12 Best Vitamin D3 Supplements of 2022

By Dr Frank Yap, MD -

In recent weeks and months, several publications and studies have suggested that maintaining adequate levels of vitamin D would seem potentially beneficial in fighting the COVID-19 infection.

How do you know that your vitamin D level is adequate? Most people in the United States consume less than recommended amounts of vitamin D. 

An analysis of data from the 2015–2016 National Health and Nutrition Examination Survey (NHANES) found that average daily vitamin D intakes from foods and beverages were 5.1 mcg (204 IU) in men, 4.2 mcg (168 IU) in women, and 4.9 mcg (196 IU) in children aged 2–19 years (NHANES).

What Is Vitamin D?

Vitamin D is a fat-soluble vitamin, meaning that it dissolves in fats and oils and can be stored in your body for a long time.

Two main dietary forms exist (Am J Clin Nutr. 2012):
  • Vitamin D3 (cholecalciferol). Found in some animal foods, like fatty fish and egg yolks.
  • Vitamin D2 (ergocalciferol). Found in some plants, mushrooms, and yeasts.

What is Vitamin D Good For?

Vitamin D helps keep you bones strong by aiding in the absorption of calcium and phosphorus. It's involved in maintaining a healthy immune system, mood regulation, heart health, and even weight loss. 


What is the Best Form of Vitamin D?

Of the two, D3 (cholecalciferol) seems to be almost twice as effective at increasing blood levels of vitamin D as D2 (ergocalciferol) (Trusted Source, Trusted Source).

Several publications and studies have suggested that maintaining adequate levels of vitamin D would seem potentially beneficial in fighting the COVID-19 infection.


What is the Best Strength of Vitamin D to Take?

How much vitamin D3 is recommended? Consuming 400–800 IU (10–20 mcg) of vitamin D should meet the needs of 97–98% of healthy people. However, several studies show that taking more than this is linked to greater health benefits.

These research implies that consuming 1,000–4,000 IU (25–100 mcg) of vitamin D daily should be ideal for most people to reach healthy vitamin D blood levels.

However, don’t consume more than 4,000 IU of vitamin D without your doctor’s permission. It exceeds the safe upper limits of intake and is not linked to more health benefits

You need to take them with a meal, real food. Not a light breakfast or a snack. Maybe other vitamins you can get away with that, but these are packed with almost everything you need and more.

What is the Best Vitamin D Foods?

Here is the vitamin D3 content of a few of the best food sources (nih.gov):
  • Salmon, cooked, 3 ounces (85 grams) 447 IU / 11 mcg (75% of RDI)
  • Tuna, canned in water, 3 ounces (85 grams) 154 IU / 4 mcg (26% of RDI)
  • Beef liver, cooked, 3 ounces (85 grams) 42 IU / 1 mcg (7% of RDI)
  • 1 large whole egg (D is found in yolk) 41 IU / 1 mcg (7% of RDI)
  • 1 sardine, canned in oil, drained 23 IU / 0.6 mcg (4% of RDI)
Although fatty fish like salmon, mackerel, swordfish, trout, tuna, and sardines are decent sources, you would have to eat them almost every day to get enough.

The only excellent dietary source of vitamin D is fish liver oil — such as cod liver oil — which contains upwards of two times the Reference Daily Intake (RDI) in a single tablespoon (15 ml).

Keep in mind that dairy products and cereals are often fortified with vitamin D (Source).

Some rare mushrooms also harbor vitamin D, and egg yolks contain small amounts.

Best Vitamin D Supplement for Absorption

Vitamin D is a fat-soluble vitamin, meaning that it does not dissolve in water and is absorbed best in your bloodstream when paired with high-fat foods.

For this reason, it’s recommended to take vitamin D supplements with a meal to enhance absorption.

According to one study in 17 people, taking vitamin D with the largest meal of the day increased vitamin D blood levels by about 50% after just 2–3 months (NIH).

