CELL FOUNDATIONS

Eight molecules. They sell you one.

The one that failed the trials. The form is the entire point.

Most of the world eats less vitamin E than it needs, the blood test cannot agree on a cutoff, and the cheap fraction on the shelf pushes the rest of the family out of your blood. Here is the form we chose, and every study behind it.

The science below is about vitamin E and its forms. The product above is a label. We keep them in separate sentences on purpose; every claim links to the study it came from.

Almost everyone is under the line. Nobody is measuring it.

In 26,282 US adults, 84 percent ate less vitamin E than the estimated average requirement.[1] A systematic review of 132 studies found most populations under the recommendation and 13 percent of blood readings below the threshold where function starts to fail.[2] A childhood review puts the highest deficiency prevalence in North America and Brazil.[3] Asian surveys report up to 67 to 80 percent in some groups, and the same review says the blood test has no validated cutoff.[4] The reason: serum vitamin E rides on your lipoproteins, so the number tracks your cholesterol, not your tissues.[5] A test nobody trusts becomes a test nobody orders, and a shortfall this common goes unmeasured.

The form is the entire point

The trials that "failed" used the cheap fraction, alone.

Vitamin E is eight molecules, four tocopherols and four tocotrienols, and the assumption that alpha-tocopherol alone is vitamin E is one the nomenclature literature now rejects.[4] In eight adults given 1,200 IU of alpha-tocopherol a day, plasma gamma-tocopherol fell to 30 to 50 percent of baseline in eight weeks,[1] and the suppression shows up across the whole range of alpha doses.[2] Gamma is where much of the anti-inflammatory activity lives.[3] Now read what the famous trials used: a meta-analysis of 84 trials found no cardiovascular benefit,[5] a 19-trial meta-analysis linked 400 IU a day or more for a year or longer with higher all-cause mortality,[6] and SELECT found 17 percent more prostate cancer on 400 IU of synthetic vitamin E.[7] Synthetic. Alpha. Alone. That is the form on most shelves, and it is the form that failed. A randomized trial in type 2 diabetes tested alpha against gamma-rich mixed tocopherols for exactly this reason.[8] We ship those harm trials on this page because they are the argument: keep the family together, in the natural d- forms, at a dose the human data supports.

What it does when it is actually there

Every membrane you own

It donates an electron to the lipid peroxyl radical and breaks the chain reaction in the fatty membrane of the cell. The requirement rises with every gram of polyunsaturated fat you eat.[1]

Immune response, heart, hormones

200 mg a day gave older adults the strongest skin-test and vaccine antibody response, more than the higher dose.[2] In confirmed coronary disease, 400 to 800 IU meant fewer non-fatal heart attacks.[4] Higher intake tracked with less testosterone disruption from phthalates in 1,455 US men.[5]

The internal sunscreen

With the plant pigments from vegetables, 335 mg of vitamin E for 12 weeks significantly reduced skin reddening from a solar simulator in healthy volunteers.[3] Nutrients, not lotion. And the crops that carry it lost minerals between 1950 and 1999,[6] which is why a careful eater can still read low.

Supplements fill the gap. Food is the foundation.

Nuts, seeds, the germ of grains, leafy greens and the oils pressed from them carry vitamin E, and they lost minerals for seventy years. Pull up any marker on your own bloodwork in the free Lab Library and see the foods the research shows move it, then let the Diet Builder turn a gap into a grocery list.

Stop buying the fraction and calling it the vitamin.

You have seen the receipts: who is low, why the test misses it, which form the trials used, and what the whole family does when it is actually present. The next move is the form that keeps the family together, at a dose the human data supports.

Vitamin E is eight molecules, and most supplements contain one, synthetic alpha-tocopherol, the form used in the trials that showed no benefit or harm. Alpha alone pushes gamma-tocopherol down to 30 to 50 percent of baseline. The product on this page is mixed natural tocopherols from sunflower oil: d-alpha with beta, gamma and delta, no soy, in a liquid-filled capsule. Every claim on the page links to a study; the product is named separately from the science.

FAQ

What is in PUFA Protect?

Per capsule, 335 milligrams of d-alpha-tocopherol (827 IU) plus mixed tocopherols: d-beta 3.88 mg, d-gamma 27.17 mg and d-delta 9.42 mg, sourced from sunflower oil in a vegetarian liquid-filled capsule. It contains tocopherols, not tocotrienols. Label as read on the manufacturer's site.

Why mixed tocopherols instead of alpha-tocopherol alone?

Because alpha alone lowers gamma-tocopherol in the blood to 30 to 50 percent of baseline, and gamma carries much of vitamin E's anti-inflammatory activity. The large trials that found no benefit or harm used synthetic alpha alone. Mixed natural tocopherols keep the family together.

Is a high alpha-tocopherol dose safe?

The harm signals in the literature come from 400 IU or more of synthetic alpha-tocopherol taken alone for a year or longer. Mixed natural tocopherols do not carry that signal in the published trials, and they also do not yet have trials of the same size. Dose to the human data, measure your status, and raise vitamin E when you raise polyunsaturated fat intake. Education only, not medical advice.

Do I need vitamin E if I eat well?

Most populations eat less than recommended, and the crops that carry vitamin E lost minerals across the twentieth century while refined seed oils raised the requirement. A careful eater can still read low. Measure it, fix the plate with the Diet Builder, and fill the gap.
