Vitamin D receptors are found in just about every cell in the body—meaning D plays a big role in everything from bone, muscle, and immune health to cognition, mood, and, yes, longevity.* 

Research continually reiterates that vitamin D is a key player in many physiological processes tied to living a long, healthy, happy life.* Did we need another incredible benefit to convince us to take a vitamin D supplement? No. But we'll take as many longevity benefits as we can get.

Longevity benefits

In 2019, Biology published a review outlining the many longevity mechanisms and benefits of vitamin D. You may think of vitamin C when the term "antioxidant" is used, but vitamin C needs to spread the attention and love.

As it turns out, vitamin D is another essential vitamin that's a potent antioxidant, helping to balance mitochondrial activities, combat oxidative stress, and protect your DNA1—if your vitamin D status is sufficient, that is.* 

Without adequate levels of vitamin D, your body can't utilize the vitamin when it's needed for antioxidant actions or other vital activities.* 

When are vitamin D levels sufficient, though? The sunshine vitamin becomes a dynamic free-radical-fighting superhero among a team of antioxidant avengers.* 

Antioxidant benefits

Vitamin D signaling pathways are a key player in directly protecting cells from the overaccumulation of reactive oxygen species (ROS).* Specifically, vitamin D helps protect proteins (e.g., hormones, antibodies, collagen, etc.), fatty acids (aka lipids, like those in cell membranes throughout the body), and DNA from oxidation by combating oxidative stress.* 

Additionally, sufficient levels of vitamin D support mitochondrial resilience (you know, that energy powerhouse organelle in our cells) and endocrine functions.* This, in turn, promotes healthy energy metabolism, hormone activity and balance, and longevity.* 

Beyond the functions that foster antioxidant activity on a cellular level, here are some additional physiological systems that vitamin D supports to promote our overall well-being as we age:*

Vitamin D and aging

Vitamin D supports a long, happy, healthy life on multiple fronts—but only if you have sufficient levels of the essential vitamin, which requires daily planning.*

Considering it's absurdly difficult (read: basically impossible) to get enough vitamin D from food and sunshine alone, and our ability to maintain sufficient vitamin D levels becomes more challenging as we age, many individuals (younger and older) choose to add a high-quality D3 supplement to their daily routine.

The takeaway

For a comprehensive list of vitamin D supplements with researched back doses and clean ingredients, check out our vitamin D roundup.

But to cut to the chase, here's a little bit more about our top pick: with the most bioavailable form and effective dose of vitamin D (D3), plus an trio of avocado, olive, and flax oils for optimal absorption of fat-soluble D, mindbodygreen's vitamin D3 potency+ promotes healthy vitamin D levels to support oxidative stress balance and antioxidant activity, muscle health, cognitive function, bone health, and immune function through all stages of life.*

If you are pregnant, breastfeeding, or taking medications, consult with your doctor before starting a supplement routine. It is always optimal to consult with a health care provider when considering what supplements are right for you.
