Did you know that your body contains TEN times more bacteria than human cells?! Most of them live in the gut, and they can have a surprising impact on the rest of your body.

Probiotics can help to keep your gut bacteria balanced, which is why many people are turning to probiotic supplements to boost their digestive health and their overall well-being. In this article, we’ll talk about what probiotics are, how they work, and what benefits you can expect from organic supplements like our Feel Supreme Inner Purity Probiotic Formula.

What are probiotics?

First, let’s talk about those gut bacteria. Together with other microorganisms like viruses and fungi, the bacteria in your gut make up a community called the gut flora or microbiome. This is mostly located further along your digestive tract in the large colon.

Your microbiome plays lots of essential roles, like creating vitamin K and some B vitamins. It also turns fibres into certain types of fats needed to strengthen the gut wall and keep your metabolic and immune systems functioning properly.

Some bacteria in the microbiome have the potential to be harmful, but in a healthy gut, they’re kept in check by commensal or “friendly” bacteria. However, if your friendly bacteria levels drop, the harmful bacteria can multiply and start to wreak havoc on your body.

An imbalance in gut flora can happen due to poor diet, antibiotics, or illness. It’s been linked to a number of serious illnesses like:[1][2][3][4]

  • Obesity
  • Heart disease
  • Type 2 diabetes
  • Metabolic syndrome

Probiotics can prevent or correct bacterial imbalances in the gut by boosting the numbers of good bacteria.[5] Some foods are natural sources of probiotics, especially fermented foods like yoghurt, pickled vegetables, kimchi, tempeh, miso and sauerkraut. But if you’re not getting enough probiotics from your diet, you can take a supplement too.

What are probiotic supplements?

A probiotic supplement is usually a capsule or a drink containing large numbers of friendly bacteria. Some feature a single bacteria group (most commonly Lactobacillus, Saccharomyces or Bifidobacterium), while other “broad-spectrum” or “multi-strain” supplements feature a combination.

Probiotics are not to be confused with prebiotics. Rather than putting bacteria back into your body like probiotics do, prebiotics are designed to feed the bacteria that are already there.

What are the benefits of probiotic supplements?

There are lots of different strains of bacteria and they each have different effects on the gut microbiome. There are far too many strains to go into each one, but here are some of the most widely studied benefits. You can find out more about the associated strains in the references.

  1. Can reduce symptoms of some digestive conditions

Not surprisingly, the balancing effect of probiotics on your gut microbiome is shown to have several proven digestive health benefits.

First, probiotic supplements are known to prevent and treat antibiotic-induced[6], infectious,[7] and other types of diarrhoea.[8] There’s also evidence that they can relieve the symptoms of digestive disorders like ulcerative colitis and irritable bowel syndrome.[9][10]

  1. May help weight loss

There’s growing evidence that certain probiotics can help you to lose weight.[11] Some strains are thought to prevent you from absorbing fat in the digestive tract,[12] while others are believed to boost calorie burning, prevent fat storage, and make you feel fuller for longer.[13][14] However, strains like Lactobacillus acidophilus may cause weight gain,[15] so if weight loss is your goal, it may be better to avoid this strain.

  1. May promote heart health

Some studies have shown that probiotics have a positive effect on cholesterol, lowering the “bad” LDL variety[16] and, in some cases, increasing “good” HDL cholesterol.[17] A series of studies also found that probiotics can lead to a small but notable reduction in blood pressure.[18]

  1. May support mental health

Often called the second brain, we’re increasingly finding that the gut can have a big impact on our mood, too. Some studies[19][20][21] have found that probiotic supplements can improve the symptoms of:

  • Depression
  • Anxiety
  • Stress
  • Obsessive compulsive disorder (OCD)
  1. May support immune health

By restoring balance in the gut microbiota, probiotics can prevent the growth of harmful gut bacteria.[22] The immune benefits extend beyond the gut, though. Some strains are also believed to help fight respiratory infections[23] and significantly reduce the frequency and severity of urinary tract infections (UTIs) in women.[24] Other probiotics have also been found to boost production of the body’s natural immune cells and antibodies.

How do I take probiotic supplements?

We recommend taking probiotic supplements in capsules rather than drinks. The bacteria have to make it all the way to your large intestine in order to work their magic, but they can be killed by stomach acid and bile along the way. Drinks offer little protection for the bacteria, but a capsule will ensure they reach the large intestine alive and well.

It’s also important to take probiotics at a high-enough dose. Probiotics are measured in colony-forming units, or CFU, and depending on the bacteria strain, you’ll need a dose of at least two billion CFU to see the benefits (the higher the better!).

Are probiotics safe?

Yes. Probiotics are generally safe, although you should always ask your doctor if you have a pre-existing condition and/or you take medication.

Follow the recommended dosage on the packaging for best results, but don’t worry if you take too many. A study tested the effect of a 1.8 trillion CFU dose of probiotics and found that no harm was done.[25]