In another study in 50 older adults, consuming vitamin D alongside a fat-heavy meal increased vitamin D blood levels by 32% after 12 hours compared to a fat-free meal (NIH).

Avocados, nuts, seeds, full-fat dairy products and eggs are nutritious sources of fat that help boost your vitamin D absorption.

What Does Vitamin D Do For Males?

Vitamin D is essential for muscle development as it is involved in the development of skeletal muscle.

Vitamin D also plays an essential role in men’s sexual function and testosterone levels. Healthy levels of vitamin D may also benefit sexual health by mitigating the risk of cardiovascular disease.

Does Vitamin D Help Lose Belly Fat?

Yes, Vitamin D can help trigger weight loss primarily in the belly. This is because Vitamin D and Calcium may work synergistically to reduce the production of cortisol, which is a stress hormone that causes you to store belly fat.

Vitamin D for Acne

Acne is a common and complex skin disorder that can be stressful for many patients due to its chronicity. Although acne is caused by a number of factors, but chronic inflammation is an important mechanism.

According to a study, vitamin D has an immune regulatory function in sebocytes, implying that vitamin D may have anti-inflammatory properties in acne patients.

Vitamin D for Skin Health

Apart from its role in maintaining bone health, vitamin D also has a role in maintaining skin health. 

Vitamin D for Dry or Itchy Skin
Severe dryness of the skin or Itchy skin can be an indicator of Vitamin D deficiency. Getting enough Vitamin D can improve symptoms of skin disorders that cause dry, itchy skin.

Vitamin D and Psoriasis
Nutritionists are particularly interested in vitamin D supplementation for these two reasons. First, oral vitamin D supplementation is an important supplementary therapeutic choice for psoriatic patients. Second, vitamin D supplementation may be crucial in preventing psoriasis-related comorbidity, hypertension, and metabolic syndrome.

Vitamin D and Vitiligo
According to one study, high-dose vitamin D therapy may be both safe and beneficial in the treatment of vitiligo. Sixteen vitiligo patients with low vitamin D status were given 35,000 IU per day for six months, along with a dairy and calcium-rich food limitation and minimum hydration of 2.5 L per day. And the outcome, fourteen of them had re-pigmentation ranging from 25 to 75%. It’s still uncertain if high-dose supplementation provides any benefits for long-term patients with vitiligo.

Vitamin D and Atopic Dermatitis
Vitamin D may play a role in improving the symptoms of Atopic Dermatitis. The findings of this study imply that vitamin D supplementation may help reduce the severity of atopic dermatitis and can be considered as safe and manageable treatment option. However, this conclusion still needs larger-scale studies over a longer duration of treatment.

A cosmeceutical is essentially a skincare product that contains a biologically active compound that is thought to have pharmaceutical effects on the skin. Both pharmaceutical and cosmeceutical grade skin care products actively effect skin at a cellular level, whereas cosmetic products have a shorter-term effect. They are usually used by doctors to restore pH, remove pigmentation, or restore the skin barrier. Cosmeceuticals must scientifically verify the claims stated on their packaging; as it is accepted that these formulations are backed by science, clinical studies, and rigorous testing. The main areas of concerns that these formulations address are ageing skin, sensitive/sensitized skin, sun damaged skin, acne/oily skin, loss of tone and elasticity, as well as superficial lines & wrinkles to encourage rapid cellular turnover that will renew and re-texturize the skin.

Exosomes, neurocosmetics, and supercharged actives are the most innovative — and sometimes the most controversial — skin-care trends poised to revolutionize beauty in the next few years. We pored over the data and talked with experts to give you a snapshot of the top skin-care trends of 2024. Regenerative medicine will inspire your skin care. This year skin care won’t focus solely on addressing the signs of aging; it’s going to try to make cells behave younger, says Steven Cohen , MD, a board-certified plastic surgeon in San Diego.

The Fenbendazole Cancer Protocol has been gaining rapid interest over the past years following some fenbendazole advanced cancer success stories.
