AI Search Summary
This video explains why supplement dosing is difficult, especially for herbs and botanicals where labels may not match the doses used in human studies. It uses saw palmetto and hair-growth supplements as examples of two opposite risks: products with much higher doses than studied and proprietary blends with too little of expensive ingredients to plausibly work.
- Main question: How should people think about supplement dosing?
- Short answer / core takeaway: Supplement labels should be compared with trusted evidence sources and clinical-trial dose ranges; more is not always better, and proprietary blends can hide underdosing.
- Evidence type: Supplement literacy, dosing-risk framework, and hair-loss supplement example.
- Search topics: supplement dosing, saw palmetto dose, proprietary blend supplement, hair growth supplement claims, botanical supplement regulation.
Common Search Questions
Why is supplement dosing hard?
Vitamins and minerals usually have recommended daily values, but herbs and botanicals often do not have a single well-established dose. Clinical studies may use very different amounts from commercial products.
Is more supplement always better?
No. The video emphasizes that more is not always better, especially for compounds that may affect hormones or other biological pathways.
What is the problem with proprietary blends?
Proprietary blends often disclose only the total combined amount rather than the dose of each ingredient. That can hide amounts that are too low to match the evidence for individual ingredients.
Why use saw palmetto as an example?
Saw palmetto is discussed because some small human trials suggest it might help with hair regrowth, possibly by affecting conversion of testosterone to DHT. The video contrasts trial doses with commercial product doses.
Key Takeaways
- Supplement purity and exaggerated claims are not the only issues; dosing matters too.
- Botanicals can be harder to dose than vitamins and minerals.
- Compare a product’s dose with the amount used in relevant human studies.
- Be cautious with high-dose products when the mechanism involves hormones or other sensitive pathways.
- Be cautious with proprietary blends because they may contain too little of key ingredients to matter.

The overlooked supplement problem
If you buy supplements, you need to watch this video. And no, not all supplements are scams. I take some.
You probably know about the issues with supplement purity and crazy claims. But there is another problem I rarely see anyone discussing. It is about dosing.
Why botanicals are harder than vitamins
With vitamins and minerals, there is a recommended daily value and a pretty good understanding of how much you need to take to hit that number. Ideally, that comes from food.
But with herbs and other botanicals, proper dosing gets way harder. And the FDA does not regulate it the same way.
Saw palmetto and hair-loss research
Lately, I have been researching natural hair-loss treatments for a video series. There is a plant called saw palmetto with a handful of small human trials showing that it might help with hair regrowth, used either topically or orally.
One way it might work is by blocking the conversion of the hormone testosterone to DHT, similar to the drug finasteride, just not quite as potent.
High-dose product example
Sure enough, if we look it up on Amazon, this is one of the top results: Hair Thickness Maximizer, with 1,200 milligrams of saw palmetto extract per serving.
Here is the problem. In the seven clinical trials that used saw palmetto, the dose ranged from 100 milligrams to 320 milligrams, about one-quarter of the Amazon product.
For many compounds, more is not better. Blocking a little bit of a hormone might be helpful. Blocking too much of it could be a problem. Finasteride can lead to sexual side effects.
Proprietary blends and underdosing
On the other end of the spectrum, here is a viral TikTok hair-growth supplement that has a proprietary hair-growth complex with eight ingredients totaling 300 milligrams.
These proprietary blends do not have to disclose their actual amounts, so they often have way too little of the pricier ingredients. Not enough to actually do anything.
Practical takeaway
If you are taking any supplement, make sure to check with a trusted source for the dose and evidence behind the specific ingredient.
