"Doubt" cast on necessity of Vit D

[austinite]

Taking any supplements unless you are deficient would be fairly useless and could cause harm!

This is as far from the truth as it gets. Sorry T, that makes zero sense whatsoever. You're basically saying that RDA is on point and perfect. lol.

Well, I am saying that taking a supplement unless there is a need would be deemed unnecessary. Now, I assume blood work would show if you are deficient. I understand that RDA might not be perfect and is an arbitrary value made up but it is something. What should one go by in your opinion?

Thanks

Yes, but we have to remember how many times RDA and 'acceptable' serum ranges have changed over the years. There is absolutely, 100% and without a doubt benefit to some vitamins/minerals in excess of these ridiculous and absurd ranges. Ranges that will likely change, yet again.

I'll copy from my Essentials Thread...

That being said, there are 3 stages of state. Malnutrition, healthy and optimum. Malnutrition is obviously a poor diet. You're just not getting enough of the essentials and that will become problematic. Supplementation should NEVER be considered in cases of self-induced malnutrition. It's your responsibility to eat right. That's your first line of defense.

Healthy state is one with a good nutritional plan. If you're happy with that, great. No need to change anything.

Finally, there's optimal. This is where supplementation comes into play. Recommended Daily Allowance (RDA) is merely enough to maintain a healthy state. These are also based on 2,000 calorie diets. They're likely to have your serum levels in range, lower range, but still in range. This range is considered healthy, or 'acceptable'. Most vitamins, minerals, herbs and amino acids are ok when these ranges are exceeded. In fact, you'd amplify the benefits in many cases. That stage would be considered optimum.

austinite,

What concerns me here is the term optimal and by that I want to point out I am no way trashing your excellent writing on the matter. What is optimal is, I assume, a case by case basis? Is there also not a danger as science is proving that supplementing with Vitamin A will actually shorten lifespan (Using Vitamin A as an example) and therefore what might be considered optimal could in fact be dangerous!

Thanks

Yes, I've clearly stated (multiple times in my post) that the rule does not apply to everything. Even water and air in excess can kill you. But those are far and few between. Vitamin K for example, no need to ever use it at all unless you have clotting issues.

We can't generalize and say "Nothing in excess of RDA/ranges is ok". That's not fair to those who really want to maximize the benefits.

I take 1000 times what most people take with Arginine. I am at 5 times over the recommended B12 serum range. Massive difference my friend. Vitamin D.... Forget about it! 600,000 IU injections, son.
