around 50 % of needs if you eat meat or legumes. A single nut from Brazil / Amazon covers needs (…).
- In the event of pathology / detox, 200 - 300 mcg can be prescribed punctually.
- “Too Much of A Good Thing is Bad!”
=> Selenium supplementation should not be taken every day (half-life). Except in particular cases, in the event of a detox for example, therefore punctually (2 to 300 mcg per day, in detox cure). But in this case, a contribution of curcumin would be desirable to reduce hepatic toxicity due to the impact on dehydrogenase enzymes. - Taking different forms of selenium is interesting, especially in the event of cancer prevention (recurrence).
- If you exceed +/ 100 mcg/ L in the blood serum, you impact the operation of certain dehydrogenase enzymes, especially required in the Krebs cycle.
