It is important to consult with a healthcare professional before using leucine supplements, especially for individuals with existing medical conditions.

What if your Leucine is low?

If your leucine levels are low, it may negatively impact muscle protein synthesis and repair. It's important to include leucine-rich foods in your diet such as chicken, fish, tofu, nuts, and seeds. Alternatively, you can also consider leucine supplements after consulting with a healthcare professional.
