Ultra Primal Lean

Updated May 16, 2019.
Published Dec 6, 2015.

The Paleo diet is growing in popularity, and supplements like Ultra Primal Lean have sprung up to complement it. That’s the thing to remember with products like this one, it does not replace the Paleo diet, it is to be used alongside it. Ultra Primal Lean may help you feel fuller and affect your blood sugar levels, but it’s probably not going to do much more than that. It is a relatively safe supplement though, and you are covered by a money-back guarantee if you don’t like it or if it doesn’t work for you.


  • Clear ingredients profile.
  • Looks safe. Should not cause side effects
  • Comes with a money-back guarantee if you by direct from the product website.


  • Misleading advertising. It won’t enable you to eat what you want and still lose weight.
  • Very indifferent customer feedback.
  • Unlikely to have much effect.
Ultra Primal Lean Primal Force
Ultra Primal Lean is a supplement described as the most advanced Paleo weight loss tablet ever created. The Paleo diet is popular right now with many people trying to stick to the food of our ancestors, so can you forget about that and just take a pill for the same effects?

We take an in-depth look at Ultra Primal Lean to find out.

Ultra Primal Lean Overview

What you need to know about Ultra Primal Lean

Despite all the advertising that claims that this supplement will allow you to eat again and is similar to taking the Paleo diet, without actually keeping to the diet, this supplement does not look very good.

The few customer reviews are not very positive about it and take away the hype about Paleo and it looks to be a very standard looking supplement.

If you were to use it with a weight loss plan (of any type), you may notice some benefits but results are unlikely to be earth-shattering.

Taking ingredients that are described as carb blockers such as white kidney bean extract and garcinia cambogia can encourage you to overeat in the belief that it will not add to weight.

We like that this supplement looks safe but that is the best we can say about it.

What are the side effects of Ultra Primal Lean?

Side effects may include diarrhoea, flatulence, nausea, gas, weight gain, and changes to blood sugar levels.

How much does Ultra Primal Lean cost?

Two bottles (a 2-month supply) costs $55.95 from the official website.

Ultra Primal Lean Key Features

The Paleo diet is popular right now. The idea is that you stick to the foods of the Palaeolithic age in order to benefit from a more natural diet and live the way that our bodies intended. According to its many supporters, this means high protein and low carbs.

It is interesting to note that the Palaeolithic age lasted from 2.6 million years ago to about 12,000 years ago, so whatever we were eating back then, it was certainly for longer than our modern diet of the last 50 years or so. The idea is that modern foods are the reason for obesity because our bodies are not designed to deal with fast food and food additives and chemicals.

Some fans take this further and avoid milk and dairy too, as well as legumes and some vegetables. In truth, there is a lack of evidence about what the people of this period ate, but that is nit picking. It certainly wasn’t burger and fries washed down by a milkshake or soda!

Ultra Primal Lean Key Points

  • Ultra Primal Lean is devised by Dr Al Sears a Florida based doctor.
  • Each bottle contains 60 capsules – one month’s supply.
  • Comes with a no strings attached guarantee.

Ultra Primal Lean is a weight loss supplement that claims to reset your metabolism that modern eating habits and an unhealthy diet have disrupted. By doing this you can prevent against food cravings and bad eating habits and get healthier and thinner into the bargain.

How to Take Ultra Primal Lean

Take 1 capsule 30 minutes before breakfast and 1 capsule 30 minutes before lunch.

Ultra Primal Lean contains some reasonable ingredients. The two principle components are white kidney bean extract and garcinia cambogia. Two ingredients that may help you feel fuller as well as prevent dietary carbs and sugars from adding to fat.

The supplement also contains seaweed extract Fucoxanthin which probably was a common dietary foodstuff for some Paleo people. Seaweed contains iodine an important mineral essential for health. Many people lack iodine in diet because it is mainly contained in seafood and fish although it is present in eggs.

The final ingredient is chromium – a trace mineral that appears to help the body manage insulin.

Ultra Primal Lean Concerns:

  • Will the guarantee be honoured? We have been unable to find any customers who have reported they received their money back.
  • Claims to “reset” the metabolism but people who have taken this supplement report otherwise.
  • Is this supplement just jumping on the Paleo diet bandwagon? We have seen all these ingredients in other non-Paleo supplements.

Ultra Primal Lean is part of a supplement range called Primal Force, which is designed by Dr Al Sears, who has been heralded as America’s No 1 Paleo Physician. Based in Florida, he specialises in anti aging and has been recommending the low carb high protein diet to his patients for the last 20 years.

His supplement range includes Primal Force Ultra Accel, Focus IQ, a nootropic supplement, and Estro Cleanse to remove unwanted oestrogen from your body.

According to Dr Sears, Ultra Primal Lean and all the other supplements in the range come with a 100% unconditional money-back guarantee.

What does Ultra Primal Lean claim to do?

Paleo Made Easy. Finally… You Can Eat Again

According to the product information, Ultra Primal Lean works in five ways to help you get thin and stay thin:

  • Blocks carbs from being stored as fats,
  • Reignites your metabolism so you burn more fat
  • Resets your body’s “fat signals” so you make and store less fat,
  • Calms your appetite so you don’t feel as hungry during the day.
  • Reduces your cravings so you cheat less between meals

The product information is provided by Dr Sears and he explains the Paleo diet.

Paleo is effective because it brings us back to the foods you and I were designed to eat — the foods our Palaeolithic ancestors thrived on for millions of years.

