Frequently Asked Questions

Is this safe to take every day? expand_more
Yes. Every ingredient is a nutrient your body uses continuously or a compound that supports ongoing biological processes. None are stimulants. None cause dependency. Benefits actually build over 1 to 3 months of consistent use, so daily use is how the product is designed to work.
How long before I notice something? expand_more
Most users report changes in energy and sleep quality starting 2 to 3 weeks. Cellular protection and antioxidant benefits build over 1 to 3 months. Skin changes are the slowest and follow the metabolic improvements.
I am over 60. Can I take this? expand_more
Yes. All ingredients are naturally occurring compounds the body already uses. No stimulants. Please note that this is a supplement and not a medicine. This is not meant to cure diseases. If you are pregnant or on medication, check with your doctor before taking this or any other supplements.
Why is it a powder, not capsules? expand_more
Because there are 8-9 ingredients at full clinical dosages. You cannot fit that into capsules without cutting doses or adding fillers. Powder was the only way to deliver everything at the amounts that research actually used.
What does it taste like? expand_more
Fruit punch. Sweetened with stevia and allulose. The flavour was refined over multiple rounds with 25 real customer testers. Mix one scoop with water and you are done in 30 seconds.
Can I take this with my other supplements? expand_more
In most cases, yes. It may actually replace several you are already taking. We have included specifics of which supplements our Longevity¹ Fuel can and cannot replace. If you are on prescription medication, check with your doctor.
How do I know what is actually in it? expand_more
Every batch is tested in a NABL-accredited lab. The reports are published at reports.theoakage.com. You do not need to trust our label. You can verify it.
Is the astaxanthin comparison real? 6000x more antioxidant power? expand_more
Yes. That figure comes from singlet oxygen quenching data published in peer-reviewed research. It specifically refers to AstaReal astaxanthin, the branded source we use. The comparison is to Vitamin C's antioxidant capacity in the same test conditions.
I already take Vitamin D. Do I need to keep taking it? expand_more
Longevity¹ Fuel contains D3 along with K2 and Magnesium, which most standalone D3 supplements do not include. If you switch to Fuel, you likely do not need a separate D3. But if you are on a specific prescribed dose, check with your doctor.

One scoop. 30 seconds. 8 systems protected.
