HelloPharmacist Scorecard of XCT Oil by Bulletproof

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Ingredient Transparency
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Capric and Caprylic Acid Triglycerides” is listed as a grouped ingredient — the label gives one combined amount (14 Gram(s)) without saying how much of each component you get.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Caprylic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 262 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

HelloPharmacist summaryFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Assessment coverage: 1 of 2 active ingredients matched to our full ingredient reviews (monographs). Based on the product label dated Dec 22, 2017.

General Statements

Don't fight it, fuel it. Is your body telling you it needs more fuel? Give it what it craves.

What Is XCT Oil? XCT Oil is not your average MCT oil. It's made exclusively from the two most easily metabolized fats in coconut oil, with zero lauric acid, which is harder to process and can slow you down. The result: High-performance fats your body can turn into energy faster, so you feel great. Love it or your money back.

Fat for fuel

High performance MCTs

This product is packaged in a non-BPA, recyclable HDPE bottle to reduce the environmental impacts of padding, packaging and shipping glass bottles.

Suggested/Recommended/Usage/Directions

XCT Oil is a flavorless oil that transforms any salad, smoothie or snack into a delicious, energy-rich performance fuel, more lasting than any refined sugar or carb. Use it on anything.

Directions Try one teaspoon at a time first and then build up over several days to a full 1-tablespoon serving, as often as you'd like. Just start small - too much too soon can upset your stomach. For low temperature cooking only. Do not heat above 320(0)F.
