Ingredient Evidence

Clinical Research Behind Our Formulas

Pacific Formulations products are built around single ingredients, clearly stated forms, and practical daily servings. This research library highlights human clinical trials that used the same dose, a close dose, or a studied range related to the amount found in each formula.

Pacific-Born. Science-Driven.
How to Read This Page

Research Match, Clearly Labeled

Clinical trials do not always use the exact form, serving size, participant group, or study period found in a retail supplement. We label each study by how closely its daily amount matches the Pacific Formulations serving so you can review the evidence without assuming two formulas are identical.

A study listed here does not prove that every person will experience the same result. Trial findings apply to the tested ingredient, amount, population, study design, and duration.

Exact Dose The trial used the same total daily amount offered in our formula.
Close Dose The trial used an amount near our serving, but not the exact amount.
Studied Range Our serving sits within or near the dose range tested across the trial groups.

NMN Clinical Research

Pacific Formulations NMN provides 500 mg of nicotinamide mononucleotide in a two-capsule serving. Human studies have tested daily NMN intakes from 250 mg through 900 mg across several adult populations.

500 mg Our Daily Serving

The studies below support research into oral NMN, NAD-related markers, physical function, and tolerability. They do not establish NMN as a treatment for aging or any medical condition.

Dose-Response Trial in Healthy Middle-Aged Adults

Studied Range Randomized Trial
Daily Amounts 300, 600, or 900 mg
Duration 60 days
Participants 80 adults
Design Double-blind, placebo-controlled

Researchers compared three daily NMN amounts with placebo in healthy middle-aged adults. The study assessed blood NAD concentrations, physical performance measures, biological age estimates, and safety outcomes.

The 500 mg Pacific Formulations serving falls between the 300 mg and 600 mg study groups. This makes the trial relevant to the serving range, though it was not a direct test of a 500 mg dose or of the finished Pacific Formulations product.

Daily NMN and Blood NAD Levels

Close Dose Randomized Trial
Daily Amount 250 mg NMN
Duration 12 weeks
Participants 60 adults
Design Double-blind, placebo-controlled

This trial examined daily NMN intake, blood NAD metabolites, motor function tests, sleep measures, and stress-related questionnaires. The NMN group received 250 mg per day, which equals one Pacific Formulations capsule and half of the labeled serving.

Essential Mineral

Magnesium Glycinate Clinical Research

Both Pacific Formulations Magnesium Glycinate products provide 200 mg of elemental magnesium per serving. The powder uses magnesium bisglycinate, while the capsules provide elemental magnesium from magnesium glycinate.

200 mg Elemental Magnesium

Direct trials using exactly 200 mg of elemental magnesium as magnesium bisglycinate are limited. The closest form-specific randomized trial located used 250 mg of elemental magnesium from magnesium bisglycinate.

Magnesium Bisglycinate and Self-Reported Sleep Quality

Close Dose Same Form
Daily Amount 250 mg elemental magnesium
Form Magnesium bisglycinate
Participants 155 adults
Design Double-blind, placebo-controlled

Adults with self-reported poor sleep quality were assigned to magnesium bisglycinate or placebo. Researchers measured insomnia severity and related psychological questionnaires across the study period.

The study used the same mineral form as the Pacific Formulations powder and a daily elemental amount 50 mg above our serving. Results should not be treated as proof that a 200 mg serving will produce the same findings.

Oral Magnesium at a Comparable Daily Amount

Close Dose Different Form
Daily Amount 250 mg magnesium
Form Magnesium oxide
Duration 8 weeks
Design Double-blind, placebo-controlled

This trial tested 250 mg of daily magnesium in healthy middle-aged women and measured body composition and muscle strength. It offers context for a nearby elemental amount, but magnesium oxide differs from magnesium glycinate in form and absorption characteristics.

View the study on PubMed

The powder and capsule products share the same 200 mg elemental magnesium serving. A clinical trial on one delivery format does not prove that flavor ingredients, capsule materials, or the finished products were tested.

Hormone and Reproductive Wellness

Inositol Clinical Research

Pacific Formulations Inositol provides 2 g of myo-inositol and 50 mg of D-chiro-inositol per four-capsule serving. This creates a 40:1 ratio of myo-inositol to D-chiro-inositol.

