1. What are fat-soluble vitamins? 

Fat-soluble vitamins are stored in your body’s fatty tissue, often for long periods of time (unlike water-soluble vitamins, which are usually quickly excreted out of the body). They include vitamins A, D, E and K.

Like all vitamins, they’re key for healthy body function, so it’s important that you’re getting enough of them. If you stick by a low-fat, vegetarian or vegan diet, make sure you’re supplementing these essential vitamins as you might not be getting what you need from food alone.

2. Why are vitamins important?

Because they help make your body work!

More importantly, while you do get vitamins, minerals and nutrients from your diet, chances are you’re not getting everything you need to fuel your fitness and wellness goals.

Vitamins fall into two basic categories:

Fat soluble and water soluble. And their names help you identify how they work.

Fat soluble vitamins A, D, E and K dissolve in fat and you store them in your body; water soluble vitamins C and B-complex (including B6, B12, niacin, riboflavin and folate) vitamins must first dissolve in water before your body can use them. Unlike fat soluble vitamins, your body does not store them, so you need to get them from food or supplements daily.

Almost anything your body does is on the table here:

  • Heart, Brain & Eye Health
  • Immune System Strength
  • Normal Growth & Development

So if you’re unsure if you’re getting exactly what you need to support your daily goals from diet alone, then head in to your local GNC store and talk to one of our associates.

3. What is the best time of day to take vitamins and supplements?

The best time is probably whenever you’ll remember to take them and when it’s most convenient to take them. That said, there are benefits to taking some supplements at specific times:

Multivitamins: Many people find that taking a multi on an empty stomach can cause stomach discomfort, so try taking it with food.

Protein: Ingesting rapid-absorbing protein within 30 minutes of a workout (along with some carbs) helps maximize results. Evenly distributing protein intake throughout the day helps support muscles, metabolism and appetite. A slow-absorbing protein (like casein) before bed helps prevent muscle breakdown and support repair while your body is at rest.

Amino Acids and BCAAs: To maximize muscle recovery and repair, a post-workout formula rich in aminos (particularly BCAAs) is ideal within 45 minutes of your workout.

Caffeine: Caffeine and other stimulants can be taken right when you wake up or within 60 minutes of a workout. Avoid caffeine later in the day to prevent sleep disruptions.

4. What are nutritional supplements?

The simplest way to explain nutritional supplements is that they provide essential nutrients that you’re not getting from your diet alone—or, they’re giving you more of what you need to meet daily recommendations.

The basics include things like:

  • Multivitamins
  • Omega-3 Fatty Acids
  • Amino Acids
  • Caffeine
  • Protein
  • Fibre

They come in a wide variety of forms, from tablets, capsules, and softgels to powders and ready-to-drink mixes to seeds, chews, and energy bars.

And whether you’re looking to target a specific fitness goal, simply looking to get more active or you have a wellness recommendation from your doctor, we can help you find exactly what you need. Stop by your local store to talk to an associate.

5. How many vitamins are there?

There are 13 essential vitamins. They keep your body healthy and can be divided as fat-soluble and water-soluble.

The fat-soluble vitamins are stored in fatty tissue and are more easily absorbed by your body when accompanying dietary fats. They include vitamins A, D, E and K.

The water-soluble vitamins dissolve easily in water and are often quick to be excreted by your body. They include vitamins B1, B2, B3, B5, B6, B7, B9, B12 and C.

6. What are vitamins and minerals?

The first thing you should know? They’re essential.

Here’s why:

They work together to help perform and support literally hundreds of everyday things your body does.

Vitamins and minerals can help strengthen bones, skin and your immune system to help build them up before something bad happens.

Vitamins are organic—made by plants and animals—while minerals are inorganic—coming from the soil or water and absorbed by plants or eaten by animals.

And that’s just the start.

Want to know what vitamins and minerals are right for your fitness and wellness goals? Stop by your local GNC store and speak with an associate. Just ask. We make it simple.

7. How long does it take for supplements to work?

As you may have guessed, this depends on what supplements you’re taking. While you may feel the effects of a pre-workout within 30 minutes, you should expect to wait six to eight weeks before you start to get optimum results from your multivitamin. Your body’s reaction won’t be the same for every supplement, nor will its reaction time.

Sure, we often want to see immediate change, but just remember that old adage “Good things come to those who wait.” Whether you’re trying a new diet, starting a new fitness routine or changing up your supplement regimen, patience often pays off. After all, isn’t feeling healthier worth the wait?

Stop by your local GNC store and let our associates help you determine how long you should expect to wait before you see results from your specific supplements.

8. What are the best supplements?

This is a big question that can only be answered by asking you a question in return: the best supplements for what? Every person is different and has different goals, so the best regimen is the one designed specifically for you.

There are, of course, nutritional products that benefit every person:

  • a multivitamin, to fill nutritional gaps in your diet
  • a probiotic, to support immune and gastrointestinal health
  • omega-3s, for heart, brain, joint, eye and skin health
  • protein, to support lean muscle and pretty much every other physiological process in the body

But even those nutritional foundations come in dozens of varieties based on factors such as age, gender and targeted health needs.

How do you know which formulas to take? What other supplements should you consider?

It sounds complicated, but it doesn’t have to be. That’s what GNC store associates are here for.
