Assess Nutrient Deficiencies and Measure Success
When there is a reason a client cannot get enough of a nutrient from food itself, that's a good indication for a supplement. When something can be measured, I always feel safer recommending a supplement, since often these come in larger doses than are naturally present in food, or in a form not present in nature. Specifically, I have seen a lot of success with iron supplements used in runners—especially female runners. We can measure iron using blood work. However, sometimes 'anemia' isn't just from iron deficiency. So, in many cases, additional supplementation is needed to correct a documented anemia, aside from iron alone, in runners who are not consuming enough total daily calories. Success is seen when the supplementation can correct a measured deficiency.
Understand Goals and Measure Outcomes
To assess the effectiveness of a supplement in someone's plan, you need first to have a very clear understanding of the goal.
For example, a client may have heard that consuming a curcumin supplement might be beneficial for lowering inflammation. But if there's no evidence of high levels of chronic inflammation, adding this supplement to their intake may not be necessary.
So, when you understand their goals, you then have a clear outcome you can measure against.
A common one in my practice is helping plant-based clients increase their protein intake. Vegans have a limited choice of high-quality protein sources as they don't eat meat, fish, seafood, or dairy.
While tofu is an excellent protein source, it can be challenging to eat this every day.
So, I generally recommend consuming a plant-based protein powder alongside their breakfast and dinner to provide a strong foundation of protein intake that takes the pressure off the meals.
In this instance, measuring effectiveness comes in many different forms:
- Do they feel fuller for longer?
- Do they feel more energy?
- Are they recovering better from their exercise?
A recent client of mine was struggling to get enough protein. They were a plant-based ultra-runner who had a very carbohydrate-rich diet.
After recommending a few simple swaps to increase protein in their diet, I also recommended a daily protein shake twice a day alongside their breakfast and dinner to see how they fared.
They immediately noticed better energy levels and were recovering quicker from their harder efforts in training.
So, to summarize, to identify the effectiveness of a supplement, it's essential to understand a client's goals; from there, you have something to measure the progress against.
This will look different for each individual, their goals, and the supplement of choice.
Monitor Health Markers and Performance Metrics
To assess the effectiveness of a dietary supplement in a client's nutrition plan, I monitor specific health markers and performance metrics related to their fitness goals, along with any subjective feedback on their well-being and energy levels. For example, in a client aiming to improve joint health, we introduced a high-quality fish-oil supplement and observed significant reductions in joint pain and increased mobility over three months, alongside their regular exercise regimen. This improvement was both a subjective report from the client and an objective measure of enhanced performance in their workout routines.
Conduct Routine Blood Tests for Nutrient Levels
To gauge the success of a dietary supplement, one robust method is undergoing routine blood tests. These tests can reveal the levels of specific nutrients in the bloodstream and show if they have been elevated since the introduction of the supplement. It is scientific evidence that can directly link a supplement to improved health markers.
Whenever alterations in nutrient levels are observed, it usually indicates the body's response to the supplement. Checking bloodwork periodically after starting any new supplement will help in assessing its impact. Make sure to talk to a healthcare provider to understand your blood test results.
Note Changes in Vitality and Well-Being
One can monitor the efficiency of a dietary supplement by noting any observable changes in their overall vitality and well-being. Increase in energy levels can be a clear indication that the supplement is functioning as intended. In addition, changes in the quality of skin, hair, or nails may also be signs that the supplement is beneficial.
It is important to pay close attention to your body's responses during the time period of taking the supplement. Be vigilant about your body's signals and consider keeping a journal to record any physical changes you notice. Share your observations with a healthcare advisor to better understand the effects.
Research Scientific Studies for Supplement Efficacy
Investigating the scientific backing of a dietary supplement is a reliable method to assess its credibility and effectiveness. Researching studies that have been conducted on the supplement can provide insight into its potential benefits as well as any side effects. Scholarly articles and clinical trial results are often available in public databases for those who seek validation before adding a supplement to their regimen.
Understanding the scientific consensus on a supplement gives a strong foundation for an individual's decision-making process. To form an informed opinion about a supplement's worth, take the time to study research findings from trusted sources.
Track Symptom Relief Over Time
Evaluating the efficacy of a dietary supplement often involves tracking the relief of specific symptoms over an extended period. As bodily systems can take time to respond to new supplements, maintaining a consistent usage and observing changes in symptoms or discomfort can be an indicator of success. The gradual disappearance or reduction of previously persistent problems could point to the positive effects of the supplement.
It's essential, however, to give the supplement sufficient time to work and not to expect immediate results. Patience is key in such cases, and keeping a log of symptoms and their severity can provide structured data to analyze the outcomes. Discuss ongoing changes with your healthcare practitioner to ensure the supplement is suitable for you.
Consult Healthcare Professionals for Personalized Advice
To ascertain the advisability and performance of a dietary supplement, consulting with a healthcare professional is highly recommended. A professional can offer personalized advice based on an individual's unique health profile and needs. They can also help in setting realistic expectations and determining if the chosen supplement is the optimal option among available alternatives.
Healthcare experts are equipped to interpret clinical evidence and patient feedback, providing a more comprehensive assessment. Schedule an appointment with a nutritionist or dietitian to get their expert opinion on any new supplement you are considering.
