Vitamins: Multi-Vitamin or Single Supplements? What You Need to Know

  blog post author icon   blog post published date icon   09/27/20


What exactly are vitamins? People believe that vitamins are good for them, and for that reason alone, many people take them. Some individuals supplement with individual vitamins while others pop a multi-vitamin. How does one know when they have received what they need from their vitamins? Can you take too many vitamins? Which ones? Learn about vitamins, the benefits they offer, and the best way to take them.

What Are Vitamins?

Vitamins are, by definition, various organic compounds required by mammals in small quantities to sustain life. Some vitamins aid in the regulation of metabolism. Others prevent disease, help one's blood clot, enhance nerve function, provide energy, and even help the body repair itself from stress. Ideally, all of the vitamins that people require would get supplied through their diet, but in reality, this rarely is the case, which is the basis for interest in vitamin supplementation.

Supplements fill in the gap for the nutrients that are missing from your diet

The government has issued recommendations called the Recommended Daily Allowance (RDA) for vitamins and minerals. While these recommendations are informative, they represent the minimum amount necessary for the maintenance of human health. Soil depleted from decades of factory farming produces food with far fewer vitamins than soil rich with organic matter. With supplemental vitamins, an individual might correct vitamin deficiencies that stem from worn-out soil.

What Do Vitamins Do?

Vitamins have a vital role to perform in the establishment and maintenance of human health. They aid in regulating growth through nourishment. When provided in small doses, vitamins help maintain a host of essential biochemical reactions that occur automatically in a well-nourished body. In far more significant amounts, both vitamins and minerals can sometimes act as natural medications, improving overall health and providing the body with the means to heal.

Why Supplement with Vitamins?

Vitamin supplementation aims to correct any dietary shortfalls that may be present. Unfortunately, it is often impossible to know what shortfalls might exist without actual blood tests. It is incumbent upon each individual to learn enough about their body's needs and available supplements to have an accurate view of their needs. For example, a vegetarian automatically knows that they need to supplement with B-12. Without eating meat, it isn't easy to get enough of this essential nerve-support vitamin.

What Vitamins?

Many people take vitamins to correct perceived deficiencies in their diets. There is not a one-size-fits-all vitamin supplement. Although all people need the same vitamins and minerals to experience optimal health, they all won't be deficient in the same vitamins. Vitamin deficiencies occur for different reasons, which, in turn, differ from person to person. These factors include a person's diet, the amount of stress they are experiencing, their medications, pre-existing diseases, whether they are a smoker, and many others. Most smokers are deficient in vitamin C. People who have high blood pressure or take certain high-blood pressure medications often have imbalances in calcium, magnesium, and potassium. Many other examples abound and are unique to each individual.

An initial examination of an individual's diet and current state of health helps determine what vitamins to take as supplements. Blood testing can give definitive results but aren't always necessary. Take the time needed to learn your symptoms and to learn the options available to you. Look further than your grocery store's shelves for your vitamins. Quality is essential, where supplements are concerned. No amount of quantity can account for a loss in quality.

Multi-vitamin or Single Supplement Regimens?

Sooner or later, everybody gets around to asking the same question: Should I take a multi-vitamin, or should I try and determine what I'm lacking and take supplements for those missing vitamins individually? People want to know which is better, but the answer is yes to both.1 However, not necessarily at the same time, and your choice of a multi-vitamin over single supplements may change back and forth as your needs change over time.

Each person is responsible for doing their due diligence. Still, it is easy to keep a food diary and then determine the amount and quality of nutrition present in one's diet. From there, study multi-vitamin formations and choose one that seems to fill the majority of your gaps. Then take a personal inventory of your health, and write down your ailments and the improvements you would like to make. Then determine which supplements might work best to correct your complaints.


It is always a good idea to run any change in your diet or vitamin regimen by your medical doctor. The last thing anyone ever wants to have occurred is a vitamin overdose.2 There are fat-soluble and water-soluble vitamins, and it is crucial to understand the difference between them. Water-soluble vitamins flush from the body when a person over-consumes them, assuming they have functioning kidneys. Fat-soluble vitamins are not excreted but remain in the body. Over time, a high level of supplementation of some fat-soluble vitamins can eventually build up to toxic levels.


