Frequently Asked Questions


Why are Metabolic Research Center brand vitamins and supplements better than other brands?

Metabolic Research Center's formulations were created using the latest scientific studies as the basis for the types of ingredients and the amounts that go into our products. Many companies use only trace amounts of the ingredients used in much higher quantities in scientific studies. MRC works hard to make sure you're getting the right amounts of the ingredients, making it worth the time and money you invest in your health.

What are the dosage requirements?

Each supplement will have different dosages, which are included on the label for each product. Customers are asked to follow label instructions unless otherwise directed by their physician.

What should I do when the package or seals are broken?

Should your package arrive damaged or tampered with, do not take the supplements. Please contact us right away to arrange to return the product to us. Please email us at websupport@emetabolic.com if you have any questions. We will be happy to replace it for you.

Should I check with my doctor before I take these nutrients?

As with any change to your diet, we recommend you speak with your health care professional before starting any new weight loss program.

Do you offer gift certificates for these products?

Yes, Gift Certificates can be purchased in any amount from the gift certificate page under accessories above or click here.

The certificate will be emailed to the recipient after payment has been processed. Gift certificates purchased online are not valid in Metabolic Research Center locations, they can only be used online at weightlossmrc.com

If I eat properly, do I need to take vitamins?

Most of us don't get sufficient levels of all the nutrients needed to keep our bodies functioning at optimal levels. Notice we said OPTIMAL levels. You certainly can get by on less than perfect nutrition, but you won't feel and perform your best. Our modern lifestyles include less fresh food and more processed ones, which are often depleted of important nutrients. Supplements are an easy way to add on that extra level of nutrition we might be missing. But remember, supplements are just that - an addition to, not a replacement for - what you are already eating.

When is the best time to take supplements? Can they be taken together?

Here at Metabolic Research Center, we designed our supplements to be compatible with each other AND with your active lifestyle. They can be taken together. Unless otherwise stated on the bottle, the supplements can be taken whenever it is most convenient to you. It's best if they are taken at the same time each day. If you take them on an empty stomach and experience any sort of digestive discomfort, you can try splitting them up evenly throughout the day with meals.

Why can't I take one pill a day to get everything I need?

Although many companies might try to convince you that you can get a whole day's worth of vitamins in one tablet, in reality that's not possible. Think of all the vitamins, minerals, fatty acids, herbs and other components that can make you healthier, and you'll realize there is no way to fit them into one tablet. There is also a finite amount of nutrients that can be absorbed at once, which is why many of our products are designed to be taken more than once a day.
