Four tocopherols, from sunflower.
Vitamin E is four tocopherols and four tocotrienols.1 PUFA Protect holds the four tocopherols: d-alpha 335 mg (827 IU), d-gamma 27.17 mg, d-delta 9.42 mg and d-beta 3.88 mg. Natural d- forms, sunflower-sourced, no soy, in a liquid-filled vegetarian capsule.
Read any vitamin E label for three things:
- Gamma named on the label, not alpha alone.
- d- (natural), not dl- (synthetic).
- A source you can trace.
The companion
Vitamin C works where E cannot.
Vitamin C works in the watery part of the cell and vitamin E in the fat membrane, and C can donate an electron to regenerate an oxidized E.16 Vitamin C with Polyphenols is 800 mg of ascorbic acid with 80 mg of grape and berry polyphenols.

Food comes first: nuts, seeds, leafy greens, avocado. See your own markers in The Lab Atlas, and read the whole case in the vitamin E deep dive.
Why the form matters
The big trials tested one fraction. Then the whole vitamin took the blame.
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,2 and the suppression appears across a range of alpha doses.3 Gamma has its own work: in lab and animal studies, gamma-enriched tocopherols were more anti-inflammatory than alpha alone.4
Now read the headlines. The trials behind them gave synthetic alpha-tocopherol alone, 400 IU a day or more, for a year or longer: a 19-trial meta-analysis linked that to higher all-cause mortality,6 and SELECT found higher prostate-cancer incidence on it (HR 1.17).7 The review of the lab work says why: those trials used only alpha-tocopherol, one fraction of an eight-part vitamin.4 Read the form before the headline.
Below the line
Most people fall short.
In 26,282 US adults, 84 percent ate less vitamin E than the estimated average requirement.8 A review of 132 studies found most populations below the recommended intake.9
The blood number is not a clean answer. Serum alpha-tocopherol rides on blood lipids, so it reflects lipid load, not tissue vitamin E,10 and a review of 31 Asian studies stressed that plasma alpha-tocopherol has no validated cutoffs.11
What it does
Fats, immune response, skin, hormones.
Polyunsaturated fats. Vitamin E donates an electron to lipid peroxyl radicals and halts the chain reaction of lipid peroxidation. The requirement rises with the polyunsaturated fat you eat.12
Immune response. In 88 healthy older adults, 200 mg a day for 235 days gave the strongest skin-test and hepatitis B antibody response, more than the lower or higher doses tested.13
Skin and hormones. In healthy volunteers, 25 mg of carotenoids a day for 12 weeks, alone or with 335 mg of vitamin E, significantly reduced skin reddening from a solar simulator.14 In 1,455 US men, higher intake of zinc, calcium, vitamin C and vitamin E went with less disruption to testosterone and estradiol from endocrine-disrupting chemicals.15

Mixed tocopherols from sunflower. 83 cents a capsule.
HOLISTICLOVEpaste at checkoutVitamin E is eight molecules: four tocopherols and four tocotrienols. In one trial, 1,200 IU of alpha-tocopherol a day pushed plasma gamma-tocopherol down to 30 to 50 percent of baseline within eight weeks, and a review notes that the large human trials used only alpha-tocopherol. The product on this page is four 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.
Vitamin E: the common questions
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?
In one trial, 1,200 IU of alpha-tocopherol a day pushed plasma gamma-tocopherol down to 30 to 50 percent of baseline within eight weeks, and in lab and animal studies gamma-enriched tocopherols were more anti-inflammatory than alpha alone. A review notes that the large human trials used only alpha-tocopherol. A mixed formula keeps all four tocopherols in the capsule.
Is a high alpha-tocopherol dose safe?
The harm signals in the research come from 400 IU a day or more, taken for a year or longer, and from 400 IU a day of synthetic vitamin E in SELECT. One capsule of this product is 335 mg of d-alpha-tocopherol (827 IU as printed on the label) with the other tocopherols, and the immune-response trial peaked at 200 mg a day, with more not better. 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 more polyunsaturated fat you eat, the more vitamin E you need. The blood number rides on blood lipids, so it cannot settle the question alone. Measure it, fix the plate with the Diet Builder, and fill the gap.