A high-quality multi-vitamin serves many individuals well, with additional supplementation in critical areas from time to time. As a general rule, one takes added single supplements only long enough to correct an imbalance and then drops to an occasional or maintenance dosage. For example, suppose one were to get the sniffles. That individual might increase their intake of vitamin C, zinc, vitamin D3, and perhaps take an extra B-complex, all to hasten their recovery. Once they're well again, they stop the supplementation or drop back to a maintenance dose.

Other Considerations

As you explore the world of vitamins and supplements, consider the quality of the various available vitamins. Look for companies that offer independent analysis as proof that their capsules contain what they say they do. Work with companies that have legendary customer service. All multi-vitamins are not the same. Know what you need for your optimal performance and health, and then choose the vitamins that most closely match your need.

Vitamins are a powerful tool in your arsenal of health tips and tricks, and you need both single supplements and multi-vitamins at different times in life for various reasons.3 Individuals do well to adopt the attitude of having the right tool for the job because the right supplement is a powerful tool in the person who understands how to use it.

Shipping & Handling

A safe and accurate address for delivery must be provided at the time the order is placed. Once an order has shipped, is NOT responsible for lost or stolen packages CONFIRMED BY THE CARRIER to be delivered to the address provided for the order.

Since COVID-19, and the ensuing economic challenges in the USA economy, we respectfully ask that you allow some additional time for delivery for the carriers (USPS, UPS, and FedEx). Most orders still arrive on time, or near on time, but some may run late. We make every effort to get your order packed and into the carriers hands the same day, or by the next business morning if your order came in later in the previous day after carrier pickup, but we have no control over any delays that may happen within the shipping carrier's delivery system. Please order earlier for the time being if you are time-sensitive.

Orders that contain only FirstFitness Nutrition products have a shipping fee automatically calculated based upon the actual shipping weight of the items purchased. The charge ranges from $4.95 to $14.95.

For orders with NuMedica products you may choose from the shipping options below on the Order Checkout form in the Shipping Information section on the first line that says Choose Shipping Method.

International Shipping

Shipping anything these days internationally is expensive. COVID resulted in more rigorous customs import processes, and now with much higher energy prices, international shipping rates are higher.

FedEx is the most reliable and faster carrier, at least for now, but they are expensive. Our FedEx international shipping fee is a minimum of $79.95. It usually makes more sense to get several months of supply (3 months or more) in one order to minimize the shipping expense per order over time. While the added weight of additional items may increase the base shipping price by a little (usually 10-25% depending upon total weight and destination), it is usually not by very much relative to shipping an additional small order later.

We also offer a lower-cost international shipping option using GlobalPost International for $39.95. So far, they have been reliable in getting packages correctly delivered but it takes 2 - 4 times as long to get the package delivered. Packages may take longer to process in the receiving country's customs process and status updates may not be reported as quickly. Please be patient if you choose this option to save money.

Some International orders may cost more to ship depending upon weight and location. If that happens we will contact you first and get your approval for any additional charge before proceeding. International orders may also be subject to additional customs fees and duties/taxes based upon the destination country's customs import laws and policies. These fees are NOT known or included on our order form and are typically charged and collected by the shipping carrier when they are delivering the product to it's final destination once the package has cleared the destination country's customs process. It is recommended that the buyer research custom import fees for the products/services they are importing beforehand to be aware of potential, additional fees.

Shipping Refrigerated Products

Our manufacturers formulate their probiotics to ensure their products retain viability until they reach the consumer. Probiotics that are recommended to be refrigerated remain so until the time of shipment, then shipped alongside an ice pack to ensure potency (Note: Ice pack will not arrive frozen, and product may not arrive cold). Orders placed on a Thursday-Sunday requiring cold shipping will not ship until the following Monday.