But in today’s world, there’s a problem: Your metabolism is wrecked.

Everything you eat and drink makes you hungrier.

The food manufacturers design it that way.

Eat a “modern” diet and the constant hunger sets off an alarm. In response, your body stores everything as fat to hedge against starvation.

According to Dr Sears you can reset and boost your metabolism to get “the lean, toned body you want” by taking this supplement.

There are no links to clinical evidence but because Dr Sears is a doctor, his claims seem more convincing than they would otherwise.

Does Ultra Primal Lean work?

Ultra Primal Lean looks to be safe but you probably will not notice any effect overnight. It may reduce your appetite by making you feel a little fuller and this in turn may lead to weight loss if you listen to your body and take the supplement over time.

However, the problem is that we don’t only eat just when we are hungry or drink when we are thirsty. We eat and drink for lots of different reasons that are nothing to do with appetite and this supplement will not protect you from social issues or build up your willpower.

In addition, this supplement is not going to replace any sort of weight loss diet or healthy eating plan. That said it may help support your diet. If you are taking steps to lose weight, you may find that this supplement keeps you on the straight and narrow and help you avoid overeating and snacking.

Ultra Primal Lean Ingredients

Ultra Primal Lean is a general purpose weight loss supplement that comes with the claims it will “reset” your metabolism.

Each capsule is equal to one serving.

  • Chromium (200mcg): Chromium is a trace mineral, which means the body requires very little, but it is present here in safe amounts. Research suggests it may help regulate blood sugar and it is being tested for a treatment of diabetes. It may have many benefits to health and weight loss but it requires more clinical research to fully assess its potential.
  • Irvingia Gabonensis (150mg): Also known as African mango seeds, this high fibre ingredient may have weight loss benefits. It is believed to promote leptin- the hormone that signals feelings of satiety and it has undergone human clinical testing that displayed very positive results. In one clinical test carried out in Cameroon, it was found that taking 150mg of the extract twice a day led to significant improvements to body weight, body fat, waist circumference and LDL cholesterol
  • Fucoxanthin (300mg): Also known as brown seaweed, Fucoxanthin is often eaten in Japan and appears to have benefits for weight loss. It seems to target a protein called UCP1 that increases the rate at which abdominal fat is burned although scientists cannot understand fully why this happens. Abdominal fat, also called white adipose tissue, is the kind of fat that surrounds our organs and is linked to heart disease and diabetes. Seaweed contains iodine.
  • Garcinia Cambogia (500mg): According to the product information, Garcinia Cambogia is a powerful appetite suppressor that helps you control cravings and feel fuller faster so you eat less and cheat less. However, the scientific evidence is not conclusive. Although this ingredient has performed well in animal testing, the effects upon humans seem small. The Journal of Obesity concluded that Garcinia could cause short-term weight loss but the effect was so small the clinical relevance is uncertain. They advised, “Future trials should be more rigorous and better reported.”
  • White kidney bean extract (500mg): Marketed as a natural carb blocker, white kidney bean contains a chemical called amaylse, which prevents digestive enzymes from absorbing starch. Instead, foods containing starch pass through the body as waste so do not add to weight gain. This safe ingredient is the principle component of OTC supplements such as XLS Medical.

Ultra Primal Lean Side Effects

Ultra Primal Lean may cause side effects that may include:

  • Stomach discomfort
  • Diarrhoea
  • Nausea
  • Flatulence
  • Gas
  • Changes to blood sugar levels
  • Weight gain

Not suitable for individuals under 18. Avoid if you are pregnant or breast feeding. Speak to your doctor first if you are taking diabetes medication – this supplement may change blood sugar levels. Avoid if you have any health issues around thyroid – fucoxanthin contains varying levels of iodine so this supplement will not be suitable.

Ultra Primal Lean Customer Feedback

There is some customer feedback for Ultra Primal Lean. The good news is that people have not reported unpleasant side effects.

The bad news is that some people have put weight on or not noticed any effects at all.

One customer said:

Been taking Ultra Primal Lean for 6 weeks. Haven’t seen any changes at all. In fact, I feel like I’ve actually gained weight. I eat very well, exercise 4 times per week and was hoping to lose 20-25 pounds. Unfortunately this didn’t work at all.

One customer used the supplement in the hope it would reduce glucose levels but was disappointed:

After taking two bottles – 2 or 3 pills a day with careful following of my glucose level via two to four measurements a day and weight tracking and keeping a detailed log has shown no improvement for me.

Other customer comments include:

Lost only one pound, and no girth.


Not sure it worked as advertised

Watchdog Verdict

Ultra Primal Lean looks to be a reasonable looking supplement. It is unlikely to cause side effects and it may help you feel fuller and have an effect upon blood sugar levels too.

However, it is not the Paleo diet in a bottle and if you are expecting miracles from this supplement, you are going to be disappointed as are many of the customers on Amazon.

The problem is that although it may help support a weight loss diet and help you manage hunger pangs you probably would have to commit to taking it long term for any benefits and in our opinion, it is just not worth it.

Making lifestyle and dietary changes that you could live with, such as eating more fibre and fish would probably be a better option. And after all the money you spent on this supplement would go a long way in the grocery store.

We like the guarantee. It looks good. We just wish we could have found someone who had actually claimed it so we could say for sure that this supplement is as risk free as it looks. This is no reflection upon Dr Sears himself but in the diet pill industry; there are many promises made which are never kept.

Overall, we don’t think this supplement looks good enough to add to our approved list so although it has some good points we have no other option but to reject it.
