Blend math02

How much coleus forskohlii and the rest can 1 mL of Sugar Defender hold?

One mL of Sugar Defender holds at most about 22 mg of coleus forskohlii, from its 9th place in the 200 mg blend.

The rule is 200 divided by the place number.

Worked example

Coleus is 9th: 200 / 9 is about 22 mg. Licorice is 18th: 200 / 18 is about 11 mg. Grape seed, 2nd, tops out at 100 mg.

Coleus03

Does coleus forskohlii in Sugar Defender help with weight?

No good evidence says so. Three small trials of forskolin at 500 mg a day found no effect on body weight, and Sugar Defender holds at most about 22 mg (NIH ODS, Dietary Supplements for Weight Loss).

The sales page calls coleus a "Fat Burning Aid" (Sugar Defender sales page).

Memorial Sloan Kettering says studies proving its safety and benefit are lacking (MSKCC, Forskolin (Coleus forskohlii)).

The gap

22 mg is under 5% of the 500 mg studied, which itself did not move weight.

Claim outruns evidence

Side effects

Low blood pressure, slow heart rate and diarrhea. It may add to blood-pressure drugs and raise bleeding risk with warfarin (MSKCC, Forskolin (Coleus forskohlii)).

Drug clashes04

Which Sugar Defender herbs can clash with prescription drugs?

Grapefruit and licorice, along with coleus, are the Sugar Defender lines most tied to drug problems. Their amounts are unknown, so ask a pharmacist.

Grapefruit juice can make some statins and heart drugs build up (FDA, Grapefruit juice and drugs). Whether a seed extract does that is unknown.

Glycyrrhizin can cause irregular heartbeat with large or long-term use (NCCIH, Licorice Root).

Keep taking prescribed medicine

Never stop or change a prescribed drug because of a supplement. Show the label to your pharmacist if you take a statin, a corticosteroid or heart medicine. More: side effects.

Raspberry ketones05

Is there proof raspberry ketones in Sugar Defender do anything?

No. The only human studies of raspberry ketones used multi-ingredient products, so no benefit belongs to them alone. Sugar Defender holds at most about 15 mg (OPSS (DoD), Raspberry Ketone).

No evidence shows they are safe or effective for weight loss.

Grape seed and capsicum06

What do grape seed and capsicum add to Sugar Defender?

Grape seed and capsicum add plant compounds to Sugar Defender, but neither has solid blood sugar evidence. Grape seed may hold up to 100 mg per mL.

Grape seed may modestly affect LDL cholesterol in small studies (NCCIH, Grape Seed Extract).

Capsaicin can upset the stomach and add cough with ACE inhibitors (MSKCC, Cayenne (Capsicum)).

The panel misspells grape as "Vitis finifera". See claims vs evidence.

FAQ08

What do people ask about the other blend herbs?

People most often ask: Does coleus forskohlii burn fat? The short answer, and 5 more, open below.

Each answer starts with the direct reply, then the reason, with a source where one exists.

Does coleus forskohlii burn fat?

No trial shows it does. Three small trials of forskolin at 500 mg a day found no effect on body weight (NIH ODS, Dietary Supplements for Weight Loss). The drops hold at most about 22 mg per mL, well under even that studied amount.

Is grapefruit seed extract safe with statins?

Ask your pharmacist first. Grapefruit juice can make some statins build up in the body (FDA, Grapefruit juice and drugs), and nobody has shown whether a seed extract does the same. The drops hold at most about 18 mg of it per mL.

Do raspberry ketones work?

There is no evidence they do. Human studies only tested raspberry ketones mixed with other ingredients, so no effect can be tied to them alone, and their safety for weight loss is unproven (OPSS (DoD), Raspberry Ketone). The drops hold at most about 15 mg.

Why is licorice in Sugar Defender?

The label does not say. Monoammonium glycyrrhizinate is a salt of glycyrrhizin from licorice root, often used as a sweetener and flavor. It is 18th of 22, so 1 mL holds at most about 11 mg.

Is capsicum in Sugar Defender spicy?

No taste note is published, so we cannot say. Capsicum is chili pepper, whose heat comes from capsaicin. The drops hold at most 20 mg of extract per mL, alongside citrus extract, flavors, stevia and xylitol.

What does grape seed extract do?

Small studies suggest modest effects on LDL cholesterol, triglycerides and diastolic blood pressure, but the findings are not definitive (NCCIH, Grape Seed Extract). It is generally well tolerated. In the drops it is 2nd of 22, at most 100 mg per mL.
