This is what today’s article is going to do. We’re going to start with what these powerful nutrients do and why you should care…

The Role of Vitamins and Minerals in Your Body

what vitamins are good to help gain weight

Vitamins and minerals are the most important micronutrients. They’re called that because you don’t need as many. That doesn’t mean you can afford to ignore them, however.

While vitamins and minerals are not directly involved in the muscle-gain process or gaining weight, they’re indirectly important. Vitamins and minerals are tied into the processes surrounding other changes to the body. These adaptations rely on an environment in the body that micronutrients maintain.

When you have adequate vitamin and mineral intake, things are running normally. Not only does that make them important, but it means you need to watch out for deficiency. This is when you don’t have the required amount. It’s a quick route from deficiency to poor health – or poor results!

You don’t always get more benefits from more of a vitamin or mineral. Some have a minimum level, while some have an ‘optimal’ intake after which there are no major gains. What matters is understanding them 1-by-1 and being careful to give your body what it needs.

Before we discuss the best vitamins to gain weight, let’s see how your metabolism works:


One of the most important roles of vitamins and minerals – as they relate to weight gain – is metabolism. Your metabolism is about the uptake, storage, use, and balance of energy. Coincidentally, so is the weight-gain process.

When your metabolism is healthy, you have a clear control over the inputs and outputs in your body. Energy in and energy out have a stable relationship and you know you’re getting the best from food. Equally, you’re not sabotaging your energy production or use with a poor environment.

Maintaining the energy systems in your body means providing the energy and nutrients you need. This is obviously important since it’s how you turn exercise and diet into muscle and other tissues. Being up on your metabolic health means preventing unnecessary loss of results.

Many of the vitamins to gain weight that we’re going to discuss today interact with these. Metabolism is at the center of important nutrients like Magnesium, Zinc, and B vitamins.

Coenzyme Functions

Other aspects of vitamin and minerals in weight gain are as coenzymes. This means they’re part of the reactive process that helps your body control conversions, reactions, and the breakdown of chemicals. These are wide-ranging but almost always important for health and wellbeing.

Magnesium is number one for co-enzyme action, again. It has 100s of coenzyme roles – especially in hormonal and metabolic health – which gives it double importance on our list. Compounds that cross these lines and play multiple roles in your health and weight gain are extra important.

Preventing Deficiency Symptoms

Often, the idea of vitamins and minerals in these areas is simply to make sure you get enough. You don’t want to leave any doubt or uncertainty when it comes to your health. Metabolism, hormones, and immunity are all important areas for health and weight gain alike.

Proper vitamin and mineral intake – or at least concern – prevents major problems. Some areas require more focus, but otherwise it’s about taking care. Cover your bases, pay attention, and be ready to give some areas more attention where your weight gain is most affected.

Vitamins and Minerals for Weight Gain: Why Do They Matter?

vitamins to put on weight

Vitamins and minerals are important because they control all the processes we just outlined: hormones,  metabolism, and tissue-building. These determine the quantity and quality of your weight gain

The difference between a healthy and unhealthy metabolic environment is often a game of percentage points. Improving your vitamin and mineral intake may only show up as a few extra % weight gain. It may also represent a better % split between fat and muscle gain, preferring the latter.

What matters is that there are a number of important factors:

  •       Even a few % of extra weight is a great outcome
  •       Improving your fat-muscle gain even a few % is a huge improvement
  •       The health implications of vitamin and mineral deficiency are a major problem
  •       Micronutrient intake helps you support immunity and reduce lost training and recovery hours

There are a number of indirect methods. You’ll also find that vitamin and mineral intake contribute to better appetite. This helps with the natural development of muscle gain, as you get to eat more without just slopping calories from junk food sources.

You’ll also feel better throughout the day. Vitamin intake – and especially B and D vitamins – are great for energy levels and subjective wellbeing. Not only will you perform better and recover better, but feel better while you do it. There’s never a bad time to feel better.

