Just before we answer ‘what is the best and cheapest whey protein powder?’, we’re going to briefly explain what it is and other questions that you may have!
What is cheap whey protein?
Whey protein is a protein isolated from whey. It is the liquid part of milk which separates during cheese production. Not only is it typically quite cheap if you shop around as you'll see from our list of products below, but it is also a really effective way of boosting your daily protein intake in no time at all.
When you buy whey protein for cheaper it doesn’t necessarily mean that you are buying a lesser grade product; some companies simply buy protein in bulk to make it cheaper to sell on to their customers.
If you take a look online, the competition for selling protein is high and that’s why some companies decide to make their protein cheaper, as they are able to make their product more appealing to potential customers.
Cheap VS Expensive Protein Powder
Before we get into our list of the cheapest whey protein powders, we’re going to briefly discuss the pros and cons of both cheap and expensive protein powder!
Pros of Buying Cheap Whey Protein
Whenever you’re looking to buy whey protein online, cost always plays a part in deciding whether or not you should go for a particular option.
If you use protein powder regularly, it only makes sense that you’ll want to look for a cheaper alternative. And if there are cheap whey protein powders out there that are just as good as the more expensive options, why would you spend the extra money?
The only issue with this approach is that finding the balance between cost and quality is tough without trying out tons of different products.
One way to ensure a cost effective approach to buying decent protein is to buy in bulk at a discounted price. Or, you can check out our reviews just below to find our favourite cheap but high-quality whey protein products!
As we briefly mentioned above, buying cheap whey protein in bulk is typically much more cost effective than buying smaller packets as it drives down the price per serving.
Thanks to the fact that protein powder is such a dry substance, buying in bulk really isn’t an issue as long as you use your protein powder within 6 months of opening it.
Not only does buying whey protein powder in bulk reduce the cost per 100 grams, but buying a larger tub of protein means less frequent online purchases and fewer trips to the shops. This will help you to save money and even save on the delivery costs of your protein!
Cons of Buying Whey Protein for Cheap
Sometimes when you buy whey protein online for cheap, some ingredients will not help you in terms of your fitness goals.
If you’re using the protein to gain muscle mass or lose weight, you should be aware that some cheap protein powders may include artificial sugars or flavourings to disguise the taste of a poor quality product.
Now that we’ve discussed the pros and cons of buying a cheaper whey protein, let’s move on to discuss the pros and cons of buying expensive protein.
Poor quality raw ingredients
Often when you come across cheap whey protein powders, you will see 'whey concentrate' on the ingredients list instead of the more expensive 'whey isolate'.
Whey protein concentrate costs far less to produce in comparison to whey isolate. This is because there are more steps to extract whey isolate from milk and thus, the cost is far higher.
Therefore, some protein companies will offer a blend of both whey concentrate and whey isolate to keep costs down.
Low content of protein
Not all protein powders will have the same amount of protein per serving. More expensive whey protein may contain a higher percentage of between 70-90% of protein per serving.
Whereas, cheap protein powders may use as little as 30-40% of protein per serving.
There will be a higher content of carbohydrates and fats with filler ingredients such as thickening agents to bulk up the shake and keep costs down.
Pros of Expensive Protein Powders
Buying a more expensive protein powder may mean that the product is made of ingredients like whey isolate or made with organic ingredients which are far more effective than some cheaper alternatives.
Protein is, of course, the main ingredient in the powder and most cases, the type of protein the brand will use will be of higher quality and will correlate with how efficient the protein powder will be in absorption rates.
When a protein powder is expensive, the company will want to make sure the product is top of the range.
If a company is going to sell a product at a premium price, they will want to assure their customers that it’s worth the money.
Therefore, the protein will undergo rigorous testing with scientist providing evidence to prove the protein powder will be the best on the market.
Cons of Expensive Protein
Not cost effective
Just because the protein is more expensive, it doesn’t mean it is the best. Several protein companies tend to claim a range of benefits to entice you to purchase their protein.
You should carry out further research and see if buying the expensive protein will benefit you and your fitness goals. If you could get the same results from cheaper whey protein, why wouldn’t you go for the cheaper alternative?
Now that we’ve explained what it is, let us find out where to buy cheap whey protein!
