Most collagen supplements have something to hide. Not in a sinister sense. But the collagen category is full of products that use proprietary blends, add sweeteners and flavorings to mask poor solubility, or make skin and joint claims without disclosing the amino acid profile that would allow anyone to assess whether those claims are plausible. Ancient + Brave True Collagen has none of those problems. It also raises a question worth answering properly: what does collagen actu

The short answer is: it depends on the product and the flavor. Optimum Nutrition is one of the most searched supplement brands in the protein category. The artificial sweetener question comes up consistently, and the answer is not the same across every product in the range. Here is what CuratedFit found when reviewing the two ON products currently in the catalogue. Gold Standard 100% Whey The flavored versions of Gold Standard 100% Whey contain sucralose and acesulfame potass

The supplement category is full of products marketed as essential daily support. Most of them are not essential. Some of them are genuinely useful. A small number address gaps that diet alone consistently fails to close for most people. The CuratedFit Daily Foundations category exists to make that distinction visible. Here is what belongs in a genuine daily foundation, what the reasoning is, and which products in the catalogue address each gap. The gaps diet alone consistentl

Gold Standard Casein is one of the most searched casein products in the market. The CuratedFit review is one of the closest pages on the site to ranking on page one of Google for that search. Here is the full breakdown of what the review found and what it means in practice. What micellar casein is and why it matters Casein is the primary protein in milk, making up roughly 80% of milk's total protein content. Whey makes up the other 20%. They come from the same source but beha

Gold Standard 100% Whey is one of the most searched protein products on the market. It is also one of the most frequently misunderstood in terms of what is actually in it. People search for the amino acid profile, the ingredient list, whether it contains sucralose, whether it is safe, whether it is third-party tested. Those are exactly the right questions. Here is what the answers actually are, based on the CuratedFit review of the EU formulation. The protein blend: three for

Most protein powders have ingredient lists. Egg white powder from yourhealthstore has one ingredient. That is not a trivial distinction. The supplement market has spent decades adding things to protein products: sweeteners, flavors, stabilizers, anti-caking agents, vitamin blends, until the ingredient list of a standard protein powder bears little resemblance to the food it claims to derive its protein from. A product with one ingredient cannot hide anything in a proprietary

CoQ10 is one of the most commonly taken supplements for energy and cardiovascular support. It is also one of the most inconsistently labeled categories on the market. The confusion comes from one distinction most labels obscure entirely. CoQ10 exists in two forms. Which one is in the capsule changes how the body uses it. The label usually just says CoQ10. Here is what that distinction actually means. Ubiquinone versus ubiquinol Coenzyme Q10, CoQ10, exists in two interconverti

Most vegan muscle building guides solve one problem. Protein. They recommend a plant protein powder, suggest eating more beans and lentils, and call it done. That is not wrong. It is just incomplete. Building muscle on a plant-based diet is not fundamentally different physiology. The body does not care where an amino acid came from once it is absorbed. What is different is which mechanisms are harder to hit by default on a plant-based diet, and which ones a non-vegan diet cov

The conversation around vegan and plant-based sports nutrition tends to start and end with protein. How much, from which sources, whether the amino acid profile is complete. Those are legitimate questions. They are also not the only questions worth asking. There are five nutritional gaps that appear consistently in plant-based athletes, each with a distinct mechanism, and each one that protein powder does nothing to address. Understanding them changes how you think about supp

Most people who take a pre-workout or a creatine scoop assume they are boosting energy in some generic sense. That is not really what is happening. The body does not have one energy system, it has three, each built for a different duration and intensity of effort, and each one runs on different fuel and different supporting nutrients. Understanding which system is doing the work at any given moment is the difference between supplementing with intent and just taking what is po

Green tea extract is one of the most commonly taken supplements in the metabolism and daily foundations category. It is also one where the label figure most people look at, the total polyphenol percentage, tells you less than you might expect. Here is what the CuratedFit Standard found when it reviewed Life Extension Mega Green Tea Extract in the decaffeinated form. The standardization problem with most green tea products Most green tea extract labels show a total polyphenol

L-theanine appears on supplement labels in two distinct contexts. As a standalone calming supplement. And as a caffeine companion, designed to smooth out the jittery edge that caffeine can produce while preserving the alertness. Most labels tell you which role it is marketed for. Very few tell you where the L-theanine actually came from or how it was produced. Here is what the CuratedFit Standard found when it reviewed Life Extension L-Theanine AlphaWave. Where L-theanine act

Lion's Mane is one of the most searched nootropic ingredients of the past two years. It is also one of the most inconsistently labelled supplement categories on the market. The inconsistency is not random. It follows directly from a production shortcut that a significant proportion of Lion's Mane products use, one that lets a label claim an impressive total milligram figure while a substantial portion of that weight is not mushroom material at all. Here is what CuratedFit fou

Most probiotic supplements have a transparency problem that is easy to miss. The label shows a total CFU count. Ten billion, twenty billion, fifty billion. It sounds specific. What it often does not show is how that total breaks down across the individual strains in the formula. Without that breakdown, there is no way to know whether the billions are distributed meaningfully across several strains or concentrated almost entirely in one, with the others present in amounts too

Most ginseng supplements on the market use raw or mildly processed Panax ginseng root extract. The active compounds, ginsenosides, are present. The question the label does not answer is whether they are present in a form the body can efficiently use. Life Extension Ginseng Energy Boost answers that question differently from most. What this product is A single vegetarian capsule providing 200 mg of GS15-4, a branded fermented Panax ginseng root extract trademarked by ILHWA N.A

Magnesium is one of the most widely taken supplements. It is also one of the most inconsistently formulated. Walk into any pharmacy and you will find magnesium products in half a dozen different forms. Oxide, citrate, glycinate, malate, taurate, threonate. The front of each pack makes broadly similar claims. The back of each pack tells a different story in terms of what you are actually getting and why. Here is what the CuratedFit Standard found when it reviewed Life Extensio

Most CoQ10 supplements sell you the oxidized form. They do not always tell you that. The distinction between ubiquinone (the oxidized form) and ubiquinol (the reduced, active form) is one of the more meaningful formulation decisions in the supplement category, and one of the least visible to a consumer reading a label. Here is what the CuratedFit Standard found when it reviewed Life Extension Super Ubiquinol CoQ10. Ubiquinone versus ubiquinol Coenzyme Q10 exists in two forms

The word proprietary on a supplement label is usually a warning sign. It typically means individual ingredient quantities are hidden behind a single combined total, making meaningful evaluation impossible. Life Extension Curcumin Elite uses the phrase "Curcumin Elite Proprietary CGM Blend" in its branding. It is also one of the more transparently formulated curcumin products reviewed in this catalogue. Those two things are not a contradiction. Here is why. What the label actu

Rhodiola Rosea is sold by dozens of brands. Most of them standardize to one compound. A smaller number standardize to two. Fewer still tell you whether the species on the label is actually the species in the capsule. Those distinctions sound technical. They are also exactly the kind of information that separates a meaningful evaluation from a marketing exercise. This is what the CuratedFit Standard found when it reviewed Life Extension Rhodiola Extract. What this product is A

Bacopa Monnieri has been used within the Ayurvedic tradition for centuries as a cognitive tonic. It is also one of the most inconsistently dosed botanical ingredients in the modern supplement market. Most bacopa products on sale today either do not disclose their standardization level, use a dose below what published human research has studied, or combine bacopa with multiple other ingredients inside a proprietary blend that prevents any meaningful evaluation. That is why mos
