Recharging your energy levels

Vitamin B12 is essential for energy production in the body. It plays a crucial role in the conversion of food into glucose, which is the primary source of fuel for the body's cells. 

When we have low levels of vitamin B12, our energy levels can plummet, and we may feel tired, weak, and sluggish. By supplementing with vitamin B12, we can increase our levels of this vital nutrient, leading to improved energy production and reduced fatigue. 

This can help us power through our busy days, enhance our physical performance, and feel more alert and focused overall. 

Whether you're an athlete looking to optimize your workouts or simply someone who wants to feel more energized, vitamin B12 is an excellent supplement to consider.

What Gives ActiveBurst the Edge?

Not all Vitamin B12 is equal. 

Most supplement companies use Cyanocobalamin: a synthetic form of vitamin B12 that’s cheaper to manufacture, but poorly absorbed by the body.

ActiveBurst Vitamin B12 uses Methylcobalamin. Methylcobalamin is the most functional form of B12 because it’s already in bioavailable form, so the body does not need to convert it in order to use it.

This means your body is getting the absolute most of the B12 you are taking.
