This is a free micro-learning course, which means a short, structured learning experience built around a single topic rather than a full curriculum. In six focused lessons you will work through what the human research actually shows for protein powder, creatine, caffeine, beta-alanine, BCAAs, glutamine, testosterone boosters and fat burners. Every claim is tied to systematic reviews and meta-analyses, and every lesson separates what is well supported from what is oversold.
Educational notice: This course is health education only. It does not provide medical advice, diagnosis, treatment or individualized supplement recommendations, and it does not endorse any product or brand. Consult a qualified healthcare provider or registered dietitian before starting, stopping or changing any supplement, particularly if you are pregnant or breastfeeding, under 18, managing a health condition such as kidney disease, or taking medication.
The supplement industry is very good at telling you that a plausible mechanism is the same thing as a proven result. A compound activates a pathway in a cell culture, or nudges a hormone in a small trial, or increases fat oxidation for ninety minutes, and that becomes a product claim about your physique.
This course works through six categories in order of how strong the evidence actually is, so you finish with a realistic ranking rather than a shopping list. Along the way it deals directly with the questions people are usually too embarrassed to ask: whether protein harms your kidneys, whether creatine causes hair loss, whether the beta-alanine tingle means anything, and why a fat burner that feels powerful may simply be adulterated.
A nutrient can be biologically necessary without providing any additional benefit when you already eat enough of it.
BCAAs are essential amino acids. Glutamine is the most abundant free amino acid in your blood and muscle. Both are genuinely important to human physiology, and both are usually poor supplement purchases for a healthy person already eating adequate protein.
That gap between “important in the body” and “useful in a tub” is one of the most reliable places supplement marketing goes to work, and once you can see it you will see it everywhere.
One of the first things the course does is sort these products by the strength of the human evidence behind them, rather than by how loudly they are marketed.
Decades of randomized trials and multiple meta-analyses behind them. The benefits are real, reasonably consistent, and consistently smaller than the advertising suggests. The course covers what each one does, who actually needs it, and where the returns flatten out.
A legitimate but event-specific supplement. It has clear effects on muscle carnosine and meaningful benefits for certain hard, sustained efforts, while showing little for short sprints, maximal strength or body composition. Matching it to the demand is the whole skill.
Strong biological stories, weak practical value for people already eating enough complete protein. The course explains why activating a muscle-building signal without supplying the full set of building materials produces an incomplete response.
The least supported categories on the shelf, and the ones most frequently found to contain undeclared pharmaceuticals. The course walks through the common ingredients one at a time and explains what contamination data means for anyone in a tested sport.
No science background, nutrition coursework or research training required. Every technical concept is explained as it comes up.
The course is free, so the quickest way to judge the teaching style is to enroll and read the first lesson.
The goal is not to memorize a list of good and bad products. It is to evaluate the next supplement claim you encounter, including ones that do not exist yet.
Rank supplements by evidence quality rather than by marketing volume, using systematic reviews and meta-analyses as your reference point.
Judge whether protein supplementation is useful for you based on your total daily intake, where diminishing returns begin, and whether food already covers it.
Evaluate creatine claims accurately including loading, timing, expensive alternative forms, kidney markers, hair loss and the limits of female-specific research.
Use caffeine strategically by understanding dose response, individual variation, tolerance, and the trade-off between today's session and tonight's sleep.
Match a supplement to an energy system so you can tell when beta-alanine is relevant to your event and when creatine is the better fit.
Recognize redundant purchases by comparing an isolated ingredient against an adequate serving of complete protein rather than against nothing at all.
Interpret hormone and fat-oxidation claims and explain why a small testosterone change or a temporary rise in fat burning does not predict muscle gain or fat loss.
Assess product quality and contamination risk using proprietary-blend red flags, adulteration data and third-party certification, and know what certification does not prove.
Open any item below to see what it covers. The lessons move from the strongest evidence to the weakest, which is the opposite of how most supplement marketing is ordered.

A realistic scenario built around a fictional person, fictional products and invented label data. You work through the same reasoning a careful consumer would: what is in this, what dose, what does the evidence support, what is missing, and what would you actually recommend.
Rather than trusting the course, you go verify it. The guide explains how deep research modes differ from ordinary chatbot conversation, how to write a prompt that returns citations you can actually check, and which free alternatives work if you do not want a subscription.
Want more structured practice reading studies? Module 9 of the Complete Health & Wellness Course covers source quality, reading a study abstract without a science degree, and separating evidence from marketing.
Built so you leave with a method for evaluating supplements, not just a verdict on six of them.
Protein, creatine, caffeine, beta-alanine, BCAAs and glutamine, and the testosterone booster and fat burner categories, ordered by evidence strength.
Each lesson ends with supported conclusions and a list of specific marketing claims the evidence does not back, so you can find an answer fast later.
A fictional scenario with invented products, guided question by question through a free AI assistant with feedback on your reasoning.
Tiered investigation prompts plus instructions for verifying citations yourself through PubMed, journal DOIs and regulator databases.
More than sixty peer-reviewed citations with DOIs, weighted toward systematic reviews, meta-analyses and position stands.
Plain-language definitions for terms such as ergogenic, ergolytic, dose-response, adulteration, proprietary blend and lean body mass.
How third-party certification works, what it does and does not prove, and which product categories carry documented contamination risk.
Come back whenever a new product lands in your feed, and receive future revisions at no cost as the research updates.

