( ) According to expert organizations such as the International Scientific Association for PROBIOTICS and PREBIOTICS, a probiotic is defined as:

"live microorganisms that, when administered in adequate amounts, confer a health benefit to the host".

This is different than prebiotics (which promote the growth of beneficial organisms, or synbiotics which are products that blend probiotic bugs with prebiotics).

Decades of research have explored different species and strains of microorganism formulations (probiotics) in supporting health, managing symptoms of various disorders and diseases, and the prevention of diseases - amazing.

Any recommendation for a probiotic product should be based on clinical trials that have used a specific strain, or combination of strains at a given dose which have yielded clinically meaningful results.

Visbiome is such a product.

Visbiome is a high-potency probiotic containing 8 strains of bacteria with 450 billion bacteria per dose.

Visbiome has Level 1 evidence and is approved by Health Canada for its recommendation to help manage uncomplicated constipation.

Have you ever used or heard that probiotics could help prevent and manage constipation? Let me know in the comments.

A common myth about chronic constipation is…

It’s simply due to a lack of fiber

This is a common idea that many of my clients/patients have been told by their doctor, the media, Google or their friends; we need to clear up this misunderstanding because it is causing people to lose sight of the bigger picture where gut health and gut function are concerned.

The reason we know this is not true is because centering only on fiber means only focusing on one potential problem while not considering other variables that support gut motility.

The reality is, taking a more integrative approach ensures you’re considering all of your digestive tract needs where building and maintaining gut health and gut function are concerned.

Have you been buying into this myth? Could this be one of the reasons why you have not yet been successful with the bloating and constipation?

If non-medically related constipation was nothing more than a lack of fiber, well, then, millions of people around the world wouldn't be suffering from irregular poops and the problems that come with it.

Negative news featuring findings from poorly designed studies on vitamin D continues to pop into the media spotlight, concluding that vitamin D supplements are useless and ineffective.

The issue has gotten so bad that funding for vitamin D research has become majorly affected,

The late Dr. Robert Heaney’s nutrient study criteria when approaching published nutrient research to determine what amount of validity the study conclusions hold.

Nutrients don't act in isolation and using the classic RCT drug model of nutrients isn't the best.

So ahead of the times and either researchers are unaware of these criterion or know and ignore, either scenario is worrisome.

Optimizing your vitamin D status is one of the best things you can do for your overall health. No one dose for everyone, take what you need to get your vitamin D to at least 75 nmol/L or 30 ng/ml - supplement and get tested

Robert Heaney's awesome article:

A 2023 Neurology Reviews article titled “Global burden of brain disorders surpasses cardiovascular disease & cancer” highlighted findings from the Global Burden of Disease (GBD) study. They found that brain disorders [mental illness, neurologic conditions, & stroke], now account for more than 15% of all health loss worldwide – a number that now surpasses that from either cardiovascular disease or cancer.

Based on clinical advice we need 1.6g per kg of body weight, or approximately 0.73 grams of protein per pound.

And as we age we NEED to increase protein.

So if you’re over 60, your intake should go up to 2g per kg of body weight or approximately 0.91 grams of protein per pound.

That’s a lot!

Do you know what your vitamin D level is? ⁣

If not, you may want to get it tested. I've had my done the traditional way via an in-lab blood draw and I've used at-home bloodspot tests like this one by ⁣
(no affiliation). ⁣

Because vitamin D levels vary from person to person, you don't know what your personal dose may be AND because there are other factors that influence vitamin D levels such as ⁣

- body size ⁣
- taking a vitamin D supplement with food vs on an empty stomach ⁣
- intake of other nutrients such as vitamins B6 and B12, magnesium, calcium, vitamin D, and vitamin K2, ⁣
- age ⁣
- digestive health issues ⁣
- genetics ⁣
- medications ⁣

The only way to know what dose is right for you is to test. I like to leverage at home testing from time to time, if you want to do the same, that's your call. ⁣

Always best to check with your healthcare practitioner, doctor etc to decide what's best for you ⁣

Pumpkin seeds, how I love thee, let me count the ways..." Here are five reasons why pumpkin seeds are considered healthy:

Nutrient-Rich: Pumpkin seeds are a powerhouse of nutrients. They are a rich source of essential minerals such as magnesium, potassium, zinc, and iron. These minerals play crucial roles in various bodily functions, including immune support, bone health, and energy metabolism.

High in Antioxidants: Pumpkin seeds are loaded with antioxidants, including carotenoids and vitamin E. Antioxidants help protect the body's cells from damage caused by free radicals, which are unstable molecules that can contribute to various chronic diseases and aging.

Heart Health: Pumpkin seeds contain a good amount of heart-healthy monounsaturated and polyunsaturated fats, as well as phytosterols. These compounds have been associated with a reduced risk of cardiovascular diseases by helping to lower cholesterol levels and improve overall heart health.

Rich in Protein: Pumpkin seeds are an excellent plant-based source of protein. Protein is essential for building and repairing tissues, supporting muscle health, and maintaining a healthy immune system. Including pumpkin seeds in your diet can be particularly beneficial for individuals following vegetarian or vegan lifestyles.

