Transparent Labs Prebiotic Greens review

A greens powder from a brand built on full disclosure labeling, sold in 30 serving tubs.

The label serving is Powder, one scoop.

Readers who want disclosure and a mid range price in the same product.

Full per ingredient amounts. The brand publishes fully disclosed labels across its product lines and states no proprietary blends on this page.

We keep organic certification, supplier documentation and finished product testing as separate fields. Where a manufacturer states something we cannot confirm from a primary source, we record it as a claim rather than a verified fact.

Certified organic: Not publicly verified. We have not confirmed a current certification statement for this product from a primary source.

• Supplier certificates of analysis: Not publicly verified. No published document from an identifiable source.
• Incoming ingredient testing: Not publicly verified. No published document from an identifiable source.
• Finished product third party testing: Informed Choice certified product, listed under Transparent Labs Prebiotic Greens.

These three layers are reported separately on purpose. A supplier document or an incoming ingredient check is not the same thing as an independent test of the finished product.

At the listed price of $45.99 for 30 servings, this works out to $1.53 per serving on the listed price, 30 serving tub basis. Promotions and subscription pricing change often.

The brand quotes a lower per serving figure than the list price divided by servings, which reflects subscription pricing.

• Ingredient quality18%5.9 / 10

  Weighted across the ingredient attributes: every ingredient named with its own amount (10). Organic certification carries the most weight, then whole food sourcing, then named amounts and freedom from artificial additives. Attributes we could not publicly verify are held at the neutral baseline of 5.0 out of 10 rather than left out, so an unverified attribute earns no credit.

• Nutrient density15%Not publicly verified

  Not scored. We have not verified a nutrition facts panel and a serving weight for this product, so nutritional substance cannot be measured.

• Label transparency14%10.0 / 10

  Label disclosure recorded as full per ingredient amounts, which scores 10 out of 10 on this criterion.

• Value per gram18%8.9 / 10

  $0.10 per gram of powder, scaled against the 8 products with both a verified price and a verified serving weight.

• Product per dollar5%5.4 / 10

  10.4 g of product per dollar, from the listed price and the total container weight, scaled against the 8 products where both are verified.

• Serving grams delivered5%10.0 / 10

  16 g delivered per label serving, scaled inside the greens powders group so scoops are compared with scoops and meals with meals. No verified nutrition panel yet, so the quantity is recorded as published without a density adjustment. This measures quantity delivered only; cost is handled by value per gram and ingredient sourcing by ingredient quality.

• Price per serving5%8.8 / 10

  $1.53 per label serving, scaled against the 11 products in the database with a verified price. A labeled serving is not a standard unit, which is why this criterion carries only 5% of the rubric.

• Testing and certifications10%10.0 / 10

  Finished product third party testing published: Informed Choice certified product, listed under Transparent Labs Prebiotic Greens..

• Packaging protection10%Not publicly verified

  Not publicly verified. We have not verified the container material and barrier properties from a source we can cite, so this criterion is withheld from the score rather than assumed.

How this figure is calculated. Each criterion is multiplied by its rubric weight and the total is divided by the full 100 points of the rubric. A criterion we could publicly verify earns the points its evidence supports. A criterion we could not verify is held at the neutral baseline of 5.0 out of 10 and still occupies its full weight, so unverified evidence can never be excluded from the division and cannot earn the credit a verified strength earns.

For Transparent Labs Prebiotic Greens the verified criteria contribute 5.9 x 18 + 10.0 x 14 + 8.9 x 18 + 5.4 x 5 + 10.0 x 5 + 8.8 x 5 + 10.0 x 10 = 627.4 points. The 2 criteria that are not publicly verified cover 25 points of rubric weight and contribute 5.0 x 25 = 125.0 points at the baseline. The total divided by 100 gives 7.5 out of 10.

75% of the rubric weight here is backed by publicly verified evidence. Not publicly verified means Greens Powder Guide could not independently verify this criterion from publicly available evidence. It does not necessarily mean the brand does not meet the criterion, which is why the baseline sits at the middle of the scale rather than at zero.
