How Long Does It Take for a Multivitamin to Start Working?

How long does it take for your multivitamin to start working?

This is one of the top searched questions on most health websites. And for good reason! People want to know when their nutritional purchases are going to be paying off and they’re going to start feeling better.

This may seem like a simple question, but there are quite a few factors that go into determining the answer.

First off, you must define the term “working”. For the sake of this article, we can say that when you start “feeling better”, or notice more energy or improved brain function, or whatever your desired outcome may be. When you start to see results or health outcomes is when the effects are taking place. Any of these are desired benefits that come with taking a multivitamin regularly. Additionally, your multivitamin could be working when the signs and symptoms you first noticed prior to beginning the supplement have started to go away.

How Long Does It Take for a Multivitamin to Start Working?

Typically, any supplement such as a multivitamin that is added to a nutritional regimen takes two to four weeks to begin having noticeable effects within the body. This is when you likely will start to notice that things are working and stimulating change.

What Factors Impact How Long it Takes for a Multivitamin to Start Working?

There are several factors that can impact how long it takes for your multivitamin to kick in.

Here’s how to figure out how long it will take for your multivitamin to start having effects:

  1. 1. How severe your nutrient deficiency is
    • This is the biggest factor that determines how fast your supplement will start working. It depends how deficient you are in these essential micronutrients. Pretend your nutrient stores are a glass. If your glass is completely depleted it will take a lot longer to fill it up than a glass that is half or three fourths full.
  2. 2. The quality of the multivitamin
    • Supplements are currently unregulated products. This means standards can go out the door when it comes to companies trying to get by with cheap products. Often, there is label fraud that occurs. Supplement quality is one the most important things to think about when it comes to determining how well and how long it will take for a multivitamin to work. If you’re trying to fill up your glass with nutrients that don’t work, you aren’t going to make a difference. Seek out a company you trust that uses only the purest ingredients with strict inspection policies. Try our multivitamin.
  3. 3. The dosage you’re taking of the multivitamin
    • How much you are taking determines how fast it will work. With a multivitamin, the key is a low steady dose over time. This ensures your body absorbs all the necessary nutrients it needs in a timely manner. You can again think of the glass analogy. If you’re only filling it up a teaspoon at a time it is going to take more time to fill the glass. It doesn’t mean it is not filling, it just means it will take longer. The key is moderation. At the same time, you don’t want to just pour a whole pitcher of liquid into that glass. It will overflow and spill everywhere and cause problems.
  4. 4. Your root cause of deficiency
    • What is causing your nutrient deficiency? Is it medication? Is it due to your high level of stress at work? Are you eating a poor diet? These factors can play a role in depleting your nutrients. If you don’t address these root causes then no matter how much you keep trying to fill that glass up it will remain a rapidly depleting container. This is why integrative medicine is key to health. We must address the nutrient needs but also the root cause of health disorders.
  5. 5. Your diet and lifestyle factors
    • While supplements like multivitamins are necessary to good health, food is also one of the greatest, continual sources of nutrients we get every day. This means that we must make healthy food choices such as a Paleo diet. You must support your supplemental efforts with healthy food choices and lifestyle decisions. These two factors can help to make your multivitamin (or any supplement) work faster and better.

Takeaway Message:

A good multivitamin is an essential addition to any healthy regimen. There are several factors that will determine how fast your multi kicks in or starts to have an effect.  These factors include how severe of a nutrient deficiency you have, how good your multivitamin is, how much you take every day, what the root cause of your nutrient deficiency is and certain diet and lifestyle factors. Keep these things in mind as you begin taking your new, high quality multivitamin.

What’s the Difference Between Cheap Versus Premium Multivitamins?

We all want health and wellness. Most people who are sick would give anything to have their health back. Yet, most of us don’t have “anything.” Only so much money is available to prevent and treat disease.

Your multivitamin is not a place where you should skimp on money. The multivitamin is the foundation to your supplements regimen and foundation to health and wellness.

