For ducks - Nutritional yeast with iron?

[Warty Frog]

So I bought this to supplement my 4 weeks old ducks diet. And today I realized that there is a bit of iron in this nutritional yeast. Does anyone know if this is ok? Thank you!!

The nutritional yeast I used has a little more iron than what yours has and my ducklings did just fine with it.
Is there a reason you are concerned about the iron?

This source references studies finding that ducks needed between 45 and 85mg per kg of body weight, so yes, that's a perfectly acceptable level of iron for a duck.

Thank you everyone for the info! So helpful. I will resume using that bottle of nutritional yeast then!!

Can you tell us what the brand of niacin is? I've never looked at the nutritional make up of the yeast I've given my ducks. From what I can see of the ingredients it looks fine. Is there a reason your concerned? If its due to "hardware disease" that's not caused from nutritional iron, but from ducks actually eating metal which cannot be digested.

Thank you for writing! The brand is NOW (also see picture). It has 0.5 mg of iron per 2 table spoon. Thank you!

That's fine. From what I found, all nutritional yeast has iron content.
