NUTRITIONIST INSIGHT
With 10g of protein in just 63 calories, the M&S High Protein Shot is one of the most calorie-efficient protein sources available. The added magnesium supports muscle relaxation and recovery, making it ideal as a post-workout or mid-afternoon pick-me-up.
Myth Busters
MYTH #1: Protein Shots Are Just Marketing Gimmicks
TRUTH: Research shows that consuming 20g+ of protein post-exercise significantly stimulates muscle protein synthesis. A single protein shot provides 10g — half the optimal dose — in a convenient, low-calorie format ideal for on-the-go recovery.
MYTH #2: You Can Only Get Protein from Whole Foods
TRUTH: While whole foods are ideal, protein supplements are equally effective at stimulating muscle protein synthesis when protein quality and timing are matched. Protein shots offer convenience without excess calories, fat, or sugar.
MYTH #3: Protein Shots Will Make You Bulky
TRUTH: Gaining significant muscle mass requires sustained caloric surplus and progressive resistance training. At just 63 calories and 10g protein, a protein shot supports lean recovery without excess calories. It promotes toning and repair, not bulking.
MYTH #4: Protein Shots Spike Blood Sugar
TRUTH: With only 3g of carbs, the M&S High Protein Shot has minimal glycemic impact. In fact, whey protein consumed before meals can reduce postprandial blood glucose by 21% in type 2 diabetics by stimulating insulin release.
MYTH #5: All Protein Supplements Are the Same
TRUTH: Protein shots differ from shakes, bars, and powders in concentration and calorie density. The M&S shot delivers 10g protein per 100ml at 63 cal — far more concentrated than typical protein shakes (20-30g per 300-500ml at 150-250 cal).

Typical Glucose Response Curve

How to Optimize Blood Sugar Benefits
Consuming a whey protein shot 10 minutes before a meal slows glucose absorption and reduces blood sugar spikes:
- Pre-meal timing - Drink 10 minutes before a carb-heavy meal to blunt glucose response
- Post-workout window - Consume within 30 minutes after exercise for glycogen replenishment
- Mid-afternoon snack - Replace sugary snacks to avoid the 3pm energy crash
- Morning starter - Pair with breakfast to extend satiety through the morning
This pre-meal protein strategy helps maintain stable energy levels and reduces the need for insulin-spiking snacks.
