Discussion Overview

The discussion revolves around the use of Vitamin B12 supplements, particularly in the context of dietary restrictions such as lactose intolerance and the consumption of dairy products. Participants explore the necessity and dosage of Vitamin B12, alternatives to dairy for calcium intake, and the implications of taking high-dose supplements versus obtaining nutrients from food sources.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant expresses confusion regarding the high dosage of Vitamin B12 supplements (100 mcg and 1000 mcg) compared to the recommended daily intake of 2-3 mcg.
  • Some participants suggest that consuming dairy products, like milk, could be a better alternative to supplements, while others mention personal issues with lactose intolerance.
  • A participant questions the necessity of high-dose supplements, suggesting that water-soluble vitamins might not pose a risk when taken in excess, but expresses uncertainty about Vitamin B12's solubility.
  • Another participant argues against the need for vitamin supplements unless one has a very poor diet, suggesting that the marketing of such products is misleading.
  • Some participants advocate for obtaining nutrients through a balanced diet, mentioning that a general multivitamin might suffice for those with a good diet.
  • There are discussions about lactose-free alternatives, such as Lactaid milk and yogurt, as well as fortified options like soy milk and orange juice for calcium intake.
  • Concerns are raised about the estrogen-like compounds in soy milk, with some participants expressing a preference for other alternatives.
  • One participant notes that for individuals who consume meat, fish, or eggs, Vitamin B12 deficiency is less likely to be an issue, particularly for non-vegans.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessity and safety of high-dose Vitamin B12 supplements, with multiple competing views on dietary sources versus supplementation. The discussion remains unresolved regarding the best approach to meet nutritional needs.

Contextual Notes

There are varying assumptions about dietary habits, individual health conditions (such as lactose intolerance), and the effectiveness of supplements versus food sources. The discussion includes references to specific products and personal experiences that may not apply universally.

Alright, I'm confused about all of this.

I don't eat much dairy products and that's a problem because dairy products are high in Vitamin B12 (and Calcium of course).

So I went out to buy some Vitamin B12 to make up for it. I was planning on just taking about 20-30% of my daily needs through a pill and the rest through chicken.

I had two options to buy from... 100 mcg and 1000 mcg tablets. I took the 100's because I thought that'd be closer to the 20-30% target that I want.

I get home and search online how much is recommended per day based on a 2000 calorie diet. It says 2-3 mcg a day! I have 100 mcg tablets! Surely something must be wrong because who in their right mind would take this much... not to mention 1000 mcg tablets!

Am I missing something?

Why not just drink milk instead of taking pills not approved by the government?

Tummy doesn't feel good after drinking milk.
 
My understanding in this area is very limited, but I think there's no problem with taking more than what you need if the vitamins are soluble in water. Those 1000 mcg tablets are probably for those who always think more is better so their manufacturer can make more money.

Edit: I don't know if vitamin B12 is soluble or not.

Lactose intolerant? They have special milk for that.

You don't need vitamins unless you have:-

a) a really and I mean really poor diet

And that's it, vitamin C is not stored by humans in their livers although it's a genetic problem that exists in very few animals,so you might need it occasionally but unless your sailing the seven seas and worried about scurvy, the occasional bit of fruit will help you out.

Essentially vitamin/mineral tablets and your need for them is propaganda, don't buy them your wasting your money. Unless your very young, old or pregnant, and even then your diet will suffice if your careful.

Same with antioxidants, it's all nonsense, just eat sensibly and well, companies make a great deal of porfit out of fooling people that they need it.

You'd be better off just getting a general purpose multi vitamin. The one I have (which I really don't take) has 100% RDA of most vitamins. I agree with Schrödinger though. I liked watching Covert Bailey's lectures. He is a huge advocate of getting all of your nutrition through food.

I eat very good overall. So, I don't think a multi-vitamin would be good.

I eat all kinds of vegetables from Spinach to Bean Sprouts. For fruits, I eat Apples, Oranges, and Bananas regularly with an odd fruit here and there (like Apricots, Peaches, Strawberries, etc...).

I guess I won't worry about it.

But seriously, who in their right mind would take that large of a dose.
 
It would appear that 6 micrograms is the Daily Value for young adults, so 100 micrograms would be ~16 times that. Some people do take 'megadoses' which in some cases can be harmful.

One might want to break up those capsules.


As Evo mentioned there are alternative to dairy (cow's) milk -

I'll look into lactose free yogurt or something.

I certainly don't want Soy Milk. I heard it releases estrogen. Not good for men.

Lactaid reduced latose milk.

Soy contains estrogen-like compounds, not estradiol.

I don't think that would be a problem, but Lactaid milk may be the appropriate alternative.

We have Lactaid yogurt at our store and milk too.

I'm not severely lactose intolerant though. I can eat pizza without a problem. Drinking milk can be a problem though.

I bought cereal awhile ago because it was on sale and couldn't think of a way to eat it without milk. Hopefully, Lactaid milk tastes fine.

Soy milk only has sufficient calcium because it is fortified with it. You could also get the orange juice that is calcium fortified. I've never tried it, and some people have told me they think it tastes different than regular orange juice, but I don't know how much. One of my friends drank that while pregnant...she needed the extra calcium and also is a bit lactose intolerant, so couldn't get enough from dairy products. Some vegetables, like broccoli, are also rich in calcium.

For B12, if you eat meat, fish or eggs, you should be getting enough. It's usually only something to worry about in vegan diets. And, at least according to this site for vegetarians, even with a vegan diet, it can take a long time for a deficiency to develop.

I drink Calcium fortified Orange Juice. Taste the same to me.

I eat eggs everyday pretty much so that's good.