He built this mini-course because supplement questions come up in every class and every conversation, and because the honest answers are rarely the ones being advertised.
There are no affiliate links in this course, no brand recommendations, no discount codes and nothing to buy. The conclusions are drawn from systematic reviews and meta-analyses, including the ones that undercut popular supplements, and the lessons note industry funding and author conflicts of interest where they exist.

All six instructional lessons are self-contained reading. You can finish them and walk away with the core concepts without ever opening an AI tool.
The two applied activities are different by design. The case study document is written to be attached to a free AI assistant such as ChatGPT, Gemini, Claude, Copilot or Qwen, which then presents the scenario and works through the questions with you. The deep research investigation uses research or deep research modes, and the guide points out which platforms offer free queries along with manual alternatives through PubMed and Google Scholar.
The course is equally direct about where these tools fail. AI can fabricate citations, misjudge study quality and state weak findings with unearned confidence, which is exactly why the investigation guide insists you click through to the original source before believing anything, including anything the course itself told you.
Supplement claims are one instance of a much larger pattern. These courses take the same reasoning further.
The natural companion. Learn how fitness and supplement marketing is constructed, how to spot bad advice and outright scams, and which persuasion tactics reappear in every wellness sales page.

A micro-learning course is a short, structured learning experience built around a single focused topic. Instead of a broad multi-module curriculum, you get a small number of sequenced lessons with clear outcomes and applied practice.
Protein powder, creatine, caffeine, beta-alanine, BCAAs and glutamine each get a dedicated lesson. The final lesson covers the testosterone booster and fat burner categories, working through common ingredients including tribulus, D-aspartic acid, fenugreek, ashwagandha, tongkat ali, green tea extract, synephrine, yohimbine, L-carnitine, CLA, capsaicin, chromium, garcinia and raspberry ketones.
No, and that is deliberate. The course explains what the evidence supports, for whom, and under what conditions, so you can reason about your own situation and ask better questions.
Individual recommendations depend on your health history, medications, diet, training and goals, which is territory for a healthcare provider or registered dietitian rather than a course.
No. There are no brand recommendations, product reviews, affiliate links or discount codes anywhere in the course. It does explain what to look for on a label, why proprietary blends are a problem, and how independent third-party certification programs work.
The lessons describe the intake ranges used in published research on healthy adults, because you cannot evaluate a claim without knowing what dose produced it. Each of those discussions carries an explicit disclaimer that research ranges are not medical recommendations and may not suit everyone.
Anyone with kidney disease, a metabolic condition, a pregnancy, or a relevant medication should talk to a clinician before changing their intake of anything.
No. Terms like dose-response, ergogenic, meta-analysis, adulteration and lean body mass are explained in plain language as they appear, and each lesson ends with a glossary.
The six lessons take roughly an hour to ninety minutes of reading in total. The case study typically adds 20 to 30 minutes, and the deep research investigation can take 30 to 60 minutes per question depending on the tool you use.
It is self-paced with lifetime access, so there is no deadline and no need to do it in one sitting.
No. Much of the research comes from sport and resistance training contexts, but the content is written for anyone who buys supplements. The protein lesson covers older adults and sarcopenia, the creatine lesson discusses cognition and the limits of research in women, and the final lesson is relevant to anyone who has considered a weight-loss product.
Yes. The final lesson reviews published analyses of undeclared pharmaceutical ingredients in dietary supplements, explains which categories are most frequently implicated, and discusses strict liability for tested athletes. It also explains what third-party certification reduces, and what it cannot prove.
Not for the lessons, which are complete on their own. The two applied activities are built around free AI assistants, though you can work through the case study on paper and do the research investigation manually through PubMed or Google Scholar if you prefer.
No. This is personal health education. It does not provide a fitness, nutrition, medical or healthcare credential, and it does not qualify anyone to recommend supplements to clients.
Each lesson closes with a full APA reference list drawn largely from systematic reviews, meta-analyses and position stands in journals such as Sports Medicine, Nutrients, Advances in Nutrition, the British Journal of Sports Medicine, Nutrition Reviews and the Journal of the International Society of Sports Nutrition, along with Cochrane reviews. DOIs are included so you can read the originals.
A few supplements genuinely earn their place. Most of the shelf is selling you a plausible mechanism and hoping you never check whether it produced a result in an actual human being. This free mini-course gives you a structured way to tell the two apart, using the same peer-reviewed evidence the industry quotes selectively.
