Water-soluble vitamins (vitamin C and the B-complex vitamins, such as vitamin B6, vitamin B12, and folate) must dissolve in water before they can be absorbed by the body, and therefore cannot be stored.
Except for B-12 and folate which are stored by the liver, most B-group vitamins can't be stored by the body. They must be consumed regularly in a healthy diet that includes a range of wholefoods (such as lean meat, fish, wholegrains, fruit, vegetables and legumes) and limits the intake of alcohol and processed foods.
The B-group vitamins are a collection of 8 water-soluble vitamins essential for various metabolic processes. Most of these vitamins can't be stored by the body and must be consumed regularly in the diet.
Vitamin C is cannot be stored in our body because it is a water-soluble vitamin and gets excreted from the body with sweat or urine.
Like the other fat-soluble vitamins, vitamin D is stored in the body's adipose (fat) tissue. That means your body can mobilize its own reserves if your daily intake falters temporarily — but it also means that excessive doses of vitamin D can build up to toxic levels.
Vitamin B12 is stored in excess in the liver, decreasing the likelihood of deficiency. However, in cases in which vitamin B12 cannot be absorbed, for example, due to dietary insufficiency, malabsorption, or lack of intrinsic factor, hepatic stores are depleted, and deficiency ensues.
You should be able to get all the vitamin C you need from your daily diet. Vitamin C cannot be stored in the body, so you need it in your diet every day.
Taking vitamin B-12 with vitamin C might reduce the available amount of vitamin B-12 in your body. To avoid this interaction, take vitamin C two or more hours after taking a vitamin B-12 supplement.
It's not advised to take vitamin C and vitamin B-12 at the same time, says Litt. That's because high doses of vitamin C can reduce the amount of vitamin B-12 that's absorbed and metabolized by the body, she says. Be sure to take vitamin C at least two hours after vitamin B-12. This way, you can avoid a B-12 deficiency.
A minimum daily dose of each vitamin is necessary to maintain good health. Significantly exceeding this dose, however, can cause illness. In general, the symptoms of vitamin toxicity include nausea, gastrointestinal problems like constipation and diarrhea, hair loss, rashes, and nerve damage.
B complex vitamins are a combination of several B vitamins that are essential for your body, including B12. However, taking B12 as a separate supplement can provide more targeted support for certain conditions.
Caffeine has a mild diuretic effect, which leads to an increase in urination. As a result, water-soluble vitamins, such as B-vitamins and vitamin C can be depleted due to fluid loss. Research also demonstrated that the higher the level of caffeine, the more it interfered with vitamin D absorption.
Poisonous Ingredient. Any ingredient in a multiple vitamin supplement can be toxic in large amounts, but the most serious risk comes from iron or calcium. Additional risks are associated with large or toxic doses of calcium, vitamin D, and vitamin A.
Don't use calcium, zinc, or magnesium supplements at the same time. Also, these three minerals are easier on your tummy when you take them with food, so if your doctor recommends them, have them at different meals or snacks.
Vitamin C is effectively an acid (it's sometimes known as ascorbic acid), so layering it with AHAs and BHAs like glycolic, salicylic, and lactic acids is a big no-no.
Vitamin C and Vitamin D are two essential nutrients that play important roles in the body and help to maintain overall health and wellness. You may be wondering, “Can I take Vitamin D and C together?” The answer is… Yes. In fact, when taken together, they're a powerful combo that can support the immune system.
Although the functions of vitamin C and magnesium may not overlap like other nutrients, there's no harm in taking them simultaneously. With no known interactions, vitamin C and magnesium can safely be supplemented together.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
Risk factors for deficiency include alcohol intake, tobacco use, low-income, male gender, patients on hemodialysis, and those with overall poor nutritional status. Although vitamin C deficiency is common, even in industrialized countries, overt scurvy is rare.
Lack of vitamin B12 and iron deficiency can cause anemia and lead you to feel cold. Good sources of B12 are chicken, eggs and fish, and people with iron deficiency may want to seek out poultry, pork, fish, peas, soybeans, chickpeas and dark green leafy vegetables.
Based on its anti-oxidant activity, we can suppose that vitamin C is preferentially accumulated in metabolically active organs, such as brain, lung and heart.
