--- title: "LiveGood E3: Caffeine, Timing & Who Should Skip It" description: How to take E3, how much caffeine is in a scoop, the beta alanine tingle, and who should skip it or check with a doctor first. url: "https://coachluke.com/docs/livegood-e3-caffeine-timing-who-should-skip-it/" updated: "2026-09-24" category: "LiveGood: Fitness & Recovery" --- # LiveGood E3: Caffeine, Timing & Who Should Skip It Quick reference for [LiveGood E3](https://coachluke.com/livegood-e3/). The full review covers the complete label and the evidence in depth. ## How do I take it? One scoop in water. LiveGood says it's best early in the day and before exercise, about 20 to 30 minutes ahead. Each tub holds 30 scoops. ## How much caffeine is in it? 125 mg per scoop from organic tea, about a cup of coffee, paired with L-theanine for smoother focus. Count it toward your daily caffeine, use it in place of a coffee rather than on top of one, and keep it at least six hours away from bedtime. ## What's in it? Energy (caffeine, L-theanine, B6, B12, betaine), endurance (1.6 g beta alanine, 1 g beet root, 3 g of all nine essential amino acids), electrolytes (225 mg sodium, 225 mg potassium, 50 mg magnesium), and focus ingredients (L-tyrosine, alpha-GPC, Huperzine A, and the BetaPrime adaptogen blend). It's sweetened with stevia and is vegan, gluten free, and keto friendly. ## Why does my skin tingle? That's the beta alanine. A harmless tingling on your skin in the first sessions is normal and usually fades with regular use. ## Can I take it with LEAN? E3 has 800 mcg of chromium per scoop, and [LEAN](https://coachluke.com/livegood-lean/) adds more. That's fine for most healthy adults, but mention it to your doctor if you take blood sugar medication. ## Who should skip it? Skip it if you're pregnant or nursing, avoiding caffeine, or sensitive to stimulants, and talk with your doctor first if you take any medication. ## What if it doesn't work for me?
