Yes same. Eggshells irate my gut somehow. And Now's calcoun carbonate seems okay. I think danny roddy has spoken favorably about it too. Not saying it's perfect . But probably a lot better than not taking any. I take like 500mg per day .What calcium are you using? I am using calcium carbonate. Seems to work ok.
The powder bottle?And Now's calcoun carbonate seems okay.
Yes that's why I think the effect would have been way stronger if they included vitamin A,E,K and calcium.Nice study. Reminds me of this older one: Vitamin K And D Reverse Muscle Aging, May Act Like Sports Doping Agents
Yes I got that one ,too.The powder bottle?
I got that one.
Those test levels are so low that I'm not sure about calling them healthy. 10nmol/L = 288ng/dLIn this study they gave healthy males a dose of 4000 IU of Vitamin D and/or the flavonoid Quercetin every day for 8 weeks.
After 8 weeks the testosterone level was increased by 41% ,but only in the Vitamin D group!
Adding Quercetin to vitamin d actually completely removed any increase in T.
That shows how powerful Vitamin D is (a steroid itself) . 4000 IU isn't even a high dose . Just imagine how much better it would have been if they added Vitamin A, E, K and calcium to the mix.

Good point on the number 10 nmol.Those test levels are so low that I'm not sure about calling them healthy. 10nmol/L = 288ng/dL
The normal range (Merck) is 300-1200ng/dL (midpoint is 750), notwithstanding that some labs invent their own ranges based on the sick patients they see.Good point on the number 10 nmol.
But it would appear that it is 12nmol the starting point and 16nmol after Vitmain D in the study.
That would be 346 ng/dl to then 461ng/dl with Vit D3.
So that is much better and enters into what mainstream Testosterone values are considered good, not that anyone would wish for such low levels anyway outside the mainstream mentality.
I am well aware of it.The normal range (Merck) is 300-1200ng/dL (midpoint is 750), notwithstanding that some labs invent their own ranges based on the sick patients they see.
346ng is still bottom of the barrel, they went from low to below average.
I am not disagreeing with you. 700 is already below the average found in older studies of healthy populations. But men with 300 and even lower test were being told they were perfectly normal even 10 years ago so that aspect isn't new.I am well aware of it.
Recently at my lab they reduced the top range to around 700 for some reason.
I would not be surprised that is a tell tale they see mostly under 700ng/dl on daily basis so they made that up, of course this is pure specualtion.
What I am saying, if you go to a doctor and have 350ng/dl, 95% of the doctors will find that normal, let alone 450ng/dl.
When participants with abnormally high baseline testosterone levels were included in statistical analysis, there was only 1.7% increase in the D group (P=0.963), 2.5% in the P group (P=0.949), 0% in the Q group (P=0.998), and 3.4% in the D + Q group (P=0.849).
I do feel benefits from D, but I believe it is only able to somewhat normalize T when it is abnormally low and not further increase it. But this is still pretty impressive.
The study authors also noted:
On the other hand there are at least 3 other randomized controlled trials with vitamin D that didn't find any effect on T.
Some even found an increase in E and decrease of insulin sensitivity.
Most consistently it seems to lower SHBG. But Ray says SHBG helps androgens enter the cells, so low SHBG is not ideal.
What is the effect of carbohydrates on SHBG?But Ray says SHBG helps androgens enter the cells, so low SHBG is not ideal.
Yes I'm pretty sure it will be synergistic! It increases osteocalcin ,which increases T . There was supposed to be an idealabs osteocalcin supplement but it never happened.Nice, so this is Vitamin D by itself without k2. Wonder if adding k2 will make a difference?
what was going to be in that supplement?Yes I'm pretty sure it will be synergistic! It increases osteocalcin ,which increases T . There was supposed to be an idealabs osteocalcin supplement but it never happened.
Nice, so this is Vitamin D by itself without k2. Wonder if adding k2 will make a difference?
Osteocalcinwhat was going to be in that supplement?
k2 could negate the effects of d3, it becomes more important if using lots of d3 along with a high calcium diet, or supplementing calcium
good stuff, i was recently looking more into quercetin, not sure if that was you i discussed with how wikipedia has rutin and quercetin listed as a thiamine antagonist as wellIn this study they gave healthy males a dose of 4000 IU of Vitamin D and/or the flavonoid Quercetin every day for 8 weeks.
After 8 weeks the testosterone level was increased by 41% ,but only in the Vitamin D group!
Adding Quercetin to vitamin d actually completely removed any increase in T.

Excellent find man.
My mood and motivation improves so much with 4k IU D3 x day. Maybe it is the testo increase? Problem is... it lowers quite a lot my physical stamina and I haven't found yet why. I use also k2, mag/cal, but still...
Any ideas Mauritio?
