What's in it?

Each capsule has GlucoVantage dihydroberberine 100 mg, R-alpha lipoic acid 100 mg, cinnamon extract 200 mg, banaba leaf extract 100 mg (1% corosolic acid), Gymnema sylvestre 75 mg and chromium picolinate 50 mcg. See every ingredient

Can I take it with my medications?

If you take medication for blood sugar or diabetes, talk to your doctor before you start, because together they could push your blood sugar too low. Berberine can change how some other medications are processed, and chromium can reduce absorption of thyroid medication (levothyroxine) if taken at the same time. Bring the label to your doctor or pharmacist.

How do I take it?

1 Daily Dose is 2 capsules: one about 15 minutes before each of your two biggest meals, with 6 to 8 oz of water. Start with 1 capsule a day before your largest meal, then add the second. One bottle lasts a month at 2 a day.

Is it a weight-loss product?

No. MetaboSync supports healthy blood sugar, steadier energy and appetite. Some customers mention dropping a few pounds, but we don't promise it.

Big meal, a glass of wine, then the crash.

A big rise in blood sugar after a meal is often followed by a dip, and that dip can feel like the slump and the snack hunt. Alcohol adds to it: with a drink before dinner, people eat more and stay hungrier through the day (1, 2).

Blood sugar and metabolism

GlucoVantage® dihydroberberine

Per serving100 mg
ResearchMeta-analysis

Why it matters: Berberine is one of the most studied plant compounds for blood sugar, but regular berberine is poorly absorbed.

What it does: A form of berberine built to absorb better. In a pilot study, 100 mg of it reached higher blood levels than 500 mg of regular berberine (3).

The research: Across placebo-controlled trials in people with metabolic syndrome, berberine lowered fasting blood sugar, triglycerides and waist size (4).

Decreased appetite, weight loss & more energy!

I've been taking MetaboSync for almost a month and have noticed decreased appetite as well as some weight loss. I also have more energy throughout the day!

Less appetite and more stable blood sugar. No crashes.

Honestly, I haven't been very consistent in using this product but I still feel like my blood sugar is more stable especially if I haven't eaten for awhile. I will keep using it.

So far, so good

I've not taken it too long, but I can tell a difference after taking it with appetite control. Helpful to me since I'm hypoglycemic and get hungry often. I think it may be helping with metabolism too. I think I've lost a few pounds, so I'm really hopeful with continued use I can lose a little more!

Questions, answered.

Still unsure? Email info@trycloud9.com and a real person will get back to you.

Will it help with the afternoon crash?

That's what it's built for. MetaboSync supports healthy blood sugar after meals, and steadier blood sugar means steadier energy. One customer put it this way: “My overall energy level has been more consistent throughout the day without the afternnon low I used to feel.”

How do I take it?

1 Daily Dose is 2 capsules: one about 15 minutes before each of your two biggest meals, with 6 to 8 oz of water. Start with 1 capsule a day before your largest meal, then add the second. One bottle lasts a month.

Can I take it with medications?

If you take medication for blood sugar or diabetes, talk to your doctor before you start, because together they could push your blood sugar too low. Berberine can change how some other medications are processed, and chromium can reduce absorption of thyroid medication (levothyroxine) if taken at the same time. Show the label to your doctor or pharmacist. Not for use if you're pregnant or nursing.

Is it a weight-loss product?

No. MetaboSync supports healthy blood sugar, steadier energy and appetite. Some customers mention dropping a few pounds, but we don't promise it.

Can I drink on days I take it?

Yes. We don't ask anyone to quit. Take it before your meals every day, drinking or not.

When will I notice a difference?

Some customers notice smaller portions and steadier energy within the first week or two. Give it at least a month of daily use to judge it.

Can I take it with Daily Restore?

Yes. Daily Restore looks after your liver and the nutrients alcohol drains; MetaboSync looks after blood sugar and appetite.

Am I locked into a subscription?

No. Subscribe & Save ships free in the US, and we email you before every renewal. Pause or cancel anytime, no fees.

What if it isn't for me?

Every order is covered by our 180-day money-back guarantee. Email info@trycloud9.com and we'll refund you, even on opened bottles.