Why Worry About Vitamins and Minerals?

Vitamins are powerful parts of your body’s natural processes - and deficiency comes with major weight gain limitations.

More people are vitamin deficient than they think. Effective vitamin and mineral intake comes from a diet that is rich in high-quality whole foods. As you might know, not many people maintain these healthy, nutrient-rich diets.

Most of us are either deficient or sub-optimal in some nutrients. The most common are Vitamin D and Magnesium, which are both crucially important to both health and function. We put ourselves at risk and we usually don’t even know it.

There are a laundry list of problems associated with deficiencies:

  •       Poor immune function and increased illness risk
  •       Reduced metabolic efficiency and health
  •       Compromised digestive health and wellbeing
  •       Major factor in limiting the effectiveness of weight control – as both gain and loss
  •       Can cause hormonal-metabolic problems and increase the risk of diabetes (e.g.)
  •       Deficiencies like iodine and chromium may contribute to thyroid illness
  •       Increased risk of cell damage, cancer, and liver or kidney diseases

These are just some of the risks and that’s even before considering performance. Athletic training and nutrition are built around avoiding these issues because they carry a host of problems. They typically reduce the quality of training and recovery, compromising both mental and physical performance.

Loss of appetite and effective nutrient-uptake are the two major factors of weight gain. They’re the result of poor hormone- and metabolism-regulating compounds. Weakness in B vitamin intake is the most common, with B1, B6, and B12 being especially important.

These can squash appetite, reduce the quality and quantity of nutrients absorbed from food, and compromise energy transfer. This means poor internal energy management and a limited scope for weight gain.

It’s as simple as not forgetting these compounds. Whether you’re motivated by gains or health, the best course of action is a diet rich in wholefoods – and especially plant foods.

Preventing Lost Results

One of the best ways to think about metabolic health with vitamins and minerals is as ‘leaks’.

Maybe the food you’re eating contains 3,000 calories. However, that doesn’t always mean you’re getting 3,000 calories of energy to your muscles and other tissues. When your metabolism is compromised, there’s a leak in the system.

Losing energy like this is common. The idea is that insufficiency, deficiency, and improper nutrition spring these leaks. They represent sub-optimal function. Why allow this to happen? If you’re going to be dedicated to protein intake and training, you should take vitamins and minerals seriously.

Quality of Weight Gain: What Are You Gaining?

If you’re vitamin deficient, you’re going to gain more fat and less muscle, or other quality weight.

There’s not just the question of plugging leaks and improving weight gain numbers. It’s also a major factor in nutrient partitioning. What are your calories and nutrients doing in the body? Are they going where you want, to improve muscle, connective tissues, and bones? Or are those calories becoming fat?

Better nutrient partitioning occurs when we exercise regularly and maintain a healthy metabolism. B vitamins, magnesium, zinc, and others are crucial here. They inform the partitioning of nutrients and pair perfectly with Protein and Carbs in the muscle protein signaling process.

Vitamin and Mineral Sources

One of the main problems for weight gain diets is that there’s usually a dilemma: do you eat higher-calorie foods, even if those tend to be less nutrient-dense?

Many of the most calorie-dense foods in people’s diets are unhealthy. Or, rather, they’re low in nutrients. If you’re limited by calories, that can be a major risk as you run out of “space” in your calorie allowance to get micronutrients in.

However, high calorie foods don’t need to be unhealthy. There are a range of foods that are both high in calories and rich in nutrients. Things like olives, avocados, cultured dairy, eggs, and offal are good examples.

High calorie foods can be rich in nutrients, while low calorie foods can be low in nutrients. What matters is that you aim towards the upper-mid and upper-right quadrants of these diets. When you’re in A, E, and B, you’re going to gain high-quality weight.

Eating high-quality plant and animal foods, dairy, seafood, and others are key. A good weight-gain diet gets protein, carbs, fats, vitamins, and minerals together. It prioritizes macronutrients and calories, but also provides vitamins and minerals in each meal.

