Multi-ingredient supplements promise convenience, while single-ingredient products promise precision, and most buyers are never told how to choose between them. The decision matters, since it affects what you can measure, what you spend, and what you actually take each day. I sell both kinds of products, so I have a stake in both answers. Here I explain what research shows about combinations, how nutrients can affect one another, and when a single ingredient is the better tool. I also explain how I think about my own combination formula, including what its research cannot tell you.

Single vs multi-ingredient supplements: a researcher explains when each makes sense, what combination trials show, and how nutrients interact.

🧠 When Should You Consider the ADAS-Cog Test?
Your memory and brain health deserve attention; not guesswork.

Have you or someone you love noticed changes in memory, language, or thinking? It may be time to speak with a healthcare professional about a cognitive evaluation.

The ADAS-Cog (Alzheimer’s Disease Assessment Scale–Cognitive Subscale) is a structured assessment that measures aspects of cognitive performance, including memory, language, and other thinking abilities. It is used extensively in Alzheimer’s research and clinical trials to measure cognitive changes.

When might it be considered?
- 🧠 Increasing forgetfulness: Repeatedly asking the same questions or forgetting recent conversations.
- 💬 Language changes: Increasing difficulty finding familiar words or following conversations.
- 📉 Changes in everyday thinking: Growing difficulty with planning, organizing, or familiar tasks.
- 👨‍⚕️ Monitoring cognitive changes: A clinician may use structured assessments to measure changes over time, depending on the clinical setting.

Why does early evaluation matter?
Recognizing changes early can help identify possible causes, guide further testing, and support timely care and planning. Not all memory problems indicate Alzheimer’s disease; some causes may be treatable.

Important: The ADAS-Cog is not a stand-alone test for diagnosing Alzheimer’s, and it is not generally the first-line screening test in routine primary care. A healthcare professional can determine whether it or another cognitive assessment is appropriate.

💚 Your brain health matters. Don't ignore persistent changes. Start the conversation with your healthcare provider.

🍚 WHAT IF THE BEST PART OF RICE IS THE PART WE THROW AWAY? 🌾

Most people reach for white rice, but the layer that gives brown rice its color is the most nutritious part, rice bran!

Dr. John E. Lewis explains that this bran is often stripped away and discarded or used for animal feed, while the white rice underneath is still eaten.

His point? We may be overlooking a valuable part of the plant when we choose white rice over brown.

🌱 Next time you order rice, will you choose brown or white?

🎥 Watch Dr. Lewis break down the difference.

Liposomal curcumin costs more than plain curcumin, and the reason given is always absorption. Every product page in this category prints a multiple and treats the matter as closed. Those multiples come from real human studies, and they are far more fragile than the labels suggest. I will cover what curcumin is, why so little of it reaches your blood, and what a liposome does. I will also cover the forms on the shelf, the amounts people take, and the safety record. You will finish this article able to read an absorption claim, mine included, and price it honestly.

Liposomal curcumin is sold on absorption numbers. I explain what the human trials measured, where they agree, and where they do not.

Vitamins D3 and K2 appear together on more supplement labels every year, and almost nobody explains why. Shoppers see the pairing, assume the science is settled, and buy on that assumption. The mechanism behind the pairing is real and well described. The clinical evidence for the pair is thinner than the marketing suggests. This article covers what each nutrient is and why the two are combined. It also covers what the trials measured, how much people take, and what the safety record shows. You will finish it able to decide whether the combination belongs in your own routine, and at what amount.

Vitamin D3 and K2 are sold as a pair. I explain the mechanism behind that pairing and what the trials have actually measured.

🌱 Soy Gives You Protein… Not “Man Boobs.” 😂

Let’s clear up a common soy myth.

Dr. John E. Lewis explains that phytoestrogens are not the same thing as estrogen. Phytoestrogens are naturally occurring plant compounds found in soy and many other plants.

So before you write tofu off, take a closer look at the science. 🧪

🥢 Tofu. Tempeh. Fermented soy. Plant-based protein worth understanding.

A proprietary blend is the single line on a supplement label that tells you the least, and my own flagship formula uses one. If you have read the criticism, you know the concern: a blend hides how much of each ingredient you are getting. That concern is fair, and I will not try to argue you out of it. Below, I set out what a proprietary blend is, what federal labeling rules require, and what independent laboratory research has found. I will also show you what my own label discloses, what it withholds, and what you can check instead.

What is a proprietary blend? I explain what the label hides, what lab testing shows, and why my own formula stays proprietary.
