According to the instructions on the label, the dose is 2 capsules, twice daily with a meal. There were no further details on the site, nor on the product label about dosage.

The manufacturer lists no side effects but does recommend consulting your healthcare professional prior to use if you have or suspect a medical condition, are taking prescription drugs, or are pregnant, or are lactating. The product reviews contained many criticisms with regards to safety and side effects that were not mentioned on the label or on the website. Reviewers state that they have experienced side effects such as palpitations, headaches, and stomach aches.  Many reviewers were disappointed in the lack of information about side effects.


It is not possible to purchase directly from Natrol’s main website, but there is a link to “Retailers” where you can purchase from online stores including; iHerb, Amazon, the Vitamin Shoppe, Walmart, and many others. Compared to some of the leading competitors in the diet supplement market, Natrol’s Carb Intercept 3 is quite reasonably priced and costs about $13 per bottle of sixty pills plus shipping which varies by store and amount of purchase.


From their website or elsewhere, there are no indications that Natrol offers any kind of guarantee or return policy. Reviewers complained of the lack of guarantee. We share their disappointment and feel that a company confident in its product should offer a strong guarantee, allowing the customer to try the product without risk.

Conclusion – Natrol Carb Intercept 3

There are some things to like about Carb Intercept 3. It has a simple ingredient list and is suitable for vegetarians and vegans. The price of Carb Intercept 3 seems somewhat lower compared to similar products. There are many positive reviews for this product online which suggests that many people have had positive experiences in losing weight when using Carb Intercept 3. Furthermore, there is a good chance that the main ingredients of Phase 2 Carb Controller Complex, caffeine, and green tea are all beneficial to your overall weight loss program.

Unfortunately, we do have concerns. Some users have experienced side effects that include; stomach discomfort, heart palpitations, and headaches, and many complained of the lack of information about possible side effects on the label or website. Lastly, there is no product guarantee or return policy, which causes us to question the efficacy of the product. After careful review, we therefore feel that we cannot recommend this product.