The Best Vitamins to Gain Weight: What Should You Focus On?

vitamins that promote weight gain

The most important vitamins for weight gain are the B vitamins, vitamin C, and vitamin D. We’re going to look at the important roles they play and why you need them.

Thiamine (B1)

Thiamine – or B1 – is key for converting carbs into energy. This is important because carb-energy is one of the most important muscle protein signalers. By eating plenty of carbs, you tell your body that you have an abundance of short-term energy. This helps maximize muscle gains and supports better workout-to-workout performance and recovery. Looking for vitamins to put on weight? Don’t forget Vitamin B1.

Pyridoxine (Vitamin B6)

Pyridoxinevitamin B6 – is also key to releasing energy from food. It has 100s of roles in protein and amino acid digestion and use in the body. These are obviously important for maintaining your body’s amino acid levels and signaling for muscle gain.


Vitamin B12 is an essential fat and carb metabolism coenzyme, and one of the best vitamins to gain weight fast. It helps maintain the crucially important carb and fat energy systems – and their interactions. These are crucial for efficient metabolism. Some elite athletes even take B12 shots to maintain their metabolism and recovery – it’s that important.

The B vitamins as a whole are the most important vitamins for weight gain. They account for a number of the deficiency “leaks” mentioned above. Many people are deficient in B vitamins and suffer for it.

These are particularly common deficiencies among vegans and vegetarians. This is because animal products and dairy are typically the most easily-absorbed forms of B vitamins. You can also get them from high-quality nuts, seeds, and wholegrains.

Vitamin C

This is important: you don’t just gain muscle when you gain weight.

One key component of the weight you gain is connective tissue. These connective tissues are made of collagen (collagenous). Collagen is the most abundant protein in your body, and it makes up the tissues around muscles as well as tendons, ligaments, and bones.

When you gain weight, you need to gain non-muscle tissue, too! Vitamin C is important because it controls collagen synthesis in the body. This ensures that you’re giving all of your tissues the resources they need.

Collagen production associated with vitamin C is even more important because it’s the main protein in the body. As you gain weight, this is a major area for growth and proper vitamin C intake supports tendon health and the maintenance and repair of muscles.

Collagen is underrated – get your vitamin C from dark leafy greens, citrus fruits, and other high-quality wholefood sources.

Vitamin D

Vitamin D is the most common deficiency. Not only that, but the actual “recommended intake” is also very likely too low. While the optimal intake is around 2,500iu to 5,000iu, most people don’t get the required 750iu.

This is a serious limitation. Vitamin D is a major part of human health, with roles in neuroprotection, mental health and wellbeing, and hormonal regulation. These are major factors affecting your body and mind alike. These also interact with depression, anxiety, and immunity.

Aside from these huge health implications, hormonal balance with vitamin D is important for weight gain, making Vitamin D one of the best vitamins to help gain weight. Effective testosterone regulation and a role in the anabolic quartet (HGH, IGF-1, Insulin, and Testosterone) makes vitamin D very important.

It’s also found in high-quality foods like fish, seafood, and eggs. These are hallmarks of a good weight-gain diet so you should be thinking about your vitamin D intake as a responsible dieter, regardless of health benefits.

The Best Minerals for Weight Gain: What’s Most Important?

Minerals are very important for weight gain. The most important minerals for weight gain include magnesium, zinc, chromium, and iodine. These are related to the way your body regulates and builds new tissues. Healthy weight gain is about building high-quality muscle, protecting connective tissues, and supporting healthy metabolism - and minerals are key for all of them.


The ‘universal coenzyme’, Magnesium is important for 100s of processes. These are related to metabolism, hormonal health, and tissue repair. These make magnesium one of the most important compounds in any diet.

During weight gain, needs for magnesium are higher. It’s an essential electrolyte and offers a range of benefits including proper chemical balance in the muscles and elsewhere. It is key for neuromuscular health, which is basically the underlying system for muscle function, strength, and then growth.

