Calculation Details
Coverage of Selected Weights44%
4 of 9 selected weight points have data. Missing values are excluded, not scored zero. This is not a measure of scientific confidence.
Each rating keeps its original scale and is also converted to 0–100: 4.4 / 5 becomes 88; 8.2 / 10 becomes 82. This puts numbers on one scale, but does not make different rating methods equivalent.
Your score = sum of (normalized value × your weight) ÷ sum of weights with data.

- Unknown is not false. Missing data is excluded from the score and lowers data coverage when you give it weight.
- Disclosure counts named roles, not the number of separate companies. One company can satisfy several roles only when the evidence supports each role.
- Coverage describes available inputs, not scientific confidence. Scores with different missing inputs may not be comparable.
- Review counts are shown for context. They do not automatically increase a retailer's influence. Sources may share reviews.
- Recall notices and interaction information stay separate. They cannot be averaged away by a high customer rating.
- Only matching product and formula records should be combined. A label redesign alone does not reset ratings; a formula change requires matching the evidence again.

Can I take Magnesium with Adagrasib?
Magnesium monitoring and correction of low levels may be needed during adagrasib treatment. Your oncology team should decide whether supplementation is necessary from your results and risk factors.
Scope: Adequate magnesium intake and clinician-directed replacement during oral adagrasib therapy. Dietary intake, oral supplements and treatment of clinically significant electrolyte abnormalities are distinct decisions.

Can I take Magnesium with Alendronate?
Keep oral magnesium apart from oral alendronate. Take alendronate first under its fasting instructions. Although the FOSAMAX label sets a 30-minute minimum before other oral products, NIH magnesium guidance advises at least two hours of separation; ask your pharmacist to apply the instructions to your product.
Scope: Evidence concerns the alendronate active moiety in oral alendronate sodium. The label explicitly expresses sodium-salt strength as the free-acid equivalent; this does not transfer recommendations to another bisphosphonate or injectable route.

Can I take Magnesium with Bictegravir?
Magnesium-containing antacids can substantially reduce bictegravir absorption. Take Biktarvy at least 2 hours before or 6 hours after an aluminum/magnesium antacid. Magnesium supplements also need a timing review, but the direct antacid results do not establish the same effect for every magnesium preparation.
Scope: Adult oral Biktarvy with magnesium-containing antacids or nutritional supplements. Direct evidence used magnesium hydroxide combined with aluminum hydroxide; magnesium glycinate, citrate and other stand-alone supplements were not separately tested.

Brand & Company
Who Makes, Packs & Distributes It?
One company may fill several roles. We identify each role separately from the available evidence.
Manufacturer
Not yet checkedThe available archive does not establish this role. Full packaging disclosure has not been checked.
Packer
Not yet checkedThe available archive does not establish this role. Full packaging disclosure has not been checked.
Distributor

A business identifier confirms which company a record refers to; it does not establish what work that company performs for this product.
How Label Disclosure Affects Your Score
Our transparency standard: We prioritize the ability to identify who manufactures and packs a product. The Transparency First preset gives these disclosures greater weight than customer ratings. This is our comparison preference, not an estimate of adulteration risk.
Manufacturer, packer, and distributor disclosure can each receive a weight in your comparison score. Identified roles score 100; a role confirmed as not disclosed on reviewed packaging scores 0. A role we have not checked stays Unknown and is excluded.
U.S. labeling rules require a named manufacturer, packer, or distributor, not disclosure of all three. An unqualified company name can indicate the manufacturer under the rule; it does not establish the packer or distributor. “Manufactured for” and “distributed by” describe different relationships.
This is a transparency preference, not a safety rating or a finding of noncompliance. It does not establish what information a regulator holds.
Read the U.S. labeling rule ↗FDA does not approve dietary supplements before they are marketed. Manufacturers and distributors are responsible for their products’ safety and compliance. FDA’s explanation ↗
A name search is not confirmation of a recall or a company match. Business identifiers and private contact details are not displayed.
