The principle of losing weight is simple: eat fewer calories than you burn. But in reality, the process is tough, and reaching a healthy weight takes time and dedication.

Eating a well-balanced diet is key, but a few safe supplements can give you an extra boost. They can work by speeding up your metabolism, helping your body to mobilize fat, give you more energy and focus so that you can better maintain a healthy lifestyle with good nutrition and a healthy exercise regime.

What Are The Best Vitamins For Weight Loss?

Good nutrition keeps your body working optimally which means includes healthy metabolism.

B Vitamins

The B vitamins include thiamine (vitamin B-1),  riboflavin (vitamin B-2), niacin (vitamin B-3), biotin (vitamin B-7), folate (vitamin B-9), and cobalamin (vitamin B-12).

These vitamins are essential to healthy metabolism and help your body to make use of energy stored in food. Which is why taking a B-complex vitamin can help you to feel energized and focused. (1) When your body is not metabolising macronutrients properly it makes loosing weight more difficult. Therefore a B-complex vitamin can also help you to loose weight.

B vitamins are found in milk, eggs, lentils, lean meat, potatoes, beans, and whole grains. However, b-12 is only found in animal products. Therefore, if you don’t eat animal products, then you should be supplementing.

Vitamin D

Vitamin D is critical to a positive mindset , energy production and healthy metabolism. Your body converts sunlight into vitamin D. However, people often do not get enough especially if they spend a lot of time indoors or live in climates with little sun.

For these people, supplementation is recommended. When it comes to fat loss, maintaining a good mood is integral. It will help you to stick to a healthy diet and keep you motivated.

In one 2011 study, overweight adults taking calcium and vitamin D supplements lost significantly more stomach fat than people not taking any supplements. (2) Although the role vitamin D plays in weight loss beyond improving mood and motivation, remains unclear.


Iron is a mineral that helps your body create energy from nutrients and carries oxygen to your cells, helping them burn fat. (3)

Iron is found in meat, shellfish, spinach, and beans, but is absorbed best from meat. Foods high in vitamin C, such as citrus fruit and tomatoes, can also help iron absorption. Women with heavy periods and people eating a plant-based diet are more prone to iron deficiency, for these people an iron supplement could be benfitial. 

However, too much iron can be dangerous. Therefore if you think you are at risk of iron deficit you should see your doctor and get a blood test before supplementing.


Magnesium is a mineral that plays a many important roles in the body, including regulating blood glucose and blood pressure, keeping bones healthy, and maintaining the nervous system. (4)

And yet magnesium deficiency is common in the United States. The best sources include nuts, seeds, and green leafy vegetables.

Try supplementing with magnesium and see how you feel. You may find that you have more energy, and you may find it easier to maintain healthy nutrition and exercise.

Herbal Remedies

Ensuring your body has all the nutrients it needs can make a big impact on your weight loss journey. Deficiencies are common, especially when you are eating less than your body needs or a restrictive diet.

Although herbal remedies are not essential to your body’s functioning, they can boost fat loss in several ways. Let’s look at some of the most effective herbal remedies:

Green tea Extract

Green tea can be a powerful weight-loss tool. It increases fat oxidization and energy expenditure and reduces fat production and absorption.

It is a powerful antioxidant is well known to increase metabolism. It is so effective that it has been shown to increase fat oxidization by 17%! (5) In other words, it helps your body to use more fat as fuel and therefore may help to burn it away.

Coleus Forskohlii

Coleus Forskohlii is a herb that has long been used in Ayurvedic medicine. It has been shown to move stored fat from cells, allowing it to be burned away by the body with more ease.  (6) When combined with a calorie deficit, this may boost your fat loss and even help you maintain muscle. 


Caffeine stimulates the central nervous system, which increases fat burning by up to 13%! (7).

Consuming 300mg of caffeine each day may allow you to burn an extra 79 calories. (8). That may not sound like much, but over time, it can have a big impact.

However, too much caffeine can have some negative side effects such as sleeplessness and anxiety, especially when taken later in the day. Sleep is integral to fat loss, so you should prioritize this first, and if you are sensitive to caffeine, it is not worth consuming it.


Chromium is an essential trace element that helps to regulate blood glucose, which can reduce food cravings. (9)

However, chromium is not absorbed well by the body. Therefore if you are considering supplementation, then you should look for more bioavailable forms such as Chromium Picolinate or GTF Chromium.

Capsimax Cayenne Pepper

Cayenne has thermogenic properties, which means that it raises your body temperature and, therefore, your metabolic rate, meaning that you burn more calories. (10) It also reduces hunger by inhibiting ghrelin, one of the hunger hormones (11).


Piperine, the active ingredient in black pepper, also has thermogenic properties. It has also been shown to prevent new fat cells from forming. (12)

Standard black pepper from your kitchen contains around 9% piperine. However, Bioperine, a trademarked form of black pepper, contains 95% piperine.


CBD is a non-psychoactive compound derived from cannabis. It has some incredible benefits, including improved sleep, stress reduction, and improved muscle recovery.

It may also help the body break down stubborn fat. Studies have shown that it can transform white adipose tissue – ‘bad fat,’ into brown adipose tissue – ‘good fat.’ Brown fat is labeled good because it contains high mitochondria levels, which takes more energy and therefore burns away more effectively. (13) Unlike its cousin, THC, it has even been shown to reduce appetite. (13)
