The B vitamins are essential water-soluble nutrients that must be consumed through food and supplements because the body cannot store them. All of the B vitamins, including B-12 and B-6, assist in converting carbohydrates from food into glucose fuel that is burned for energy. This helps increase metabolism in the body and may facilitate weight loss. Vitamin B-12 is also an important factor in red blood cell formation, nerve health and DNA synthesis. Vitamin B-6 plays a key role in balancing hormones and helping to metabolize dietary fats and proteins. Taking the recommended dosages of these vitamins can help facilitate weight loss and improve overall health.
Step 1
Talk to your doctor about your concerns regarding weight gain. Your doctor will determine if any health issues may be contributing to your weight gain. Ask your doctor about taking B vitamins to help with weight loss. Get a referral to a dietitian to help you outline a balanced diet plan that is also rich in B vitamins.
Step 2
Purchase vitamin B-12 and B-6 supplements. Read the labels carefully to ensure that you are not allergic to any of the ingredients. If you are diabetic, purchase vitamins that are made for individuals with diabetes.
Step 3
Consume the recommended dose of 2.4 mcg of vitamin B-12 and 1.3 to 1.7 mg of vitamin B-6 per day. If you have a nutrient deficiency of these vitamins, your doctor may recommend a higher dose. You may also require vitamin B-12 injections if you have a disorder that prevents absorption of this nutrient from the gastrointestinal tract. Swallow the supplements whole with a glass of water. It is best to take vitamin B-6 and B-12 with breakfast or early in the day because they may cause increased energy levels.
Step 4
Add foods that are high in vitamin B-12 to your diet. These include dairy and dairy products, fish, meat, poultry, eggs, nutritional yeast products and fortified cereals and breads.
Step 5
Eat more foods high in vitamin B-6. Sources of this nutrient include poultry, fish, organ meats, dairy products, brown rice, bran, wheat germ, sunflower seeds and green leafy vegetables.
Tips and Warnings
