Designs for Health Carnitine Synergy - 400mg L-Carnitine (From Carnitine Tartrate) + 100mg Acetyl L-Carnitine Pills - Non-GMO + Vegetarian Supplement (120 Capsules)

designs for health

CA$114.14

More Details
Main highlights
- Vegetarians may need supplemental carnitine: L-carnitine occurs naturally in all foods, with animal proteins being the richest sources, especially red meat and dark meats, such as lamb, beef, and dark meat poultry. Minuscule amounts are present in plant foods
- Use fat as fuel: L-carnitine is an amino acid derivative used to help fat enter the mitochondria. Dietary fats and stored body fat are rich sources of energy, but require carnitine for transport to mitochondria. Simply put, without adequate carnitine, fat cannot be used as a fuel source in the body
- Desired form: Synergy carnitine exclusively combines L-carnitine and its acetylated form in one capsule in a 4:1 ratio
