Optimum Nutrition Gold Standard Micellar Casein Protein Powder — Creamy Vanilla 3.86 lb, Slow-Release 24g Protein

Optimum Nutrition Gold Standard 100% Micellar Casein is a slow-release, creamy vanilla protein powder designed to deliver 24 g of protein per serving to support muscle maintenance and overnight recovery.

This micellar casein formula from Optimum Nutrition provides a steady supply of amino acids over several hours. Each 3.86 lb (approximately 4 lb) tub contains 53 servings, delivering 24 grams of protein and nearly 9 grams of naturally occurring essential amino acids per serving. The Creamy Vanilla flavor mixes smoothly in a shaker or blender and includes key minerals like zinc, magnesium and calcium to round out its nutrient profile.

How does micellar casein differ from whey for evening use?

Micellar casein forms a gel in the stomach that slows digestion, supplying amino acids to your bloodstream at a gentler pace than fast-absorbing whey. This slower release makes it a common choice for use between meals or before sleep when you want sustained protein availability. It’s not a complete substitute for whey post-workout but complements a training plan by reducing long fasting windows.

• 24 g protein per serving for sustained intake
• Nearly 9 g of naturally occurring essential amino acids
• Slow-release profile suitable for nighttime or between meals
• Includes zinc, magnesium and calcium

What is inside each tub and how many servings will I get?

Each container holds 3.86 lb (about 4 lb) of powder and provides roughly 53 servings. A standard serving supplies 24 grams of protein alongside naturally occurring essential amino acids and supportive minerals. Packaged size and label art may vary, but the nutrient content and serving count remain consistent.

• 3.86 lb container with approximately 53 servings

How should I prepare and use this casein powder?

The powder mixes easily with water, milk, or into smoothies using a shaker bottle or blender. For a quick nighttime drink, blend with water or milk; for a thicker treat, mix into yogurt or a smoothie bowl. Adjust liquid volume to control texture from thin shake to spoonable pudding.

• Ideal before bed or between meals to curb hunger
• Compatible with both water and dairy/non-dairy milks

Is this product suitable for my training goals?

Gold Standard Micellar Casein is designed for people who want steady protein delivery to help preserve muscle overnight or during long gaps between meals. It pairs well with daytime whey intake and a balanced training routine. While it supports recovery-related nutrition, it should be used alongside appropriate exercise, rest and a well-rounded diet.

• Complements pre- and post-workout nutrition strategies
• Useful for muscle maintenance during sleep or fasting
• Works with both strength and endurance training plans
• Part of a broader nutrition and recovery approach

Who is this for: This product suits athletes, gym-goers, and active adults seeking a reliable, slow-digesting protein source to help maintain muscle and manage hunger between meals or overnight. It’s appropriate for anyone looking for a creamy vanilla-flavored casein powder that mixes easily, provides a substantial 24 g protein serving, and includes essential minerals. If you prefer fast-acting whey immediately after training, consider pairing that with this micellar casein later in the day for a complementary protein strategy.
