Black cumin seeds are tiny black seeds that are used to make the extract called black seed oil, a popular supplement for health. 

Also known as Nigella sativa, black caraway, and kalonji oil, black seed oil is a spice that has been used for many purposes. Lately, it has gained the attention of researchers for its ability to help reduce body weight. 

Black Seed Oil for Weight Loss

By reducing appetite, and body fat, and reducing inflammation, this powerful seed has some remarkable effects on helping people stay healthy. 

For example, one study of 875 people concluded that black seed oil significantly reduced the body mass index of participants. Another study confirmed these benefits, with black cumin seed users losing significantly more weight than those getting a placebo. They lost an average of about 4.5 lbs (2 kg), had a reduction in belly size, and also had a lower BMI after treatment. 

Yet another study found that overweight women had a reduction in BMI and LDL cholesterol while having an increase in healthy HDL levels and an increase in exercise capacity. This study used 2 grams per day of black seed oil given as capsules. 

Although the weight loss benefits of black seed oil are clear, it is best to combine it with a healthy diet and other strategies to support healthy weight, such as intermittent fasting, fermented foods like raw sauerkraut, apple cider vinegar, and regular exercise. 

Black Seed Oil for Weight Loss: Helps Reduces Blood Sugar Levels

Using black seed oil has the ability to help lower blood sugar as well. This is part of why it helps people with their weight loss efforts. 

By reducing glucose absorption and improving glucose tolerance by enhancing insulin sensitivity, black seed oil may help people who have Type 2 Diabetes. 

Black seed oil helps lower blood sugar and may do so by increasing insulin receptor production and reducing inflammation.  For example, research suggests black seed oil reduces fasting glucose levels by almost 30% compared to standard treatment which reduces fasting glucose by 18%.  

Several other studies have confirmed the beneficial effects of black seed oil on diabetes symptoms as well. 

Black Seed Oil for Weight Loss Reviews

There are thousands upon thousands of positive reviews about black seed oil’s benefits. Many people find that they have fewer aches and pains. This allows them to exercise more and have more energy.

People report losing between 12-17 pounds as a benefit of using this healthy oil as well.

I don’t review herbal supplements and am generally skeptical of the efficacy of most. I began taking ibuprofen for back pain and inflammation like candy 2-3 years ago and struggled with flexibility in my golf game due to stiffness and general inflammation for years. I stumbled on black seed oil by accident and gave it a try. It took about a month to notice, but holy crap, it worked for me and I haven’t touched an NSAID in two months. Imagine the improvement just in my digestive system. None of my doctors have even heard of it. I tried this specific product based on reviews and it’s awesome. On an empty stomach it will burn you, otherwise it’s fine. My BP also dropped, but stopping the NSAID consumption daily undoubtedly helped BP. I’m now a believer in black seed oil!

This was the first time I took the black seed oil, we shared the bottle with my daughter, she’s been having problems with PCOS, weight gain, exercises and diet weren’t working, combined with seamoss we’ve seen great results. I was experiencing inflammation in the body and weight gain after an hysterectomy, I finally lost weight and it’s been helping with my Lymphedema problem as well, we’re so happy with this.

I use this daily for my arthritis, and it makes a huge difference in the way I feel. There are also many other benefits such as weight loss, and skin conditions (helps my psoriasis). Taste? It’s in a capsule so it has no flavor.

 Magically reduced my cravings for sugary foods and helped my skin and hair!

5.0 out of 5 stars

I have read that black seed oil helps with pain, but I was not experiencing any pain when I began taking it. I started taking it to help prevent cancerous cell growth and for hair & skin health. But to my surprise, this stuff took away my cravings for sweets and it reduced my appetite. I actually lost about 6 pounds in 2 weeks. Not sure what is in it to take away the appetite, but I do not desire sugary fatty foods ever since I started taking it. When I realized this, I started doing research on black seed oil, and I found a substantial amount of research online that confirmed that it does seem to stop fat storage. If you don’t believe me, google “black seed oil and weight loss” and you will see what I am talking about.

Other positive effects I’ve noticed since I have been taking this supplement:

I also have increased energy.

My skin feels nice

My hair feels nice.

I am 51 years old. I surely do wish I would have discovered black seed oil way before now. But I’m glad I know about it now, and I will not go a day without taking it!
