You can start with just the MetaPWR System but adding LLV has definite benefits.

The function of Lifelong Vitality and MetaPWR are quite different. They each address unique needs. You optimize your metabolism through macronutrients, curb cravings, shed excess weight, with MetaPWR but MetaPWR does not provide all the minerals and vitamins that your body needs to support function.* We know even the best diets are deficient in vital micronutrients. That’s where dōTERRA Lifelong Vitality Pack® (LLV) can fill the gaps.

Nutrition and metabolism have a synergistic effect on your health and overall wellness. While nutrition is the process of nutrient acquisition from your environment, metabolism is the chemical process your body uses to transform the food you eat into fuel. Studies have found persistent disturbance of nutrient metabolism or energy homeostasis—caused by either nutrient deficiency or excess—induces cellular stress, leading to metabolic dysregulation. If you are experiencing a vitamin deficiency, your metabolism is going to struggle.

Nutrition and metabolic support go hand in hand. They are the perfect health and vitality pairing.

PLUS, giving LLV a try is totally risk free! If you are not satisfied with the benefits of LLV, you can return the empty bottles to doTERRA within 45 days from purchase date, for a full refund of what you paid for LLV. So, there is really no risk in giving it a try!
