Best Amino Acid Supplements of 2025

"After spending over $100 on another brand, I decided to try this one. I find it just as effective, if not better, and at about half the price. Three small capsules are much easier to swallow than ten huge pills. I take them every morning, and I feel my recovery is quicker. Skipping a day makes me more sore. I love spending just up to $20 every couple of months instead of $115!"

"I’ve been taking this product every morning after my workout on an empty stomach, and I've definitely noticed how quickly my muscles recover. I highly recommend it!"

"I was astonished by the results of this product. After suffering from pain for years, I started taking these aminos and experienced relief in just about three days. I had tried everything else, including massage and acupuncture, but this is the only thing that worked. My pain is gone, I'm losing weight, and I have more energy. This has truly been a miracle for me!"

"I was initially skeptical about these due to the price, but after a few weeks, I became a fan. They effectively help bridge my protein intake gap, and I’ve noticed reduced muscle soreness after workouts. Although I don’t experience side effects, I find them a bit tricky to swallow, as they tend to stick to my mouth. Still, the amino acid content is worth it."

"As a busy mom to three little ones, I struggle to eat breakfast. I often take these tablets after my morning coffee to keep my energy up until the kids nap. They’re easy to take, have no noticeable taste, and I usually drink them quickly to avoid any lingering sensation."

"After hearing about this product on TikTok and reading many positive reviews, I decided to give it a try. The delivery was prompt, and the product arrived in great condition. While I haven't seen results just yet, it seems to effectively meet my daily protein needs."

"Honestly, it's like I have new knees and my muscle pain and fatigue is virtually gone. I can even speed walk again. I wasn't even expecting the pain relief and fluent mobility; that was a bonus! I was just told this is a great supplement for working out. Amazing stuff!"

"Initially, I was hesitant because amino acids are usually just protein, but it REALLY DOES WORK. I waited two months to write this review. As a 61-year-old woman who loves cardio, after an accident, my muscles atrophied. I started taking this and I have come back STRONGER than before the accident. I definitely feel stronger, and my muscles are returning to normal in a VERY SHORT TIME. I will definitely be ordering more!"

"I started taking this to help combat muscle fatigue. I work in hotel housekeeping with nine-hour shifts, constantly bending, lifting, pushing, and stretching. After taking a full bottle over a month, I've noticed I'm not as sore when I go home. I stopped for a few days, and the night-time soreness returned. This is the first amino acid supplement I've tried, and while I plan to explore others, this one does what I need for the price!"

"I really appreciate pure encapsulated supplements; I've had no issues so far."

"For our love life, free-form amino acids have made a big difference. My husband, at 81, takes them along with other morning supplements, and they are essential for us. We've noticed that Cialis isn't effective without these supporting nutrients. We stick to nutritional supplements, avoiding anything too risky."

"I usually take three capsules before my morning workout, and I always combine them with a protein shake because I can't handle them on an empty stomach."

"After using this product for about one and a half months, I've noticed a significant improvement in my body's recovery post strength training sessions. No side effects, just positive results!"

"I feel a positive difference in my overall well-being since I started taking these aminos."

"These have been easy to take, with no bad taste, and I appreciate the value for money."

"As an active person, I find this product works great for me. The fruit punch flavor is amazing—it reminds me of old-school Kool-Aid but even better! I've also noticed it helps with soreness and recovery, giving me a nice energy boost during my workouts. My only drawback is the inclusion of Red 40, which I wish it didn’t have!"

"I wanted a pre-workout without caffeine and something that aids in recovery. After using it twice, I was shocked at how light the weights felt. I managed to do extra sets and reps without feeling sore. Although the fruit punch flavor is not my favorite, it’s tolerable when diluted with more water. I’m excited to stock up on it!"

"I was skeptical about BCAAs, but after trying this product post-leg day, I was amazed! I usually suffer from severe DOMS, but this time my legs felt significantly better the next day. The watermelon flavor is delicious, like a Jolly Rancher, and it dissolved easily in water. I was so impressed that I’m now a believer in this product!"

"I really love bulk supplements. I've tried both the capsules and the powder forms, and I find the capsules much easier to take since the powder tastes disgusting. The EAA capsules do work, but you need to take the right amount to feel the effects. I usually take 5g before working out and another 5g after, and I don't exceed 10g a day."

"I've been taking amino acid supplements for a while now, and I appreciate how convenient these are before my workouts. They don’t leave any bitter aftertaste, and they are easy to swallow. I like these even more than my previous brand, which was out of stock. They're also a bit cheaper, and the quality meets my expectations."

"This product arrived exactly as described, and I believe it’s making a difference. I can work out longer and stronger now. I take it on an empty stomach with no issues, and I definitely plan to purchase it again."

"I've recently begun my fitness journey, and waking up at 4:30 AM to hit the gym can be tough. I wanted something that would give me energy without feeling jittery. I found this product, and it's delicious! I started with half a scoop, and now I take 2 or 3 depending on my workout. It has replaced my morning iced coffee, and I love how it helps me power through my day!"

"I used to struggle with energy mid-workout and would often have to cut my sessions short. Since I started using this product, that's no longer the case. The smooth energy boost it provides is fantastic, and I can keep drinking it with water without losing flavor. This is my favorite pre-workout, and I'm never looking back!"

"As a woman in my 50s, I did my research on what I need, and this product is just perfect. It's affordable and tastes great. I feel a slight tingle about 15 minutes after drinking it, but it dissolves quickly without any lumps. It's become a permanent part of my morning routine!"

"I've ordered this product twice now. I engage in a variety of workouts, from weights to running, and I've been using different aminos for a long time. After researching, I felt much safer taking Thorne. The flavor isn't the best when mixed with too much water, but I adjusted to about 20oz and it's been fine. New users might find the taste off-putting, but honestly, workout supplements used to taste much worse. My recovery and muscle gains remain consistent with previous products, so I prioritize product quality over taste."

"I generally enjoy Thorne products, but the taste of this lemon flavor is quite horrible. It's very strong and chemical-tasting, even overwhelming a smoothie. I'm truly disappointed as I'm not usually picky about flavors."

"After trying Kion, we switched to Thorne and VitaMonk. I prefer Thorne while my wife favors VitaMonk. Both are $10-15 cheaper per month than Kion, so we subscribe to both. The flavor is excellent, balancing sweetness while masking the amino taste. I'd like a bit more Leucine, but the essential amino acid levels are good."

"I read the title and ordered this essential amino acid supplement because it explained how it influences protein activity, which surprised me. I appreciate that it's GMO-free, sugar-free, gluten-free, and dairy-free. However, taking five pills daily is a bit much for me; I’d prefer to chew them. So far, I haven’t experienced any significant side effects."

"Having used many amino acids for health reasons, I really like this one. It’s less expensive than Kion Essential Amino Acids but seems to contain similar ingredients. I find them easy to swallow and completely tasteless."

"I’m excited to share my experience with the Ultimate Essential Amino Acid Supplement. These tablets are incredibly easy to swallow, unlike others I've tried before. There’s no unpleasant aftertaste, making them effortless to include in my daily routine. The 40% Leucine content and 4:1:1 BCAA ratio meet my body’s needs for sustained energy and mental clarity. The price is also very reasonable for such quality. This supplement has significantly boosted my energy levels and focus during workouts. I can’t recommend it highly enough to other fitness enthusiasts!"
