The foundation under everything you just ordered: D3 + K2
One last thing before your confirmation. It’s the least exciting product in the lineup, and one of the most practical.
You’ve covered cellular energy with LX NMN+. If you added LX Creatine, you’ve covered strength and recovery. This last one is about the foundation underneath both: the basics your body needs to keep bones strong and your immune system working normally.*
Vitamin D: the gap most people have
Your skin makes vitamin D from sunlight, but long days indoors, winters and sunscreen mean many adults don’t get enough. Vitamin D helps your body absorb calcium and supports normal bone, muscle and immune function.[1]*
Why K2 comes with it
Vitamin D helps you absorb calcium. Vitamin K helps activate proteins involved in putting calcium into bone.[2] That’s why the two are so often paired: D to bring calcium in, K2 to help direct it where it belongs.*

Vitamin K2

Your training
The builder
Strength training is the signal that tells bone and muscle to stay strong.
