7 Natural Weight Loss Supplements With Scientific Evidence

Looking for the right information on the internet can really daunting at times. If you ever had to go through this, you will understand the feeling that follows when you finally stumble across the right information. It feels like you'd won a battle. 

That was how I felt when I found mine. You could find yours too, searching through the natural products archive because you see, our bodies function and react differently to different products and that was why I saw it fit to write this post. 

Listed below are 7 effective supplements (I have tried 1, 2, 3 and 5) with scientific studies giving proof to their weight loss benefits. 

Note. Some of them have side effects. Consult with a physician before attempting any one of them especially if you are on medication or have any health issue.

75% of new and old supplements were found and made in the United States so, I dug through the websites of the U.S National Library of Medicine for old and new research on supplements and read through journals and articles of prominent researchers and nutritionists. These supplements have been graded A or B according to their Natural standard for supporting weight loss. 

1. Garcinia cambogia, Hydroxycitric Acid (HCA) 

In a previous post,  I reviewed Garcinia cambogia and how it could be used for weight loss.

The different researches made use of different brands of Garcinia cambogia or HCA and as would likely occur, came out with varying results but it was observed that the higher the amount of HCA, the more significant the weight loss therefore, the recommended dosage for significant weight loss is 60% to 80% of HCA.

2.  African mango Extract 

It's a bit surprising that something so common to this part of our world could possess weight loss capabilities that we don't know about. Thank God for western research. African mango extract scientifically known as Irvengia gabonensis is gotten from the seed of 'Bush magoes' popularly known
as 'ogbono' in Nigeria and 'Dika' in Cameron.

When taken right and with the right dosage, this dietary extract, according to research could help in weight loss, cholesterol reduction, and diabetes. The peculiar thing about this supplement is that it takes 4weeks for you to see significant changes but research is still ongoing as more is being discovered.

3.  Glucomannan 

I did a review on Glucomannan when I was writing a post on SkinnyFiber dietary Supplement. This dietary supplement come in capsule, tab and powder form and have lots of positive reviews. its most praised feature is it's ability to help with controlling blood sugar levels and curbing the appetite.

The beauty of this water based dietary extract is that it is a very nice thickening agent and can be added to soups and stews and for baking or frying.

4.  Conjugated Linoleic Acid or  CLA

CLA is a natural occurring Omega 3 fatty acids and healthy fats that can be found in diary products and meat. Years ago,  it was found that CLA could promote lean muscles, prevent cancer and help in reducing body fat.

Flax seeds - A Source of Omega 3 fatty acid

Several clinical trials have produced varying results. In one study done by Chih-Kun Huang, MD, from the I-Shou University, on an obese Chinese, he observed after over twelve weeks of supplementation of CLA that it produced a 0.6kg decrease in total body weight.

“The consumption of milk supplemented with CLA (3.4 g/d for 12 wk) significantly decreased the body weight, BMI, body fat mass, fat percentage, subcutaneous fat mass, and waist-to-hip ratio in overweight and grade 1 obese subjects." he said

CLA can be found in capsule and syrup form and in varying degrees of concentration. According to a researcher,  Jean-Michel Gaullier, PhD,  consumers should ensure they purchase a product containing 80% of CLA.

5.  Whey Protein

You must have heard about Whey protein. It is usually in powder form, shakes or as the major ingredient in a protein bar. Whey protein is gotten from the whey of milk.

It contains a high amount of amino cysteine, is packed full of fiber and is easily digestible. Sports, health and bodybuilding persons absolutely love whey protein as it suppresses the appetite, promote muscle building,  repairs cell tissues and promotes weight loss.

6.  Chitosan

Prior to last month, I'd never heard about Chitosan. It is a pretty interesting supplement. Chitosan is a fiber gotten from chitin. If you can remember your biology very well you will notice that chitin is a component in the exoskeletons of insects and crustaceans.

The Chitosan weight loss supplements are primarily gotten from safe sources; shrimps, crab and squibs. You should try it out if you don't mind some seafood.

Chitosan have been highly recommended as a supplement for reducing the absorption of fat, for the lowering cholesterol in the body, as a very detox solution for flushing toxins and for fighting diabetes.

7. Beta Glucan

This is a natural concentrated soluble fiber gotten from mushrooms, algae and yeasts. Beta-glucans could lower cholesterol, help with diabetes and weight loss.

It comes in the form of tablets, capsules and powder and has varying degrees of concentration.

Conclusion 

Clinical research for Chitosan and Beta gluten component on weight lost is limited and reviews are mixed therefore, research is inconclusive. Try out supplements from reputable brands If you are a supplement adventurer otherwise you wouldn't be getting same result as other successful users of good brands. 

Generally,  for any supplement you're about to try out, if you can, buy them in pure powder form as they are mostly without fillers or additives. This way, you'd know what you're getting.

Is there a supplement out there that you have tried and that could change someone's life? Do drop it on a comment.
