This liquid tonic provides a massive 100mg dose of iron along with some B-vitamins like Thiamine and Niacin. Because it is a liquid, it can be absorbed quickly, but such a high dose can carry a risk of toxicity if not monitored closely. It is a very potent option for significant energy support.
The liquid format is helpful for those who can't swallow pills, but the taste and high iron content may be difficult for some. It is a traditional formula that has been used for a long time but lacks the modern chelated forms.
