PRO Therapeutics Supplements: Frequently Asked Questions
Common Questions About Combining, Timing, Safety, and Testing
PRO Sports Medicine Learning Center
Introduction
Throughout this series, we have explained each PRO Therapeutics formula ingredient by ingredient. This final chapter answers the questions patients ask most often about choosing, combining, and safely using PRO supplements.
Getting Started
Where should I start?
For most adults, PRO FOUNDATIONS Daily Multi is the starting point because it establishes a daily micronutrient baseline. From there, OMEGA+ is a common next step for people who eat little fatty fish, and RESTORE for people with low magnesium intake or demanding training. PRO METABOLIC, PRO NAC, and the high-potency vitamin D3 products are more targeted and are best chosen with your provider.
Do I need all of them?
No. The formulas are designed to work together, but most people need only some of them. The right combination depends on your diet, goals, lab results, and medications.
Why are there 30-day and 90-day options?
Nutritional strategies work through consistent daily use. A 90-day supply supports three months of consistency, a practical window before reassessing with your provider, often with repeat lab work. It is a convenience and adherence choice, not a clinical requirement.
Combining Formulas
Can I take FOUNDATIONS, OMEGA+, RESTORE, and METABOLIC together?
They were designed as a system with minimal overlap. However, combining them changes your total intake of some nutrients, and METABOLIC in particular requires a medication review. Discuss your full plan with your provider.
Which nutrients overlap?
The main overlaps are magnesium (100 mg in FOUNDATIONS and 200 mg in RESTORE, for 300 mg combined, under the 350 mg supplemental upper limit), vitamin D3 (1,000 IU in FOUNDATIONS plus any high-potency vitamin D3 product), and vitamin K2 (120 mcg in FOUNDATIONS plus 100 mcg in Vitamin D3 10,000 IU with K2). Also count any other multivitamins, calcium, zinc, or vitamin D products you use.
Can I take FOUNDATIONS with Vitamin D3 10,000 IU or 50,000 IU?
Possibly, but only with your provider's knowledge. The 1,000 IU in FOUNDATIONS adds to your total vitamin D intake, which your provider should account for when setting your high-potency dose and timing your follow-up test.
Can I take Vitamin D3 10,000 IU and 50,000 IU together?
Not unless your provider specifically directs it. They are alternative high-potency regimens, one daily and one weekly, and taking both would greatly increase total vitamin D intake.
Timing
When should I take each product?
FOUNDATIONS: two capsules daily, ideally with a meal.
OMEGA+: two soft gels daily with food, ideally a meal containing fat.
RESTORE: two capsules daily, preferably in the evening.
METABOLIC: two capsules daily with food; some people split them between two meals.
NAC: one or two capsules daily with food.
Vitamin D3 10,000 IU with K2: one capsule daily with food and a glass of water, only when directed by your provider.
Vitamin D3 50,000 IU: one capsule once weekly with a meal, only when directed by your provider.
Should I separate magnesium from my medications?
Yes, for certain medications. Magnesium can reduce absorption of some antibiotics (tetracyclines and fluoroquinolones) and bisphosphonates. Ask your pharmacist or provider how far apart to take them.
Safety and Interactions
Which products need the most caution with medications?
PRO METABOLIC: berberine, ALA, and cinnamon can lower blood sugar and add to the effects of diabetes medications, including GLP-1 medications. Berberine can also affect how the liver processes many drugs.
PRO OMEGA+: omega-3s can affect bleeding risk with blood thinners, and CoQ10 may reduce warfarin's effect.
Vitamin K2 (in FOUNDATIONS and Vitamin D3 10,000 IU with K2): vitamin K counteracts warfarin; use only with your prescriber's approval and INR monitoring.
PRO FOUNDATIONS: vitamin K can affect warfarin.
PRO NAC: can enhance the effects of nitroglycerin and related nitrates.
Vitamin D3 high-potency products: interact with calcium balance and with medications such as thiazide diuretics and digoxin.
Are these products safe during pregnancy or breastfeeding?
Consult your healthcare professional before using any supplement while pregnant or nursing. Berberine, in PRO METABOLIC, should not be used during pregnancy or breastfeeding.
What about surgery?
Tell your surgical team about every supplement you take. Omega-3s, NAC, and METABOLIC are among the products your provider may ask you to pause before a procedure.
Can supplements affect my lab results?
Yes. Biotin in FOUNDATIONS can interfere with some hormone and thyroid tests. High-potency vitamin D changes vitamin D and possibly calcium results. METABOLIC and OMEGA+ may change glucose and lipid markers, which is part of why monitoring them is useful. Tell your provider everything you take before testing.
What side effects should I watch for?
Digestive upset is the most common side effect across supplements, especially with berberine, magnesium, NAC, and fish oil. For vitamin D, watch for signs of high calcium: nausea, vomiting, excessive thirst, frequent urination, weakness, or confusion. For FOUNDATIONS, tingling or numbness may relate to vitamin B6 and should be reported. Stop and contact your provider if you have concerns.
Testing and Results
Why does PRO emphasize lab testing with supplements?
Many nutrients and markers can be measured. Testing shows whether you need a high-potency product, guides the dose, confirms the response, and prevents excess. The PRO Lab Panels make this possible at home.
Which panels pair with which products?
Vitamin D3 products: vitamin D in the Core Health Panel; calcium and kidney function in the Performance Panel.
PRO METABOLIC: HbA1c, C-peptide, lipids, ApoB, and liver markers in the GLP & Cardio Panel.
PRO OMEGA+: triglycerides and lipids in the Core Health, GLP & Cardio, or Performance Panels.
PRO FOUNDATIONS: vitamin D, ferritin, B12, and folate in the Core Health and Performance Panels.
PRO RESTORE: kidney function in the GLP & Cardio and Performance Panels, relevant to magnesium safety.
How soon will I notice a difference?
Supplements support normal physiology and generally work gradually. Some changes, such as improved vitamin D levels or triglycerides, are best judged with repeat testing after several weeks to a few months. If you are not noticing benefits, review your plan with your provider rather than increasing doses.
Quality and Regulation
Are PRO Therapeutics products FDA-approved?
No dietary supplement is FDA-approved. In the United States, the FDA does not approve supplements for safety or effectiveness before they are sold. Supplement labels may describe support for normal body structure or function but may not claim to diagnose, treat, cure, or prevent disease.
Does research on an ingredient prove the product works?
No. Research on individual ingredients, often at different doses or in specific populations, does not establish that a finished product will produce the same results. This series describes ingredient evidence honestly so you can set realistic expectations.
Can supplements replace my medications?
No. PRO Therapeutics products are not a substitute for prescribed treatment. Never stop or change a medication without speaking to your provider.
Bringing It All Together
PRO Therapeutics is built on a simple idea: start with the foundation, add targeted support where it is needed, and use objective data to guide decisions. Choose products with your goals and lab results in mind, watch cumulative doses, review medications with your provider, and reassess regularly. That approach keeps supplementation purposeful, safe, and connected to the rest of your care at PRO Sports Medicine.

Clinical Perspective
The most common supplement problems are not exotic interactions but simple ones: duplicated nutrients across products, unmonitored high-dose vitamin D, and supplements a provider did not know about. A short, intentional list of products, a current medication review, and periodic laboratory testing prevent most of them and make it far easier to tell what is actually helping.
