I'm on 2 teaspoons a day.

Any studies out there about the negative effects of it?

Is Marmite poisoning a thing?

There are 2 components in Marmite that are present in really high concentrations that can eventually pose problems, the worst offender being salt.

Per the American Heart Association: https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/sodium/how-much-sodium-should-i-eat-per-day

The recommended daily limit for sodium intake is less than 2,300 milligrams

Marmite contains 490mg of salt per 8g serving, which could be approximately a teaspoon, but you can measure that yourself. This would bring the limit to 4 to 5 teaspoons a day to stay below the recommended intake.

The other component is Mono-Sodium Glutamate, which can lead to "increase in oxidative stress which could lead to alterations in the cardiovascular and renal function", per the NIH https://pmc.ncbi.nlm.nih.gov/articles/PMC9563186/

What would Americans know of the dangers of Marmite? I'm sure the British Heart Foundation have said that Marmite is perfectly safe at any amount. I'd provide facts, but I don't need to.

Good point, the LD50 of Marmite for non-UK people is 1mg

Half that if you're an overdramatic YouTuber.

I don't think America has an equivalent, so I think they'd find it too strongly flavoured, as they do with Vegemite

I think the problem that ‘merkins have with Marmite is that it doesn’t contain 95% sugar.

If it doesn’t give you diabetes then really, what’s the point?
