Your Top Supplement Questions Answered

You asked, we answered! Here are your top supplement questions:

How do I know if creatine is really working?

Creatine increases your body's production of ATP (adenosine triphosphate), the main energy source for cells. After you take creatine, you should feel energized, alert, and ready to crush your workout--and you may notice that you're able to work out longer tthan you used to. This will lead to noticeable results in your endurance, muscle tone, and strength.

When's the best time to take creatine?

Because creatine improves your energy, we recommend taking it about 20-30 minutes before you hit the gym. Some people take it after exercising to keep their energy levels up, but you don't need to if you'd prefer to take it once as a preworkout.

There are so many kinds of creatine and whey supplements; which one should I take?

This depends on your fitness goals and what works best for your body. Here's a quick breakdown of the different types of each:

Creatine HCL -Creatine HCL (hydrochloride) dissolves more easily in water and liquids than other forms of creatine.

Creatine Monohydrate - This form of creatine is more concentrated than others, and when it's micronized, it also dissolves well in water.

Creatine Ethyl Ester HCL  - Creatine ethyl ester has a better absorption rate than other forms of creatine, and if you have gastrointestinal issues, ethyl ester may be the right creatine for you; it generally doesn't cause digestive issues.

Whey Protein Isolate 90% - This powder contains 90% protein and a complete amino acid profile.

Whey Protein Concentrate 80%This powder contains 80% protein and a complete amino acid profile.

Hydrolyzed Whey Protein Isolate - "Hydrolyzed" means that this form of whey has been broken into small segments to promote rapid and easy digestion. It may also have a faster absorption rate than other types of whey.

Grass-Fed Whey ProteinThis form of whey isolate comes from grass-fed dairy cows.

Organic Whey ProteinAs the name suggests, this whey protein is organic.

If a supplement doesn't dissolve easily in water, does that mean it won't dissolve in my stomach?

You don't need to worry about this! Your stomach contains acids that help you break down and digest food, including supplements. Think about it this way: if you put, say, a piece of fruit in a glass of water, it won't break down immediately, but it does start to break down as soon as it hits your digestive tract. Don't sweat this one-- your body's got you covered.

Why do I feel "tingly" after taking beta-alanine?

You probably remember it well: it was the first time you tried beta-alanine, and you were killing your workout.

And then, all of a sudden, you got the tingles. Kind of like when your foot falls asleep except, you know...everywhere.

What the heck?

It may feel weird, but this is nothing to worry about. That tingling is technically called paresthesia, and while scientists aren't exactly sure why beta-alanine causes that characteristic numbness and itching sensation, they think it has something to do with the way beta-alanine interacts with your nervous system. It's completely normal, harmless, and should subside after a few minutes.

What supplements can I take on a keto diet?

Keto diets (short for ketogenic) are high in fats and low in carbohydrates in order to induce ketosis, a metabolic state that forces the body to burn fat for energy instead of sugar, potentially leading to quicker, more consistent weight loss.

If you opt to take supplements while on a keto diet, here are some options to help replenish electrolytes lost on a low carb diet, or that fit the low carb and/or high fat requirements:

Conjugated Linoleic Acid (CLA)

Fish Oil

Omega 3s





Talk to your nutritionist for recommendations on more vitamins and minerals that compliment a keto diet.

What is the difference between a powder and an extract?

An extract is made by extracting part of raw materials, like plants, flowers, and foods. Extracts are popular because they often use elements within the raw material--like antioxidants or plant compounds--that enhance the product's health benefits. Extracts are sold in oil and powder form.

An extract can be a powder, but just because a supplement is a powder doesn't necessarily mean it's an extract.

Is my supplement gluten-free?

Our supplements always contain allergen information on the label, so if a product does contain gluten, we make that explicitly clear. However, very few pure supplements actually contain gluten. Unless your supplements come from a source that naturally contains gluten or has fillers, flavorings, or additives, you should be safe.

Can I take creatine and caffeine together?

Many people do mix creatine and caffeine, but we advise against it. This is because both creatine and caffeine boost your energy. Combine the two of them together and it might feel like you've had way too many cups of coffee: an accelerated heart rate, sweating, nausea, headaches, increased anxiety and potentially even more dangerous side effects. Stay on the safe side and alternate your supplementation by taking creatine one day and caffeine the next.

What are the best supplements for building muscle?

The key to building muscle is weight training and protein, which means whey protein and BCAAs will be your best friends after you hit the weight rack.

BCAAs (branched chain amino acids) are the building blocks of protein, which in turn builds strong, lean muscle. Add BCAAs to your preworkout drink to build and maintain muscle throughout your gym session.

Whey protein contains a complete amino acid profile, giving you everything you need to build muscle. We recommend taking whey within 30 minutes of completing your workout.

Of course, whey and BCAAs aren't your only options. You can check out all of supplements for muscle here.

What are the best supplements for weight loss?

Some of our favorites are green tea, which contains fat-burning caffeine and compounds that may accelerate weight loss, CLA, and guaranaAlways pair weight loss supplements with a healthy diet and lifestyle, and talk to your doctor before taking any supplements. (Check out all of our weight loss supplements here.)

Where is my product from?

We source our supplements from all over the world, including South America, New Zealand, Asia, Europe, and North America. For detailed information on specific products, please contact us at

What does "HCL" mean?

"HCL" stands for hydrochloric acid, a mineral acid that is often added to supplements so they'll dissolve in water, and so your body can digest them easily. It's a safe substance that won't interfere with a supplement's benefits.

A supplement made me feel sick. Why?

There are multiple reasons why a supplement may not agree with you:

You didn't take the recommended dose.  It's extremely important to follow dosage instructions on a supplement label. If you exceed the dose, you could experience negative side effects, especially with products that contain caffeine. Never take more than the label recommends unless your doctor advises it.

You have an allergy or sensitivity. Everyone's body is different, and supplements that agree with one person may not sit well with another. If you think a supplement may not agree with you, avoid it and try another one with similar benefits--and be sure to check the label for allergy information.

You took it on an empty stomach. Sometimes, supplements digest better when you take them with food. Unless explicitly stated on the label, don't take supplements on an empty stomach.

It interacts with your medication. Some supplements like ginseng and grapefruit extract have been shown to interact with certain medications, and the combination of the two might make you feel ill. Do your research before adding a new supplement to your routine if you're taking medication for preexisting health conditions.

Why does my supplement taste bitter?

BulkSupplements' products are completely pure and free of additives, fillers, and flavorings--this means if you order our BCAAs, you'll get pure, unflavored BCAA powder. This is good news for you--first, because your supplements won't contain unnecessary and potentially unhealthy additives, and second, because it allows you to add your own flavoring so you're in control of your nutrition.

But sometimes, supplements in their natural state don't exactly taste like dessert. Don't freak out--this is normal. You can remedy any earthy or bitter tastes by mixing powders into smoothies, flavored water, or the drink of your choice.

My glutamine powder smells like ammonia. Did it go bad?

Nope! Chalk this one up to science--glutamine's chemical makeup naturally produces this smell. It's perfectly safe to consume and the smell should dissipate after you open the bag. If it bothers you, wait a few days until the smell is gone to take your glutamine powder.

Can I mix two or more powders together and store them in one bag?

You can mix our powders, but we recommend mixing them each time you take them, rather than immediately mixing all of them into one large bag. This is because when you combine powders, it's difficult to determine how much of each powder is in the mixture, which is something you need to know in order to take the correct dosage.

Instead of immediately blending all of your powders together, measure them out each time you take them to ensure you're not taking too much or too little.
