Klean Isolate Natural Chocolate 20 g by Klean Athlete

If you train and want steady progress in lean mass, whey protein isolate is a simple way to hit an effective protein dose after lifting. It fits athletes targeting 0.3 g/kg protein per meal, adults who struggle to meet daily protein from food, and lactose‑sensitive people who tolerate isolate better than concentrate. Expect the biggest payoff when paired with resistance training and a total daily intake around 1.6–2.2 g/kg, with visible changes in 8–12 weeks.

Whey protein isolate digests quickly and delivers a high leucine content, the amino acid that triggers muscle protein synthesis (your body’s process of building new muscle) once a per-meal “threshold” is reached. A 20 g serving typically supplies about 2–2.5 g leucine, enough to flip that switch for many adults. Fast absorption makes it useful right after training, and the low lactose content reduces gut symptoms compared to whey concentrate for sensitive users.

Mix one scoop of Klean Isolate Natural Chocolate with 10–12 oz water or milk and drink within two hours after training, or use between meals to round out daily protein. Larger athletes often need 25–40 g protein post‑workout; if you’re over ~70 kg, consider 1.5–2 scoops or pair with food to reach ~0.3 g/kg. If you have another hard session the same day, add 20–40 g carbohydrate to help refill muscle glycogen (your stored fuel).

Avoid whey protein isolate if you have a milk protein allergy. If you have chronic kidney disease or are on a protein-restricted plan, talk to your clinician and track eGFR (kidney filtration) and Albumin/Creatinine Ratio (protein leakage in urine). Whey isn’t zero‑lactose, so if lactose triggers symptoms, test tolerance with a half serving. Phenylketonuria (a disorder of phenylalanine handling) is a contraindication due to the natural amino acid content.
