This is a great quality grapefruit seed extract (125 mg). It can be taken with or without meals which is very convenient. The light-beige tablets are really small in size but you can taste a little bitterness in them but it is manageable. It enhanced my immunity so that I won't get sick so easily. I used this with the higher strength capsule if I want an extra dose to it.

I tried this GSE supplement for a few weeks. The tablets are vegan, easy to swallow, and clearly labeled with 125 mg extract plus full‑spectrum bioflavonoids. NutriBiotic +2 Amazon +2 I felt a mild uptick in immune resilience and a lighter digestive feel on off‑days. Results are subtle, not dramatic. On the downside, you may need consistent use and possibly higher doses or complementary support for stronger effects. Overall: a clean, reliable option for gentle immune and digestive‑system support.

Excellent help with clearing the candida, yeast etc. I haven't used antibiotics in over ten years, I've managed to get rid of MRSA, utis, cellulitis on both legs couple times, abscesses, etcetc. with GSE and the oil of oregano.

always good
Verified purchase
I always keep a bottle on hand for many different applications from possible food poisoning to a scratchy sore throat. UPDATE: This has been a great product i keep on hand through the last few hears with all the colds and flu’s that people cant shake, if i come in contact with someone who is sick i take one immediately and it seems to save me from getting sick.