After all, even the best diets are deficient in certain nutrients. The soil, air, and water are not what they used to be. Organic broccoli grown in California and shipped across the country is not going to solve all your problems.

Trust me. I test people’s nutrient levels. Everyone is deficient in some vitamins and minerals, if not many of them.

Don’t skimp on your multivitamin.

The following chart is from the most popular store brand. You will see active ingredients and inactive. Their goal seems to be providing the minimum dosage necessary according to the RDA. These levels were created to provide the minimum necessary to prevent serious illness.

These doses are to survive, not thrive. Just a few of my comments are in RED.

All of the above vitamins and minerals are in the cheapest form possible and likely have very little benefit to the user.

This popular brand also includes tin and nickel in their formulation. These two metals have ZERO role in the body and only serve to interfere with body function. Why are they included? Who knows.

Maltodextrin is also listed as an active ingredient. Do they think this is for calories and considered a food? SMH. It seems like they WANT us to get sick. This is not a surprise given that the pharmaceutical company who makes this multivitamin also makes heart and cancer drugs.

Here is list of the some of the inactive ingredients. Beware, reading this list can make you nauseous and possibly vomit.

3 different kinds of corn starch (all GMO)

Polyethylene glycol- a laxative

Polyvinyl alcohol- used in papermaking, textiles and coatings

Titanium- metal with no role in the body

Talc- possible carcinogen with no obvious health benefits.

Yellow 6 Lake- artificial color. Others in this category have been found to be carcinogenic

Hydrogenated palm oil- artificial fat

All the above in a tablet that most people are not able to digest anyway, which in this case, may be a good thing.

You deserve better

Quality multivitamins use the best vitamins and minerals in forms that the body can use. The best multivitamins do not contain artificial colors, flavors, or additives like corn, soy or wheat.

Men and women who no longer have periods do not need iron.

Vitamin K2 is the preferred form for healthy bones and keeping arteries clean.

Folate and methylcobalamin provide the usable form of these B vitamins for many functions including control of homocysteine, a dangerous amino acid when levels are too high.

Magnesium and potassium are critical for every cell function. A multivitamin should provide high doses in quality forms like magnesium glycinate or malate. The typical magnesium oxide is cheap and poorly absorbed.

Lithium is a mood stabilizer and belongs in your multivitamin.

Inositol and choline along with bioflavonoids round out a quality multivitamin.

Finally, a multivitamin should be just that….multiple vitamins. It should not contain the kitchen sink. So many brands try to include too much with things like herbs and other plant remedies. These may be great, but do not belong in a multivitamin.

You get what you pay for.

If you are taking a cheap multi from your local drug store, don’t buy. Take quality or taking nothing at all.

You’re worth it.

With all the above stated, that is why we created our MULTI, multivitamin. The best ingredients without the added fillers. All that in an easy to digest capsule. The capsules may be opened into water, juice, or a smoothie.

What Are the Most Dangerous Ingredients Found in Common Multivitamin Brands?

Have you ever wondered how safe the popular supplements you see on your grocery store shelves are? Have you read articles questioning the safety and value of these top brands?

Ideally, we would get all the nutrients we need from food alone. However, in today’s day and age, this is just not realistic. Due to common factors like nutrient depletion of soil, industrial food production practices, pesticides, genetically modified foods and environmental toxins, it is virtually impossible to get adequate nutrition from food alone.

Our solution to this is to take supplements to ensure we’re getting optimal levels of micronutrients.  These days, doctors are also handing out vitamin sample packets like candy (more on this later in the article).

The question remains: what are the dangerous ingredients lurking in our everyday supplements such as the multivitamin?

These harmful ingredients are also likely the cause of the controversial studies questioning the health benefits of multivitamins in the first place.

Below are the top 5 most dangerous ingredients found in your daily multivitamin brands.

If you have found these ingredients in the products you buy, then stop buying them!

