Premier Research Labs Greens is a fermented greens powder from PRL. Learn what's inside, how it's made, how to use it, and what to check before buying.
Premier Research Labs Greens is a fermented greens powder made by Premier Research Labs (PRL), a supplement company founded by Dr. Bob Marshall. It combines organic plant powders with a probiotic fermentation process and is sold as a daily drink mix. It is a dietary supplement, not a treatment or cure for any health condition.
What Is Premier Research Labs Greens?
Premier Research Labs Greens is part of the brand's Premier line of whole-food-based supplements. The product is designed to add a concentrated source of plant powders to your day, usually mixed with water or juice.
Typical greens blends from PRL include ingredients such as organic kale, spinach, broccoli, parsley, and sea vegetables like chlorella or kelp. The formula is fermented with probiotics, a step the company says supports digestibility and nutrient availability.
Greens is sold as a powder, not a capsule or tablet. That makes it easy to adjust serving size, but it also means you need to check the label for the exact scoop size and directions. The product is sometimes listed as premier research labs fermented greens because of the fermentation step.
Fermented Greens vs. Regular Greens Powders
Fermentation is the main difference between PRL Greens and many conventional greens powders. During fermentation, beneficial bacteria partially break down plant compounds, which may change texture, taste, and how the powder mixes.
The table below compares general features of fermented greens powders and standard, non-fermented greens powders. Specific results vary by brand and by person.
| Feature | Fermented Greens Powder | Standard Greens Powder |
|---|---|---|
| Production | Plant powders fermented with probiotic cultures | Dried and milled plant powders, no fermentation step |
| Probiotic content | Often includes live or inactivated probiotic strains | Usually none unless added separately |
| Digestibility claims | Marketed as gentler on the stomach | Not typically marketed for digestibility |
| Taste | Often described as earthy or slightly tart | Varies widely; can be grassy or sweetened |
| Typical use | One scoop daily in water or juice | One scoop or capsule daily |
Neither type is a substitute for eating whole vegetables. A greens powder can fill gaps in a busy day, but it does not replace a balanced diet.
How People Typically Use PRL Greens
Most users mix one scoop of Premier Research Labs Greens with 8 to 12 ounces of water, juice, or a smoothie. The label directions are the best guide, because scoop sizes differ between products and versions.
Common timing includes:
- Morning, before or with breakfast.
- Mid-afternoon, as a lighter alternative to coffee.
- Post-workout, mixed into a protein or recovery shake.
Start with a smaller serving if you are new to greens powders. Some people notice bloating or loose stools in the first few days, especially if they are not used to fermented foods. If that happens, pause and talk to a healthcare professional.
What to Check Before Buying
Quality varies in the greens powder market, so a few checks can help you decide whether this product is right for you.
- Third-party testing: Look for a certificate of analysis or a statement about heavy metal and microbial testing.
- Manufacturing standards: A cGMP, or current Good Manufacturing Practice, facility is a baseline sign of quality control.
- Allergen and iodine content: Sea vegetables like kelp can be high in iodine, which matters for people with thyroid conditions.
- Fillers and sweeteners: Some greens powders add sugar, artificial flavors, or maltodextrin. Check the other ingredients list.
- Return policy: Buying from a retailer with a clear refund window reduces risk if the taste does not work for you.
Premier Research Labs Greens is a dietary supplement, and supplements in the United States are not reviewed by the FDA for effectiveness before they are sold. That makes label reading and a conversation with your doctor especially important.
How PRL Greens Fits With Other Premier Research Labs Products
PRL sells a wide catalog, so many buyers order Greens alongside other items. A few common pairings include:
- Antioxidant support: Some shoppers add premier research labs vitamin c to their daily routine.
- Workout recovery: Athletes may combine Greens with premier research labs creatine or a protein powder.
- Topical care: Items like premier research labs castor oil serve a completely different purpose and are not taken as a greens replacement.
- Broad daily formulas: Customers who want a wider nutrient blend sometimes try premier research labs gold-360 instead of or in addition to Greens.
The company's backstory matters to some buyers. If you want to know who is behind the brand, searching for dr bob marshall premier research labs will lead you to the founder's writings and interviews.
Premier Research Labs Greens is not a cure for any disease, and it should not replace prescribed medication or a doctor's care.
Safety and Side Effects
Greens powders are generally well tolerated, but they are not risk-free for everyone. Possible issues include:
- Gas, bloating, or changes in bowel habits when you first start.
- Allergic reactions to ingredients such as parsley, kelp, or chlorella.
- Excess iodine from sea vegetables, which can affect thyroid function in sensitive people.
- Interactions with blood thinners or other medications, depending on the plant ingredients.
Talk to your healthcare provider before using Premier Research Labs Greens if you are pregnant, nursing, taking prescription medication, or managing a thyroid condition. Stop using it and seek medical advice if you notice hives, swelling, or severe stomach pain.
Bottom Line
Premier Research Labs Greens is a fermented greens powder sold as a daily supplement, not a medicine. It may help some people add more plant-based nutrients to a busy routine, but it does not replace vegetables, and individual results vary.
Check the label, look for testing and cGMP claims, and ask your doctor if you are unsure. If you decide to try it, start with a small serving and give your body time to adjust.
