When you walk through your local supplement shop, you may be surprised to find that the same ingredient can have a wildly different dosage depending on the brand.
Some brands will put in less to cut cost while other brands go above and beyond ensuring to use the exact dosage you need to see results.
Do you know what the ideal dosage is for your favorite supplement ingredients?
Let's take a look at the top 5 most popular supplement ingredients and the scientifically proven dosage for each.
How Much Whey Protein Should You Use?
Hands down, the staple of the supplement industry, whey protein offers a variety of benefits. It offers muscle protection from breakdown, increased lean tissue growth, and supports recovery. It is also one of the most debated supplements for an appropriate dosage. (1-5)
The amount of whey protein you should use depends on what your goals are. On a daily basis, if your goals are muscle growth and promoting anabolic environment, you'll want to use a whey protein twice per day. The amount per serving should be between 25 and 30 grams of protein. This will vary by brand so you'll have to adjust accordingly.
Per serving: 25 to 30 grams
How often: Daily
How Much Beta Alanine Should You Use?
Found in nearly every pre-workout on the market, Beta Alanine is an amino acid that helps to support intra-workout performance along with recovery. Its most notable feature is that flushed feeling you get in your neck and face when taking it. (6-8)
The industry standard for Beta Alanine is 1,200 mg (1.2 grams) per day, typically taken pre-workout. Depending on your bodyweight, activity level, and goals, you can take up to 2,000 mg (2 grams) per day to support performance and recovery.
Per serving: 1,200 mg (1.2 grams) – Up to 2,000 mg (2 grams)
How often: Daily

How Much Glutamine Should You Use?
Glutamine, considered the counterpart to Creatine, is one of the most effective and popular supplement ingredients for sports recovery and promoting lean muscle gains. It's also used to alleviate stomach inflammation, which is great news if you have a sensitive stomach. (9-10)
For the average person, you can supplement with 5,000 mg (5 grams) of Glutamine per day. Again, based on your bodyweight, goals, and activity level, it is safe to increase that amount to 10,000 mg (10 grams per day).
Per serving: 5,000 mg (5 grams) – Tolerable up to 10,000 mg (10 grams)
How often: Daily
How Much Creatine Should You Use?
Famously used by the bodybuilding crowd long before it hit the general market, Creatine is one of the best pre-, intra-, and post-workout supplements you can use. It directly supports energy production for muscle tissue, sports performance, and boosts recovery. (11-12)
Studies show that 5 grams of Creatine is the industry standard but it is tolerable up to 20 grams per day during a loading cycle of 7 to 14 days. Although studies have demonstrated the safety of Creatine over the long term, you still may want to cycle off of it after one month of consistent use.
Per serving: 5,000 mg (5 grams) – Tolerable up to 20,000 mg (20 grams)
How often: Daily – May require an off-cycle after one month of consistent use
How Much D-Aspartic Acid Should You Use?
Finally, we have one of the best all-around fitness supplements. D-Aspartic Acid may be able to amplify testosterone levels in men while supporting strength, lean muscle, and performance. This is, without a doubt, one of the most common under-dosed supplements out there. (13-14)
3,000 mg of D-Aspartic Acid is the industry standard but it's not always easy to find a supplement with this amount. For men looking to increase their testosterone levels, you'll take 3 grams twice per day.
Per serving: 3,000 mg (3 grams) – Up to 6,000 mg (6 grams) for men wanting to increase testosterone levels
How often: Daily
