Take BCAAs before training, and keep taking them through the days around a hard session, not only after it. In a 2018 trial of 15 young men on 9.6 g of BCAAs a day, the dose taken before exercise cut soreness and muscle damage markers more than the same dose taken after, and a 2024 meta-analysis of 18 studies linked longer use leading into the session to better results. The limit: BCAAs ease soreness, but strength comes back no faster, and complete protein still does the building.
US searches for “bcaa” averaged about 44,700 a month this summer, up 26% on the spring, and the searches that land on this page all ask one thing in different words: when. Here is the schedule the studies support.
The Short Version
- Before beat after: 15 young men on 9.6 g of BCAAs a day had less soreness and lower damage markers when the dose came before exercise rather than after (Journal of Sports Medicine and Physical Fitness, 2018).
- Dose and lead time count: across 18 studies, higher daily doses went with bigger drops in soreness, and longer use before the hard session with bigger drops in a muscle damage marker (Sports Medicine Open, 2024).
- Soreness, not strength: in 25 studies with 479 people, BCAAs lowered soreness at 24 and 48 hours and damage markers at 48 hours, but muscle performance recovered no faster (Applied Physiology, Nutrition, and Metabolism, 2021).
- Ninja Recovery holds 5000 mg of BCAAs (2:1:1) a scoop, inside a full set of nine essential amino acids, 7.5 g in total.
Should You Take BCAAs Before or After a Workout?
Before. In the 2018 trial, a small pilot study, 15 young men took 9.6 g of BCAAs a day, with repeated doses in the days around a hard arm workout; the group that got the dose before exercise had less soreness, better arm movement and lower muscle damage markers than placebo, and the group that got it after saw weaker effects. In a 2010 study, 12 untrained women took 100 mg of BCAAs per kg of body weight before seven sets of 20 squats and were less sore on days two and three than on a placebo.
A 2021 review of ten trials put it plainly: BCAAs “should not be administered only after” the hard session. Think of them as the South Beach lifeguard: useful in the tower before the swimmers arrive, not much help sprinting down the sand after the fact.
| When | What the research shows | The verdict |
|---|---|---|
| Before training | Less soreness and lower damage markers than taking it after (2018); less soreness after squats (2010) | The main slot |
| The days before and after a hard session | Longer use before the session could be more effective, a 2024 meta-analysis concluded | Worth it in heavy weeks |
| During training | Little direct research on timing it mid-session | Fine for long sessions; convenience |
| After training only | Weaker effects (2018); a 2021 review advises against relying on it alone | Add a before dose |
| Before a fasted session | BCAAs alone cannot supply the other six essential amino acids (2017 review) | Take a full EAA formula instead |
If you remember one line: BCAAs before the session, and in heavy weeks, every day around it.
Should You Take BCAAs on Rest Days Too?
In a heavy training week, yes, because the research points to days of use, not one well-timed drink. In the 2024 meta-analysis, higher daily doses were linked to bigger drops in soreness, and higher total doses and longer supplementation to bigger drops in the damage marker creatine kinase; the authors concluded that a longer run-in before the hard session could help both. The 2018 trial dosed for three days before and three days after the workout day.
On a rest day the clock barely matters: take your scoop with breakfast or between meals, and keep the day’s protein spread every 3 to 4 hours, as the ISSN advises. The schedule in the Fuel Plan below lays it out.
How Much BCAA Should You Take?
The two trials above used about 8 to 10 g a day: 9.6 g in the 2018 trial, and 100 mg per kg in the 2010 study, which is 8 g for an 80 kg lifter. The 2021 review of ten trials found the clearest benefit in trained people, at doses up to 255 mg per kg a day, after mild to moderate muscle damage, and a separate 2021 meta-analysis of 25 studies reported a dose response for soreness and damage markers.
For scale, one scoop of Ninja Recovery holds 5000 mg of BCAAs in a 2:1:1 split, which is 2.5 g of leucine, plus the other six essential amino acids. That is about half the daily amount those two trials used, so read the scoop as the amino base of your day, with your meals doing the rest.
