About Nucific Carb-C6

Designed to specifically address “Starch Tongue,” Nucific Carb-C6 features a unique blend of six ingredients that promise to curb carbohydrate, starch, and fat cravings, thereby limiting unwanted accumulation and helping you feel better than ever.

Specifically, the website advertises this dietary supplement can help you achieve more energy throughout the day, boost your metabolism, ease hunger, slim and sculpt your physique, and support healthier blood pressure and cholesterol levels, all while continuing to enjoy your favorite foods.

According to Nucific, all you have to do is take two capsules of Carb-C6 per day before your biggest meal (or, whenever you eat the most carbohydrates and starches), and it could help you regain control of your eating habits and lead to improved mental and physical health.

This is even the case if you’ve been unsuccessful losing weight in the past, whether from the wrong diets, exercise, or pills, or a sheer lack of willpower.

Losing weight while still eating what you want? The marketing claims for Carb-C6 sound fantastic. To help you make the most informed purchase possible, though, we’ll quickly walk you through everything we learned, step-by-step.

What is Starch Tongue?

Before diving into Carb-6’s formula, let’s quickly unpack some of the claims made on the supplement’s website.

Back in 2016, a team at Oregon State University, which included food scientist Juyun Lim, found it’s possible a sixth ‘starchy’ taste element exists in the human palate—one that perhaps explains why carbohydrates are one of the main food staples in almost every culture on earth.

This is in addition to the other already established taste elements: sweet, salty, sour, bitter, and more recently added to the list, Umami (a savory sense).

However, as Jessica Hamzelou reports in New Scientist, “Before any new flavours can be enshrined as primary tastes, they must meet a strict list of criteria. Tastes need to be recognisable, have their own set of tongue receptors, and trigger some kind of useful physiological response.”

The problem, she continues, is that “Starch doesn’t tick all of these boxes yet.” Specifically, “Lim and her colleagues are yet to identify specific starch receptors on the tongue.”

TLDR; Highly preliminary clinical evidence indicates there might be another ‘starchy’ taste sense that needs to be added to our existing list (sweet, salty, sour, bitter, and Umami), although it hasn’t been formally named, and no receptors have been identified on the tongue.

Despite this, Nucific advertises their Carb-C6 supplement can “specifically address “Starch Tongue,” an overabundance of specialized carb-receptor taste buds that affect cravings for carbs and starchy foods.” Which ingredients does it use to accomplish this?

Nucific Carb-C6 Ingredients

According to the supplement facts label posted on the Nucific website, Carb-C6 contains the following:

  • White Kidney Bean Extract 300 mg
  • Mulberry Extract 200 mg
  • Hibiscus Extract 200 mg
  • Gymnema Sylvestre Extract 200 mg
  • IS-aIG Seaweed and Grape Seeds Extract 200 mg
  • Green Tea Leaf Extract 100 mg

Note: The HighYa team has collectively written about nearly 700 dietary supplements, but we’re not medical or clinical professionals. As a result, when determining if an ingredient is ‘effective’ for a specific claim, we rely on publically available summaries provided by sites like the Natural Medicines Database, Examine.com, and WebMD.

With this said, these sites indicate there’s insufficient clinical evidence that most of Carb-C6’s ingredients can deliver on the taste receptor claims advertised by Nucific. However, there are some nuances to the discussion that deserve exploring.

For example, taking 1 gram of powdered white mulberry leaf three times daily for four weeks is listed as ‘possibly effective’ for helping reduce fasting blood sugar levels in type 2 diabetics. Although, at 300 mg per dose, Carb-C6 contains much less than this amount.

Hibiscus (1.25 to 10 grams) might lower blood pressure by a small amount in people with high blood pressure, while green tea is likely effective for reducing cholesterol, and possibly effective for lowering high blood pressure, increasing bone density in those with osteoporosis, and even protect against Parkinson’s disease.

Together, these potential benefits could foreseeably help you feel better than ever, as advertised on the Carb-C6 website.

