Factors to Consider Before Buying Weight Gain Supplements

Taking a weight gain supplement isn’t just about getting in a healthy weight range, in fact, many use a weight gain supplement to help them in the gym when it comes to strength training and making themselves bulkier. We aren’t talking about your standard pre-workout, we’re talking about a supplement that will allow you to healthily gain weight without the use of fatty foods and bad calories. There are a ton of things you should know before purchasing your very first or another type of weight gain supplement.

Research more about a supplement – when it comes to something as drastic as a weight gain supplement, researching and knowing more about a supplement, what it does, and how your diet changes is imperative. Those that are new to the game may not realize that a weight gain supplement is extremely high in calories, and allows you to hit your calorie goals much easier day in and day out. With that being said, if you want to eat massive burgers every day with no healthy foods in between, and think that this is a safe option, you’re going to be gaining a ton of fat to say the least – and not any healthy weight, either. You’ll want to edit your diet and see what’s best before you dive into taking weight gain supplements.

There are some that are considered a “hard gainer”, also known as someone who eats and eats and eats, in order to try and get their weight up, a weight gain supplement may be a great decision for you, but you’ll have to edit your diet and nutrition to make it fit with your lifestyle. If you’re someone that requires thousands of calories per day to meet your personal goals, there are very high calorie shakes provided by certain weight gain supplement companies.

Stay lean, don’t get fat – with the right diet and a weight gain supplement that’s specially formulated, you’ll be able to get leaner, rather than gain fat. One of the biggest things about using a weight gain supplement to meet calorie goals is that you don’t want a heavy amount of fat, which can compromise your immune system and organs. You’ll basically want this supplement to aid your muscle-mass building with the right type of dietary fat. Because of this, you’ll want to make sure that there are little to no saturated fats within your weight gain supplement, as well as medium chain triglycerides, or else you may be worrying about putting on actual fat, rather than lean weight.

Find when you should take a weight gain supplement – not all weight gain supplements are meant to be taken close to the time of your workout; in fact, there are some that are meant to be taken afterwards, and can be taken as meal replacements so you’re not overreaching for calories that you don’t need. You can also have some that are meant to be taken with your food as an additional calorie supplement. Whatever your intention, make sure to research each weight gain supplement you come across, or else you may be taking it wrong and not yielding the best results.

Those that want to take their weight gain supplement right before or right after their workout should look for a recipe or blend that contains little to no fat, and one that has a high carb count. When you have this blend together, you find that you’ll be able to meet calorie goals without splurging or without lean properties. It’s worth noting that the best time to take a weight gain supplement is when you are starting your workout or when you are finishing, as your muscles will act with the carbs in order to transport the amino acids properly to your muscle’s cells. When this happens, the calories are being successfully used to help make you leaner and bulk up, rather than gain actual fat. We highly suggest trying on that you’re meant to take after your workout.

Look at the calorie levels – just because they’re meant to be higher in calorie values than other products, doesn’t mean you should skip out on knowing how many are in each. With weight gain supplements, the calorie levels vary greatly, and you should never skimp out on them. Because of the varying levels of calories, the product will help build your muscles in a specific way. You’ll want to match the perfect weight gain supplement calorie level with your nutrition level and your muscle needs.

If you’re someone that struggles greatly with building any sort of muscle mass, then a weight gain supplement that is higher in calories will serve you well. Those that build easily, but need an extra boost, don’t have to go as high as others. There are some that are well over 1000 calories per serving, and others that are in the 400-500 range. Make sure to research and create a plan that works for you.

Creatine matters – another reason you should research more on the ingredients and the product itself is so that you can meet your creatine levels much easier. With a weight gain supplement, you’ll be able to hit multiple birds with one rock. You won’t need an extra protein shake or powder when you have a product that not only fuels your muscles, but gives you the extra ingredients that you need. Make sure your weight gain supplement comes with creatine to top off the success of the weight gain supplement. Of course, there may be water weight at first, but this is only because of the extra influx of carbs that your body is seeing.

After some time, you’ll see this water weight flow off, and you’ll start to gain lean mass. Timeframe: one to two weeks. If this is your first time working out in a long time, and you’re coupling this with a weight gain supplement, you may not see this water weight come off for as little as three weeks because of the workout impact to your muscles. When you first start working out sort-of heavily, the tears in your muscles fill with water to protect them.

You’ll be able to recover faster – thanks to the inclusion of l-glutamine in many weight gain supplements; you’ll be able to recover much faster than you normally would. This is usually because of the l-glutamine that’s included in the recipe list. There are many products that come with this and act as a double-duty product, so not only are you getting creatine, but you’re also getting l-glutamine for recovery. This is a type of amino acid that ensures your muscles are going to be recovering as best as possible. Those that tend to be sore or take longer to recover after workouts may want to look into this ingredient when searching for the best weight gain supplements on the market.

Furthermore, the usage of l-glutamine in your weight gain supplement will ensure a healthy and ready-to-go immune system. In doing so, you won’t have to miss out on important training sessions and workouts because you feel ill or because you mysteriously got sick. Don’t compromise your immune system because of a flaky product – it’s not all about aesthetics.

Tips for Choosing the Best Weight Gain Supplements for Your Needs

You may know a weight gain supplement as a protein shake – in more modern terms. If you’re looking for the best protein shake or weight gain supplement on the market, there are a few things more that you’ll need to know and define before purchasing. So, how do you know which protein powder or weight gain supplement is the best for you?

First and foremost, you should know the importance of a protein powder versus a whole food or weight gain supplement. Even though you can meet your protein and calorie goals with food, sometimes for those that are bulking up incredibly, it may just be too much to eat that amount every day. With a protein powder or other type of weight gain supplement, you’ll be able to take a much smaller amount, receive the proper calorie or protein amount, and not worry about getting sick from feeling too full. You should aim to get your daily nutrition from food, while using a weight gain supplement to fill the calorie void.

The right ingredients – when choosing the best weight gain supplement, you’ll want one that comes with a variety of extra ingredients. Some of these ingredients include l-glutamine for recovery, as well as creatine so that you’ll be able to fuel your muscles and reduce the need for post-workout shakes or another product to help your fitness routine.

The types of proteins – yes, there are different types of proteins that you should know, and you should also know their best uses. The types of proteins include the following:

  • Egg protein – this type of protein is way slower than whey, and you can usually take this type of protein throughout the day
  • Milk proteins – a perfect protein for supporting your immune function, you’ll be able to enhance the growth of your muscles much easier with this product
  • Rice protein – for those that are vegetarian or vegan, this is a 100% plant-based protein
  • Pea protein – typically, a pea protein is hypoallergenic, and is very digestible
  • Hemp protein – naturally, this is also a 100% plant-based protein

If you want to build your muscles and get lean muscle mass, you should look for a protein powder that has a value known as “high biological”. If you’re this person, you should look towards whey isolate or a whey protein in general for the best results.

While weight gain supplements make take inspiration from these types of proteins, you may not see a company directly label one as an egg protein, milk protein, etc., but you’re free to research more on the aforementioned to help you gain weight in the gym and speed up your recovery.