Should You Take BCAAs Before Fasted Training?
Take a full EAA formula instead. In a fasted state, BCAAs on their own leave muscle short of the other six essential amino acids, and a 2017 review by Robert Wolfe (who declares industry ties) argued the only source left is your own muscle breaking down, capping any rise in muscle building at about 30% in theory.
A scoop that carries all nine covers that gap, which is why our guide to when to take EAAs covers the empty-stomach session in detail. Mix it in 8 to 10 oz of water as the product page directs, drink it on the way in, and eat a protein breakfast after.
Do BCAAs Work If You Already Eat Enough Protein?
For soreness, a little; for muscle growth, your protein intake does the heavy lifting. The 2021 meta-analysis of 25 studies found BCAAs lowered soreness at 24 and 48 hours, but muscle performance recovered no faster than on placebo. And muscle building needs all nine essential amino acids, which a protein meal brings and a BCAA-only drink does not.
The ISSN’s target is 1.4 to 2.0 g of protein per kg of body weight a day for most people who train. Hit that first. For the full head-to-head, read BCAA vs EAA: which one you actually need.
Coach’s Corner: The Fasted Sunrise Session, Scoop First
- Scoop on the way in: one scoop in 8 to 10 oz of water before the warm-up.
- Warm-up: 5 minutes easy on the rower, then 10 hip hinges with your hands on your hips. Push the hips back, keep the spine long.
- Kettlebell swing: 5 x 15, rest 45 seconds. Hinge, do not squat; the hips snap the bell up, the arms only guide it.
- Rower intervals: 6 x 1 minute hard, 1 minute easy. Legs, then hips, then arms on every stroke.
- Goblet reverse lunge: 3 x 8 a side, rest 60 seconds. Step back long, front knee over the middle of the foot, torso tall.
- Farmer’s carry: 4 x 30 m, rest 60 seconds. Shoulders down, ribs stacked over hips, short quick steps. Then a protein breakfast within 2 hours.
Healthy adults: if you have an injury, pain, a heart condition, or you are new to training, check with your doctor before you start. Stop if it hurts.

Where Ninja Recovery Fits
If BCAAs work best before the session and the full set works best for fasted mornings, one scoop should cover both. Ninja Recovery does: 5000 mg of BCAAs in the 2:1:1 split, with 2.5 g of leucine, plus the other six essential amino acids for 7.5 g of EAAs a scoop. Add 70 mg of sodium, 29 mg of magnesium and no caffeine on the label, and it suits a sunrise session as well as a late one.
Who it’s for: lifters who want their BCAAs before training, the full EAA set for fasted mornings and a little hydration, in one tub. Who it’s not for: anyone who wants a meal or a protein shake; at 7.5 g of amino acids it is the top-up, not the plate.

Frequently Asked Questions
What are BCAAs?
BCAAs, or branched-chain amino acids, are three of the nine essential amino acids: leucine, isoleucine and valine. Your body cannot make them, so they come from food or supplements. Ninja Recovery uses a 2:1:1 split: two parts leucine to one each of isoleucine and valine.
When should I take BCAA powder?
Before training: mix one scoop in water and drink it on the way into the session. In a 2018 trial, BCAAs taken before exercise beat the same dose taken after for soreness, and a 2024 meta-analysis linked longer use leading into hard sessions to better results.
Is BCAA better than creatine?
No, they do different jobs, and creatine has the stronger performance record. The ISSN’s creatine position stand says studies have consistently shown it improves high-intensity exercise performance and leads to greater training adaptations. The best case for BCAAs is less soreness after hard sessions.
Can I take BCAAs at night?
You can, and Ninja Recovery has no caffeine on its label. But the soreness research supports taking BCAAs before training, so if you lift in the evening, that is your window. On rest days, any time with a meal works.
Should I drink BCAAs during my workout?
It is fine for long sessions, but there is little direct research on timing BCAAs mid-session. The stronger evidence is for a dose before training. If you sip through the workout, start before the first set.
