vitamin E complex?
-
is it necessary to take the entire complex or is alpha tocopherol alone good? can it become toxic at a certain point or does it just cause an imabalance?

- can it become toxic at a certain point
- Not alone. minimum 2 tocos, 80 % alpha and 20 % another one could be ok. Alpha-toco could prevent another kind to reach the target..
- too much of a good thing is bad. Excess quinones.
Excerpt 1
“Vitamin C regenerates vitamin E and vitamin E protects β-carotene, helped in this by polyphenols. In the event of β-carotene supplementation, vitamin C regenerates vitamin E and β-carotene, and β-carotene seems to protect vitamin E without really explaining this phenomenon"
Savings effect
Vitamin E is not just a vitamin. Vitamin C makes it possible to recycle oxidized vitamin E and thus prolong its lifespan. The same goes with glutathione which is thus saved for other more useful functions (detox). Glutathion is our antioxidant master.
Vitamin E protects against the deleterious effects of polyunsaturated fatty acids when the latter are excess. And this is quickly done!Note: I can give a link if you want more details.
I take 400 UI 2x/wk. 3x if inflammation ... -

I take 400 UI 2x/wk. 3x if inflammation ...The VitE you want is tocotrienol (Delta and Gamma). The sourcing should be from the Annatto plant.
Check out Dr. Barrie Tan - the foremost expert on it. He's got plenty of long form interviews on YouTube.

Not just α-tocopherols. Why?
We shouldn’t supplement with just one form and neglect the others. Why?
Members of the vitamin E group are much more effective when combined. Different forms of vitamin E have complementary free-radical scavenger effects, not only against ROS.
Together, the different forms can combat a much broader spectrum of free radicals than alpha-tocopherol alone. To some extent, alpha tocopherol can inhibit the generation of free radicals. Gamma tocopherol, on the other hand, is able to immobilize and eliminate existing free radicals as highly toxic as nitric oxide. Gamma tocopherol can thus protect cells from the mutagenic and carcinogenic effects of very dangerous reactive molecules. (1)
Even when a high level of α-T1 saturates the carrier (> 250 UI?) there is a passive assimilation. Up to recently (2000-2010, note’s editor), it was thought α-TTP (α-tocopherol transfer protein) has the greatest binding affinity towards α-tocopherol compared to other vitamin E forms (Hosomi et al., 1997). But, even if there is well a positive discrimination at the site of the liver (via VLDL, LDL and HDL, as carriers), (showing a preference for α -T1), this is without taking into account the passive absorption of the different tissues, for the other forms of T1 and T3 (passive diffusion).
T1 = Tocopherols
T3 = Tocotrienols
α-TTP = α-tocopherol transfer protein (carrier)