Magnesium even plays into recovery processes aside from the muscles. It’s a key neural regulator in areas like sleep, while most people are deficient in this crucial nutrient. Once again, this is typically the case for vegetarians and vegans, due to the role of magnesium in animal foods.

You can get magnesium from wholegrains, nuts, seeds, and the aforementioned animal products. The intake of magnesium drastically improves health across a range of health markers. Their role in muscle growth and weight gain are impossible to miss or overstate.


Zinc is a controversial mineral that is an essential micronutrient in its own right. During younger age – perhaps up to 25 – it has a key role in growth. Zinc deficiency has been directly related to improper growth and hormonal dysfunction in young men and teenagers.

In adults, the role of zinc is something between metabolism and tissue growth. It has 100s of functions, many of which are metabolic in nature, and is another common deficiency. Zinc is particularly rich in nuts, seeds, and select wholegrains – which are often under-represented in diets.

Tissue growth and hormonal wellbeing are two cornerstones of weight gain. Effective muscle gain is a factor of both, and zinc needs to be a major consideration for your diet and supplementation.

Chromium and Iodine

Chromium and Iodine have related functions in the hormonal-metabolic pathways. They’re involved in the regulation of energy metabolism and the signaling for things like weight gain and loss.

Both are typically involved in weight loss. Research is clear: poor chromium and iodine intake negatively affect thyroid function. They’re key nutrients in maintaining metabolic health, and deficiency directly limits weight loss potential.

In the opposite direction, however, proper thyroid function is important for both health and weight gain. You need to maintain metabolic wellbeing throughout weight gain, where things like metabolic sensitivity, diabetes risk, and others are still present.

Good weight gain means maintaining the systems that allow you to function. Even when you’re not trying to lose weight, maintaining the thyroid is key to healthy weight control. There’s no point gaining weight at the cost of health and losing control over your fat and muscle gain/loss!

Minerals are also important, supporting a healthy energy environment and maintaining the processes around growth and recovery. These are behind high-quality, healthy weight gain as muscle and other useful tissues.

Are There Vitamins to Help Gain Weight?

Individual vitamins won’t help you gain weight, but they can contribute to better metabolism, performance, and recovery. This means they can indirectly benefit your weight gain potential and results.

The best vitamins for this are B1, B6, B12, C, and D. Then minerals like zinc and magnesium are great for supporting metabolism and growth.

What Vitamins Should I Take to Gain Weight?

You may want to take an all-purpose multivitamin, but individual vitamins also help. A vitamin B rich supplement is a great place to start. Most people also need more vitamin D, which is the most common deficiency or ‘insufficiency’ vulnerable nutrient.

You should also consider taking vitamin C to support joint recovery and health while performing heavy resistance training. This is a great way to maintain and support oft-neglected tissues and keep yourself healthy. Nothing ruins healthy weight gain like injury and time off.

What are the Best Vitamins to Take to Gain Weight?

You should prioritize vitamins B, C, and D. These are the main vitamin groups that boost metabolism and maintain hormonal health, as well as the quality of energy from food.

Further, you should consider supplementing key minerals like zinc and magnesium. You can also take additional iron, chromium, and iodine to maintain healthy hormone function while gaining weight.

Conclusion: Our Final Thoughts

what is the best vitamins to gain weight

High quality weight gain depends on getting the right vitamins for weight gain. Vitamins and minerals are key to supporting your body while it produces healthy weight gain results.

While you don’t have to be as strict on the balance of calories and nutrients as a weight loss diet, you should still pay attention. They’re key to both the healthy nature of your weight gain and the quality of that weight. When you put time into the details of your diet, you get more out. 

Proper vitamin and mineral intake are key to performance, health, and recovery between workouts. Controlling your diets controls your results. When you give them your time, you get results back in the shape of health and weight gain alike.
