Vitamins that may cause toxicity if ingested in too large amounts are:

1.vitamin A,vitamin C, and thiamin
2.vitamin C, riboflavin, and thiamin
3.vitamin A,vitamin D,and pyridoxin(B6)
4.vitamin D,vitamin C, and B12

Doesn't vitamin A,vitamin D, and
pyridoxin(B6) cause toxicity if ingested in too large amounts?

My roommate says I am wrong.
She says vitamin D, vitamin C,and B12,
can cause toxicity if ingested in too
large amounts.

I say the correct answer is (C)
My roommate says its (D)
Which of us are correct?

Tell your roomate not to worry about Vitamin C. It has been shown to be toxic to cancer cells, which is a nice thing. Vitamin A, D, and B6 can be toxic in large amounts.

I think the correct is C.
I am pretty sure that vitamin A and vitamin D can cause greater toxicity than all the other vitamins if ingested in too large amount,but doesn't pyridoxin decrease the toxicity of the vitamin A and vitamin D in (C) if it's taken together?

Pauline is correct in that point. One toxic substance does reduce the toxicity of Vitamin A. I don't think the question was infering they are taken together.
Only mega vitamin users should be concerned with this. Normals like most folks wont come close to this level.

yep. a, d, and b6.

I just took a quiz with this exact same question and the answer is Vitamin A, Vitamin D, and B6.

I apologize for the confusion in my previous response. You and your roommate are both partially correct. The correct answer is (C) vitamin A, vitamin D, and pyridoxine (B6) can cause toxicity if ingested in too large amounts.

Vitamin A and vitamin D can indeed cause toxicity if taken in excessive amounts. Pyridoxine (B6) has not been shown to directly decrease the toxicity of vitamin A and vitamin D when taken together, but it can play a role in their metabolism.

Vitamin C and vitamin B12 generally do not cause toxicity when ingested in large amounts. However, it is still important to consume vitamins in appropriate doses as recommended by healthcare professionals. Excessive intake of any vitamin can have negative health effects.

You are correct, the correct answer is (C) - vitamin A, vitamin D, and pyridoxin (B6) can cause toxicity if ingested in too large amounts. Vitamin C, riboflavin (B2), and thiamin (B1) do not typically cause toxicity even in large amounts. While vitamin C, vitamin D, and B12 can have adverse effects if ingested in excessive amounts, they are not as likely to cause toxicity compared to vitamin A, vitamin D, and pyridoxin (B6).

As for the part about pyridoxin (B6) decreasing the toxicity of vitamin A and vitamin D, it is important to note that vitamins can interact with each other in complex ways, and the toxicity of one vitamin can sometimes be influenced or mitigated by another. However, in general, ingesting large amounts of any vitamin can still lead to toxicity, even if they are taken together.

It's important to always follow recommended daily allowances and consult with a healthcare professional before taking high-dose vitamin supplements, as excessive intake of certain vitamins can have harmful effects on the body.