2 g + 50 mg 40:1 Serving Ratio

Many clinical studies of the 40:1 combination use two servings per day, for a total daily intake of 4 g myo-inositol and 100 mg D-chiro-inositol. Our labeled serving supplies half of that common daily research amount.

Myo-Inositol and D-Chiro-Inositol in a 40:1 Ratio

Same Ratio Higher Daily Total
Daily Combination 40:1 MI to DCI
Research Area Ovarian and metabolic markers
Population Women with PCOS
Evidence Type Human clinical research

Published research has examined combined myo-inositol and D-chiro-inositol in a 40:1 ratio, with outcomes tied to menstrual regularity, ovarian function, hormone measures, and markers of insulin response in selected groups.

The ingredient ratio matches the Pacific Formulations formula. The total daily amount used in many studies is higher than our single four-capsule serving, so the results should not be presented as a direct test of our labeled daily intake.

Inositol Evidence Review for Polycystic Ovary Syndrome

Multiple Doses Systematic Review
Evidence Base Randomized clinical trials
Ingredients Myo-inositol and D-chiro-inositol
Daily Amounts Varied across trials
Publication JCEM, 2024

This systematic review assessed controlled trials of inositol for PCOS and helped inform the 2023 international evidence-based guideline update. The authors reported that dose, ratio, study quality, and outcomes varied across trials.

This source offers a broader view of the evidence and its limits. It should not be read as proof for one serving size or as a replacement for care from a qualified clinician.

Metabolic Wellness

Berberine Clinical Research

Pacific Formulations Berberine provides 1,200 mg of berberine HCl per two-capsule serving. Human trials commonly divide daily berberine intake across meals and have tested amounts near 1,000 to 1,500 mg per day.

1,200 mg Berberine HCl

We did not identify a strong single-ingredient randomized trial using exactly 1,200 mg of berberine HCl that cleanly matched the Pacific Formulations formula. The studies below used nearby daily amounts and are labeled as close-dose research.

Berberine in Adults With Metabolic Syndrome

Close Dose Berberine HCl
Daily Amount 1,500 mg
Dosing Schedule 500 mg, three times daily
Duration 3 months
Design Double-blind, placebo-controlled

Researchers studied berberine hydrochloride taken before meals and measured glucose, insulin, triglycerides, HDL cholesterol, waist measures, and other metabolic markers.

The trial used 300 mg more berberine per day than the Pacific Formulations serving. Its findings should not be treated as proof that 1,200 mg will produce the same outcome.

Six-Month Berberine Trial in Adults With Obesity and MASLD

Close Dose Randomized Trial
Daily Amount 1,000 mg
Duration 6 months
Population Adults without diabetes
Design Randomized clinical trial

This trial reported that 1 g of daily berberine did not reduce the primary measures of visceral fat area or liver fat in the full study group. The study also assessed safety and several secondary metabolic markers.

Including neutral or negative findings gives a more complete view of the evidence. A clinical research page should show where an ingredient did not meet the trial's main goal, not only where a favorable result was reported.

Berberine and Metabolic-Associated Fatty Liver Disease

Close Dose Placebo-Controlled
Daily Amount 1,500 mg
Duration 12 weeks
Participants 70 adults
Design Double-blind, placebo-controlled

Researchers measured anthropometric, liver, and metabolic outcomes after 12 weeks of berberine or placebo. This study used a nearby daily dose but focused on a clinical population, so its results should not be generalized to every healthy adult.

Performance and Strength

Creatine Monohydrate Clinical Research

Every size of Pacific Formulations Creatine Monohydrate provides 5 g of micronized creatine monohydrate per serving. The 30-, 100-, and 200-serving containers use the same ingredient and serving amount.

5 g Creatine Monohydrate

Five grams is one of the most commonly studied daily creatine amounts. It has been used in trials involving resistance training, body composition, strength, timing, and physical performance.

Five-Gram Creatine Timing Trial

Exact Dose Same Form
Daily Amount 5 g creatine monohydrate
Duration 8 weeks
Participants 34 trained adults
Design Double-blind, placebo-controlled

Resistance-trained men and women received placebo or 5 g of creatine monohydrate within one hour before or after training. Researchers assessed resistance-training adaptations and body composition.

