ON Protein — shorthand for Optimum Nutrition protein — refers to the full lineup of whey proteins from the world's best-selling sports nutrition brand. In Singapore, ON protein powder is the benchmark against which all competitors are measured. Whether you want the classic Gold Standard Whey, the ultra-pure Hydro Whey, or a refreshing clear whey isolate protein water, there is an ON-level option for every fitness goal.
What Makes ON Protein the Gold Standard?
Optimum Nutrition has earned its reputation over decades by delivering consistent quality, third-party testing, and a wide flavour roster. The "ON" brand is trusted by competitive athletes across Singapore — from bodybuilders in Jurong gyms to marathon runners at East Coast Park.

Top ON Protein & Alternatives at Ultimate Sup Singapore
1. ON Platinum Hydro Whey — The Premium Pick
For those who want the fastest-absorbing ON protein available, the Optimum Nutrition Platinum Hydro Whey is the answer.
Using exclusively hydrolyzed whey isolate — with peptide bonds already pre-broken — Hydro Whey absorbs faster than any standard whey protein. Each serving delivers 30g of protein, 15.5g of EAAs, and 9.8g of BCAAs, with only 0.5g of fat. This is ideal for post-workout use when you want amino acids in the bloodstream as fast as possible. Popular among competitive athletes in Singapore who train twice a day.

2. MusclePharm Combat Protein Powder — The Multi-Source Alternative
If you prefer a protein that keeps you satiated for longer rather than absorbing instantly, MusclePharm Combat Protein Powder is the intelligent multi-phase alternative.
Combat blends five protein sources — whey isolate, whey concentrate, hydrolyzed whey, micellar casein, and egg albumin — providing both fast and slow-releasing amino acids. The result is sustained muscle protein synthesis across 2–8 hours, making it excellent as a meal replacement or a before-sleep protein shake. Each 35g scoop delivers 25g of protein. It is a trusted choice at gyms across Singapore from Tampines to Orchard Road.

If traditional thick shakes aren't your style — especially in Singapore's tropical heat — Myprotein Clear Whey Isolate transforms your protein supplement into a refreshing, juice-like drink.
This is a true protein water Singapore style product: it mixes translucently in water, tastes like a fruity sports drink, and delivers 20g of high-quality whey isolate with zero fat and less than 1g of sugar. Flavours like Tropical Dragonfruit and Bitter Lemon are incredibly refreshing after a run at Bishan Park or a session at Anytime Fitness. An excellent complement to your ON protein stack.