Instead search out high quality natural supplements from companies you actually trust that fill your body only with the good stuff.

Top 5 most dangerous ingredients found in your average multivitamin brands:

1. Artificial colors

Take a look at most traditional vitamin brand labels and you will see any of the following synthetic dyes listed and approved by the FDA.

  • FD&C Blue No. 1
  • FD&C Blue No. 2
  • FD&C Green No. 3
  • FD&C Red No. 3
  • FD&C Red No. 40
  • FD&C Yellow No. 5
  • FD&C Yellow No. 6

The question you should be asking yourself is, “Do I really want artificial colors in the multivitamin I’m taking to get healthy?”

The answer should be no.

These synthetic dyes have been linked to dangerous health consequences, especially for children. The three most commonly used dyes- Yellow No. 5, Yellow No. 6 and Red No. 40- contain compounds like benzidine that have been linked to an increased risk for cancers such as bladder and pancreatic cancers.

An article published in the International Journal of Occupational and Environmental Health stated that all of the current US-approved artificial colors pose health risks to some degree with the majority being listed as carcinogenic dyes1. Additionally, at least four of the dyes produce hypersensitivity reactions1. The article goes on to further conclude that there is no adequate level of safety testing that occurs with the use of any of these dyes1.

If you have a common multivitamin like Centrum or a children’s Flinstone’s multivitamin, throw them out now.

The worse part about all of these artificial additives is that they do not even improve the safety or nutritional quality of foods. They are just a cover up for the big food companies. 

2. Titanium Dioxide

Titanium dioxide is found in many of your cosmetics, sunscreens and even deodorants. Titanium dioxide is also found in your average multivitamin. It is used as a colorant and is considered a toxic additive. This compound is found in many common multivitamin brands such as Centrum Silver.

This common additive is linked to a number of health risks. It has been suggested to be a carcinogen. There haven’t been enough studies done to show the toxicity level of it in humans, however, animal studies on the inhalation of titanium dioxide have linked it to cancer formation.

Additionally, based on the rodent studies showing a link between titanium dioxide exposure and cancer, several studies have concluded that it is “potentially carcinogenic” to humans2. 

3. Polyvinyl Alcohol

Polyvinyl alcohols are a group of synthetic polymers used in a wide variety of industrial, medical and food applications. The CDC warns of contact with these types of compounds on their website stating a need to “avoid contact with polyvinyl alcohol” and to “wear gloves, wear safety goggles and don’t ingest it”3.

It is thought that this additive does have potential carcinogenic effects. Animal studies have concluded that it is tumorigenic and can increase cancer risk. It can cause skin, eye and digestive tract irritation. It has been linked to affecting behavior and the central nervous system including symptoms such as depressed activity and muscle weakness4.

Additionally, it can have effects on the blood and overall metabolism. It may also contribute to respiratory tract irritation.

This is alarming as this ingredient is found in common multivitamin brands such as Centrum.

4. BHT

This lab-made chemical is a preservative and it is also a carcinogen. It is found in typical products like Centrum Silver. Pick up just about any processed food product such as chips or common vegetable oils and you’ll likely see either BHT or BHA listed. The main function is usually to preserve food products and prevent oils from becoming oxidized and rancid.

There is currently ongoing controversy in the research world as to the safety of BHT. The FDA, of course, lists it as GRAS (or “gradually recognized as safe”). The National Toxicity Program, however, has found BHT to be unsafe citing its ability in animal studies to increase cancer risk. Likely for this reason, both U.S. and European regulations only allow for very small amounts of this chemical additive to be used in food processing. BHT is also added to embalming fuel and in the petroleum industry.

You can also find it in your grocery store’s popular multivitamins.

5. Talc

Talc is a mineral ingredient commonly found in cosmetics. It is used as a cheap filler and anti-caking agent. Talc is also used in supplements to prevent them from sticking to the machinery when the tablets are being formed.

