Unpacking the Link Between Vitamin D and Buffing Up
Think of vitamin D for athletes as a boss hormone that’s also a fat-soluble nutrient. You get it by soaking up rays, but you can also snag some from grub and extra pills.
1. How Vitamin D Pumps Your Muscle Protein Making
The body fixes and grows muscle after lifting weights through a process called muscle protein synthesis (MPS). Guess what? Research says that vitamin D is a boss at making MPS better because it turns on stuff inside our bodies that helps fix and grow muscles.
There’s this paper in the Journal of Strength and Conditioning Research that shows the buff athletes who get lots of vitamin D pack on more muscle strength and size than those not get enough of it. So, having the right amount of vitamin D seems to crank up the muscle-building power when you train.
2. Vitamin D for Athletes and Boosting Testosterone
Speaking of muscle, testosterone is pretty important for getting stronger, bigger, and bouncing back after a workout. There’s this connection doctors found between how much vitamin D you’ve got and how your body makes testosterone.
A study featured in Hormone and Metabolic Research noticed that dudes who popped vitamin D got a real boost in their testosterone levels. For muscle heads wanting to bulk up and cut down on time spent sore, keeping testosterone on point is necessary.
3. Vitamin D for Athletes and Bone Strength
You need tough bones for heavy lifts and dodging injuries. Vitamin D helps your body grab onto calcium, which you need for rock-hard bones and staying skeleton-strong. If you skimp on vitamin D, man, you’re playing with fire because your risk for tiny cracks in your bones and other bone hurts goes way up.

Types of Vitamin D: D2 vs. D3 and Their Effects
Not every type of vitamin D for athletes is the same. You’ve got vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol), and they’re the main ones in the pills and grub you get at the store. For folks pumping iron, getting the lowdown on what’s what can lead to wiser choices when they’re looking to up their vitamin game.
1. Vitamin D2 (Ergocalciferol)
- Source: This one’s in veggies (like shrooms getting some UV rays) and stuff that’s got extra vitamins added.
- Absorption & Effectiveness:
- It’s not as good at getting vitamin D levels up in your blood as D3 is.
- It doesn’t stick around in your body as long.
- It’s what doctors give you, but it’s not the top pick for athletes wanting to crush it.
2. Vitamin D3 (Cholecalciferol)
- Origin: Comes from animal-based foods like fish oil, egg yolks, and lanolin extracted from sheep’s fleece, and the skin makes it when it gets sun.
- Taking it in & How Well it Works:
- Beats D2 in being easier for the body to use and stronger.
- Keeps the vitamin D amount in the blood high and stable for longer.
- For muscle-makers and fitness junkies, it’s the go-to version.
Which Kind Should Muscle Builders Pick?
- For beefing up, getting stronger, and staying healthy, D3 takes the trophy.
- Research indicates D3 maximizes vitamin D levels way better, being up to 87% more effective (Journal of Clinical Endocrinology & Metabolism).
- Vegans should search for lichen-derived D3, the plant-based option instead of lanolin-sourced D3.
Vitamin D Deficiency in Bodybuilders
Even though it’s super important, a bunch of bodybuilders and folks who work out a lot don’t have enough vitamin D. Here’s why:
- Indoor Workouts: Loads of muscle heads lift weights inside where the sun’s rays can’t reach.
- Slathering on Sunscreen: Sure, sunscreen keeps skin cancer away, but it also stops UVB rays, and you need those for making vitamin D.
- Vitamin D Sources: Not many foods have a lot of vitamin D in them.
Signs You Might Lack Vitamin D
- You feel tired or weak
- You take a while to bounce back after exercise
- Your muscles ache, or your joints hurt
- You’re not as strong or efficient in your performance
Getting a blood test is the way to know your vitamin D levels if you’ve got these issues. Athletes often need their levels to be from 50-80 ng/mL.
Boosting your Vitamin D for Muscle Building
1. Catching some Rays
To get a dose of vitamin D for athletes naturally, you should soak up direct sunlight. Try catching 10-30 minutes of midday sun a few times every week, but this depends on where you live and your skin color.
2. Vitamin D-Rich Foods
Not a ton of foods have loads of vitamin D, but if you want to score some, here’s where you can find it:
- Oily fish like salmon, mackerel, and sardines
- The yolk part of eggs
- Milk that’s got extra vitamin D tossed in, whether it’s from a cow or made from plants
3. Supplementation
Athletes who hang out indoors for their training or those who live in places where sunshine is like a rare treasure, taking some vitamin D3 supplements can do wonders. There’s a bunch of advice on how much you should take, but a lot of smart folks reckon:
Take 1,000 to 5,000 IU each day to keep up.
If you’re low on vitamin D, you might need up to 10,000 IU for a bit.
But hey, talk to your doctor before you start gulping down a bunch.

Conclusion
Vitamin D for athletes kicks things up a notch for muscle builders. This stuff plays a huge part in making muscles bigger, getting stronger, pumping up testosterone, and keeping bones tough.
