Glycine And Libido

[Jing]

Can glycine cause low libido and poor erections? I've been taking about 5 grams of glycine before bed for past 2 weeks I think it is helping me sleep a little better but I'm finding it harder to wake up in the mornings and I've noticed my libido and erections are worse than before not sure if anything else is the problem.

Glycine is a downer or it can potentiate NMDA. Although it can upregulate 5 AR, when I take Mag Glycinate, I’m kind of blah.

Maybe your GH levels are higher. I believe glycine enhances noctural GH secretion, which means more prolactin, lipolysis, cortisol, etc.

Yeah glycine kills my libido, maybe it's due to the containments in the supplement even though I use the pure ones. Taurine even with 'other ingredients' is much better for libido and erection in general.

Dam, find something that helps in one area but causes problems in another area very annoying ..

Could be smashing your Cortisol to the floor. I've mentioned this before, we need a tiny bit of cortisol for libido.

try making your own gelatin imo, taking supplements messes you up, makes you upregulate or downregulate things we don't even know about, might as well make it natural from food

Very respectable points here.

Not a fan. But collagen is great stuff. Isolated aminos not so much.

If you live in the UK (maybe the USA or rest of Europe too?) a Vietnamese chain restaurant called "Pho" do variations of a bone broth with meat and herbs for £7-10.

No added ***t, so it's an option once or twice a week (if you enjoy it) to save messing around creating your own.

+1 to isolated aminos causing issues. Taurine and glycine / glycinate included. Anxiety plus insomnia from glycine isolates here.

What problems does it cause? Stress can stimulate the production of estrogen and testosterone, and anything that turns of the stress reactions, or downregulates ACTH, might results in reduced libido. I can't think of any mechanism by which glycine would reduce teosterone/libido in the long-term. It is one of the most basic anti stress substances

It gives me erection problems and low libido and harder to wake up in the mornings and more fatigue throughout the day.

Interesting. So, you are feeling worse overall? What product are you using?

By description, over-sedation could be a major factor. It is possible the use of fairly large amount of glycine in late evening and apart from food could do this. Every nutrient response depends on context. @ecstatichamster 's point about gelatin compared with single amino acids is also useful. You might experiment with less glycine, or take some of the amount with the evening meal, or both.

Do you take it with a meal or on an empty stomach?

I take it after a meal.

Glycine can be an inhibitory neurotransmitter after all, so yes, it can make one lethargic. That is not the same thing as saying isolated Aminos are problematic. That’s just a property of Glycine itself.
