Vitamin E Level in Adipose Tissue Reflects Long Term Intake

This study was designed to examine the storage capacity for vitamin E in liver, adipose tissue and skeletal muscle of growing pigs during a period of supplementation and of depletion. Therefore, biopsy specimens of these tissues and samples of serum were frequently taken from 7 pigs throughout the experimental period. After a 7-week period on a diet highly supplemented with vitamin E (405 mg/kg), a significant increase (p less than 0.001) in the concentration of this vitamin was observed in all tissues sampled. The highest level (102.9 +/- 26.2 mg/kg) was observed in the liver. After 2 days of depletion the concentration of vitamin E in the liver had fallen by 80%, whereas the concentration in the fat and muscle remained unchanged during 1 week of depletion. The serum vitamin E value rose significantly (p less than 0.001) after 1 week on the supplemented diet and then remained at about 7 mg/l throughout the supplementation period and decreased (p less than 0.001) after 2 days on a nonsupplemented diet. Generally, the serum vitamin E levels among growing pigs are between 2 and 3 mg/l. The results show that the serum and liver values were correlated when the serum level was within this range. Moreover, it is clearly demonstrated that the concentrations of vitamin E in serum and liver reflect the immediate nutritional status of the animal, whereas the vitamin concentrations in adipose and skeletal muscle tissue reflect its long-term nutritional history.

It seems that the body doesn't easily deplete vitamin E from adipose tissue, even when one is losing weight. I wonder if it's to save it for real emergencies?

Burn injuries rapidly deplete vitamin E, study finds

Severe burn injuries in children have been shown to rapidly deplete the levels of vitamin E in their body's adipose, or fat tissues, a new clinical study has found. Stored levels of this important antioxidant were reduced more in a few weeks than might normally be possible in years.

If you get a sunburn, high dose vitamin E? Is that an implication? It sucks it's so hard to get good vitamin E quickly.

Conclusion: If you want vitamin E to work as an antioxidant for PUFA, you have to supplement all the time, because the vitamin E in adipose tissue only will be used in emergencies.
