Weight loss is a combination of diet and exercise, but there are certain vitamins and supplements that can help accelerate the process. Natural Medicines, an independent group that analyzes research on supplements, states that there isn't enough reliable evidence to evaluate them. However, some vitamins and supplements can help boost metabolism, transport oxygen to cells, and reduce fat absorption. Vitamins B, D, iron and magnesium are 4 popular weight-loss supplements.
Vitamin B12 is important for energy metabolism and red blood cell production, which means it can help you lose weight by increasing metabolism and helping the transport of oxygen to cells. A study found that people with vitamin B12 deficiency lost more weight than those who weren't deficient. Vitamin A, vitamin D and calcium are important for women's health, and this supplement facilitates the recommended daily intake of each nutrient. Green tea is more than just a pleasant addition to meals in its liquid form; as an extract, it can also help you lose unwanted weight. Wittneben points out that there are also additional benefits associated with taking probiotics while dieting.
As weight decreases, strength usually increases. Orlistat, also known as Alli or Xenical, can reduce the amount of fat you absorb from food and help you lose weight. It has a lot of side effects, some of which are very unpleasant. Glucomannan can also make it difficult for the body to absorb medications. Therefore, take your medication 1 hour before or 4 hours after using glucomannan. Chitosan doesn't usually cause side effects, but some people have an upset stomach or constipation.
If you are allergic to shellfish, you should not take chitosan, because it is made from seafood. Because caffeine is believed to boost metabolism, companies often add it to commercial weight-loss supplements. Synephrine is a fairly powerful stimulant and is potentially effective for short-term weight loss. Fat burners are products that claim to help you reduce weight by boosting your metabolism and allowing you to burn more fat. However, dietary supplement manufacturers rarely conduct clinical trials. That's partly why there's little scientific evidence to show that weight-loss supplements work.
Until trial data are more available, claims about dietary supplements and weight loss should be treated with caution. If you're thinking about starting a vitamin regimen to help you lose weight, talk to your doctor first. Vitamins alone won't help much in promoting weight loss; lifestyle changes are the key to losing weight. A healthy diet and exercise will help you lose weight much more in the long term than vitamins alone.
