SafSlim Review


SafSlim and its high-linoleic safflower oil is all the hype in the weight loss world now. Montel Williams appeared on the Dr. Oz show to talk about this product, and it became famous instantly. SafSlim’s only active ingredient is safflower oil which is claimed to reduce belly fat and curb appetite.

I’ve never heard of safflower oil as an effective weight loss ingredient, so I was suspicious. I decided to dig deeper and see if there’s any truth behind the hype of SafSlim.

What Is SafSlim?

SafSlim is a weight loss drink manufactured by Re-Body Inc. It’s just high-linoleic safflower oil with flavor added to it. It comes in 16 or 32 ounce bottles of cream or more convenient packets. You take one tablespoon of this creamy oil mix twice a day, 30 minutes before meals.

It is backed by famous TV celebrities Montel Williams and Dr. Oz. The claim is that SafSlim reduces belly fat, curbs appetite and reduces cravings.

Who Is SafSlim For?

SafSlim is targeted at people with belly fat to lose. The claim is it works for all people with extra weight around their midsection. The only clinical study listed on the official site targeted post-menopausal obese women. Ohio State University completed a study on 35 women who fit these qualifications.

For 36 weeks, participants were given either conjugated linoleic acid (CLA) or safflower oil supplements. The CLA group saw a reduction in body mass index. The safflower oil group saw lowered fasting glucose.

No testing has been done on younger women or men.

What’s Inside?

SafSlim is a patent-pending formula made predominantly of high-linoleic safflower oil. The proprietary blend is called SAFactive78. It contains 78% safflower oil and is sweetened with xylitol.

Aside from one limited study mentioned on the official website, there are few successful studies linking safflower oil to weight loss.

The Journal of Nutrition published a study on the effect safflower oil has on weight loss. One group of test rats was fed 14% safflower oil plus 2% corn oil for 4 weeks. Then they were fed 50% of that same diet for 4 more weeks. At the end of the study, the fatty acids (safflower oil) had no effect on body weight or fat. [1]

What Users Think

Not all supplements work for everyone, and SafSlim is no exception. Reviews for SafSlim are very diverse. It has a 3.4 out of 5 star rating on, and its reviews are split evenly.

Some users say it tastes like a smoothie and others say they have to gag down their servings. Some people see a significant change in belly fat, and others use it for months and actually gain weight.

Overall, positive reviews tend to praise SafSlim more for its ability to reduce cravings and curb appetites than its ability to burn belly fat. Amazon user Steva Gils says, “After my first week of taking SafSlim, it has totally cut my desire to overeat. I do not crave sweets like I was before.”

Other users say the recommended change in caloric count and increase in exercise are what actually makes the difference. Amazon user Donald Holloway says, “I saw no difference whatsoever. Save your money and just diet and exercise.”

Amazon user Ange sums it up when she says, “It is not a cure all for weight loss, and like anything else, you have to give it time.”

SafSlim Positives

There are some advantages users see with SafSlim.

• Natural ingredients
• Reduces cravings
• Boosted energy
• Good taste
• Little to no side effects
• Official site admits it works best in combination with healthy diet and exercise

SafSlim Negatives

There are several disadvantages to SafSlim, and most surround the fact that it has not been tested enough.

• Expensive
• Not enough research
• Whole concept based on one study
• Bottle doesn’t last a whole month as claimed
• No listed return policy or trial offers

Are There Side Effects?

Side effects with SafSlim are uncommon, though some people do experience mild issues. Some SafSlim users complain about stomach cramps or diarrhea. According to WebMD, people with allergies to ragweed should be especially careful when taking supplements that contain safflower oil, as it may cause a reaction.

Is SafSlim Affordable?

Bottled cream supplement:
Official site: $56.99/32 oz, $29.99/16 oz $18.76/16 oz

Official site: $34.99 $29.44

Is SafSlim a Good Option?

SafSlim is supposed to be combined with healthy diet and regular exercise. The label says “Use in conjunction with a reduced-calorie diet and exercise program.” Critics argue it’s the reduced calories and increased exercise that make the actual difference – not SafSlim itself. And I agree.

While I’m sure some people have seen success with SafSlim, it seems that the majority of results come from the change in lifestyle that accompanies SafSlim. The entire concept is based on one limited study, which isn’t enough to win me over.
