Vitamin D3 - 1,000 IU somewhat daily (depending on sun) Vitamin C - 1,000 mg somewhat daily (but wondering If need this daily?) Niacin (Vitamin B3) - 100mg somewhat daily (currently) for anxiety, mood, depression, energy
When I don't take them, my mind thinks I may be lacking in certain vitamins, or if I don't take niacin I may think that my anxiety levels will rise.
How much of a placebo effect is there in vitamins/supplements?
There is somewhat of a placebo effect, but it depends on the person. In your case, I think yours might be significant. I would expect the placebo effect on anxiety to be larger than on, say, fatigue, because anxiety is more influenced by the mind.
But here's the deal, you need to get nutrients, if you don't then your body won't work as well. If you are dependent upon supplements for them then the supplements are better than not getting them, but realistically you shouldn't need to take vitamin c or niacin because a paleo diet provides enough of those. Are you eating fruits, vegetables, and meat? Then you most likely have enough of those. Just think about people who don't take supplements and are fine. Well you're probably getting more nutrients from your diet than most of them. You're probably fine too!
But if you are having anxiety issues I would supplement with magnesium. Doesn't matter how much I get from my diet, if I supplement with a good form of magnesium like malate or glycinate I feel better. Magnesium is the king of anti-anxiety nutrients. You might also consider bone broth, it has a lot of good amino acids like glycine and arginine which are also preventative of anxiety. I would expect all of the above to assist in mood and energy as well.
I used to be the same way, but I'm pretty sure that I get enough nutrients from food, and nutrients are probably better obtained from food, with some exceptions like magnesium. If you truly think that the supplements help then by all means take them, I just don't think that vitamin supplements are necessary for most people. Maybe some minerals, some of the time, but not really those ones, except for vitamin d.
You need to up your supplements.
Vitamin D 1000 IU is low. Aim between 2500 - 5000 IU D3 type Vitamin C 1g is low. Aim for at least 1g 3 times a day, preferably more. (4x2 IMO) Niacin 100mg is OK but perhaps 500mg will do better for anxiety. You need to take flushing niacin for this effect and not sustain release which can damage liver. I would also suggest w-3 fish oil 2 tsp / day.
Stabbgy is wrong - you don't have enough C on paleo diet, or any diet. He is right that you should add Mg to your protocol. I would also advise every day cashews (4 tryptophan).
There might be placebo effect involved but its a GOOD THING. Placebo, by definition, must be the best medicine ever. Anything with property to bring placebo to you and not poison you is a good thing.
Your body might become reversibly reliant on some supplements. You should stop them gradually over time if you want to be 100% sure the body will handle it without stress, although, it wont be much harm if you stop it suddenly. For instance, stopping C suddenly can induce rebound scurvy - acute drop of immune function in subsequent few days until the body recalibrate its enzymes that depend on C.
Your question was not stupid at all. People that question you might possibly be though. If you want an answer go to Google Answers: Power of airport security x-ray machines. Category: Science>Technology. Also organicconsumers.org/Irrad/irradFAQ.rtf. Also check info by Phillip Harvey, Ph.D., chief science officer at the National Nutritional Foods Association in Newort Beach, CA.
Obviously, these highly educated people do not think it's a stupid question or a waste of time.
Or if you have no luck here just Google "will airport machines harm vitamins" and then go to "power of airport security x-ray machines".
The short answer at this point seems to be NO.
