Can Vitamins Make You Tired?

Have you ever felt tired after taking multivitamins? This may sound surprising to you, as vitamins play a crucial role in growth, development, disease prevention, and improving immunity. However, excessive vitamin intake can also negatively impact your body.

So, to learn more about ‘Can vitamins make you tired?’, head down below!

Can Vitamins Make You Tired?

Excessive vitamin intake can make you tired and put you at risk of experiencing other negative symptoms like nausea, vomiting, or depression. For vitamins to cause negative effects, they should be taken more than the daily allowance for an extended period of time. However, these negative effects vary according to the intake of specific vitamins. 

There are two kinds of vitamins: water-soluble and fat-soluble. Water-soluble vitamins include vitamin C and the B complex. Fat-soluble vitamins include vitamins A, D, E, and K. Some of the negative impacts of vitamins are mentioned below.

Negative Effects Of Water- Soluble Vitamins

Toxic effects of vitamin C occur when you take a large dose of about 3 to 5 grams. It can cause gastrointestinal problems like diarrhea and bloating. It may also put you at risk of having urinary calculi formation. 

Excessive dosage (> 3000 mg/ day) of vitamin B3 (Niacin) can cause fatigue and other health conditions, including skin flushing and itching and gastric and hepatic disorders. Vitamin B9 (Folate) does not cause tiredness directly but is associated with masking symptoms of vitamin B12 (cobalamin) deficiency, which is the main cause of fatigue. It can also exacerbate vitamin B12-associated anemia and cognition issues. 

Vitamin B6 (pyridoxine), if taken > 200 mg per day, is reported to cause sensory neuropathy and ataxia.  No toxic effects have been reported for Vitamin B1 (Thiamine) overdosage. However, in rare cases, it can cause anaphylactic shock and minor allergies if it is taken via the parenteral route. 

Negative Effects Of Fat-Soluble Vitamins

Overconsumption of Vitamin A may cause hepatotoxic effects, vision blurring, dry or itchy skin, and hair loss. In severe cases, if it is taken > 5000 IU / day,  it can lead to hip fracture. 

Vitamin D toxicity occurs from over-supplementation rather than over-exposure to sunlight. It causes tiredness along with growth retardation, renal disorders, and hypercalcemia (if you take more than 2000 IU per day). It also causes bone loss by increasing bone resorption. 

Vitamin E also causes fatigue and antiplatelet effects if taken more than 800 IU / day.   

How Can Vitamins Make You Tired

Many people continue taking vitamins for months and years without being aware of vitamin toxicity. So, how can vitamins make you tired and cause other adverse effects? 

Vitamin toxicity may be acute or chronic. Acute toxicity may result from the intake of one or more multivitamin supplements. Chronic symptoms develop gradually after extended use of multivitamin supplements. It gradually starts to cause tiredness, dizziness, headache, gastrointestinal problems, and other health conditions. 

Since fat-soluble vitamins accumulate in your tissues, their intoxication symptoms are more pronounced. Water-soluble vitamin intoxication is not life-threatening, as these vitamins are excreted out of your body via urine, and intoxication can be reversed. 

Can Vitamins Make You Sleepy

Although vitamin overdose leads to a variety of negative symptoms, it can also make you sleepy. Vitamin A, and some vitamins B, C, and D are known to promote sleepiness, and their deficiencies are linked with sleeping issues. Some of them are mentioned below:

Vitamin A

Vitamin A can improve your sleep quality, but its deficiency can cause sleeping disorders. However, an overdose can result in adverse effects within hours, like drowsiness, headache, nausea, and vomiting.

Vitamin B

Vitamin B6 improves sleep, and its deficiency is linked with insomnia and depression. Vitamin B9 can reverse sleep deprivation, and vitamin B12 directly regulates your sleep-wake cycle. 

Vitamin C

Vitamin C promotes sleep quality and duration by increasing the length of your sleep. It reduces the chances of having sleep apnea.

Vitamin D

Vitamin D plays a key role in regulating the sleep cycle. Its deficiency may lead to sleeping disorders. Vitamin B12 and vitamin D can directly impact your sleep cycle.

Vitamin E

Vitamin E combined with vitamin C greatly improves sleep quality and sleep apnea. 

According to research, people who take multivitamins experience awakenings from sleep multiple times at night. However, no evidence suggests a direct link between vitamins and poor sleep. 

Why Does Vitamin B12 Make Me Sleepy

Vitamin B12 can make you sleepy if you take it regularly as it enhances the production of a hormone called melatonin that regulates your sleep-wake cycle. As a disrupted circadian rhythm can cause depression, taking vitamin B12 may also decrease the risk of having depression. 

However, higher amounts of vitamin B12 specifically impact sleep by shortening the sleep-wake rhythm

Why Does Vitamin D Make Me Sleepy

Vitamin D has both a direct and indirect link with sleep. Vitamin D can make you sleepy as it takes part in the pathways of melatonin production. Vitamin D receptors and enzymes are present in many brain areas and are responsible for regulating your sleep cycle. 

It also indirectly improves sleep quality associated with non-specific pain disorders, such as restless leg syndrome or sleep apnea.
