JayLab Pro LeptiSense Overview

What you need to know about JayLab Pro LeptiSense

LeptiSense is a dietary supplement that uses natural ingredients, marketed to provide safe and effective weight loss for men and women over 30 who have at least 10 pounds to lose. The product is based on the idea that a person is not losing weight because of a hormone imbalance that leads to a lowered metabolism and increased appetite. This product can supposedly fix this, and lead to weight loss even without exercise.

It is manufactured by JayLab Pro, a supplement company founded by Jayson Hunter – a registered dietician. The company used to be called Prograde Nutrition, although this does not seem to be mentioned anywhere which seems strange.

The brand uses extremely long sales pages to tell elaborate stories, using ‘real people’ to show the efficacy of their product. The product page for LeptiSense contains a lot of jargon and bold claims. You are encouraged to sign up to an autoship program when buying the product.

What are the side effects of JayLab Pro LeptiSense?

There are some side effects associated with Guar Gum, including increased gas production and diarrhea, however these usually disappear after several days of use. High doses of guar gum or not drinking enough fluid with it can cause blockage of the oesophagus and intestines.

There seem to be incredibly high doses of Chromium Polynicotinate listed, which we presume is an error and should be 300mcg rather than 300mg. Side effects include skin irritation, headaches, dizziness, nausea, mood changes, and impaired thinking.

There are serious side effects linked to higher doses, which is very worrying based on the dose claimed on the website. These include blood disorders and liver or kidney damage.

How much does JayLab Pro LeptiSense cost?

The pricing information on the website is confusing, but it is clear that LeptiSense is expensive.

You can get a reduction if you sign up to the Subscribe and Save option. We do not advise this as autoship agreements can be very difficult to cancel, and there is no reason why you should take this supplement long term.

The price as a one off customer is $57.95 plus shipping for a bottle of 60 capsules (30 days supply). If you buy 2 bottles you get an extra one free, and if you buy 4 bottles you get two more free.

The Subscribe and Save options (auto ship) are as follows:

  • 1 pack: This option comprises of 1 bottle and costs $44.95. Shipping is free.
  • 3 Pack: This option costs $107.95. Shipping is free. This is delivered every 90 days and you are charged automatically each time. This option as well as the 6 pack still claim to have bottles free, however if that were the case then this option should cost $89.90.
  • 6 Pack: This option costs $206.95. This is delivered every 180 days and you are charged automatically. Shipping is free.

JayLab Pro LeptiSense Key Features

LeptiSense is a weight loss supplement, that claims to regulate levels of the hormone Leptin so that metabolism works as it should, regulating appetite and burning fat. The idea is good, however it is unlikely that the ingredients in the product will do much to help with this. The individual ingredients are at too low levels to have an effect, as well as there not being enough scientific evidence to support the use of them for weight loss in humans.

JayLab Pro LeptiSense Key Points

  • Manufactured by JayLab Pro
  • 60 capsules per bottle (30-day supply)
  • Comes with a 60-day guarantee

Ashwagandha could help to reduce cortisol concentrations. It has also been found to improve physical performance. However, the lowest effective dose is 300-500mg with the optimal dose being 6,000mg a day. The amount of Ashwagandha in this product is 125mg twice a day, so it wouldn’t have any effect on weight loss or metabolism.

Limited research suggests that chromium might improve weight loss in some people who are overweight or obese. But the amount of weight loss is probably not clinically significant. It is also unlikely to have any effect on metabolic syndrome. The levels stated in the ingredients is probably a mistake, but either way is worrying.

How to Take JayLab Pro LeptiSense

  • Adults take 1 capsule before a meal two times a day. Consume with 8-10ozs. of water. For best results use as part of a sensible diet and exercise program.

The marketing and sales tactics from JayLab Pro are very unusual and cagey. The sales page contains a lot of information and jargon that can be overwhelming. It is written from the founder’s perspective, and made clear that he is a Registered Dietitian who claims to have a lot of experience helping people look and feel better. He talks of ‘Elizabeth’, who had miraculous results using the ingredients in LeptiSense – however there is no evidence as to whether ‘Elizabeth’ is real or just created to sell products, nor that she actually took LeptiSense rather than individual amounts (of possibly higher doses) of the ingredients.

JayLab Pro LeptiSense Concerns

  • High levels of Chromium Polynicotinate
  • You are urged to sign up for subscribe
  • No customer reviews online

LeptiSense is also very expensive. If you do not want to subscribe to their autoship programme (which we do not advise signing up for), then you will pay $57.95 plus shipping for one months supply, for a product that is likely to do very little.

The focus on getting customers to sign up for autoship also concerns us because these so-called subscribe and save options can be difficult to cancel.

What does JayLab Pro LeptiSense claim to do?

There is so much information about the product, that it is hard to decipher exactly what it claims to do. The main thing is to bring your metabolism back under control. It claims it does this by reducing leptin resistance and helping the brain recognise your free leptin, as well as lowering cortisol levels. It suggests that Lepticore can increase weight loss without changing diet or exercising.

