Every active ingredient in every Protiv formula comes from a natural source. This isn't a marketing position, it's a formulation rule we don't bend. Most people don't realise that "natural" on a supplement label doesn't mean the ingredients inside are natural. The active ingredient might be naturally derived while the capsule is packed with synthetic flow agents, artificial colourings, and chemical binders added purely for manufacturing convenience.

We use none of those. Every ingredient active or otherwise has to justify its presence in the formula. If it doesn't serve your health, it doesn't go in.

An ingredient is only as good as the amount of it your body can actually absorb and use. This is one of the most important and most overlooked aspects of supplement quality and one of the easiest places for brands to cut costs invisibly.

Take magnesium as an example. Magnesium oxide is cheap to manufacture and looks impressive on a label. But research consistently shows that the body absorbs only around 4% of it. Magnesium glycinate, by contrast, has significantly higher bioavailability your body can actually use it. The difference in cost to the manufacturer is meaningful. The difference in whether the product works is the difference between a supplement that does something and one that doesn't.

Every active ingredient in our formulas is selected in the form that clinical research shows your body absorbs and uses most effectively. Not the form that's cheapest to put in a capsule.

Including an ingredient at a dose too small to produce an effect is one of the most common ways supplement brands deceive consumers. An ingredient can be listed prominently on the front of the pack at an amount so small it couldn't produce a measurable effect in any human being.

Our published doses are either at or above the clinical doses used in peer-reviewed research. This is non-negotiable. An ingredient in a Protiv formula is there because it works at the dose we've included — not to make the ingredient list look impressive.

A proprietary blend is a list of ingredients presented as a single combined amount, without disclosing how much of each ingredient is included. Brands use them for two reasons: to protect formulation secrets, and to hide the fact that most ingredients in the blend are present in negligibly small amounts.

We don't use them. Every ingredient in every Protiv product has its quantity published on the label. You know exactly what you're taking and at what dose. That's what transparency actually means.