Finally, while white kidney bean extract is an extraordinarily popular weight loss supplement, ConsumerLab reports:

“Supplements containing extracts made from white kidney bean (Phaseolus vulgaris) are promoted for weight loss because they are thought to act as "starch blockers" by inhibiting the starch-digesting enzyme amylase which otherwise turns the starch you eat into absorbable sugar. However, the effectiveness of this approach is questionable. Benefits have only been shown in short-term studies.”

Are There Potential Side Effects Related to Carb-C6’s Ingredients?

On the upside, these same sites reported no side effects for Carb-C6’s ingredients. WebMD emphasizes, however, that the side effects of taking hibiscus regularly as medicine are unknown.

Regardless of any ingredient’s safety profile, it’s always a smart idea to have an in-depth discussion with your primary care physician before beginning any new dietary supplement regimen.

How Much Does Nucific Carb-C6 Cost?

Carb-C6 is only available through Nucific at the following prices:

  • 1 Bottle: $69.95
  • 3 Bottles: $184.68 ($ per bottle)
  • 6 Bottles: $344.15 ($ per bottle)

All orders come with a 90-day money back guarantee, less S&H, which you can request by calling customer support at 888-679-5520 or sending an email to support@nucific.com.

What Do We Know About the Company Behind the Carb-C6 Dietary Supplement?

Nucific is based out of Tarzana, CA and has been in business since 2015. In that time, they’ve released a line of 10 dietary supplements, including popular options like BIO X4, Deep Cell Activator, Probiotic Complex, and Dr. Amy’s Beef Bone Broth.

Speaking of which, Carb-C6 was created by Dr. Amy Lee M.D., a board-certified physician in internal medicine, clinical nutrition, and obesity medicine, who's based out of Los Angeles, CA. She’s also a Nucific board member.

As a company, Nucific held an A+ rating with the Better Business Bureau, based on 13 customer reviews and more than 40 closed complaints, as of 5/16/18. Most related to ordering problems, and a company representative provided a solution in each instance.

Are There Other Starch-Blocking Dietary Supplements Like Carb-C6?

Searching online, you’ll find dozens of amylase inhibitors (informally known as starch blockers) for sale, which work by preventing the body from digesting carbohydrates and absorbing the associated calories. Although, WebMD emphasizes the evidence is unclear as to whether or not these carb blockers can help individuals lose a meaningful amount of weight.

With this said, we didn’t encounter any third-party dietary supplements during our research that promised to block ‘starchy’ taste receptors on the tongue in the same way as Carb-C6. Nor did we encounter any with the same ingredients formulation.

Does this mean necessarily mean you should go ahead and place an order? Based on our years of research into the supplements industry, it’s our opinion that you should only do business with companies who:

  • Provide a complete list of ingredients, including dosages, with limited-to-no proprietary blends
  • Price their products competitively
  • Offer at least 30-day refund policies, with no restocking fees
  • Come with mostly positive online customer feedback

Our Final Thoughts About Nucific Carb-C6

Considering everything we’ve covered, Nucific seems to tick most of these boxes: they list all of the ingredients and dosages for Carb-C6, they stand behind the supplement with a 90-day refund policy, and they seem to come with mostly positive online customer feedback—including here at HighYa and the Better Business Bureau.

Is its $70 price tag ‘affordable’? We’ll leave it up to you to answer.

But, when it comes to dietary supplements, a big part of the overall value is related to its effectiveness. In other words, whether or not it'll deliver on its marketing claims.

Based on what’s reported by sites like New Scientist, the Natural Medicines Database, and WebMD, there’s a) only preliminary evidence indicating humans have ‘starchy’ taste receptors on their tongue (they haven’t been located), and b) there’s insufficient clinical evidence that they can be blocked by any of the ingredients found in Carb-C6.

Still, you can always request a refund within three months of purchasing if you find it doesn’t meet your needs—less S&H charges, of course.
