Buy Vitamin D Supplements

Also known as the sunshine vitamin, this supplement is central to healthy bones, hair and teeth. Vitamin D is a nutrient that helps the body absorb calcium and boosts immune function and cell growth.

When you get enough sunlight, your body naturally produces vitamin D, but deficiencies can lead to severe health problems. Luckily, you can substitute a lack of sun exposure with supplements, which replicates the natural production of this vital hormone.

If you're looking for cost-effective vitamin D supplements that don't cost the earth, you're in the right place. We offer a year's supply for just £5, giving you significant savings that mean you never have to compromise on your health.

High-quality, environmentally friendly, excellent value

It's hard to find vitamins that don't impact the environment and offer great value for money. Most people think that to get high-quality vitamins, they must sacrifice their wallets or the environment.

Sealions vitamins are different. We have a wide range of products that cover all your vitamin needs, and we're also eco-friendly. We use fully compostable pouches and lower our margins so you can boost your health without spending a fortune each month.

While vitamin subscription companies can cost around £30.00 a month, we offer you supplements at a fraction of the price.

Why take a Vitamin D supplement?

Vitamin D is one of the most critical supplements for better health, and deficiencies can lead to various issues. While it's known as vitamin D, the 'vitamin' is actually a hormone that gets a natural boost from sunlight.

According to a CDC report, vitamin D is one of the most common deficiencies in the UK, but supplements can give your body a much-needed boost.

Improved immune system

Vitamin D is essential for many bodily functions, including immune system regulation. Numerous studies suggest that vitamin D deficiency can lead to a weakened immune system, increased susceptibility to infection, and delayed healing.

In fact, specialists associate vitamin D deficiency with autoimmune conditions (MS Society) and while we need more research to confirm this, taking supplements could reduce the effects of certain diseases.

In contrast, adequate vitamin D levels can improve your immune health and reduce the risk of certain infections. It essentially acts as a regulator and can balance your system, which keeps people free from disease.

Stronger & healthier bones

Vitamin D is essential for strong and healthy bones as it helps the body to absorb calcium, which is necessary for bone growth. When your body doesn't produce enough vitamin D, it won't be able to use calcium, which can lead to weaker bones.

Young people with a deficiency can develop a condition known as rickets, which weakens the bones and causes deformities. In adults, the condition is called osteomalacia (also known as a softening of the bones).

In the case of a long-term deficiency, osteoporosis can occur. It's treatable, but there's no cure, and weakened bones can lead to a lot of pain and damage your posture. Calcium is instrumental for creating strong bones, and maintaining vitamin D levels will dramatically reduce your risk of rickets and osteoporosis.

A safer pregnancy

Vitamin D is essential for pregnant women as it helps the body absorb calcium, which is necessary for developing the baby's bones and teeth. A deficiency can also cause pre-eclampsia, leading to high blood pressure and increased risk of complications during pregnancy.

While the best source of vitamin D is exposure to sunlight, many women do not get enough sun exposure during pregnancy. As a result, taking a daily vitamin D supplement is vital for pregnant women.

How does vitamin D deficiency impact the body?

People with a vitamin D deficiency might not notice any symptoms initially, but the lack of nutrients can put you at risk of calcium-related diseases or a severe hormone imbalance.

There are plenty of symptoms you might experience, but these are the most common:

  • Weak muscle function
  • Fragile bones/osteoporosis
  • Muscle twitches
  • Pain in the muscles
  • Stiff joints
  • Feeling tired

Taking vitamin D supplements daily will keep your bones and muscles healthy and reduce your risk of developing certain conditions.

RECOMMENDED DAILY DOSE: 

  • Babies up to 12 months old: 10mcg (400 IU)
  • Children 1-18 years old: 15mcg (600 IU)
  • Adults - 15mcg (600 IU)
  • Senior citizens: 20mcg (800 IU)
  • Pregnant and lactating females: 15mcg (600 IU)

COMMON SOURCES OF VITAMIN D:

  • Sunlight
  • Oily fish
  • Mushrooms
  • Fortified milk or cereals and juices
  • Egg yolks
  • Beef liver
  • Cheese

Are you at risk of Vitamin D deficiency?

While sunlight ensures the body can naturally create vitamin D, some people are more at risk of deficiencies than others. Here are some of the factors that might make you more susceptible.

Skin pigmentation

While you might think that living in a country with more sunlight can reduce the risks of low vitamin D levels, studies show that some of the warmest countries in the world have a higher prevalence of deficiency (The Lancet).

People with darker skin have been found to be more at risk of deficiencies, which can turn into hyperpigmentation. When this happens, the body is less effective at absorbing UVB rays, resulting in less vitamin D.

Lack of sun exposure

Natural sunlight is a central part of vitamin D absorption, and people that work night shifts can develop deficiencies. Sleeping during the day or living in a country with minimal sunlight are common risk factors, and housebound people are more likely to have problems.

Older people

As a person ages, their body cannot utilize vitamin D as effectively as younger people, resulting in deficiencies. Older people usually spend more time inside, which can lead to less sun exposure, worsening the problem.

Obese individuals

You're less likely to absorb the vitamin effectively if you have a higher than average body fat percentage. Individuals with a gastric bypass might also have problems with a regular supplement dose, but taking more vitamin D can prevent deficiencies.

Fat absorption issues

As vitamin D is a fat-soluble supplement, your gut is directly responsible for processing it. If you have a condition that limits the effectiveness of your gut, it can lead to deficiencies.

Breastfeeding women

When a woman breastfeeds her child, she shares any minerals and nutrients with the baby. Therefore, women need to top up their levels and ensure that they and baby get the recommended daily intake.

The problem with this is that most of your money goes into the company's back pocket and on fancy packaging. It doesn't need to be this expensive, and we're all about disrupting the norms.

When you shop with us, you can take advantage of excellent prices and a quality guarantee.

Tablets for everyone

Not everyone likes taking tablets, but chewable vitamin brands can be costly. At Sealions, you spend the same on chewable vitamins as with capsules, so you won't have to worry about the kids.