The safety of talc has long been questioned as to whether it contains harmful contaminants such as asbestos. Both talc and asbestos are similarly found next to each other in the earth’s crust.

Talc has been found to cause lung problems upon inhalation. Again, during the processing of it, talc can become contaminated with asbestos, a known carcinogen. On the FDA website, they even talk about the need to prevent contamination of talc with asbestos when processing it during mining5. They go on to say that the safety of talc has been questioned since the early 1970s.

Studies in the 1960s found a link between talc and ovarian cancer. That’s also what many of the recent lawsuits with Johnson and Johnson’s talc based baby powder and occurrence of ovarian cancer were about.

Common sense would mean that if topical use of talc can cause cancer, then the talc that is found in your ingestible supplements will too.

Interestingly, the FDA doesn’t even regulate the type of talc that is to be used in supplements. Additionally, in order for talc to have no detectable levels of asbestos then it must be listed as “talc USP” but most popular multivitamins do not list their talc as “USP” grade. That is just some food for thought. 

The Solution:

Interestingly, the multivitamin brands you find these harmful, artificial ingredients and fillers in are also the brands that are packaged and sold under Big Pharma companies. For example, Pfizer owns Centrum. This is why doctors are now passing out sample packets of cheap vitamins at patients. It makes them more money.

Do you think these companies care about the health and quality of multivitamins they are selling to you? The answer is no. Do you think they are trying to improve your health and prevent disease with natural, high quality nutrients that are easily absorbed in your body? Again, the answer is no.

Find a company you trust (like the Drs. Wolfson) and get a natural multivitamin with absolutely no fillers, artificial ingredients or preservatives. This is the way to get healthy!

What Does a Multivitamin Do for You?

Multivitamins are the most commonly used supplements around the world.

Many people believe multivitamins are a cure-all that can make up for a poor diet and lifestyle along with protecting against chronic disease.

While this isn’t the case (you still need to follow that healthy Paleo diet), there are many health benefits to regularly taking a multivitamin.

The real question is what does the science say about multivitamins? Are they good for you? And what do they do for your body?

What is a multivitamin?

Multivitamins are a collection of micronutrients including essential and nonessential vitamins and minerals. Sometimes, they contain other ingredients, as well.

The concept of taking a multivitamin is a good idea. Due to many reasons such as soil depletion, modern agricultural practices, pesticides and environmental toxins, we are not able to get the nutrients we need from food alone and nutritional supplements are needed. Even with the best diets, nutrient supply is diminished. Additionally, there are other life factors like pregnancy and chronic disease that can impact multivitamin needs.

We like to think of multivitamins as a foundational supplement. They help to make sure all of your bases are covered.

In 2013, the Journal of the American College of Nutrition revealed that taking a multivitamin reduces total mortality and decreases both cardiovascular and cancer risk1.

What nutrients do multivitamins contain?

A good multivitamin contains all your required vitamins and minerals along with extra beneficial nutrients like bioflavonoids. Look for the basics like vitamin A, vitamin C, vitamin D and vitamin E. You also want to look for specific forms of vitamins like vitamin K2 not just vitamin K1. You will want specific types of vitamins such as “activated” or methylated B vitamins to ensure full absorption by the body. Ideally, you also want larger doses of your heart-healthy minerals like potassium and magnesium. Lastly, look for the key trace minerals like mood-stabilizing lithium, as well.

What does a multivitamin do for you?

  • Promotes overall health
  • Prevents nutrient deficiencies
  • Boosts your immune system
  • Provides natural energy support
  • Detoxifies your body
  • Improves cognition
  • Good for eye health
  • Supports healthy aging 

Are multivitamins harmful?

A good multivitamin is only beneficial not harmful. Yet it depends on the brand of multivitamin you choose. Choosing a high quality multivitamin is key to overall health.