The product should lower cholesterol and triglycerides, lower sugar in the blood and increase fat loss and metabolism, as well as improve sleep due to lower levels of Cortisol. That is an awful lot of supposed benefits from one supplement!

The website claims that the Ashwagandha will decrease cortisol so you feel less frazzled, overwhelmed, and moody, as well as improving brain function. Chromium Polynicotinate is said to help improve “fasting glucose,” which reveals how well your body uses insulin.

Does JayLab Pro LeptiSense work?

We think the supplement is unlikely to work as described. The levels of the ingredients are too low, and there is not enough evidence to back up the claims that these ingredients will help with weight loss and metabolism. The Ashwagandha could have a positive effect on mood but wouldn’t encourage weight loss.

JayLab Pro LeptiSense Ingredients

Lepticore Proprietary Blend 300mg

Because of the numerous ingredients in this blend, we have detailed the properties of each individual ingredient below:

  • Gum Arabic: A gum exuded by some kinds of acacia. One study has linked supplementation of 30g a day with a very small amount of weight loss, but the results were not statistically significant. Source
  • Guar Gum: A fiber that normalizes the moisture content of the stool. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines. There is interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness which could decrease appetite. However, it does not seem to help people lose weight.
  • Locust Bean Gum: This tree extract is used for treating digestion problems. It may indirectly benefit weight loss by decreasing the effectiveness of some enzymes in the stomach. Source
  • Pomegranate fruit extract: Whilst eating pomegranate may improve digestion, the small amount present in diet pills is unlikely to have the same effect. Source
  • Blue green algae extract: Whilst blue green algae is nutrient dense and highly bioavailable, the clinical evidence to support its use for health reasons is currently very limited. Source
  • Beta-carotene: Beta-carotene is converted to vitamin A, an essential nutrient. It has antioxidant activity, which helps to protect cells from damage. It is recommended that it is sourced from food rather than supplements, as fruits and vegetables that contain it also offer other health benefits. Source

Other ingredients:

  • Sensoril 125mg (Ashwagandha (Withania somnifera) Root and Leaf extract (10% Withanolides)): Sensoril® is a branded formulaic extract of the Ashwagandha plant. It is thought that it lowers cortisol levels in the brain and body. Cortisol is a hormone produced during moments of stress, which has been associated with increasing weight gain, and making weight loss more difficult. Source
  • Chromium Polynicotinate 300mg: Aids in promoting a healthy metabolism.
  • Vitamin A (as beta-carotene) 5000iu
  • Also contains: Vegetable Cellulose (Capsule), Rice Flour, Magnesium Stearate.

JayLab Pro LeptiSense Side Effects

There are possible side effects from Guar Gum during the first few days of use:

  • Increased gas production
  • Diarrhea
  • High doses or not drinking enough fluid with the dose can cause blockage of the oesophagus and the intestines.

Chromium Polynicotinate can cause:

  • Skin irritation
  • Headaches
  • Dizziness
  • Nausea
  • Mood changes
  • Impaired thinking, judgment, and coordination.

There are serious side effects linked to higher doses, which is very worrying based on the dose claimed on the website. These include blood disorders and liver or kidney damage.

Caution: Not intended for use by those under the age of 18. Consult your doctor before use if you are taking any medication, or have any medical condition.

JayLab Pro LeptiSense Customer Feedback

We couldn’t find any reviews of Leptisense or JayLab Pro, and their Facebook page is also very quiet with little to no comments on posts.

JayLab Pro LeptiSense Money-Back Guarantee

The company do offer a money-back guarantee, within 60 days of delivery for a refund.

They do state that only 2 bottles can be open within the 60 day allowance, and only 1 if within 30 days.

However they do say in small print “JayLab Pro, Inc. reserves the right to make exceptions to this return policy if deemed applicable”, which seems very underhand.

Where To Buy JayLab Pro LeptiSense

You can buy it from the official JayLab Pro website.

Watchdog Verdict

JayLab Pro Leptisense does contain some ingredients that could potentially help with weight loss, however most are at a too low level.

Lepticore Proprietary Blend contains three types of gum which could expand the stomach and suppress appetite, but there is very little clinical research into how much these could impact upon weight loss, plus the levels are too low. For example, studies show low level weight loss with Gum Arabic with 10g a day and there is less than 600mg (the total blend) taken each day.

If the ingredients list on the product website is correct, then this supplement contains huge and potentially dangerous levels of Chromium Polynicotinate. Although this ingredient could aid in promoting a healthy metabolism, the amount of 300mg per capsule (or 600,000mcg per day) greatly exceeds the recommended dose of 1,000mcg a day which could lead to dangerous side effects. We presume this is an error, however we do not recommend taking this product until it is clear.

The product is very expensive and although it is covered by a guarantee, you are encouraged to sign up to autoship.

Overall, we do not recommend JayLab Pro LeptiSense to our readers.