The ingredient form and daily amount match the Pacific Formulations serving. The finished product itself was not tested, and the results apply to the study's trained population and exercise plan.

Established Creatine Loading and Maintenance Doses

5 g Maintenance Evidence Review
Loading Protocol About 0.3 g/kg/day
Loading Period 5 to 7 days
Maintenance About 3 to 5 g/day
Ingredient Creatine monohydrate

Published sports-medicine research describes a short loading phase followed by a lower daily maintenance amount. A loading phase raises muscle creatine stores faster, but regular maintenance dosing can also raise stores over a longer period.

Pacific Formulations provides 5 g per scoop, which sits at the upper end of the common daily maintenance range. The serving also makes a four-times-daily loading schedule easy to measure when used under the suggested protocol.

View the dosing review on PubMed

The serving is identical across all three container sizes. Buying a larger size changes the number of servings, not the ingredient amount in each scoop.

Skin and Connective Tissue

Collagen Peptides Clinical Research

Pacific Formulations Collagen Peptides provides 11 g of grass-fed collagen hydrolysate per scoop. Both the 12-serving and 41-serving containers use the same serving amount.

11 g Collagen Hydrolysate

Many collagen trials use 10 g per day, which is 1 g below the Pacific Formulations serving. Studies also vary by collagen source, peptide profile, molecular weight, participant group, and measured outcome.

Collagen Hydrolysate in a Six-Month Knee Study

Close Dose Hydrolyzed Collagen
Daily Amount 10 g collagen hydrolysate
Duration 6 months
Participants 250 adults
Design Randomized, double-blind

This multicenter trial studied 10 g of collagen hydrolysate per day in adults with primary knee osteoarthritis. Researchers assessed joint-related symptoms over six months.

The daily amount is close to the 11 g Pacific Formulations serving. The trial involved a diagnosed population and should not be used to claim that collagen treats arthritis or joint disease.

Collagen Peptides, Skin Hydration, and Collagen Density

Related Dose Placebo-Controlled
Ingredient Oral collagen peptides
Duration Up to 8 weeks
Measures Hydration and collagen density
Design Placebo-controlled trials

Two controlled trials measured skin hydration, dermal collagen density, and collagen fragmentation after daily oral collagen peptide intake. Reported findings included changes in measured skin hydration after eight weeks.

Peptide composition can differ between collagen ingredients, so research on a named or proprietary collagen peptide should not be treated as a direct test of every hydrolyzed collagen powder.

Systematic Review of Hydrolyzed Collagen and Skin Measures

Multiple Doses Systematic Review
Evidence Base Randomized controlled trials
Ingredient Hydrolyzed collagen
Measures Wrinkles, hydration, elasticity
Daily Amounts Varied by trial

This review gathered randomized, double-blind controlled trials that measured skin wrinkles, hydration, elasticity, and firmness after oral hydrolyzed collagen intake. It offers a broader view of the evidence but includes different collagen ingredients and serving amounts.

View the review on PubMed

The 12-serving and 41-serving products provide the same 11 g serving. Container size does not change the collagen amount, protein content, or suggested daily scoop.

Our Research Standard

What We Look for in Human Evidence

Supplement studies can differ in quality, size, duration, and relevance. We give the most weight to controlled human research and clearly separate exact-dose evidence from studies that use a nearby amount or a different ingredient form.

Human Participants

Animal and laboratory studies can help explain biological pathways, but they cannot predict a specific outcome in people. This page centers on published human research.

Clear Daily Amounts

We show the amount used in each study beside the Pacific Formulations serving. A nearby dose is marked as close rather than presented as an exact match.

Results With Context

We include study population, length, design, and key limits. A favorable finding in one group does not promise the same result for every user.

Simple Formulas. Clear Evidence.

Built Around Ingredients You Can Identify

Pacific Formulations focuses on single-ingredient formulas at clearly stated servings. This approach makes it easier to compare the label with published research, understand what you are taking, and build a routine around a defined daily amount.

Research continues to develop, and new findings may change how an ingredient is understood. Product use should stay within the label directions unless a qualified healthcare professional recommends a different plan based on your needs.
