Ingredients Label

Active Ingredients

Maltodextrin

Maltodextrin is the primary source of carbohydrates used in LBS.

It’s a low-cost carbohydrate, which is very fast-releasing (high-GI).

Organic Rice Bran and Peas

Both of these ingredients are much better sources of carbohydrates for a mass gainer.

They’re both slow-releasing (low-GI), and will have a smoother effect on blood sugar than maltodextrin.

Rice bran is also a great source of fibre, which is great for digestion and general health.

The ratios of the carbohydrates used isn’t disclosed, but their order on the label suggests that much more maltodextrin is used than these low-GI forms.

Whey Protein

Whey is the main protein that is found in cow’s milk.

Three forms of whey are used in this formula, which are absorbed at marginally different speeds.

Research on whey protein in general has shown it to significantly enhance the muscle growth and repair (1).

Who Takes It?

Athletes wanting assistance with gaining general weight and muscle mass will enjoy using Rule 1 LBS.

How to Take

Mix 2 scoops (275g) with 500-600mL water or milk, and consume as desired.

Side Effects

Excess protein consumption could worsen an existing kidney or liver condition.

Maltodextrin is a high-GI carbohydrate, and should be used with caution if you are diabetic or have issues with blood sugar levels.

Pros

Multiple carbohydrate sources, both low- and high-GI
A whopping 1030 calories per serving
Range of flavours to choose from

Cons

Too much maltodextrin for most people to have in one sitting (very high-GI)
Less protein per serve than other mass gainers

Conclusion

Rule 1 LBS is a very high-calorie mass gainer, designed to make it easy for you to gain muscle mass, no matter how much trouble you would usually have.

Although it will definitely help you gain weight, it only has 40g of protein per serving, which is on the lower end for a mass gainer of this serving size.

Despite having some low-GI carbohydrates and fibre, it is still predominantly maltodextrin-based, which is a very high-GI carb source.

You’ll want to avoid this product if you are diabetic.
