Vigorus Blog: Ingredient Reads for Careful Buyers

Quick answer

The Vigorus blog has six new and featured posts, with three more added on October 30, 2026. One compares citrulline study doses of 3 to 9 grams with the 570 mg blend. One checks the 20 mg niacin and 11 mg zinc against daily limits. One reviews the small trials on saffron and maca. Each post cites its sources.

Why do the blend numbers matter so much in these posts?

Because four of the six figures a buyer wants are hidden. The label gives one total for the blend and nothing for its parts.

  • 570 mgBlend total per capsule
  • 6Ingredients sharing it
  • 0Individual amounts printed
  • 3 gSmallest citrulline dose in the studies

Even if the whole blend were citrulline, it would reach less than a fifth of the lowest study dose. It is not all citrulline, so the real share is smaller still. Each post keeps this gap in view instead of hiding it.

How can you check a post against your own bottle?

The posts quote the label, but your bottle is the final word. Four quick checks take about two minutes.

  1. Find the Supplement Facts panel

    It is on the side of the bottle, next to the suggested use and caution text.

  2. Match the two printed amounts

    Look for Vitamin B3 (as niacin) 20 mg and Zinc (as zinc oxide) 11 mg.

  3. Read the blend line

    It should show 570 mg and list the six ingredients by name, with no amounts beside them.

  4. Note the lot number

    Compare it with the reference VIG-26/TH-4172. It is a matching label, not a lab result.

How does each post's label amount compare with the research?

This table sums up the core comparison in each post. The right column names the main source.

How is a Vigorus blog post put together?

Every post goes through the same five steps before it is published. The steps keep label facts and research facts apart.

  1. Copy the label line

    The writer starts from the Supplement Facts panel and records the amount exactly as printed, or notes that it is not published.

  2. Find the research dose

    Study amounts come from NIH fact sheets, systematic reviews or controlled trials, never from marketing pages.

  3. Put the two side by side

    A table or plain sentence shows the gap, if any, between the capsule and the studies.

  4. Quote claims as claims

    Anything the sales page says is marked as the seller's words and kept out of the conclusions.

  5. Check the wording

    Short sentences, no disease claims, no promised timelines, and every source listed at the end.

Where can you read about the other three blend ingredients?

The blend holds six ingredients, and three have their own posts so far. The other three are covered on the ingredients page for now.

L-carnitine

Studies mostly used 1 to 3 grams a day (NIH ODS). The body also makes its own supply.

Pine bark extract

Pycnogenol has 39 controlled trials across several health areas (Weichmann et al., 2024). The amount in this blend is not published.

Grape skin extract

Grape skin is a source of resveratrol and related plant compounds. The label does not state which compounds or how much.

Which order should a first-time reader follow?

If you plan to read all three posts, this order builds from simple to complex.

  1. Zinc and niacin first

    These are the only two amounts printed on the label, so they are the easiest to judge.

  2. Citrulline second

    This post explains why a proprietary blend makes dose comparisons hard.

  3. Saffron and maca last

    With the dose problem in mind, the thin evidence on these two makes more sense.

Then open the Supplement Facts page and compare what you learned with the bottle.

What language will you never see on this blog?

The posts avoid wording that suggests more certainty than the research gives. Here is what that rules out, and what replaces it.

Pros

  • "The sales page says" before any product claim
  • "Not published" for missing amounts
  • Named sources with links
  • Plain ranges such as 3 to 9 grams

Cons

  • Promises of results or dates
  • Claims to treat or cure any condition
  • Invented reviews, experts or studies
  • Words like "miracle" or "proven"

How do you know a post is current?

Each post shows a last-updated date under its title. This index was last checked on October 30, 2026.

Posts are revised when the label changes, when a cited source updates, or when a reader reports an error. The date moves only when the content does.

Should a blog post replace advice from your doctor?

No. The posts explain ingredients; they cannot weigh your health history. Citrulline and pine bark both touch circulation, so anyone on blood-pressure, blood-thinning or nitrate medicine should show the label to a clinician before starting.

For the full list of cautions, read the side effects page.

Questions about the Vigorus blog

How many posts are on the blog?

Three right now: citrulline, zinc and niacin, and saffron and maca. New posts are added to this index when they go live.

Why is there no post on carnitine, pine bark or grape skin yet?

Those three are covered on the ingredients page. A separate post will follow only if there is enough solid research to fill one honestly.

Do the posts say whether the product works?

No. They compare label amounts with research amounts. No study has tested the finished capsule, so the posts do not claim a result.

Who writes the posts?

The Vigorus Editorial Team, the same team behind the rest of the site. No outside expert is quoted, because none has reviewed this product for us.

How do I request a post on a new topic?

Yes. Send it to the website inbox. Topics tied to a label ingredient or a common buyer question get priority.

Are the posts sponsored?

Thevigorus earns money when you buy through this site, and the posts link to the order page. That is why every post sticks to label facts and cited sources.
