Is Berberine B1G2 worth it?
Worth a look (5.4/10). Berberine B1G2 states its dose plainly on the bottle, 1200mg of berberine per serving, which lands close to (if a bit under) the 1500mg daily doses used in the small clinical trials that found berberine lowered blood sugar about as well as metformin. That is more transparent than most ClickBank supplements we have reviewed. The problem is the guarantee: the sales page advertises '180 days, no questions asked' in multiple places, but the ClickBank order form we actually reached lists a 60-day return window, a meaningful gap between marketing and contract. Treat any blood sugar or cholesterol benefit as supportive at most, not a replacement for prescribed medication, and confirm the guarantee terms again before paying since only what the order form says is enforceable.
What we liked
- Single active ingredient with a stated milligram dose (1200mg berberine per serving), unusually transparent for this market
- Dose is within a reasonable range of the amounts used in published berberine trials
- One-time purchase with a 2-free or 4-free bundle, no subscription found
- Named founder and a listed phone number and support email
What we didn't
- Sales page advertises a 180-day guarantee that the ClickBank order form does not match (60 days)
- Weight loss and appetite claims are marketed more confidently than the underlying berberine evidence supports
- No visible third-party testing certificate despite a testing badge existing in the page code
- Dose is somewhat below the 1500mg/day used in the key cited-type trial
- Shipping is not free on the base $49 offer
What is Berberine B1G2?
Berberine B1G2 is a capsule supplement from Science Natural Supplements, a ClickBank seller whose founder is named on the page as Cody Bramlett. It promises support for healthy blood sugar already in the normal range, easier weight loss, appetite control, and support for cholesterol, energy and stress. The bottle label visible in the product photo states '1200mg Per Serving' and '60 Capsules', with a note about supporting cholesterol levels and weight loss.
The offer is framed as 'Buy 1 Get 2 Free' for $49, discounted from a listed $196 regular price, with an upsell to 'Buy 2 Get 4 Free' for $98 that adds free shipping. The page has no subscription language and describes it as a one-time purchase.
It is sold through ClickBank. Charges appear on the buyer's statement as Science Natural Supplements, and the company also lists a phone number and support email directly on the page, more contact detail than many ClickBank sellers provide.
Format: Capsule, 60 per bottle, label states 1200mg berberine per serving. Sold by: Science Natural Supplements (sold through ClickBank).
What is on the Berberine B1G2 label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
The label is refreshingly simple: one active ingredient at a stated milligram amount, rather than a blend that hides individual doses. We could not verify the berberine form (such as berberine HCl) or confirm third-party lab testing beyond the marketing badges shown on the page.
Do the Berberine B1G2 claims hold up?
"Support healthy blood sugar levels already within normal range"
This is FDA-safe structure/function wording rather than a treatment claim, and it is consistent with published research: a controlled trial (Yin et al., 2008) found 1500mg/day of berberine lowered fasting glucose and HbA1c about as effectively as metformin in people with type 2 diabetes. At 1200mg/day, this product's dose is somewhat below that studied amount.
"Achieve easier weight loss" and "lose weight faster and easier"
Berberine's effect on weight is more modest and mixed in the research than its blood sugar effect; most trials measure metabolic markers rather than significant fat loss. Weight loss claims here are considerably more confident than the underlying evidence.
100% Money Back Guarantee: 180 days, no questions asked
This claim appears at least four times on the sales page and in the FAQ, but the ClickBank order form we reached for this product states a 60-day refund window, not 180 days. The two do not match.
"We cut out the middleman... so we don't spend money on billboards or celebrity endorsements"
This is a marketing explanation for the price and cannot be independently verified one way or the other.
