About Optimum Nutrition

Optimum Nutrition is the global standard for performance nutrition, founded in 1986 by two brothers with a passion for performance. Based in Downers Grove, Illinois, the brand became Glanbia's first billion-dollar brand, generating over $1 billion in retail value. Glanbia acquired Optimum Nutrition in 2008 for €213 million, having previously supplied whey for their products. Gold Standard 100% Whey is the world's best-selling protein powder, featuring whey protein isolate as the primary ingredient with 24g of high-quality, fast-absorbing protein per serving. The award-winning formula contains naturally occurring BCAAs and glutamine, is low in sugar and fat, and is Informed Choice certified for banned substance testing. Optimum Nutrition created the slowly digesting protein category with Gold Standard 100% Casein, providing 24g protein per serving for prolonged amino acid release overnight to support muscle growth while sleeping. They also created the anytime energy category, now dominated by Essential Amino Energy. Gold Standard 100% Isolate delivers 83% pure protein per serving through advanced filtration, with 25g whey protein isolate, 5.5g naturally occurring BCAAs, and 4.3g glutamine per serving - ultra-low in sugar (0.3g or less) and fat (0.4g or less). The Gold Standard BCAA Train + Sustain range offers 5g BCAAs in a 2:1:1 ratio plus Vitamin C and zinc for immunity support, designed for extended workouts with light, refreshing flavours. Additional products include Gold Standard Pre-Workout, Creatine Powder, HMB, Glutamine supplements, and protein bars including the Optimum Protein Bar and Protein Crisp Bar.

FAQs

Grocefully is a smart grocery shopping app that automatically compares prices across all major UK supermarkets (Tesco, ASDA, Sainsbury's, Morrisons, etc.) and helps you buy from the cheapest stores. We handle the complexity of split orders so you save money without any extra effort.

Our users save an average of 25-30% on their total grocery bill. For a typical £100 weekly shop, that's £20-25 in savings even after our 5% service fee. The exact amount depends on your shopping habits and the products you buy.

We currently support Tesco, ASDA, Sainsbury's, Morrisons, Waitrose, and Iceland. We're constantly adding new stores and will notify you when more become available.

Grocefully is available wherever the supported supermarkets deliver. Simply enter your postcode when you sign up to check availability in your area.

Our AI scans real-time prices from all supported supermarkets every time you shop. It finds exact matches or suitable alternatives for each item on your list, then automatically selects the cheapest option while considering delivery fees and minimum order requirements.

You can set brand preferences for any item. If you prefer specific brands, Grocefully will only compare prices for those brands. You can also allow substitutions for some items while keeping others fixed.

Grocefully shows you available delivery slots from each store and helps coordinate them. We optimize to get you the most convenient delivery times while maintaining the best prices.

Yes! You can link your loyalty cards from each supermarket and continue earning points on all your purchases. We'll automatically apply any available discounts.

We charge a simple 5% service fee on your total order value. For example, if your groceries cost £100, you'll pay £5 as a service fee. This covers our costs for finding you the best prices, handling multiple orders, and providing customer support.

Our users save an average of 25-30% per shop. Even after the 5% service fee, you're still saving 20-25% on average. For a £100 shop, you'd save £25-30 and pay £5 in fees, netting you £20-25 in savings!

The service fee is automatically calculated and shown before you complete your order. It's added to your total, so you only make one payment. No hidden charges or surprises.

Yes! Grocefully is completely free to download and use. You only pay the 5% service fee when you place an order. Browse, compare prices, and create shopping lists as much as you want without any charges.

No hidden fees! You pay the grocery prices (same as shopping directly), the stores' delivery fees (if any), and our 5% service fee. That's it. We believe in complete transparency.

If you're not happy with your savings, contact our support team. We'll review your order and if we didn't save you money (after accounting for our fee), we'll refund the service fee. Your satisfaction is our priority.

Yes, you can modify orders up until the supermarket's cut-off time (usually a few hours before delivery). Any changes are automatically synced across all your orders.

If an item is out of stock, we'll automatically find the next cheapest option from another store or suggest a suitable replacement. You can set preferences for how you want us to handle substitutions.

Refunds are processed according to each supermarket's policy. If you're not satisfied with your savings, contact our support team - we offer a money-back guarantee on our service fee.

Our customer support team is here to help resolve any issues. We work directly with the supermarkets to ensure quick resolution of any problems.
