Quick answer: Going over 400 mg of caffeine in a day does not produce the same result for everyone, but the risk of unwanted effects can rise. Count caffeine from every pouch, drink, food, medicine, and supplement you use.
What does 400 mg mean?
The FDA cites 400 mg per day as an amount not generally associated with negative effects for most adults. It is a reference, not a goal or a guarantee. Body weight, medical conditions, medications, pregnancy, breastfeeding, and individual sensitivity can change what is appropriate.
How quickly can pouches add up?
LyvWel currently lists pouch strengths of 56, 72, 125, and 225 mg. Two 225 mg pouches would total 450 mg before counting any coffee or other caffeine. Check the current label because strengths and serving directions can change. Compare caffeine per unit across formats.
What signs should I notice?
Too much caffeine can cause jitters, anxiety, trouble sleeping, a fast heartbeat, palpitations, nausea, upset stomach, or headache. Stop taking more caffeine if symptoms occur. Seek medical advice for symptoms that concern you, and urgent help for severe symptoms.
Does plant-based caffeine change the limit?
No. The FDA states that the body handles naturally occurring and added caffeine the same way. Guarana describes LyvWel's source of caffeine, not a different safety threshold.