How much does Berberine B1G2 really cost?
| Option | Total | Per month | Shipping |
|---|---|---|---|
| Buy 1 bottle, get 2 free (3 bottles total) | $49 | $16.33 | Shipping added unless you pick the paid free-shipping upgrade |
| Buy 2 bottles, get 4 free (6 bottles total) with free shipping | $98 | $16.33 | Free shipping (upgrade offered at checkout) |
The base offer is one bottle of 60 capsules (a 30-day supply at 1200mg/day if that is one serving per day) with two free bonus bottles, for $49 total plus shipping and handling; our test checkout totaled $58.95 with shipping added. That works out to roughly $16 to $20 a month across the 3-bottle set, cheap for a supplement if you use all three bottles.
A checkout upsell offers 2 bottles plus 4 free (6 bottles total) for $98 with free shipping, extending the same per-bottle price across twice the supply and avoiding the shipping charge.
Because this is a one-time purchase with no subscription found on the order form, the total cost is capped at what you pay upfront, unlike a recurring shipment model.
The standard $49 order adds shipping and handling at checkout (the order form total came to $58.95 with shipping in our test). A $98 upgrade for 2 bottles plus 4 free adds free shipping. Exact shipping cost depends on the address entered.
Can you get a refund on Berberine B1G2?
60-day window. The sales page repeats a '180 days, no questions asked' guarantee throughout, including a dedicated guarantee section and FAQ answer. The actual ClickBank order form we reached, however, sets the return window at 60 days. Since ClickBank processes the payment and any refund, we use the order form's 60 days as the real, enforceable window and flag the mismatch with the marketing.
Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.
Which red flags did we find?
- Guarantee mismatchThe sales page advertises a 180-day guarantee repeatedly, but the actual ClickBank checkout sets a 60-day return window.
- Dose slightly under studied amount1200mg/day berberine is below the 1500mg/day used in the diabetes trial most often cited for this ingredient, though still in a reasonable range.
- Weight loss claims outrun the evidenceBlood sugar evidence is the strongest part of berberine's research; the page markets weight loss just as heavily, with weaker support.
- No verified third-party testingA '3rd Party Tested' badge exists in the page's code but is commented out and not displayed, and no certificate of analysis is linked.
- Scarcity pressureThe page says it is 'considering limiting quantities to 6 Bottles because of the incredible demand', a common urgency tactic that is unverifiable.
Who should buy Berberine B1G2, and who should skip it?
It may suit you if
- You want a single-ingredient berberine supplement with the dose stated plainly on the label, and you understand it may support blood sugar and cholesterol modestly rather than replace medication.
- You are comfortable with a 60-day refund window (not the advertised 180 days) and plan to test the product within that time if you want the option to return it.
Skip it if
- You are relying on the specific 180-day guarantee advertised on the sales page; the order form we reached only supports 60 days.
- You take metformin, other diabetes medication or blood pressure medication; berberine can interact with these and needs a doctor's input first.
- You are pregnant or breastfeeding; the page itself says there is limited safety research for this group.

Berberine B1G2 FAQ
Is Berberine B1G2 legit or a scam?
It is a real supplement sold through ClickBank with a named company, phone number and refund option, so it is not a scam in the sense of taking payment for nothing. The main concern is that the advertised 180-day guarantee does not match the 60-day window on the actual order form.
How much does Berberine B1G2 cost?
The base offer is $49 plus shipping for 3 bottles (buy 1, get 2 free), which totaled $58.95 with shipping in our test. A $98 offer for 6 bottles includes free shipping. We found no subscription.
What is the refund policy?
The sales page claims 180 days, but the ClickBank order form we reached states a 60-day return window, which is the enforceable contract since ClickBank processes refunds. Confirm the terms again at your own checkout before assuming 180 days applies.
Berberine B1G2 side effects?
The page notes possible mild digestive discomfort, consistent with general berberine research, and advises checking with a doctor if you take blood sugar or blood pressure medication because of interaction risk.
Does berberine really work for blood sugar?
A small clinical trial found 1500mg/day of berberine lowered blood sugar and HbA1c about as well as metformin in people with type 2 diabetes. This product's 1200mg/day dose is somewhat below that studied amount but in a plausible range; it is not a substitute for prescribed diabetes treatment.
