Consensus on a good Vitamin C source?

Isn't Vitamin C not from whole food sources (ascorbic acid) problematic because it reduces copper?

LetTheRedeemed

@Alomongerpete I guess I’d eat more copper rich foods

Is Buffered Vitamin C worth taking?

Ok but the bioavailability (of most buffered vitamin C) is supposed to be somewhat less effective. But if you need a high level, like 1 g, and you suffer from acidity, it's acceptable.

See above for other details (answer to Mossy)

@Corngold lol at this point that answer is a meme on these threads

Corngold

@LetTheRedeemed lmfao yeah I think so

@LetTheRedeemed why not just acerola powder? it's 20% vitamin c,

Mind acerola when seeing 500 mg vit C in caps. Not only pure acerola, but often with additional powder. And then you're not sure of the appropriate one (without HM, the right degree 20.5 - 21.5° or the CAS reference).

@LucH said in Consensus on a good Vitamin C source?:

L-glutamine + taurine and glycine (or collagen).
1° for the stomach line
2° as antioxidant
3° as moderator (excito-toxity)

I'm curious of your opinion about Peat's dislike of glutamine. What do you think about either omitting glutamine from this combination or replacing it with an alternative that would be more Peat friendly?

@Mossy

why not threonine?? converts to glycine and is also proven to heal the gut too

Yes, glutamine in excess (when taking a supplement) could take the pathway glutamate, which is an excitatory substance for the brain. Not desired when in excess. That’s the excitatory side, which is counterproductive when the balance is not reached.
On the other way, we need glutamine as material for the border brush of the intestinal wall. That's the usual material.
We have to find a right equilibrium. Low doses and a moderator like glycine and taurine. Glycine as a gaba-like affect; taurine as an anti-oxidant and so much more – very much more for the brain.

My shake (100-120 ml water or in orange juice), this evening:
1/8 tsp taurine
¼ tsp glutamine
2/3 dose magnesium bisglycinate ( 1 dose = 2.5 g)
1 tsp collagen (glycine)
¼ tsp calcium citrate if required (if under 850 mg Ca) but not every day, of course (…). CaPh would be a better choice if ---

Edit: Glutamine powder becomes / could become only glutamate when passing through the border brush (if no used up).

Reminder:
Taurine as a neuro-protector and moderator of excitotoxicity (1)
Taurine exerts its neuroprotective functions against glutamate-induced excitotoxicity, particularly the glutamate-induced increase in intracellular calcium levels.
Taurine also serves to maintain the structural integrity of the membrane [6], to regulate calcium binding and transport [7, 8], as an osmolyte [9, 10], neuro-modulator [11], neuro-transmitter [12–18] and neuro-protective against neurotoxicity induced by L-glutamate (L-Glu) [19, 20]. Excuse for so little!

@LucH
Interesting. I appreciate the shake recipe. I assume gelatin powder or straight glycine could replace the collagen?

Mossy

@wester130 said in Consensus on a good Vitamin C source?:

threonine

Interesting, as well. Your thought is to replace the entire combination with this one amino acid?

oliveoil

I’m starting to take acerola powder along with collagen to boost collagen synthesis. Acerola powder is extremely rich in vitamin c, half a gram gives you the whole daily value.

That being said, I don’t know if it comes with any tradeoffs

LetTheRedeemed

@wester130 interesting. I don’t know about it.

wester130

@Mossy you can add it in instead of glycine

LucH

@Mossy said in Consensus on a good Vitamin C source?:

Yes, when taking 10 g glycine, you only assimilate 2 g (20 %). (Study given by Haidut)
I'd take the half dose in the shake (5 g powder).

@oliveoil said in Consensus on a good Vitamin C source?:

yes, but remind that 500 g acerola is not 500 g L-ascorbic acid. +/ 20% vit C.
And if it mentions more on the product, it's a fake (lie) or a possible "poison" (half effective vitamin C added => not recognized by the body / cell fouling).
