Vitamin B12 for Athletes
Featuring sports nutrition expert Dr. Karen Martin on the benefits of vitamin B12 for athletes.
Feeling wiped out for no reason?
One of the most common culprits behind adult fatigue is anemia—and guess what often causes it? Low vitamin B12. It’s a small nutrient with a big impact on your energy, focus, and endurance.
Vitamin B12 has been getting a lot of love lately—and for good reason.
It’s a powerhouse for energy, focus, and recovery, and when it’s running low, your body feels it. That’s why so many high performers (and everyday go-getters) are leaning into B12 for both well-being and athletic edge. When your energy systems are firing, everything else tends to follow.
So, what’s behind the recent buzz?
Social media has helped B12 earn its “wonder vitamin” status—some swear by the lift in energy, others say it sharpens strength and endurance. As interest grows, there’s also been a rise in more aggressive approaches—shots, sprays, and supplements promising instant results. But here’s the truth: more isn’t always better. B12 is water-soluble, yes, but the body can only absorb so much at a time. Quality and consistency matter way more than megadoses.
