Description
1st Phorm Probiotic
8 billion CFUs across 10 strains, in a shelf-stable vegan capsule with a prebiotic included. One capsule, once or twice daily.
Your note captures the two things that matter about it: it is shelf stable, and the effect shows up over weeks rather than days.
Why shelf stable is the specification to care about
This is the thing most people buying a probiotic do not know, and it determines whether the product works at all.
CFU stands for colony forming units — living bacteria. A probiotic only does anything if those bacteria are alive when you swallow them. Dead bacteria are inert.
Bacteria are fragile. Heat, moisture and time all kill them. Which means the number printed on a bottle is not necessarily the number reaching you: a product manufactured at 20 billion CFU can arrive at a fraction of that after weeks in a warehouse, a delivery truck in summer, and a shelf.
Shelf stable means the strains and the manufacturing are chosen so viable counts survive without refrigeration. That is a genuine formulation decision, not a marketing word, and it is why some probiotics live in a fridge and others do not.
The practical version: a shelf-stable 8 billion CFU product you can keep in a cupboard and take consistently beats a fragile 50 billion CFU product that has been sitting in a warm van.
Ten strains, and why variety matters more than the number
The blend covers Lactobacillus acidophilus, casei, salivarius, plantarum, rhamnosus and brevis, plus Bifidobacterium bifidum, lactis and longum, and Streptococcus thermophilus.
That spread matters because probiotic effects are strain-specific, not species-general. Different strains colonise different parts of the digestive tract and do different things. L. acidophilus is the most researched and one of the most common naturally occurring strains in the human gut. Bifidobacterium species concentrate further down, in the large intestine.
A single-strain product at a huge CFU count covers one job thoroughly. A multi-strain product covers more ground. For general digestive support rather than a specific clinical target, breadth is usually the more sensible choice.
Honest framing on CFU counts
You will see probiotics advertising 50 or 100 billion CFU and assume more is better. It is not that simple.
Research generally places effective doses somewhere between 1 and 100 billion CFU — a very wide range, because the right number depends on the strain and the outcome being studied. Beyond a point, additional CFUs are not doing more; your gut has finite colonisation sites.
8 billion sits comfortably inside the researched range. It is not the biggest number on the shelf and it does not need to be. Viability, strain selection and daily consistency matter more than the headline figure.
The prebiotic is a smart inclusion
The formula includes fructooligosaccharides (FOS), a prebiotic fibre.
Probiotics add bacteria. Prebiotics feed the bacteria already living there. Including both means you are not only introducing new strains but supporting the population that is already established — which is the more durable half of the equation.
One caution: FOS is a FODMAP. If you follow a low-FODMAP diet or have IBS, fructooligosaccharides are a common trigger and this is worth knowing before you buy.

How to take it
- One capsule with a meal, once or twice daily. Food buffers stomach acid, which improves the odds of bacteria surviving the journey.
- Plenty of water — 12 to 16 ounces. This is on 1st Phorm's own guidance and it is worth following.
- Give it weeks, not days. Your note is right about this. Changes in the gut environment build gradually, and most people who report a difference notice it somewhere in the two-to-four week range.
- Consistency over dose. One capsule every day beats two capsules sporadically.
- Store somewhere cool and dry. Shelf stable does not mean indestructible, and a hot car will still reduce viable counts.
- If you are prescribed antibiotics, take the probiotic several hours apart from the dose rather than alongside it.
Who this is for
- Anyone dealing with ongoing bloating or irregularity who wants to try the simplest intervention first
- People who have recently taken antibiotics
- Anyone eating a lot of protein and training hard, which puts real load on digestion
- People who want a probiotic they can keep in a gym bag or a desk rather than a fridge
- Anyone travelling, where diet and routine both change
Who this is not for
Check your overlap. If you already take Opti-Greens 50 at 5 billion CFU, Jocko Greens at 9 billion, or Micro Factor at 8 billion, you may already be covered. Adding a separate probiotic on top of any of those is often unnecessary — ask us and we will help you work out what you actually need rather than selling you a duplicate.
If you follow a low-FODMAP diet or have IBS, note the FOS.
If you are immunocompromised or have a serious medical condition, speak to your doctor before taking live bacteria.
If you have a diagnosed digestive condition, that is a doctor conversation. A probiotic is support, not treatment, and we are not going to pretend otherwise.
Expect a settling-in period. Some people get mild gas or bloating in the first week. It usually resolves.
Stack it with: fibre, which feeds the bacteria. Revive Daily Greens carries a substantial fibre load if that is a gap for you.
Frequently asked questions
What does shelf stable mean and why does it matter?
CFUs are living bacteria, and they only work if they are alive when you take them. Heat, moisture and time kill them. Shelf stable means the strains and manufacturing are chosen so viable counts survive without refrigeration — so the number on the bottle is closer to the number reaching you.
Is 8 billion CFU enough?
Yes. Research places effective doses somewhere between 1 and 100 billion depending on strain and outcome. Beyond a point more CFUs do not do more, since your gut has finite colonisation sites. Viability and consistency matter more than the headline number.
How long before I notice anything?
Weeks rather than days. Most people who report a change notice it in the two-to-four week range with consistent daily use.
Should I take it with food?
Yes. Food buffers stomach acid, which improves the number of bacteria surviving to the intestine. Drink 12 to 16 ounces of water with it.
What is FOS?
Fructooligosaccharides, a prebiotic fibre that feeds the bacteria already in your gut. Probiotics add bacteria; prebiotics feed the ones you have. Note that FOS is a FODMAP.
Does it need refrigerating?
No, that is the point. Keep it somewhere cool and dry, and out of a hot car.
Can I take it with antibiotics?
Space them several hours apart rather than taking them together, and speak to your doctor.
Do I need this if I already take a greens powder?
Possibly not. Several greens powders and Micro Factor already include probiotics at comparable counts. Check before doubling up.