Mood and Sleep Support: Pumpkin seeds contain the amino acid tryptophan, which is a precursor to serotonin and melatonin—neurotransmitters that play key roles in regulating mood and sleep. Consuming foods rich in tryptophan, like pumpkin seeds, may contribute to improved mood and better sleep quality.

Incorporating pumpkin seeds into your diet can be a tasty and nutritious way to enjoy these health benefits. Whether sprinkled on salads, added to yogurt, or eaten as a snack, pumpkin seeds can be a versatile and enjoyable addition to your meals.

I'm on a vitamin D roll.

Vitamin D plays a critical role in protecting humans from invasive pathogens (bacterial and viral), reducing risks of autoimmunity, and maintaining health.

Conversely, low 25(OH)D status increases susceptibility to infections and developing autoimmunity.

Systematic reviews/meta-analyses strongly suggest that maintaining serum 25(OH)D concentrations at or above 125 nmol/L [50 ng/mL] is associated with significant risk reduction from viral and bacterial infections, sepsis, and autoimmunity. Most adequately powered, well-designed, randomized controlled trials with sufficient duration supported substantial benefits of vitamin D.

Virtually all studies that failed to conclude benefits or were ambiguous had major study design errors. Treatment of vitamin D deficiency costs less than 0.01% of the cost of investigation of worsening comorbidities [diseases, disorders, symptoms] associated with vitamin D inadequacies, insufficiency.

Virtually all studies that failed to conclude benefits or were ambiguous had major study design errors. Treatment of vitamin D deficiency costs less than 0.01% of the cost of investigation of worsening comorbidities associated with hypovitaminosis D ["vitamin D inadequacies, insufficiency."].

Those with gastrointestinal malabsorption, obesity, or on medications that increase the catabolism of vitamin D and a few other specific disorders require much higher intake. This systematic review evaluates non-classical actions of vitamin D, with particular emphasis on infection and autoimmunity related to the immune system.

More vitamin D fears debunked.....Since vitamin D has a higher affinity for fat, some have speculated that vitamin D can build-up in our body fat over time and become toxic. Additionally, the question has been raised that individuals who are overweight and obese might be at particular risk when taking vitamin D supplements of vitamin D toxicity if they lose a large amount of weight in a short period of time. However, Vitamin D build-up in body fat does not continue indefinitely. When there is a continuous supply of vitamin D, a balance is reached between the vitamin D stored within our body fat and its removal for use into the blood stream.

Yesterday, we addressed our first vitamin D myth – that, being fat soluble, vitamin D can be stored in our fat cells for later use. We have heard concerns that supplementation with vitamin D is not needed, or even safe, because of this. While it is true that vitamin D has a higher affinity for …

Don't wait! Start today.

Be one of THOSE people [like me] who seem to not get sick or have mild cases when they do.

The immune system is constantly working to protect the body from infection, injury, and disease.

It relies on an adequate supply of nutrients for its baseline functions as well as for ramping up its activity when necessary.

It is well established that malnutrition (protein-energy malnutrition and obesity) and deficiencies in one or more micronutrients (vitamins and nutritionally essential minerals) diminish immune function.

In most instances, correcting the nutrient deficiency restores the affected immune functions.

A lot of people freak out over juices, worrying about sugar and liquid carbs etc

Many of these same people will have higher carb containing foods like pasta, rice, potatoes, etc or have toast and jam with their breakfast

Freshly pressed vegetable and/or fruit juices CAN be part of a healthy diet.

Growing up, juice used to 100% fruit juice and a serving was 1/2 cup or 4 oz. Today, people often drink more juice than they 'need' and the liquid calories add up

Carrot juice offers a lot of concentrated carotenoids which is why I have it regularly and you don't need much to get the benefits.

If you're worried about 'fast absorbing carbs', consume it wilh a meal and get on with your day, you've got a lot of living to do and bigger things to worry about

If I'm not consuming my carrot juice with a meal (that has fat), I add about 1 Tbsp of olive oil and give it a stir.

Consuming carotene-rich foods with a source of fat GREATLY enhances the absorption of said carotene....got it?

New Data Suggests Previous Vitamin D Supplementation Trials May Have Missed the Mark

Why is this Important?

According to the authors, an estimated 40% of the US population have vitamin D levels below 20 ng/ml (50 nmol/L). This is in combination with the current recommended dietary allowance of vitamin D being a mere 600-800 IU/day — way too low to avoid vitamin D deficiency.

Viet Le, DMSc, PA-C, discusses early data from the Target-D trial and how this might influence the way he interprets the findings from other vitamin D supplementation studies.

Exercise, activity, and so really is the best 'medicine' when it comes to improving, and maintaining metabolic health. Walking IS good, but if possible, aim to get some activity that is a tad more demanding to make your cells (mitochondria) better fuel burners and energy producers

Exercise that’s easy, but not too easy, can improve your fitness and your metabolic health. Here’s how to do it.
