Premier Protein vs Fairlife Core Power
These are the two bottles US shoppers compare most, especially people on Ozempic, Wegovy, Mounjaro or Zepbound who want protein they can drink when food is a struggle. Premier Protein is the grocery default: 30g of protein in 160 calories, 1g of sugar, sold everywhere. Fairlife Core Power is the smoother, milkier 26g bottle at 170 calories, made from ultra-filtered milk. On protein per calorie Premier wins; on taste a lot of people prefer Fairlife. Core Power sits 10 calories over the cap on our GLP-1 shake rankings, so Premier qualifies there and Core Power does not.

Ingredients worth noting
Premier Protein Protein Shake
- Seed Oils: Refined oils high in omega-6 linoleic acid.
- Cellulose Gum: Also called carboxymethylcellulose, a thickener.
- Carrageenan: A seaweed extract used to stop drinks separating.
- Caffeine: A stimulant, and ingredient lists rarely state the amount.
- High Oleic Oil: A seed oil from varieties bred so most of the fat is monounsaturated oleic acid, the same fat that dominates olive oil, with far less of the omega-6 linoleic acid that standard versions carry.
Fairlife Core Power
- Carrageenan: A seaweed extract used to stop drinks separating.
- Cellulose Gum: Also called carboxymethylcellulose, a thickener.
