What's it called?
As long as you're eating a balanced diet that includes some whole grains, you shouldn't need to supplement "complete proteins" as things like beans, seeds, and nuts are (typically) "half complete" and (most) whole grains are the "complementary half."
And Vitamin D you may be able to get from the sun. I forget the degree line, but if you live above that degree line in the Northern Hemisphere, then apparently no matter how much you sit out in the sun, you're not going to get enough sunlight to synthesize Vitamin D.
Sorry, I took it to mean a diet of basically
only fruits, veggies, herbs. In which case yes you would need to take a protein supplement. As for vitamin d, it's pretty much the only thing that everyone should supplement with nowadays. You would be hard pressed to find someone who is getting the
optimal dose of vitamin d everyday.
What is your experience and knowledge level on the subject if you don't mind my asking?
5 years or so spent reading various human nutrition/longevity forums and a few hundred pounds of books I've got lying around. Nothing formal though.
I can tell you though that megadosing on antioxidants is only a good idea on paper. This has been known for some time.
How much are you taking of each vitamin? And how often? What form of the nutrient do you take? Also what "antioxidants" do you take or it is just vitamins?
Vitamin c I understand. There's too much talk about asorbic acid for people not to get sucked in by it. Still, I get plenty from the multi I take.
Vitamin d is good continue to supplement 5,000 IU d3/day. Bump it up to 8,000 IU in winter if necessary.
Vitamin e shows very mixed results in the lab, with most models showing apparently little to know protection. At the very least I hope you're taking mixed pherols
and trienols.
Vitamin a, well let's just say if you're mega dosing on retinol you're asking for trouble. It must be carotene.
Vitamin b? Which one? And why?
Everything listed above can be gotten in suffiecient supply via diet. What you're proposing here is just overkill I believe and is certainly not supported by modern nutritional science.
Spirulina, well that was just the first thing I could find but I've been hearing some whispers lately you may want to look into some of the really recent stuff on it...
