Selecting the right supplement for berberine is essential as berberine, a potent ingredient found in goldenseal barberry, and Oregon grapes--has amazing benefits for blood sugar control, health of the heart, gut microbiome balance, and metabolic support. There are many different berberine supplements available, and not all of them are created equally. Here are ten tips for choosing the best supplement with the highest safety and effectiveness.
1. Find a product with a high purity (=97 percent Berberine HCl or Sulfate)
The most effective berberine supplements use berberine hydrochloride (HCl) or berberine sulfate, standardized to =97% purity.
Beware of labels that are ambiguous, such as "berberine" or "berberine-free extract" without a percentage of purity.
2. Third-party testing for heavy metals and contaminants
Berberine is often taken from plants that are able to take in heavy metals (e.g., goldenseal).
Select brands that have been tested:
USP, NSF, or ConsumerLab
Independent labs (Labdoor, Eurofins)
Be sure to check for no contaminants like arsenic, microbial contamination or lead.
3. Look for formulas with enhanced absorption.
Regular berberine has poor bioavailability (~1%). Be aware of:
Berberine Phytosome (e.g. Berberine + sunflower lecithin for 3-5x more absorption).
Dihydroberberine DHB - the most stable and bioavailable form (GlucoVantage, patented version).
Liposomal berberine - Best for gut-sensitive individuals.
4. Dosage Optimal (500-1500mg daily, divided doses)
A standard dose of 500mg is taken 2-3x daily with meals.
Dihydroberberine (DHB): Lower dose needed (~100-300mg, 2x/day).
Beware of massive doses (>2000mg/day), unless under medical supervision (can disrupt gut bacteria).
5. Ingredients that are able to work together to create enhanced effects
Alpha-lipoic acids (ALA) – Boosts the insulin sensitivity.
Chromium picolinate (supports the metabolism of glucose)
Ceylon cinnamon - Enhances blood sugar control.
Silymarin, milk thistle - Protects your liver (berberine's metabolism is carried out through the liver).
6. Beware of Fillers and Allergens
Red flags
Magnesium stearate (may hinder absorption).
Titanium dioxide (potential cancer-causing chemical)
Artificial colors/flavors.
Ideal: Vegan capsules, non-GMO, gluten-free.
7. Brand Reputation and Transparency
Brands you can count on
Thorne (Berberine-500) - Pure, tested, no fillers.
Renue By Science (Liposomal Berberine) Absorption Boosted.
GlucoVantage (Dihydroberberine) - Superior bioavailability.
Avoid products with:
No batch testing report.
Fake Amazon Reviews
8. Check for Enteric Coating or Delayed Release
Berberine is a cause of stomach discomforts (nausea and cramps).
The enteric-coated capsules are absorbed by the intestines, not the stomach. This reduces side effects.
9. Think about Gut-Microbiome Suppport
Berberine is an antibiotic that kills bacteria, but it may also affect the good bacteria.
Find supplements that include:
Prebiotics (FOS, inulin) - Feed good gut bacteria.
Postbiotics Butyrate: Supports gut lining.
10. Look for Drug Interactions
Berberine interacts with
The cause of hypoglycemia is diabetes-related medications.
Antidepressants such as Cyclosporine as well as blood thinners.
See a doctor if you are on medication.
Bonus: The timing of the purchase is crucial.
Take it with food (maximizes the blood sugar benefit).
Beware of taking this medicine in conjunction in conjunction with calcium-rich foods and dairy products (can lower absorption).
Best Form Recommendation
For most people: Berberine Phytosome (500mg, 2x/day).
For better absorption: Dihydroberberine (GlucoVantage, 100-200mg, 2x/day).
For sensitive stomachs: Enteric-coated berberine HCl.

Magnesium Glycinate 10 Tips For Choosing The Right Supplement
Magnesium Glycinate is among the most bioavailable and well-tolerated types of magnesium. It's perfect for sleep, relaxation, muscle recovery, as well as anxiety reduction. All supplements, however, are created in the same way. Use these 10 tips to ensure that you're receiving the best magnesium glycinate of the highest quality.
1. Magnesium Bisglycinate Form (Not just "Glycinate")
The most stable, absorbable form of magnesium is bisglycinate.
Avoid products with just "magnesium Glycinate" on the label but not specifying Bisglycinate. These may contain lesser glycinate forms.
Look at the molecular structure True bisglycinate molecules are bound to two glycines, which increases absorption.
2. Magnesium content from Elemental Magnesium
Magnesium-glycinate is a compound, and only a fraction of it is magnesium.
Example:
1000mg magnesium glycinate ~ 140-200mg elemental magnesium.
You should look for a label that clearly states both the compound and the amount of magnesium in the elemental portion.
Optimal dose: 200-400mg magnesium elemental daily (adjust according to your needs).
3. Third-Party testing for purity & heavy metals
Magnesium can be contaminated with lead, aluminum, or arsenic.
Test brands by:
USP (United States Pharmacopeia)
NSF International
ConsumerLab
Avoid brands which do not offer Certificates of Analysis.
4. Avoid Harmful Fillers & Additives
The chemical is called titanium dioxide (potential carcinogen).
Magnesium Starate: (may result in absorption to be decreased).
Artificial colors and flavors, as well as preservatives.
Use of pure supplements
Capsules of Vegetables (hypoallergenic).
There are no bindings that are unnecessary.
5. Glycine Quality & Ratio
Glycine is calming and increases magnesium absorption.
The best ratios are 2:1 or 1:4 glycine/magnesium. (e.g. 2000mg of magnesium for each 200mg).
Avoid products containing synthetic Glycine.
6. Select trustworthy brands and transparent sourcing
Top brands
Pure Encapsulations Magnesium Glycinate (lab-tested No fillers).
Thorne Magnesium Bisglycinate
Klaire Labs Magnesium Glycinate (gentle on digestion).
Red flags
No batch testing currently available
Proprietary blends hiding doses.
Fake Amazon customer reviews
7. Check for allergies & food compatibility
Gluten-free (non-GMO), vegan (if necessary).
Beware of supplements containing:
Derivates of dairy products, shellfish, and soy.
Common allergens (unless specified).
8. Optimal dosage & timing for maximum benefits
To relax and sleep: Take 200-400mg elemental magnesium glycinate for 30-60 minutes prior to going to getting to bed.
To aid in muscle recovery: Take post-workout.
For anxiety/stress: Split doses (morning & night).
Start low (100mg), this allows you to determine your tolerance.
9. Test Bioavailability Factors
Magnesium-glycinate is more absorbent on an empty belly (but it can be taken with food if the patient is prone).
Beware of taking this product in conjunction together with iron and calcium (they compete to absorb the absorption).
Consider taking a magnesium and vitamin B6 supplement.
10. Look for ingredients that synergize (optional)
Some formulas include enhancing nutrients:
- L-Theanine (promotes relaxation).
Taurine, which aids to store magnesium in cells.
Vitamine B6 (improves the absorption).
Top Magnesium Supplements for Selections
Thorne Magnesium Bisglycinate - (pure and tested at the highest ratio).
Magnesium Glycinate Pure Encapsulations (hypoallergenic No fillers).
Klaire Labs Magnesium Glycinate Complex, (gentle but high absorption).
