NP Omega-3 & Vit. E
Hi i am just wondering why the NP Omega-3 (Bulk) doesn't contain vitamin E in it, isn't it used in fish oil, to avoid fat oxidation and for better quality??? Other companies do put vit.E in, some have really high doses.
I also woudn't like to Overdose on vit E, since i am currently eating 40 pills/day, thats right... I MEGADOSE the NP omega!!
But still, why aren't there any vit. E in it? Lets say u could have 1-2% of the D.V in each one?? Or maybe the pills are so fresh u won't need some. Just asking.

it's just a bulk product. many of np's bulks need to be paired or used in conjunction with other supplements to elict the optimal benefit.
however, if you are taking a daily multi-vitamin you should be covered on vit e.
now adam for instance delivers 670% of the daily recommended allowance of vitamin e.

from my understanding fish oil can cause oxidative stress on the body after consumption. this is why it is often paired with vitamin e (anti-oxidant).
vitamin e should have little impact on the storage/longevity of fish oil in capsule form.
Fish oil and vitamin E go together
BELTSVILLE, MARYLAND. Fish oils are beneficial in the prevention of cancer and cardiovascular disease. They do, however, oxidize very easily and therefore add to the oxidant stress on the body. An experiment was recently carried out by the U.S. Department of Agriculture to see if an increased intake of vitamin E could counteract this detrimental effect of fish oils. Forty men aged 32 to 44 were involved. The men consumed a controlled diet for a total of 28 weeks. For the first 10 weeks they received placebo oil capsules (15 g/day), for the next 10 weeks they received fish oil capsules (15 g/day), and for the last 8 weeks they received the fish oil plus 200 mg of vitamin E (all-rac-alpha-tocopherol). The urinary excretion of peroxidation products (malondialdehyde) more than doubled when the fish oil capsules were introduced but then dropped by a factor of four when vitamin E was added. The vitamin E concentration in the red blood cells dropped very significantly when fish oil was ingested but more than recovered with the vitamin E supplement. It is concluded that the negative effects of fish oil consumption can be overcome by taking them together with vitamin E.

Fish oil supplements increase requirements for Vitamin E
LONDON, ENGLAND. A recent experiment carried out at King's College in London showed that daily intake of fish oil supplement reduces the plasma concentration of vitamin E to below normal range. Nine healthy male subjects were given a daily fish oil supplement containing 2.1 g docosahexaenoic acid (DHA) and 0.8 g eicosapentaenoic acid (EPA) for a six week period. The proportion of DHA and EPA in the blood increased during the trial while the concentration of very-low-density-lipoprotein-cholesterol and triacylglycerol decreased. Blood pressure fell slightly during treatment, but rose again once the fish oil supplementation was discontinued. Of particular interest was the finding that alpha-tocopherol (vitamin E) concentration in the blood fell from 20 micromol/l to about 10 micromol/l during the experiment. This raises the question whether fish oil supplementation increases the need for antioxidant supplementation.

I was wondering this as well, since i was under the impression that fish oil went rancid much quicker w/out vit. E. I actually ended up throwing out a bottle and half of nutra's fish oil because i believed it to be rancid. I remember when i received the package it was summer and everything in the box was super hot. Then within a couple weeks of taking them i noticed i was getting flushed in the face much more often which i attributed to more inflammation (who knows for sure though). I switched to a different brand a week later and personally felt it made a difference but again maybe effect was in my head. Also the nutra brand smelled much worse than other brands i've used which supposedly is another sign of being rancid. Love Nutraplanet but i'm sticking w/ other brands that specialize in oils.

The softgels do not allow oxygen in, which is required for oxidation. The fish oil softgels are capped fresh, sealing in the fish oil away from oxygen - thus PHYSICALLY preserving them.

fish oil can go rancid if you don't use by the expiration date. to keep them longer you can referigerate or freeze them.
if you wonder if they are rancid, bite into one. you'll know right away if it's gone bad.
fresh fish oil will be clear, and taste mildly fishy.
rancid fish oil tastes like eating out an 80yr old whore......not that i would know.

yea...they may have been fine. I guess i was just paranoid about the package getting so hot in transit. I couldnt' bring myself to do the "bite into the softgel" test but they definately smelled worse than the many others i've tried. They are so cheap that i didn't really mind tossing them. oh well.

I've never refrigerated/frozen mine since I don't seem to get fish burps, even if I take them on an empty stomach

So back to the question about Vit. E. I just started with my canister of NP Fish Oil. Using about 10 per day. Should I be taking in some Vit. E to prevent oxidative stress? I saw the studies above, but is everyone that is using the NP brand also using Vit E too?
