Choosing the Best Vitamin D Supplements – Top 10 Brands

Best Vitamin D Supplement Brands

Vitamin D is vital for strong, healthy lives. Whether you’re a youngster just learning how to walk, a bodybuilder in his prime, or a retiree who likes to spend his days playing chess in the park, ensuring that you consume enough Vitamin D each day will help ensure you can keep doing what you love.

What Is Vitamin D?

Vitamin D is a fat-soluble vitamin [1] that, while required by the body for optimal health, is very difficult to get from diet alone. Supplementation, either in the form of fortified foods or the use of oral supplements, is commonly used to achieve sufficient levels of Vitamin D consumption.

It is a nutrient necessary for keeping the body’s blood levels of calcium and phosphorus steady. It also offers a variety of benefits, including increasing calcium absorption, decreasing fracture risk, and helping with diseases like osteoporosis or high blood pressure.

Although the body naturally produces vitamin D through the skin when exposed to sunlight, vitamin D deficiencies are quite common. Many medical professionals, including the Cleveland Clinic, recommend supplementation with vitamin D if your body’s vitamin D levels are deficient, for pregnant or breastfeeding women, for postmenopausal women, and for those with kidney or thyroid disease.

There have also been reports from regular users indicating that they experienced improvements in mood and energy levels while supplementing with D3.

Regardless of how you choose to consume your Vitamin D, it must also go through several stages of change within your body before it can be used effectively.

What Is Its Biological Role?

Vitamin D is a sort of side-kick in the vitamin world. Its purpose is to help your body properly absorb calcium. It also helps regulate calcium levels in the body once absorbed so that you have neither too little nor too much calcium.

Calcium is needed for the mending, growing, and maintaining of bones. It is, essentially, what makes them so strong. Without Vitamin D, your body would not be able to properly absorb calcium and use it to help keep you strong.     

What Foods Contain Vitamin D?

Vitamin D can be absorbed through skin during exposure to sunlight. Other than sunlight, the only other significant dietary sources are milk or other products that have been specifically fortified with Vitamin D, and oily fish such as swordfish, cod, or salmon.

How Does It Help Bodybuilders and People Who Work Out?

It is especially important for anyone who spends a lot of time working out to ensure that they consume enough Vitamin D.

Any fitness regime is going to put some amount of stress on your bones and muscles–this is doubly true for weightlifters and bodybuilders. Normally that wouldn’t be a problem, because sufficient amounts of Vitamin D help your body properly utilize calcium to keep your bones strong and prevent injury.

With insufficient Vitamin D consumption,[2] you greatly increase your risk of injury as a result of your fitness regime; without enough Vitamin D you lose calcium, and without enough calcium you end up with brittle bones that may break under the excess stresses of weight lifting or similar activities.

How Much Vitamin D Do You Need?

The recommended daily allowance of Vitamin D [3] is the same for all adults regardless of gender, or whether a new mother is pregnant or breastfeeding: 600 IU per day. For adults over 71 years of age, this recommended allowance is increased to 800 IU per day.

While it is not officially recommended for mothers to consume more Vitamin D when breastfeeding, increasing consumption may make the mother’s milk more rich in Vitamin D which can positively impact the child by helping to ensure proper bone formation as it grows.

Are There Risks Associated With Consuming Too Much Of It?

While unlikely due to its rarity from food sources, Vitamin D toxicity is possible when one consumes extreme doses of Vitamin D supplements. Vitamin D toxicity can result in hypercalcemia, which is an overabundance of calcium in the body that may start to negatively impact organs and veins.

It is worth noting that spending extended periods of time outside will not lead to Vitamin D toxicity, as the process that stimulates Vitamin D synthesis in reaction to sunlight is self-limiting. This means that after a certain threshold of production is reached, the sun starts to also break down the synthesized Vitamin D in a process called photo-degradation. This prevents your skin from producing harmful amount of Vitamin D while expose to direct sunlight.

Are There Risks Associated With Consuming Too Little Of It?

Without enough Vitamin D, your body cannot properly absorb and utilize calcium, which can results in rickets or osteomalacia in older adults. Rickets commonly affects children, and is a condition characterized by overly-soft bones as a result of Vitamin D deficiency which commonly results in skeletal deformities.

If rickets is caught soon enough, it is sometimes possible to reverse the effects with a therapeutically high dose of Vitamin D which can re-mineralize the bones since children are going through periods of near-constant growth for the first part of their life.

Taking Vitamin D

Vitamin D supplementation is a simple process. Most supplement brands recommend taking one supplement daily by mouth with a meal, although many supplement users report they do not experience stomach discomfort when taken without food.

Check the supplement you choose for their recommended serving size and dosing instructions. Be careful to follow the label directions exactly to prevent unnecessary risk. Vitamin D has some known medication interactions.

Certain medications can interfere with vitamin D absorption, including steroids, weight loss drugs, seizure medications, and some cholesterol-lowering drugs. Be careful if taking a vitamin D supplement if taking statin drugs or thiazide diuretics as these increase vitamin D levels.

Always speak with your doctor before taking any supplements.

Things to Look for in a Good Vitamin D Supplement

If you are looking to take a vitamin D supplement, it is important to choose a quality version that will meet your needs and allow you to reap the benefits of improved vitamin D levels. You should ensure the version you select meets your requirements. A good vitamin D supplement should also meet these minimum guidelines:

  • Be produced by a proven supplement brand – It is important to choose a supplement brand that has been proven to be safe and effective. Look for a brand that uses third-party, independent testing and uses quality ingredients.
  • Use the cholecalciferol D3 form of vitamin D – The D3 version has been shown to be closer to what your body produces naturally. D3 has been shown to be less toxic and better absorbed by the body. It outperforms D2 in most areas, and reliable sources like Medscape recommend health professionals encourage the use of the cholecalciferol form.