Additionally, dietary supplements are not regulated so you can’t trust just any company. Many companies use artificial and harmful fillers along with poor, non-bioavailable forms of nutrients. Companies may also either provide more or less than the amounts of nutrients that are specified on the bottle. This is called label fraud and it can result in a product with a varied amount of nutrients.

Choose a multivitamin that is from a company you trust and one that is backed by scientific evidence.

Read more below about what to look for when selecting a multivitamin.

What to look for when selecting a multivitamin?

Multivitamins often go by several names such as “multis”, “multiminerals”, or simply “vitamins”.

You can also find multivitamins in different forms such as capsules, chewable tablets, gummies, powers and liquids.

When looking at multivitamins, the key is to choose a high quality one with pure ingredients that has been sourced well.  You want a product that is easy to digest and full of the right vitamins and minerals in the right form. Look for extra added benefits like antioxidants!

Be sure to:

  1. Know the company supplying the multivitamin to verify quality. We partnered with a company in business for over 40 years that only supplies products directly to doctors. Second to none.
    • This allows you to ensure there are no artificial fillers, genetically modified organisms (GMOs), sweeteners, allergens or preservatives.
  2. Look for appropriate levels of nutrients on the label.
  3. Make sure the essential micronutrients are all in there like magnesium, potassium, and trace minerals. .
  4. Ensure all of the nutrients are highly absorbable.
    • We use methylated B vitamins that are “activated” to make them more available to the body.

Takeaway message:

A multivitamin is a great option for nutritional support. These days, diet alone is not enough and nutritional supplementation is needed in order to get all of the essential nutrients for health benefits. Check out our multivitamin for your health and wellness needs.

Why Men With Cardiovascular Issues Need Multivitamins

Transcript of this Video

Hey, it’s Dr. Jack here. I want to talk to you today about why all men with cardiovascular issues need to be on a multivitamin.

As a board-certified cardiologist, I’ve seen the benefits and the value in using a multivitamin. You say you’re eating a good diet. Are you on an all organic, grass-fed, Paleo diet? Eating wild seafood? In a perfect environment? You’re obviously not.

Even the best foods and the best diets are deficient in certain nutrients and, because of our history, we’re deficient in certain nutrients because of the environment, the water, the air, the soil. Even the best foods are deficient and this is where our product comes in, or a high-quality multivitamin comes in.

I test people’s blood work on a daily basis. I look at their intra-cellular nutrients. Intracellular magnesium, potassium, copper, zinc, iron. We look for these levels and we find deficiencies in people all the time. People that are deficient in certain B vitamins, or vitamin C or A, D, E, K…on and on, we see all kinds of abnormalities.

Selenium is a tremendous detoxifier. A great source of that is Brazil nuts. But even still, once again, the soil is depleted, the water, the air, all the different problems. So, that’s where a multivitamin comes in.

A multivitamin is the foundation of a healthy supplements regimen.

I’ve seen so many people over the years that take different products. Maybe they take a vitamin C, maybe they take a magnesium, but you need that good base and foundation.

You want to find a product that contains all the nutrients you need but doesn’t have the fillers that you don’t need. So, classic things that we look for are any kind of artificial colors and flavors…that’s quite the obvious.

To me, a sign of a high-quality multivitamin is something that has methylcobalamin and methylfolate, which are two more expensive versions of vitamin B9 and B12. You look for a quality, healthy serving of vitamin K, specifically as vitamin K2. That’s what keeps the calcium in the bones and out of the arteries. A quality serving of magnesium and potassium.

But there are two things that I think are not necessary for men with cardiovascular disease. One would be iron. Two would be copper. Those are not necessary. People are not deficient in those. Typically, they have too much iron and copper so we don’t want to add that. Our multivitamin at The Drs. Wolfson does not contain that.

Over the years I’ve been very successful using our multivitamin with my patients. I take it personally. So does my wife. So do my two boys. None of us have cardiovascular disease, but we want to prevent it from forming.

So, until next time, make sure you are on a quality multivitamin. Cheers to health.
