Pumkin seed oil inhibits 5ar and simultaniously increases testosterone, so what do we take beta sis. for?

pancacke - Very good question. When it comes down to it, Pumpkin seed oil trumps beta sitosterol in many ways.

I have been using pumpkin seed oil daily for about a year now.

CS, in what ways is it better?

And out of curiosity in respects to dry skin how does Pumpkin seed oil compare to Borage or EPO?

I actually have been snacking on roasted pumpkin seeds which are delicious. They are higher in protein than carbs and make a great snack. I wonder if I'm getting any benefits from them.

if they were raw you would be getting good omega 6, but otherwise your just getting minerals and vitamins.

As you think beta sit is helpful for the young, would you also recommend pumpkin seed oil for the young? If it is superior, do you think people could stop hair loss along with PSO like some people have attributed their stabilising and regrowth with beta sit?

tooyoung - Stopping hair loss, I'm not sure. However, PSO does contain phytosterols, but also in its raw, organic form, it is an excellent source of Omega-6 PEO (Parental Essential Oils).

This means potent anti-inflammatory and increased oxygen transfer.

Does PSO increase SHBG like beta sitosterol does? Would there be any problems taking PSO and beta sitosterol together?

pancacke Sat May 07, 2011 12:16 am

No, there are even products that include both....

Bumping an old thread...

Would oil be preferable to just actually eating the seeds?

I know flax oil can go rancid pretty quick, what about pumpkin seed oil?

Cheers, C

well if you could get the raw seeds then it wouldn't matter most I find are roasted. If you get oil make sure it's cold pressed and has tinted bottle or way of ensuring freshness.

CS, do you recommend a certain brand? If we could find a cold pressed, raw, organic PSO with astaxanthin combo we'd be preventing oxidation efficiently. That being said, you could buy a quality brand and then add your astaxanthin separately. I'd like to give it a go in the near future, but want to avoid the seeds for optimal digestion purposes. I've got some ground to make up as I've eaten a of garbage over the past year and prior to that did a decent amount of drinking along with a less than optimal diet for around a year. The year prior to that, though, is when I got my digestion in a healthier state and saw some good results. since then it's been a rollercoaster of lack of discipline and experimentation

I've seen CS recommend flora before

Before the analysis the oil was held in darkness at 10°C for 2 weeks

Oxidation rate was followed by periodic determinations of peroxide value (PV). PV was expressed as meq O2/kg of oil. These determinations were carried out in triplicate.

In Figs. 1 and 2 is showed the effect of storage conditions on the formation of oxidation products, expressed as peroxide value (PV) versus storage time.

Storage conditions:
I - at room temperature with exposure to daylight (the samples were places approximately 2 m from window; the room temperature was 20-25°C.);
II - at room temperature in darkness;
III - at 10°C with exposure to artificial diffused light;
IV - at 10°C in darkness.

At the beginning of experiment a PV for sunflower oil was 2.09 meq O2/kg and 1.86 meq O2/kg for pumpkin oil. These values were considered as satisfactory according to the international regulations on edible oils

For pumpkin oil, after 4 months, the peroxide value reached 22.87 meq O2/kg. in the storage conditions I, 11.03 meq O2/kg in the storage conditions II and 15.06 meq O2/kg in in the storage conditions III. The PV registered for the both oils not exceeded 10 meq O2/kg in the storage conditions IV

You've got to wonder how and how long bought oils are being stored and shipped. If your oil has been sat in a factory for just 90 days at room temp, even in the dark, then PV would have over 5-fold increase (1.86 meq O2/kg to over 10 meq O2/kg - under the conditions of that study). At what level does PV become harmful?

Wouldn't make more sense just to eat the actual seed and avoid PV altogether? (a few fresh organic pumpkins would yield 1,000's of super fresh seeds) I'm leaning towards overnight-soaked seeds as my source of unadulterated PUFA

(my only concern are seed anti-nutrients though figure soaking should at least in part solve that)
