FAQs
What is the difference between EAAs and BCAAs?
BCAAs are three of the nine essential amino acids: leucine, isoleucine and valine. EAA products include all nine. Each scoop of Essential Amino 9 lists 5 g of BCAAs within 7.5 g of total EAAs. The Australian Institute of Sport places BCAA supplements in Group C, meaning the evidence does not support a benefit for athletes.
Does it contain caffeine?
No. There are no stimulants or added sugars on the panel, and Rule 1 notes it can be used day or night. If you want caffeine before training, you would need a separate pre-workout and should check the combined label totals.
Can I use it on rest days?
Yes. Rule 1 suggests taking it around workouts on training days, and any time on non-training days for extra amino acids and hydration support. One scoop is the label serve.
How many serves are in a tub?
Each tub has 30 serves of about 11.5 g. Rule 1 lists the same amino acid amounts across its flavours, though small differences between flavours are possible. Compare other options in our EAA range.
