The Benefits of Vitamin D3 Supplements
Vitamin D is an essential nutrient needed for strong bones, muscular and immune health. It exists in two main forms - D2 (ergocalciferol) and D3 (cholecalciferol). Research shows vitamin D3 is the more potent, beneficial form for humans compared to D2.
Vitamin D3 has become a popular supplement due to its wide-ranging health perks. Here is an overview of why vitamin D3 deserves a place in your wellness routine.
Better Absorbed and Utilized
Studies demonstrate your body is able to absorb vitamin D3 more efficiently. D3 is also much better utilized for converting to the active form of vitamin D in the kidneys known as calcitriol.
Increases Calcium Absorption
Vitamin D3 is intimately tied to calcium; it enhances intestinal absorption of dietary calcium and supports calcium circulation in the bloodstream.
Supports Healthy Bones
By aiding calcium absorption, D3 helps deposit calcium into bones to optimize bone mineral density and protect against osteoporosis.
Facilitates Nerve and Muscle Function
Vitamin D receptors are present in the brain, muscles and central nervous system. D3 helps regulate levels of calcium and phosphorus needed for proper nerve and muscle activity.
Bolsters Immunity
D3 stimulates production of antimicrobial peptides that protect against pathogens. It also modulates immune cell activity to help prevent overactive inflammatory responses.
Given these broad benefits for skeletal, muscular, brain and immune function, vitamin D3 is a must for well-rounded health.
Top Vitamin D3-Rich Foods
While produced in the skin with sun exposure, you can also obtain vitamin D3 naturally through your diet. Here are some of the top food sources of D3:
Fatty Fish
Salmon, tuna, mackerel and sardines are among the best sources, with about 450-500 IU D3 in a 3-4 oz serving.
Egg Yolks
One scrambled egg yolk provides about 40 IU D3, along with protein and healthy fats.
Liver and Cod Liver Oil
Beef liver has lots of vitamin A and about 50 IU D3 per 3 oz. Cod liver oil is one of the richest sources, providing around 1,300 IU per tablespoon.
Fortified Dairy and Plant Milks
Cows milk, soy milk, almond milk and other plant-based milks are commonly fortified with 100 IU D3 per cup.
Mushrooms
Exposed to UV light, mushrooms generate substantial D3 with about 100 IU per 3 oz serving.
Fortified Yogurt, Cereal and Orange Juice
Check labels as these foods are sometimes fortified with 10-20% DV of vitamin D3 per serving.
A daily diet incorporating fish, eggs, dairy and mushrooms provides a tasty way to meet some of your vitamin D3 needs.
How Much Vitamin D3 Do You Need?
The recommended daily intakes for vitamin D are set at:
- 600 IU for ages 1 70
- 800 IU for over age 70
However, many experts argue for higher minimums of 1,000 2,000 IU daily for optimal health. Deficiency is common, especially in northern latitudes and winter when sunshine is limited.
Obese individuals, the elderly, exclusively breastfed infants and those with digestive disorders are also prone to vitamin D deficiency. Maximizing food sources may not provide sufficient vitamin D3 for these groups without supplements.
Signs and Symptoms of Vitamin D Deficiency
Some early indicators of suboptimal vitamin D levels to be aware of include:
Frequent Illnesses and Infections
Insufficient vitamin D hampers immunity, raising risk of frequent colds, flu and upper respiratory infections.
Bone Loss and Aches
Without adequate vitamin D, calcium absorption suffers, leading to accelerated bone loss and osteoporosis over time.
Chronic Pain
Widespread muscle and bone pain throughout the back, joints and limbs may signal deficiency.
Low Energy and Mood
Research links low D3 to fatigue, depression and mood disorders.
Impaired Wound Healing
Vitamin D stimulates production of compounds involved in wound repair. Poor healing can indicate deficiency.
Schedule a screening if you regularly experience several of these, along with risk factors for low D3.
Vitamin D3 Supplement Options
Given how often people fall short of optimal vitamin D levels, supplementation is encouraged by many health experts. Here is a look at the different types of D3 supplements available:
Capsules
Gel capsules with liquid vitamin D3 suspended in oil are readily absorbed and convenient for hitting targeted amounts.
Liquid Drops
Liquid D3 drops can be placed under the tongue or added to smoothies and drinks for supplementation without pills.
Gummies
As a tasty alternative, D3 gummies are available for kids and adults who dont like swallowing capsules.
Sprays
Oral vitamin D sprays provide liquid D3 that is sprayed into the mouth and absorbed through the mucous membranes.
For optimal absorption, always look for D3 (cholecalciferol) rather than D2 on supplement labels. Most provide 500 5,000 IU per serving.
FAQs
What's the difference between vitamin D2 and D3?
Vitamin D3 (cholecalciferol) is the form produced in the skin from sun exposure. Research shows it's more efficiently absorbed and utilized than D2 (ergocalciferol).
What are symptoms of vitamin D3 deficiency?
Common deficiency symptoms include frequent illness, bone/muscle pain, fatigue, mood issues and slow wound healing.
How much vitamin D3 per day is recommended?
600-800 IU daily is the standard recommendation, but many experts suggest 1,000-2,000 IU daily is optimal for most people.
What foods are high in vitamin D3?
Fatty fish, egg yolks, liver, fortified dairy/plant milks, mushrooms and cod liver oil are among the top food sources.
Should I take a vitamin D3 supplement?
Supplementation with liquid drops, capsules or gummies can help those at high risk for deficiency meet their daily vitamin D3 needs.
